The architecture 'mirage' is composed of: - 2 Intel Xeon X5650 @2.67GHz, thus 12 CPU cores - MKL 11.1.3 - 3 NVidia GF100 Tesla M2070, thus 3 GPUs - CUDA 6.0 - Magma 1.6.0 The architecture 'attila' is composed of: - 2 Intel Xeon X5650 @2.67GHz, thus 12 CPU cores - OpenBlas 0.2.12-1 - 3 NVidia GF100 Tesla C2050 / C2070, thus 3 GPUs - CUDA 6.0 To use performance models stored in this directory, one needs to set the environment variable 'STARPU_PERF_MODEL_DIR' to the location of the directory, e.g.: export STARPU_PERF_MODEL_DIR=.../tools/perfmodels/sampling and then select the desired

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

Introduction || ++=================++ +--------------------- | I.a. What is StarPU? StarPU is a runtime system that offers support for heterogeneous multicore machines. While many efforts are devoted to design efficient computation kernels for those architectures (e.g. to implement BLAS kernels on GPUs), StarPU not only takes care of offloading such kernels (and implementing data coherency across the machine), but it also makes sure the kernels are executed as efficiently as possible. +------------------------ | I.b. What StarPU is not StarPU is not a new language, and it does not extend existing languages either. StarPU does not help to write computation kernels. +--------------------------------- | I.c. (How) Could StarPU help me? While StarPU will not make it easier to write computation kernels, it does simplify their actual offloading as StarPU handle most low level aspects transparently. Obviously, it is crucial to have efficient kernels, but it must be noted that the way those kernels are mapped and scheduled onto the computational resources also affect the overall performance to a great extent. StarPU is especially helpful when considering multiple heterogeneous processing resources: statically mapping and synchronizing tasks in such a heterogeneous environment is already very difficult, making it in a portable way is virtually impossible. On the other hand, the scheduling capabilities of StarPU makes it possible to easily exploit all processors at the same time while taking advantage of their specificities in a portable fashion. ++==================++ || II. Requirements || ++==================++ * make * gcc (version >= 4.1) * if CUDA support is enabled * CUDA (version >= 2.2) * CUBLAS (version >= 2.2) * if OpenCL support is enabled * AMD SDK >= 2.3 if AMD driver is used * CUDA >= 3.2 if NVIDIA driver is used * extra requirements for the svn version (we usually use the Debian testing versions) * autoconf (version >= 2.60) * automake * makeinfo * libtool (version >= 2) * Remark: It is strongly recommanded that you also install the hwloc library before installing StarPU. This permits StarPU to actually map the processing units according to the machine topology. For more details on hwloc, see http://www.open-mpi.org/projects/hwloc/ . * To build the StarPU-Top tool the following packages (along with their development files) are also required: * libqt4-dev >= 4.7 * libqt4-network * libqt4-opengl * libqt4-sql * qt4-qmake ++=====================++ || III. Getting StarPU || ++=====================++ StarPU is available on https://gforge.inria.fr/projects/starpu/. The project's SVN repository can be checked out through anonymous access with the following command(s). $ svn checkout svn://scm.gforge.inria.fr/svn/starpu/trunk $ svn checkout --username anonsvn https://scm.gforge.inria.fr/svn/starpu/trunk The password is 'anonsvn' ++=============================++ || IV. Building and Installing || ++=============================++ +--------------------------- | IV.a. For svn version only $ ./autogen.sh +----------------------- | IV.b. For all versions $ ./configure $ make $ make install +--------------------- | IV.c. Windows build: StarPU can be built using MinGW or Cygwin. To avoid the cygwin dependency, we provide MinGW-built binaries. The build process produces libstarpu.dll, libstarpu.def, and libstarpu.lib, which should be enough to use it from e.g. Microsoft Visual Studio. Update the video drivers to the latest stable release available for your hardware. Old ATI drivers (< 2.3) contain bugs that cause OpenCL support in StarPU to hang or exhibit incorrect behaviour. For details on the Windows build process, see the INSTALL file. ++==================++ || V. Documentation || ++==================++ Doxygen documentation is available in doc/doxygen. If the doxygen tools are available on the machine, pdf and html documentation can be generated by running $ make -C doc ++============++ || VI. Trying || ++============++ Some examples ready to run are installed into $prefix/lib/starpu/{examples,mpi} ++==============++ || VII. Upgrade || ++==============++ To upgrade your source code from older version (there were quite a few renamings), use the tools/dev/rename.sh script ++===============++ || VIII.

It supports different display styles, interpolation ( f.e. spline ) and symbols. \par Usage
a) Assign curve properties
When a curve is created, it is configured to draw black solid lines with in Lines style and no symbols. You can change this by calling setPen(), setStyle() and setSymbol().
b) Connect/Assign data.
QwtPlotCurve gets its points using a QwtData object offering a bridge to the real storage of the points ( like QAbstractItemModel ). There are several convenience classes derived from QwtData, that also store the points inside ( like QStandardItemModel ). QwtPlotCurve also offers a couple of variations of setData(), that build QwtData objects from arrays internally.
c) Attach the curve to a plot
See QwtPlotItem::attach()
\par Example: see examples/bode \sa QwtPointSeriesData, QwtSymbol, QwtScaleMap */ class QWT_EXPORT QwtPlotCurve: public QwtPlotSeriesItem { public: /*! Curve styles. - NoCurve\n Don't draw a curve. Note: This doesn't affect the symbols. - Lines\n Connect the points with straight lines. The lines might be interpolated depending on the 'Fitted' attribute.

Contents ========= * Installing StarPU on a Unix machine * Installing StarPU on Windows * Running StarPU Applications on Microsoft Visual C Installing StarPU on a Unix machine ------------------------------------ $ ./autogen.sh # If running the SVN version $ ./configure --prefix= $ make $ make install Installing StarPU on Windows ---------------------------- If you are building from a tarball downloaded from the website, you can skip the cygwin part. 1. Install cygwin http://cygwin.com/install.html Make sure the following packages are available: - (Devel)/subversion - (Devel)/libtool - (Devel)/gcc - (Devel)/make - your favorite editor (vi, emacs, ...) - (Devel)/gdb - (Archive)/zip - (Devel)/pkg-config 2. Install mingw http://www.mingw.org/ 3. Install hwloc (not mandatory, but strongly recommended) http://www.open-mpi.org/projects/hwloc Be careful which version you are installing. Even if your machine runs windows 64 bits, if you are running a 32 bits mingw (check the output of the command uname -a), you will need to install the 32 bits version of hwloc. 4. Install Microsoft Visual C++ Studio Express http://www.microsoft.com/express/Downloads Add in your path the following directories. (adjusting where necessary for the Installation location according to VC version and on 64 and 32bit Windows versions) On cygwin, with Visual C++ 2010 e.g.; export PATH="/cygdrive/c/Program Files (x86)/Microsoft Visual Studio 10.0/Common7/IDE":$PATH export PATH="/cygdrive/c/Program Files (x86)/Microsoft Visual Studio 10.0/VC/bin":$PATH On MingW, with Visual C++ 2010, e.g.; export PATH="/c/Program Files (x86)/Microsoft Visual Studio 10.0/Common7/IDE":$PATH export PATH="/c/Program Files (x86)/Microsoft Visual Studio 10.0/VC/bin":$PATH Try to call , and without any option to make sure these dump their help output with a series of options, otherwise no .def or .lib file will be produced. 5. Install GPU Drivers (not mandatory) 5.1 Install Cuda http://developer.nvidia.com/object/cuda_3_2_downloads.html You need to install at least the CUDA toolkit. libtool is not able to find the libraries automatically, you need to make some copies: copy c:\cuda\lib\cuda.lib c:\cuda\lib\libcuda.lib copy c:\cuda\lib\cudart.lib c:\cuda\lib\libcudart.lib copy c:\cuda\lib\cublas.lib c:\cuda\lib\libcublas.lib copy c:\cuda\lib\cufft.lib c:\cuda\lib\libcufft.lib copy c:\cuda\lib\OpenCL.lib c:\cuda\lib\libOpenCL.lib (and if the version of your CUDA driver is >= 3.2) copy c:\cuda\lib\curand.lib c:\cuda\lib\libcurand.lib Add the CUDA bin directory in your path export PATH=/cygdrive/c/CUDA/bin:$PATH Since we build code using CUDA headers with gcc instead of Visual studio, a fix is needed: c:\cuda\include\host_defines.h has a bogus CUDARTAPI definition which makes linking fail completely. Replace the first occurence of #define CUDARTAPI with #ifdef _WIN32 #define CUDARTAPI __stdcall #else #define CUDARTAPI #endif While at it, you can also comment the __cdecl definition to avoid spurious warnings. 5.2 Install OpenCL http://developer.nvidia.com/object/opencl-download.html You need to download the NVIDIA Drivers for your version of Windows. Executing the file will extract all files in a given directory. The the driver installation will start, it will fail if no compatibles drivers can be found on your system. Anyway, you should copy the *.dl_ files from the directory (extraction path) in the bin directory of the CUDA installation directory (the directory should be v3.2/bin/) 5.3 Install MsCompress http://gnuwin32.sourceforge.net/packages/mscompress.htm Go in the CUDA bin directory, uncompress .dl_ files and rename them in .dll files cp /cygdrive/c/NVIDIA/DisplayDriver/190.89/International/*.dl_ . for i in *.dl_ ; do /cygdrive/c/Program\ Files/GnuWin32/bin/msexpand.exe $i ; mv ${i%_} ${i%_}l ; done If you are building from a tarball downloaded from the website, you can skip the autogen.sh part. 6. Start autogen.sh from cygwin cd starpu-trunk ./autogen.sh 7. Start a MinGW shell /cygdrive/c/MinGW/msys/1.0/bin/sh.exe --login -i 8. Configure, make, install from MinGW If you have a non-english version of windows, use export LANG=C else libtool has troubles parsing the translated output of the toolchain. cd starpu-trunk mkdir build cd build ../configure --prefix=$PWD/target \ --with-hwloc= \ --with-cuda-dir= \ --with-cuda-lib-dir=/lib/Win32 \ --with-opencl-dir= --disable-build-doc --disable-build-examples --enable-quick-check make make check # not necessary but well advised make install The option --disable-build-doc is necessary if you do not have a working TeX binary installed as it is needed by texi2dvi to build the documentation. To fasten the compilation process, the option --disable-build-examples may also be used to disable the compilation of the applications in the examples directory. Only the applications in the test directory will be build. Also convert a couple of files to CRLF: sed -e 's/$/'$'\015'/ < README > $prefix/README.txt sed -e 's/$/'$'\015'/ < AUTHORS > $prefix/AUTHORS.txt sed -e 's/$/'$'\015'/ < COPYING.LGPL > $prefix/COPYING.LGPL.txt 9. If you want your StarPU installation to be standalone, you need to copy the DLL files from hwloc, Cuda, and OpenCL into the StarPU installation bin directory, as well as MinGW/bin/libpthread*dll cp /bin/*dll target/bin cp /bin/*dll target/bin cp /cygdrive/c/MinGW/bin/libpthread*dll target/bin and set the StarPU bin directory in your path. export PATH=/bin:$PATH Running StarPU Applications on Microsoft Visual C ------------------------------------------------- Batch files are provided to run StarPU applications under Microsoft Visual C. They are installed in path_to_starpu/bin/mvsc. To execute a StarPU application, you first need to set the environment variable STARPUPATH. c:\....> cd c:\cygwin\home\ci\starpu\ c:\....> set STARPUPATH=c:\cygwin\home\ci\starpu\ c:\....> cd bin\mvsc c:\....> starpu_open.bat starpu_simple.c The batch script will run Microsoft Visual C with a basic project file to run the given application. The batch script starpu_clean.bat can be used to delete all compilation generated files.

Field Documentation

starpu_sched_policy::init_sched

Initialize the scheduling policy.

starpu_sched_policy::deinit_sched

Cleanup the scheduling policy.

starpu_sched_policy::push_task

Insert a task into the scheduler.

starpu_sched_policy::push_task_notify

Notify the scheduler that a task was pushed on a given worker. This method is called when a task that was explicitly assigned to a worker becomes ready and is about to be executed by the worker. This method therefore permits to keep the state of the scheduler coherent even when StarPU bypasses the scheduling strategy.

starpu_sched_policy::pop_task
read

Get a task from the scheduler. The mutex associated to the worker is already taken when this method is called. If this method is defined as NULL, the worker will only execute tasks from its local queue. In this case, the push_task method should use the starpu_push_local_task method to assign tasks to the different workers.

starpu_sched_policy::pop_every_task
read

Remove all available tasks from the scheduler (tasks are chained by the means of the field starpu_task::prev and starpu_task::next). The mutex associated to the worker is already taken when this method is called. This is currently not used.

starpu_sched_policy::pre_exec_hook

Optional field. This method is called every time a task is starting.

starpu_sched_policy::post_exec_hook

Optional field. This method is called every time a task has been executed.

starpu_sched_policy::add_workers

Initialize scheduling structures corresponding to each worker used by the policy.

starpu_sched_policy::remove_workers

Deinitialize scheduling structures corresponding to each worker used by the policy.

starpu_sched_policy::policy_name

Optional field. Name of the policy.

starpu_sched_policy::policy_description

Optional field. Human readable description of the policy.

Function Documentation

struct starpu_sched_policy ** starpu_sched_get_predefined_policies ( )
read

Return an NULL-terminated array of all the predefined scheduling policies.

void starpu_worker_get_sched_condition ( int  workerid,
starpu_pthread_mutex_t **  sched_mutex,
starpu_pthread_cond_t **  sched_cond 
)

When there is no available task for a worker, StarPU blocks this worker on a condition variable. This function specifies which condition variable (and the associated mutex) should be used to block (and to wake up) a worker. Note that multiple workers may use the same condition variable. For instance, in the case of a scheduling strategy with a single task queue, the same condition variable would be used to block and wake up all workers.

int starpu_sched_set_min_priority ( int  min_prio)

TODO: check if this is correct Defines the minimum task priority level supported by the scheduling policy. The default minimum priority level is the same as the default priority level which is 0 by convention. The application may access that value by calling the function starpu_sched_get_min_priority(). This function should only be called from the initialization method of the scheduling policy, and should not be used directly from the application.

int starpu_sched_set_max_priority ( int  max_prio)

TODO: check if this is correct Defines the maximum priority level supported by the scheduling policy. The default maximum priority level is 1. The application may access that value by calling the function starpu_sched_get_max_priority(). This function should only be called from the initialization method of the scheduling policy, and should not be used directly from the application.

int starpu_sched_get_min_priority ( void  )

TODO: check if this is correct Returns the current minimum priority level supported by the scheduling policy

int starpu_sched_get_max_priority ( void  )

TODO: check if this is correct Returns the current maximum priority level supported by the scheduling policy

int starpu_push_local_task ( int  workerid,
struct starpu_task *  task,
int  back 
)

The scheduling policy may put tasks directly into a worker’s local queue so that it is not always necessary to create its own queue when the local queue is sufficient. If back is not 0, task is put at the back of the queue where the worker will pop tasks first. Setting back to 0 therefore ensures a FIFO ordering.

int starpu_push_task_end ( struct starpu_task *  task)

This function must be called by a scheduler to notify that the given task has just been pushed.

int starpu_worker_can_execute_task ( unsigned  workerid,
struct starpu_task *  task,
unsigned  nimpl 
)

Check if the worker specified by workerid can execute the codelet. Schedulers need to call it before assigning a task to a worker, otherwise the task may fail to execute.

double starpu_timing_now ( void  )

Return the current date in micro-seconds.

uint32_t starpu_task_footprint ( struct starpu_perfmodel *  model,
struct starpu_task *  task,
enum starpu_perfmodel_archtype  arch,
unsigned  nimpl 
)

Returns the footprint for a given task

double starpu_task_expected_length ( struct starpu_task *  task,
enum starpu_perfmodel_archtype  arch,
unsigned  nimpl 
)

Returns expected task duration in micro-seconds.

double starpu_worker_get_relative_speedup ( enum starpu_perfmodel_archtype  perf_archtype)

Returns an estimated speedup factor relative to CPU speed

double starpu_task_expected_data_transfer_time ( unsigned  memory_node,
struct starpu_task *  task 
)

Returns expected data transfer time in micro-seconds.

double starpu_data_expected_transfer_time ( starpu_data_handle_t  handle,
unsigned  memory_node,
enum starpu_data_access_mode  mode 
)

Predict the transfer time (in micro-seconds) to move handle to a memory node

double starpu_task_expected_power ( struct starpu_task *  task,
enum starpu_perfmodel_archtype  arch,
unsigned  nimpl 
)

Returns expected power consumption in J

double starpu_task_expected_conversion_time ( struct starpu_task *  task,
enum starpu_perfmodel_archtype  arch,
unsigned  nimpl 
)

Returns expected conversion time in ms (multiformat interface only)

int starpu_get_prefetch_flag ( void  )

Whether STARPU_PREFETCH was set

int starpu_prefetch_task_input_on_node ( struct starpu_task *  task,
unsigned  node 
)

Prefetch data for a given task on a given node

void starpu_sched_ctx_worker_shares_tasks_lists ( int  workerid,
int  sched_ctx_id 
)

The scheduling policies indicates if the worker may pop tasks from the list of other workers or if there is a central list with task for all the workers

Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others.

    This License is a kind of ``copyleft'', which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software.

    We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference.

  2. APPLICABILITY AND DEFINITIONS

    This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The ``Document'', below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as ``you''. You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law.

    A ``Modified Version'' of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language.

    A ``Secondary Section'' is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them.

    The ``Invariant Sections'' are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none.

    The ``Cover Texts'' are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words.

    A ``Transparent'' copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not ``Transparent'' is called ``Opaque''.

    Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only.

    The ``Title Page'' means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, ``Title Page'' means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text.

    The ``publisher'' means any person or entity that distributes copies of the Document to the public.

    A section ``Entitled XYZ'' means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as ``Acknowledgements'', ``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' of such a section when you modify the Document means that it remains a section ``Entitled XYZ'' according to this definition.

    The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License.

  3. VERBATIM COPYING

    You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3.

    You may also lend copies, under the same conditions stated above, and you may publicly display copies.

  4. COPYING IN QUANTITY

    If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects.

    If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages.

    If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public.

    It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document.

  5. MODIFICATIONS

    You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version:

    1. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission.
    2. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement.
    3. State on the Title page the name of the publisher of the Modified Version, as the publisher.
    4. Preserve all the copyright notices of the Document.
    5. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices.
    6. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below.
    7. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice.
    8. Include an unaltered copy of this License.
    9. Preserve the section Entitled ``History'', Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled ``History'' in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence.
    10. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the ``History'' section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission.
    11. For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein.
    12. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles.
    13. Delete any section Entitled ``Endorsements''. Such a section may not be included in the Modified Version.
    14. Do not retitle any existing section to be Entitled ``Endorsements'' or to conflict in title with any Invariant Section.
    15. Preserve any Warranty Disclaimers.

    If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles.

    You may add a section Entitled ``Endorsements'', provided it contains nothing but endorsements of your Modified Version by various parties—for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard.

    You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one.

    The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version.

  6. COMBINING DOCUMENTS

    You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers.

    The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work.

    In the combination, you must combine any sections Entitled ``History'' in the various original documents, forming one section Entitled ``History''; likewise combine any sections Entitled ``Acknowledgements'', and any sections Entitled ``Dedications''. You must delete all sections Entitled ``Endorsements.''

  7. COLLECTIONS OF DOCUMENTS

    You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects.

    You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document.

  8. AGGREGATION WITH INDEPENDENT WORKS

    A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an ``aggregate'' if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document.

    If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate.

  9. TRANSLATION

    Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail.

    If a section in the Document is Entitled ``Acknowledgements'', ``Dedications'', or ``History'', the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title.

  10. TERMINATION

    You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License.

    However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.

    Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.

    Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it.

  11. FUTURE REVISIONS OF THIS LICENSE

    The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See http://www.gnu.org/copyleft/.

    Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License ``or any later version'' applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Document.

  12. RELICENSING

    ``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A ``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the site means any set of copyrightable works thus published on the MMC site.

    ``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization.

    ``Incorporate'' means to publish or republish a Document, in whole or in part, as part of another Document.

    An MMC is ``eligible for relicensing'' if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008.

    The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing.

ADDENDUM: How to use this License for your documents

To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page:

Copyright (C) year your name. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled ``GNU Free Documentation License''.

If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the ``with...Texts.'' line with this:

with the Invariant Sections being list their titles, with the Front-Cover Texts being list, and with the Back-Cover Texts being list.

If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation.

If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.

Detailed Description

This section describes the interface to manipulate codelets and tasks.

Data Structure Documentation

struct starpu_codelet

The codelet structure describes a kernel that is possibly implemented on various targets. For compatibility, make sure to initialize the whole structure to zero, either by using explicit memset, or the function starpu_codelet_init(), or by letting the compiler implicitly do it in e.g. static storage case.

Field Documentation

starpu_codelet::where

Optional field to indicate which types of processing units are able to execute the codelet. The different values STARPU_CPU, STARPU_CUDA, STARPU_OPENCL can be combined to specify on which types of processing units the codelet can be executed. STARPU_CPU|STARPU_CUDA for instance indicates that the codelet is implemented for both CPU cores and CUDA devices while STARPU_OPENCL indicates that it is only available on OpenCL devices. If the field is unset, its value will be automatically set based on the availability of the XXX_funcs fields defined below. It can also be set to STARPU_NOWHERE to specify that no computation has to be actually done.

starpu_codelet::can_execute

Define a function which should return 1 if the worker designated by workerid can execute the nimplth implementation of the given task, 0 otherwise.

starpu_codelet::type

Optional field to specify the type of the codelet. The default is STARPU_SEQ, i.e. usual sequential implementation. Other values (STARPU_SPMD or STARPU_FORKJOIN declare that a parallel implementation is also available. See Parallel Tasks for details.

starpu_codelet::max_parallelism

Optional field. If a parallel implementation is available, this denotes the maximum combined worker size that StarPU will use to execute parallel tasks for this codelet.

starpu_codelet::cpu_func
Deprecated:
Optional field which has been made deprecated. One should use instead the field starpu_codelet::cpu_funcs.
starpu_codelet::cuda_func
Deprecated:
Optional field which has been made deprecated. One should use instead the starpu_codelet::cuda_funcs field.
starpu_codelet::opencl_func
Deprecated:
Optional field which has been made deprecated. One should use instead the starpu_codelet::opencl_funcs field.
starpu_codelet::cpu_funcs

Optional array of function pointers to the CPU implementations of the codelet. It must be terminated by a NULL value. The functions prototype must be:

void cpu_func(void *buffers[], void *cl_arg)

The first argument being the array of data managed by the data management library, and the second argument is a pointer to the argument passed from the field starpu_task::cl_arg. If the field starpu_codelet::where is set, then the field starpu_codelet::cpu_funcs is ignored if STARPU_CPU does not appear in the field starpu_codelet::where, it must be non-null otherwise.

starpu_codelet::cuda_funcs

Optional array of function pointers to the CUDA implementations of the codelet. It must be terminated by a NULL value. The functions must be host-functions written in the CUDA runtime API. Their prototype must be:

void cuda_func(void *buffers[], void *cl_arg)

If the field starpu_codelet::where is set, then the field starpu_codelet::cuda_funcs is ignored if STARPU_CUDA does not appear in the field starpu_codelet::where, it must be non-null otherwise.

starpu_codelet::opencl_funcs

Optional array of function pointers to the OpenCL implementations of the codelet. It must be terminated by a NULL value. The functions prototype must be:

void opencl_func(void *buffers[], void *cl_arg)

If the field starpu_codelet::where field is set, then the field starpu_codelet::opencl_funcs is ignored if STARPU_OPENCL does not appear in the field starpu_codelet::where, it must be non-null otherwise.

starpu_codelet::nbuffers

Specify the number of arguments taken by the codelet. These arguments are managed by the DSM and are accessed from the void *buffers[] array. The constant argument passed with the field starpu_task::cl_arg is not counted in this number. This value should not be above STARPU_NMAXBUFS.

starpu_codelet::modes

Is an array of starpu_data_access_mode. It describes the required access modes to the data neeeded by the codelet (e.g. STARPU_RW). The number of entries in this array must be specified in the field starpu_codelet::nbuffers, and should not exceed STARPU_NMAXBUFS. If unsufficient, this value can be set with the configure option --enable-maxbuffers.

starpu_codelet::dyn_modes

Is an array of starpu_data_access_mode. It describes the required access modes to the data needed by the codelet (e.g. STARPU_RW). The number of entries in this array must be specified in the field starpu_codelet::nbuffers. This field should be used for codelets having a number of datas greater than STARPU_NMAXBUFS (see Setting The Data Handles For A Task). When defining a codelet, one should either define this field or the field starpu_codelet::modes defined above.

starpu_codelet::specific_nodes

Default value is 0. If this flag is set, StarPU will not systematically send all data to the memory node where the task will be executing, it will read the starpu_codelet::nodes or starpu_codelet::dyn_nodes array to determine, for each data, whether to send it on the memory node where the task will be executing (-1), or on a specific node (!= -1).

starpu_codelet::nodes

Optional field. When starpu_codelet::specific_nodes is 1, this specifies the memory nodes where each data should be sent to for task execution. The number of entries in this array is starpu_codelet::nbuffers, and should not exceed STARPU_NMAXBUFS.

starpu_codelet::dyn_nodes

Optional field. When starpu_codelet::specific_nodes is 1, this specifies the memory nodes where each data should be sent to for task execution. The number of entries in this array is starpu_codelet::nbuffers. This field should be used for codelets having a number of datas greater than STARPU_NMAXBUFS (see Setting The Data Handles For A Task). When defining a codelet, one should either define this field or the field starpu_codelet::nodes defined above.

starpu_codelet::model

Optional pointer to the task duration performance model associated to this codelet. This optional field is ignored when set to NULL or when its field starpu_perfmodel::symbol is not set.

starpu_codelet::power_model

Optional pointer to the task power consumption performance model associated to this codelet. This optional field is ignored when set to NULL or when its field starpu_perfmodel::field is not set. In the case of parallel codelets, this has to account for all processing units involved in the parallel execution.

starpu_codelet::per_worker_stats

Optional array for statistics collected at runtime: this is filled by StarPU and should not be accessed directly, but for example by calling the function starpu_codelet_display_stats() (See starpu_codelet_display_stats() for details).

starpu_codelet::name

Optional name of the codelet. This can be useful for debugging purposes.

struct starpu_data_descr

This type is used to describe a data handle along with an access mode.

Data Fields
starpu_data_handle_t handle describes a data
enum starpu_data_access_mode mode describes its access mode
struct starpu_task

The structure describes a task that can be offloaded on the various processing units managed by StarPU. It instantiates a codelet. It can either be allocated dynamically with the function starpu_task_create(), or declared statically. In the latter case, the programmer has to zero the structure starpu_task and to fill the different fields properly. The indicated default values correspond to the configuration of a task allocated with starpu_task_create().

Field Documentation

starpu_task::cl

Is a pointer to the corresponding structure starpu_codelet. This describes where the kernel should be executed, and supplies the appropriate implementations. When set to NULL, no code is executed during the tasks, such empty tasks can be useful for synchronization purposes.

starpu_task::buffers
Deprecated:
This field has been made deprecated. One should use instead the field starpu_task::handles to specify the data handles accessed by the task. The access modes are now defined in the field starpu_codelet::modes.
starpu_task::handles

Is an array of starpu_data_handle_t. It specifies the handles to the different pieces of data accessed by the task. The number of entries in this array must be specified in the field starpu_codelet::nbuffers, and should not exceed STARPU_NMAXBUFS. If unsufficient, this value can be set with the configure option --enable-maxbuffers.

starpu_task::interfaces

The actual data pointers to the memory node where execution will happen, managed by the DSM.

starpu_task::dyn_handles

Is an array of starpu_data_handle_t. It specifies the handles to the different pieces of data accessed by the task. The number of entries in this array must be specified in the field starpu_codelet::nbuffers. This field should be used for tasks having a number of datas greater than STARPU_NMAXBUFS (see Setting The Data Handles For A Task). When defining a task, one should either define this field or the field starpu_task::handles defined above.

starpu_task::dyn_interfaces

The actual data pointers to the memory node where execution will happen, managed by the DSM. Is used when the field starpu_task::dyn_handles is defined.

starpu_task::cl_arg

Optional pointer which is passed to the codelet through the second argument of the codelet implementation (e.g. starpu_codelet::cpu_func or starpu_codelet::cuda_func). The default value is NULL.

starpu_task::cl_arg_size

Optional field. For some specific drivers, the pointer starpu_task::cl_arg cannot not be directly given to the driver function. A buffer of size starpu_task::cl_arg_size needs to be allocated on the driver. This buffer is then filled with the starpu_task::cl_arg_size bytes starting at address starpu_task::cl_arg. In this case, the argument given to the codelet is therefore not the starpu_task::cl_arg pointer, but the address of the buffer in local store (LS) instead. This field is ignored for CPU, CUDA and OpenCL codelets, where the starpu_task::cl_arg pointer is given as such.

starpu_task::cl_arg_free

Optional field. In case starpu_task::cl_arg was allocated by the application through malloc(), setting starpu_task::cl_arg_free to 1 makes StarPU automatically call free(cl_arg) when destroying the task. This saves the user from defining a callback just for that. This is mostly useful when targetting devices where the codelet does not execute in the same memory space as the main thread.

starpu_task::callback_func

Optional field, the default value is NULL. This is a function pointer of prototype void (*f)(void *) which specifies a possible callback. If this pointer is non-null, the callback function is executed on the host after the execution of the task. Tasks which depend on it might already be executing. The callback is passed the value contained in the starpu_task::callback_arg field. No callback is executed if the field is set to NULL.

starpu_task::callback_arg

Optional field, the default value is NULL. This is the pointer passed to the callback function. This field is ignored if the field starpu_task::callback_func is set to NULL.

starpu_task::callback_arg_free

Optional field. In case starpu_task::callback_arg was allocated by the application through malloc(), setting starpu_task::callback_arg_free to 1 makes StarPU automatically call free(callback_arg) when destroying the task.

starpu_task::prologue_callback_func

Optional field, the default value is NULL. This is a function pointer of prototype void (*f)(void *) which specifies a possible callback. If this pointer is non-null, the callback function is executed on the host when the task becomes ready for execution, before getting scheduled. The callback is passed the value contained in the starpu_task::prologue_callback_arg field. No callback is executed if the field is set to NULL.

starpu_task::prologue_callback_arg

Optional field, the default value is NULL. This is the pointer passed to the prologue callback function. This field is ignored if the field starpu_task::prologue_callback_func is set to NULL.

starpu_task::prologue_callback_arg_free

Optional field. In case starpu_task::prologue_callback_arg was allocated by the application through malloc(), setting starpu_task::prologue_callback_arg_free to 1 makes StarPU automatically call free(prologue_callback_arg) when destroying the task.

starpu_task::use_tag

Optional field, the default value is 0. If set, this flag indicates that the task should be associated with the tag contained in the starpu_task::tag_id field. Tag allow the application to synchronize with the task and to express task dependencies easily.

starpu_task::tag_id

This optional field contains the tag associated to the task if the field starpu_task::use_tag is set, it is ignored otherwise.

starpu_task::sequential_consistency

If this flag is set (which is the default), sequential consistency is enforced for the data parameters of this task for which sequential consistency is enabled. Clearing this flag permits to disable sequential consistency for this task, even if data have it enabled.

starpu_task::synchronous

If this flag is set, the function starpu_task_submit() is blocking and returns only when the task has been executed (or if no worker is able to process the task). Otherwise, starpu_task_submit() returns immediately.

starpu_task::priority

Optional field, the default value is STARPU_DEFAULT_PRIO. This field indicates a level of priority for the task. This is an integer value that must be set between the return values of the function starpu_sched_get_min_priority() for the least important tasks, and that of the function starpu_sched_get_max_priority() for the most important tasks (included). The STARPU_MIN_PRIO and STARPU_MAX_PRIO macros are provided for convenience and respectively returns the value of starpu_sched_get_min_priority() and starpu_sched_get_max_priority(). Default priority is STARPU_DEFAULT_PRIO, which is always defined as 0 in order to allow static task initialization. Scheduling strategies that take priorities into account can use this parameter to take better scheduling decisions, but the scheduling policy may also ignore it.

starpu_task::execute_on_a_specific_worker

Default value is 0. If this flag is set, StarPU will bypass the scheduler and directly affect this task to the worker specified by the field starpu_task::workerid.

starpu_task::workerid

Optional field. If the field starpu_task::execute_on_a_specific_worker is set, this field indicates the identifier of the worker that should process this task (as returned by starpu_worker_get_id()). This field is ignored if the field starpu_task::execute_on_a_specific_worker is set to 0.

starpu_task::bundle

Optional field. The bundle that includes this task. If no bundle is used, this should be NULL.

starpu_task::detach

Optional field, default value is 1. If this flag is set, it is not possible to synchronize with the task by the means of starpu_task_wait() later on. Internal data structures are only guaranteed to be freed once starpu_task_wait() is called if the flag is not set.

starpu_task::destroy

Optional value. Default value is 0 for starpu_task_init(), and 1 for starpu_task_create(). If this flag is set, the task structure will automatically be freed, either after the execution of the callback if the task is detached, or during starpu_task_wait() otherwise. If this flag is not set, dynamically allocated data structures will not be freed until starpu_task_destroy() is called explicitly. Setting this flag for a statically allocated task structure will result in undefined behaviour. The flag is set to 1 when the task is created by calling starpu_task_create(). Note that starpu_task_wait_for_all() will not free any task.

starpu_task::regenerate

Optional field. If this flag is set, the task will be re-submitted to StarPU once it has been executed. This flag must not be set if the flag starpu_task::destroy is set. This flag must be set before making another task depend on this one.

starpu_task::status

Optional field. Current state of the task.

starpu_task::profiling_info

Optional field. Profiling information for the task.

starpu_task::predicted

Output field. Predicted duration of the task. This field is only set if the scheduling strategy uses performance models.

starpu_task::predicted_transfer

Optional field. Predicted data transfer duration for the task in microseconds. This field is only valid if the scheduling strategy uses performance models.

starpu_task::mf_skip

This is only used for tasks that use multiformat handle. This should only be used by StarPU.

starpu_task::prev

A pointer to the previous task. This should only be used by StarPU.

starpu_task::next

A pointer to the next task. This should only be used by StarPU.

starpu_task::starpu_private

This is private to StarPU, do not modify. If the task is allocated by hand (without starpu_task_create()), this field should be set to NULL.

starpu_task::magic

This field is set when initializing a task. The function starpu_task_submit() will fail if the field does not have the right value. This will hence avoid submitting tasks which have not been properly initialised.

starpu_task::sched_ctx

Scheduling context.

starpu_task::hypervisor_tag

Helps the hypervisor monitor the execution of this task.

starpu_task::flops

This can be set to the number of floating points operations that the task will have to achieve. This is useful for easily getting GFlops curves from the tool starpu_perfmodel_plot, and for the hypervisor load balancing.

starpu_task::scheduled

Whether the scheduler has pushed the task on some queue

Macro Definition Documentation

#define STARPU_NOWHERE

This macro is used when setting the field starpu_codelet::where to specify that the codelet has no computation part, and thus does not need to be scheduled, and data does not need to be actually loaded. This is thus essentially used for synchronization tasks.

#define STARPU_CPU

This macro is used when setting the field starpu_codelet::where to specify the codelet may be executed on a CPU processing unit.

#define STARPU_CUDA

This macro is used when setting the field starpu_codelet::where to specify the codelet may be executed on a CUDA processing unit.

#define STARPU_OPENCL

This macro is used when setting the field starpu_codelet::where to specify the codelet may be executed on a OpenCL processing unit.

#define STARPU_MULTIPLE_CPU_IMPLEMENTATIONS
Deprecated:
Setting the field starpu_codelet::cpu_func with this macro indicates the codelet will have several implementations. The use of this macro is deprecated. One should always only define the field starpu_codelet::cpu_funcs.
#define STARPU_MULTIPLE_CUDA_IMPLEMENTATIONS
Deprecated:
Setting the field starpu_codelet::cuda_func with this macro indicates the codelet will have several implementations. The use of this macro is deprecated. One should always only define the field starpu_codelet::cuda_funcs.
#define STARPU_MULTIPLE_OPENCL_IMPLEMENTATIONS
Deprecated:
Setting the field starpu_codelet::opencl_func with this macro indicates the codelet will have several implementations. The use of this macro is deprecated. One should always only define the field starpu_codelet::opencl_funcs.
#define STARPU_NMAXBUFS

Defines the maximum number of buffers that tasks will be able to take as parameters. The default value is 8, it can be changed by using the configure option --enable-maxbuffers.

#define STARPU_TASK_INITIALIZER

It is possible to initialize statically allocated tasks with this value. This is equivalent to initializing a structure starpu_task with the function starpu_task_init() function.

#define STARPU_TASK_GET_HANDLE (   task,
  i 
)

Return the i th data handle of the given task. If the task is defined with a static or dynamic number of handles, will either return the i th element of the field starpu_task::handles or the i th element of the field starpu_task::dyn_handles (see Setting The Data Handles For A Task)

#define STARPU_TASK_SET_HANDLE (   task,
  handle,
  i 
)

If the task is defined with a static or dynamic number of handles, will either set the i th element of the field starpu_task::handles or the i th element of the field starpu_task::dyn_handles (see Setting The Data Handles For A Task)

#define STARPU_CODELET_GET_MODE (   codelet,
  i 
)

Return the access mode of the i th data handle of the given codelet. If the codelet is defined with a static or dynamic number of handles, will either return the i th element of the field starpu_codelet::modes or the i th element of the field starpu_codelet::dyn_modes (see Setting The Data Handles For A Task)

#define STARPU_CODELET_SET_MODE (   codelet,
  mode,
  i 
)

Set the access mode of the i th data handle of the given codelet. If the codelet is defined with a static or dynamic number of handles, will either set the i th element of the field starpu_codelet::modes or the i th element of the field starpu_codelet::dyn_modes (see Setting The Data Handles For A Task)

Function Documentation

void starpu_codelet_init ( struct starpu_codelet *  cl)

Initialize cl with default values. Codelets should preferably be initialized statically as shown in Defining A Codelet. However such a initialisation is not always possible, e.g. when using C++.

void starpu_task_init ( struct starpu_task *  task)

Initialize task with default values. This function is implicitly called by starpu_task_create(). By default, tasks initialized with starpu_task_init() must be deinitialized explicitly with starpu_task_clean(). Tasks can also be initialized statically, using STARPU_TASK_INITIALIZER.

struct starpu_task * starpu_task_create ( void  )
read

Allocate a task structure and initialize it with default values. Tasks allocated dynamically with starpu_task_create() are automatically freed when the task is terminated. This means that the task pointer can not be used any more once the task is submitted, since it can be executed at any time (unless dependencies make it wait) and thus freed at any time. If the field starpu_task::destroy is explicitly unset, the resources used by the task have to be freed by calling starpu_task_destroy().

struct starpu_task * starpu_task_dup ( struct starpu_task *  task)
read

Allocate a task structure which is the exact duplicate of the given task.

void starpu_task_clean ( struct starpu_task *  task)

Release all the structures automatically allocated to execute task, but not the task structure itself and values set by the user remain unchanged. It is thus useful for statically allocated tasks for instance. It is also useful when users want to execute the same operation several times with as least overhead as possible. It is called automatically by starpu_task_destroy(). It has to be called only after explicitly waiting for the task or after starpu_shutdown() (waiting for the callback is not enough, since StarPU still manipulates the task after calling the callback).

void starpu_task_destroy ( struct starpu_task *  task)

Free the resource allocated during starpu_task_create() and associated with task. This function is already called automatically after the execution of a task when the field starpu_task::destroy is set, which is the default for tasks created by starpu_task_create(). Calling this function on a statically allocated task results in an undefined behaviour.

int starpu_task_wait ( struct starpu_task *  task)

This function blocks until task has been executed. It is not possible to synchronize with a task more than once. It is not possible to wait for synchronous or detached tasks. Upon successful completion, this function returns 0. Otherwise, -EINVAL indicates that the specified task was either synchronous or detached.

int starpu_task_submit ( struct starpu_task *  task)

This function submits task to StarPU. Calling this function does not mean that the task will be executed immediately as there can be data or task (tag) dependencies that are not fulfilled yet: StarPU will take care of scheduling this task with respect to such dependencies. This function returns immediately if the field starpu_task::synchronous is set to 0, and block until the termination of the task otherwise. It is also possible to synchronize the application with asynchronous tasks by the means of tags, using the function starpu_tag_wait() function for instance. In case of success, this function returns 0, a return value of -ENODEV means that there is no worker able to process this task (e.g. there is no GPU available and this task is only implemented for CUDA devices). starpu_task_submit() can be called from anywhere, including codelet functions and callbacks, provided that the field starpu_task::synchronous is set to 0.

int starpu_task_submit_to_ctx ( struct starpu_task *  task,
unsigned  sched_ctx_id 
)

This function submits a task to StarPU to the context sched_ctx_id . By default starpu_task_submit submits the task to a global context that is created automatically by StarPU.

int starpu_task_wait_for_all ( void  )

This function blocks until all the tasks that were submitted (to the current context or the global one if there aren't any) are terminated. It does not destroy these tasks.

int starpu_task_wait_for_all_in_ctx ( unsigned  sched_ctx_id)

This function waits until all the tasks that were already submitted to the context sched_ctx_id have been executed

int starpu_task_wait_for_n_submitted ( unsigned  n)

This function blocks until there are n submitted tasks left (to the current context or the global one if there aren't any) to be executed. It does not destroy these tasks.

int starpu_task_wait_for_n_submitted_in_ctx ( unsigned  sched_ctx,
unsigned  n 
)

This function waits until there are n tasks submitted left to be executed that were already submitted to the context sched_ctx_id .

int starpu_task_nready ( void  )

TODO

Return the number of submitted tasks which are ready for execution are already executing. It thus does not include tasks waiting for dependencies.

int starpu_task_nsubmitted ( void  )

Return the number of submitted tasks which have not completed yet.

struct starpu_task * starpu_task_get_current ( void  )
read

This function returns the task currently executed by the worker, or NULL if it is called either from a thread that is not a task or simply because there is no task being executed at the moment.

void starpu_codelet_display_stats ( struct starpu_codelet *  cl)

Output on stderr some statistics on the codelet cl.

int starpu_task_wait_for_no_ready ( void  )

This function waits until there is no more ready task.

void starpu_task_set_implementation ( struct starpu_task *  task,
unsigned  impl 
)

This function should be called by schedulers to specify the codelet implementation to be executed when executing the task.

unsigned starpu_task_get_implementation ( struct starpu_task *  task)

This function return the codelet implementation to be executed when executing the task.

void starpu_create_sync_task ( starpu_tag_t  sync_tag,
unsigned  ndeps,
starpu_tag_t *  deps,
void(*)(void *)  callback,
void *  callback_arg 
)

This creates (and submits) an empty task that unlocks a tag once all its dependencies are fulfilled.

Typedef Documentation

starpu_task_bundle_t

Opaque structure describing a list of tasks that should be scheduled on the same worker whenever it’s possible. It must be considered as a hint given to the scheduler as there is no guarantee that they will be executed on the same worker.

Function Documentation

void starpu_task_bundle_create ( starpu_task_bundle_t *  bundle)

Factory function creating and initializing bundle, when the call returns, memory needed is allocated and bundle is ready to use.

int starpu_task_bundle_insert ( starpu_task_bundle_t  bundle,
struct starpu_task *  task 
)

Insert task in bundle. Until task is removed from bundle its expected length and data transfer time will be considered along those of the other tasks of bundle. This function must not be called if bundle is already closed and/or task is already submitted. On success, it returns 0. There are two cases of error : if bundle is already closed it returns -EPERM, if task was already submitted it returns -EINVAL.

int starpu_task_bundle_remove ( starpu_task_bundle_t  bundle,
struct starpu_task *  task 
)

Remove task from bundle. Of course task must have been previously inserted in bundle. This function must not be called if bundle is already closed and/or task is already submitted. Doing so would result in undefined behaviour. On success, it returns 0. If bundle is already closed it returns -ENOENT.

void starpu_task_bundle_close ( starpu_task_bundle_t  bundle)

Inform the runtime that the user will not modify bundle anymore, it means no more inserting or removing task. Thus the runtime can destroy it when possible.

double starpu_task_bundle_expected_length ( starpu_task_bundle_t  bundle,
enum starpu_perfmodel_archtype  arch,

Detailed Description

Data Structure Documentation

struct starpu_perfmodel

Contains all information about a performance model. At least the type and symbol fields have to be filled when defining a performance model for a codelet. For compatibility, make sure to initialize the whole structure to zero, either by using explicit memset, or by letting the compiler implicitly do it in e.g. static storage case. If not provided, other fields have to be zero.

Field Documentation

starpu_perfmodel::type

is the type of performance model

starpu_perfmodel::cost_model
Deprecated:
This field is deprecated. Use instead the field starpu_perfmodel::cost_function field.
starpu_perfmodel::cost_function

Used by STARPU_COMMON: takes a task and implementation number, and must return a task duration estimation in micro-seconds.

starpu_perfmodel::size_base

Used by STARPU_HISTORY_BASED, STARPU_REGRESSION_BASED and STARPU_NL_REGRESSION_BASED. If not NULL, takes a task and implementation number, and returns the size to be used as index for history and regression.

starpu_perfmodel::per_arch

Used by STARPU_PER_ARCH: array of structures starpu_per_arch_perfmodel

Field Documentation

starpu_perfmodel_per_arch::cost_model
Deprecated:
This field is deprecated. Use instead the field starpu_perfmodel_per_arch::cost_function.
starpu_perfmodel_per_arch::cost_function

Used by STARPU_PER_ARCH, must point to functions which take a task, the target arch and implementation number (as mere conveniency, since the array is already indexed by these), and must return a task duration estimation in micro-seconds.

starpu_perfmodel_per_arch::size_base

Same as in structure starpu_perfmodel, but per-arch, in case it depends on the architecture-specific implementation.

starpu_perfmodel_per_arch::history

The history of performance measurements.

starpu_perfmodel_per_arch::list

Used by STARPU_HISTORY_BASED and STARPU_NL_REGRESSION_BASED, records all execution history measures.

starpu_perfmodel_per_arch::regression

Used by STARPU_REGRESSION_BASED and STARPU_NL_REGRESSION_BASED, contains the estimated factors of the regression.

Enumeration Type Documentation

enum starpu_perfmodel_archtype

Enumerates the various types of architectures.

it is possible that we have multiple versions of the same kind of workers, for instance multiple GPUs or even different CPUs within the same machine so we do not use the archtype enum type directly for performance models.

Enumerator:
STARPU_CPU_DEFAULT 

CPU combined workers between 0 and STARPU_MAXCPUS-1

STARPU_CUDA_DEFAULT 

CUDA workers

STARPU_OPENCL_DEFAULT 

OpenCL workers

enum starpu_perfmodel_type

TODO

Enumerator:
STARPU_PER_ARCH 

Application-provided per-arch cost model function

STARPU_COMMON 

Application-provided common cost model function, with per-arch factor

STARPU_HISTORY_BASED 

Automatic history-based cost model

STARPU_REGRESSION_BASED 

Automatic linear regression-based cost model (alpha * size ^ beta)

STARPU_NL_REGRESSION_BASED 

Automatic non-linear regression-based cost model (a * size ^ b + c)

Function Documentation

void starpu_perfmodel_free_sampling_directories ( void  )

this function frees internal memory used for sampling directory management. It should only be called by an application which is not calling starpu_shutdown as this function already calls it. See for example tools/starpu_perfmodel_display.c.

int starpu_perfmodel_load_symbol ( const char *  symbol,
struct starpu_perfmodel *  model 
)

loads a given performance model. The model structure has to be completely zero, and will be filled with the information saved in $STARPU_HOME/.starpu. The function is intended to be used by external tools that should read the performance model files.

int starpu_perfmodel_unload_model ( struct starpu_perfmodel *  model)

unloads the given model which has been previously loaded through the function starpu_perfmodel_load_symbol()

void starpu_perfmodel_debugfilepath ( struct starpu_perfmodel *  model,
enum starpu_perfmodel_archtype  arch,
char *  path,
size_t  maxlen,
unsigned  nimpl 
)

returns the path to the debugging information for the performance model.

void starpu_perfmodel_get_arch_name ( enum starpu_perfmodel_archtype  arch,
char *  archname,
size_t  maxlen,
unsigned  nimpl 
)

returns the architecture name for arch

enum starpu_perfmodel_archtype starpu_worker_get_perf_archtype ( int  workerid)

returns the architecture type of a given worker.

int starpu_perfmodel_list ( FILE *  output)

prints a list of all performance models on output

int starpu_perfmodel_directory ( FILE *  output)

prints the directory name storing performance models on output

void starpu_perfmodel_print ( struct starpu_perfmodel *  model,
enum starpu_perfmodel_archtype  arch,
unsigned  nimpl,
char *  parameter,
uint32_t *  footprint,
FILE *  output 
)

todo

int starpu_perfmodel_print_all ( struct starpu_perfmodel *  model,
char *  arch,
char *  parameter,
uint32_t *  footprint,
FILE *  output 
)

todo

void starpu_bus_print_bandwidth ( FILE *  f)

prints a matrix of bus bandwidths on f.

void starpu_bus_print_affinity ( FILE *  f)

prints the affinity devices on f.

void starpu_perfmodel_update_history ( struct starpu_perfmodel *  model,
struct starpu_task *  task,
enum starpu_perfmodel_archtype  arch,
unsigned  cpuid,
unsigned  nimpl,
double  measured 
)

This feeds the performance model model with an explicit measurement measured (in µs), in addition to measurements done by StarPU itself. This can be useful when the application already has an existing set of measurements done in good conditions, that StarPU could benefit from instead of doing on-line measurements. And example of use can be seen in PerformanceModelExample.

double starpu_transfer_bandwidth ( unsigned  src_node,
unsigned  dst_node 
)

Return the bandwidth of data transfer between two memory nodes

double starpu_transfer_latency ( unsigned  src_node,
unsigned  dst_node 
)

Return the latency of data transfer between two memory nodes

double starpu_transfer_predict ( unsigned  src_node,
unsigned  dst_node,
size_t  size 
)

Return the estimated time to transfer a given size between two memory nodes.

Basic Examples

Hello World Using The C Extension

This section shows how to implement a simple program that submits a task to StarPU using the StarPU C extension (C Extensions). The complete example, and additional examples, is available in the directory gcc-plugin/examples of the StarPU distribution. A similar example showing how to directly use the StarPU's API is shown in Hello World Using StarPU's API.

GCC from version 4.5 permit to use the StarPU GCC plug-in (C Extensions). This makes writing a task both simpler and less error-prone. In a nutshell, all it takes is to declare a task, declare and define its implementations (for CPU, OpenCL, and/or CUDA), and invoke the task like a regular C function. The example below defines my_task which has a single implementation for CPU:

#include <stdio.h>
/* Task declaration. */
static void my_task (int x) __attribute__ ((task));
/* Definition of the CPU implementation of `my_task'. */
static void my_task (int x)
{
printf ("Hello, world! With x = %d\n", x);
}
int main ()
{
/* Initialize StarPU. */
#pragma starpu initialize
/* Do an asynchronous call to `my_task'. */
my_task (42);
/* Wait for the call to complete. */
#pragma starpu wait
/* Terminate. */
#pragma starpu shutdown
return 0;
}

The code can then be compiled and linked with GCC and the flag -fplugin:

$ gcc `pkg-config starpu-1.1 --cflags` hello-starpu.c \
    -fplugin=`pkg-config starpu-1.1 --variable=gccplugin` \
    `pkg-config starpu-1.1 --libs`

The code can also be compiled without the StarPU C extension and will behave as a normal sequential code.

$ gcc hello-starpu.c
hello-starpu.c:33:1: warning: ‘task’ attribute directive ignored [-Wattributes]
$ ./a.out
Hello, world! With x = 42

As can be seen above, the C extensions allows programmers to use StarPU tasks by essentially annotating ``regular'' C code.

Hello World Using StarPU's API

This section shows how to achieve the same result as in the previous section using StarPU's standard C API.

Required Headers

The header starpu.h should be included in any code using StarPU.

#include <starpu.h>

Defining A Codelet

A codelet is a structure that represents a computational kernel. Such a codelet may contain an implementation of the same kernel on different architectures (e.g. CUDA, x86, ...). For compatibility, make sure that the whole structure is properly initialized to zero, either by using the function starpu_codelet_init(), or by letting the compiler implicitly do it as examplified above.

The field starpu_codelet::nbuffers specifies the number of data buffers that are manipulated by the codelet: here the codelet does not access or modify any data that is controlled by our data management library.

We create a codelet which may only be executed on the CPUs. When a CPU core will execute a codelet, it will call the function cpu_func, which must have the following prototype:

void (*cpu_func)(void *buffers[], void *cl_arg);

In this example, we can ignore the first argument of this function which gives a description of the input and output buffers (e.g. the size and the location of the matrices) since there is none. We also ignore the second argument which is a pointer to optional arguments for the codelet.

void cpu_func(void *buffers[], void *cl_arg)
{
printf("Hello world\n");
}
struct starpu_codelet cl =
{
.cpu_funcs = { cpu_func},
.nbuffers = 0
};

Submitting A Task

Before submitting any tasks to StarPU, starpu_init() must be called. The NULL argument specifies that we use the default configuration. Tasks cannot be submitted after the termination of StarPU by a call to starpu_shutdown().

In the example above, a task structure is allocated by a call to starpu_task_create(). This function only allocates and fills the corresponding structure with the default settings, but it does not submit the task to StarPU.

The field starpu_task::cl is a pointer to the codelet which the task will execute: in other words, the codelet structure describes which computational kernel should be offloaded on the different architectures, and the task structure is a wrapper containing a codelet and the piece of data on which the codelet should operate.

If the field starpu_task::synchronous is non-zero, task submission will be synchronous: the function starpu_task_submit() will not return until the task has been executed. Note that the function starpu_shutdown() does not guarantee that asynchronous tasks have been executed before it returns, starpu_task_wait_for_all() can be used to that effect, or data can be unregistered (starpu_data_unregister()), which will implicitly wait for all the tasks scheduled to work on it, unless explicitly disabled thanks to starpu_data_set_default_sequential_consistency_flag() or starpu_data_set_sequential_consistency_flag().

int main(int argc, char **argv)
{
/* initialize StarPU */
starpu_init(NULL);

Execution Of Hello World

$ make hello_world
cc $(pkg-config --cflags starpu-1.1) hello_world.c -o hello_world $(pkg-config --libs starpu-1.1)
$ ./hello_world
Hello world

Passing Arguments To The Codelet

The optional field starpu_task::cl_arg field is a pointer to a buffer (of size starpu_task::cl_arg_size) with some parameters for the kernel described by the codelet. For instance, if a codelet implements a computational kernel that multiplies its input vector by a constant, the constant could be specified by the means of this buffer, instead of registering it as a StarPU data. It must however be noted that StarPU avoids making copy whenever possible and rather passes the pointer as such, so the buffer which is pointed at must be kept allocated until the task terminates, and if several tasks are submitted with various parameters, each of them must be given a pointer to their own buffer.

struct params
{
int i;
float f;
};
void cpu_func(void *buffers[], void *cl_arg)
{
struct params *params = cl_arg;
printf("Hello world (params = {%i, %f} )\n", params->i, params->f);
}

As said before, the field starpu_codelet::nbuffers specifies the number of data buffers that are manipulated by the codelet. It does not count the argument — the parameter cl_arg of the function cpu_func — since it is not managed by our data management library, but just contains trivial parameters.

Be aware that this may be a pointer to a copy of the actual buffer, and not the pointer given by the programmer: if the codelet modifies this buffer, there is no guarantee that the initial buffer will be modified as well: this for instance implies that the buffer cannot be used as a synchronization medium. If synchronization is needed, data has to be registered to StarPU, see Vector Scaling Using StarPU's API.

int main(int argc, char **argv)
{
/* initialize StarPU */
starpu_init(NULL);
struct starpu_task *task = starpu_task_create();
task->cl = &cl; /* Pointer to the codelet defined above */
struct params params = { 1, 2.0f };
task->cl_arg = &params;
task->cl_arg_size = sizeof(params);
/* starpu_task_submit will be a blocking call */
task->synchronous = 1;
/* submit the task to StarPU */
starpu_task_submit(task);
/* terminate StarPU */
starpu_shutdown();
return 0;
}
$ make hello_world
cc $(pkg-config --cflags starpu-1.1) hello_world.c -o hello_world $(pkg-config --libs starpu-1.1)
$ ./hello_world
Hello world (params = {1, 2.000000} )

Defining A Callback

Once a task has been executed, an optional callback function starpu_task::callback_func is called when defined. While the computational kernel could be offloaded on various architectures, the callback function is always executed on a CPU. The pointer starpu_task::callback_arg is passed as an argument of the callback function. The prototype of a callback function must be:

void (*callback_function)(void *);
void callback_func(void *callback_arg)
{
printf("Callback function (arg %x)\n", callback_arg);
}
int main(int argc, char **argv)
{
/* initialize StarPU */
starpu_init(NULL);
struct starpu_task *task = starpu_task_create();
task->cl = &cl; /* Pointer to the codelet defined above */
task->callback_func = callback_func;
task->callback_arg = 0x42;
/* starpu_task_submit will be a blocking call */
task->synchronous = 1;
/* submit the task to StarPU */
starpu_task_submit(task);
/* terminate StarPU */
starpu_shutdown();
return 0;
}
$ make hello_world
cc $(pkg-config --cflags starpu-1.1) hello_world.c -o hello_world $(pkg-config --libs starpu-1.1)
$ ./hello_world
Hello world
Callback function (arg 42)

Where To Execute A Codelet

struct starpu_codelet cl =
{
.where = STARPU_CPU,
.cpu_funcs = { cpu_func},
.cpu_funcs_name = { "cpu_func"},
.nbuffers = 0
};

We create a codelet which may only be executed on the CPUs. The optional field starpu_codelet::where is a bitmask that defines where the codelet may be executed. Here, the value STARPU_CPU means that only CPUs can execute this codelet. When the optional field starpu_codelet::where is unset, its value is automatically set based on the availability of the different fields XXX_funcs.

TODO: explain starpu_codelet::cpu_funcs_name

Vector Scaling Using the C Extension

The previous example has shown how to submit tasks. In this section, we show how StarPU tasks can manipulate data.

We will first show how to use the C language extensions provided by the GCC plug-in (C Extensions). The complete example, and additional examples, is available in the directory gcc-plugin/examples of the StarPU distribution. These extensions map directly to StarPU's main concepts: tasks, task implementations for CPU, OpenCL, or CUDA, and registered data buffers. The standard C version that uses StarPU's standard C programming interface is given in Vector Scaling Using StarPU's API.

First of all, the vector-scaling task and its simple CPU implementation has to be defined:

/* Declare the `vector_scal' task. */
static void vector_scal (unsigned size, float vector[size],
float factor)
__attribute__ ((task));
/* Define the standard CPU implementation. */
static void
vector_scal (unsigned size, float vector[size], float factor)
{
unsigned i;
for (i = 0; i < size; i++)
vector[i] *= factor;
}

Next, the body of the program, which uses the task defined above, can be implemented:

int main (void)
{
#pragma starpu initialize
#define NX 0x100000
#define FACTOR 3.14
{
float vector[NX]
__attribute__ ((heap_allocated, registered));
size_t i;
for (i = 0; i < NX; i++)
vector[i] = (float) i;
vector_scal (NX, vector, FACTOR);
#pragma starpu wait
} /* VECTOR is automatically freed here. */
#pragma starpu shutdown
return valid ? EXIT_SUCCESS : EXIT_FAILURE;
}

The function main above does several things:

  • It initializes StarPU.
  • It allocates vector in the heap; it will automatically be freed when its scope is left. Alternatively, good old malloc and free could have been used, but they are more error-prone and require more typing.
  • It registers the memory pointed to by vector. Eventually, when OpenCL or CUDA task implementations are added, this will allow StarPU to transfer that memory region between GPUs and the main memory. Removing this pragma is an error.
  • It invokes the task vector_scal. The invocation looks the same as a standard C function call. However, it is an asynchronous invocation, meaning that the actual call is performed in parallel with the caller's continuation.
  • It waits for the termination of the asynchronous call vector_scal.
  • Finally, StarPU is shut down.

The program can be compiled and linked with GCC and the flag -fplugin:

$ gcc `pkg-config starpu-1.1 --cflags` vector_scal.c 
    -fplugin=`pkg-config starpu-1.1 --variable=gccplugin` 
    `pkg-config starpu-1.1 --libs`

And voilà!

Adding an OpenCL Task Implementation

Now, this is all fine and great, but you certainly want to take advantage of these newfangled GPUs that your lab just bought, don't you?

So, let's add an OpenCL implementation of the task vector_scal. We assume that the OpenCL kernel is available in a file, vector_scal_opencl_kernel.cl, not shown here. The OpenCL task implementation is similar to that used with the standard C API (Definition of the OpenCL Kernel). It is declared and defined in our C file like this:

/* The OpenCL programs, loaded from 'main' (see below). */
static struct starpu_opencl_program cl_programs;
static void vector_scal_opencl (unsigned size, float vector[size],
float factor)
__attribute__ ((task_implementation ("opencl", vector_scal)));
static void
vector_scal_opencl (unsigned size, float vector[size], float factor)
{
int id, devid, err;
cl_kernel kernel;
cl_command_queue queue;
cl_event event;
/* VECTOR is GPU memory pointer, not a main memory pointer. */
cl_mem val = (cl_mem) vector;
id = starpu_worker_get_id ();
devid = starpu_worker_get_devid (id);
/* Prepare to invoke the kernel. In the future, this will be largely automated. */
err = starpu_opencl_load_kernel (&kernel, &queue, &cl_programs,
"vector_mult_opencl", devid);
if (err != CL_SUCCESS)
STARPU_OPENCL_REPORT_ERROR (err);
err = clSetKernelArg (kernel, 0, sizeof (size), &size);
err |= clSetKernelArg (kernel, 1, sizeof (val), &val);
err |= clSetKernelArg (kernel, 2, sizeof (factor), &factor);
if (err)
STARPU_OPENCL_REPORT_ERROR (err);
size_t global = 1, local = 1;
err = clEnqueueNDRangeKernel (queue, kernel, 1, NULL, &global,
&local, 0, NULL, &event);
if (err != CL_SUCCESS)
STARPU_OPENCL_REPORT_ERROR (err);
clFinish (queue);
starpu_opencl_collect_stats (event);
clReleaseEvent (event);
/* Done with KERNEL. */
starpu_opencl_release_kernel (kernel);
}

The OpenCL kernel itself must be loaded from main, sometime after the pragma initialize:

starpu_opencl_load_opencl_from_file ("vector_scal_opencl_kernel.cl",
&cl_programs, "");

And that's it. The task vector_scal now has an additional implementation, for OpenCL, which StarPU's scheduler may choose to use at run-time. Unfortunately, the vector_scal_opencl above still has to go through the common OpenCL boilerplate; in the future, additional extensions will automate most of it.

Adding a CUDA Task Implementation

Adding a CUDA implementation of the task is very similar, except that the implementation itself is typically written in CUDA, and compiled with nvcc. Thus, the C file only needs to contain an external declaration for the task implementation:

extern void vector_scal_cuda (unsigned size, float vector[size],
float factor)
__attribute__ ((task_implementation ("cuda", vector_scal)));

The actual implementation of the CUDA task goes into a separate compilation unit, in a .cu file. It is very close to the implementation when using StarPU's standard C API (Definition of the CUDA Kernel).

/* CUDA implementation of the `vector_scal' task, to be compiled with `nvcc'. */
#include <starpu.h>
#include <stdlib.h>
static __global__ void
vector_mult_cuda (unsigned n, float *val, float factor)
{
unsigned i = blockIdx.x * blockDim.x + threadIdx.x;
if (i < n)
val[i] *= factor;
}
/* Definition of the task implementation declared in the C file. */
extern "C" void
vector_scal_cuda (size_t size, float vector[], float factor)
{
unsigned threads_per_block = 64;
unsigned nblocks = (size + threads_per_block - 1) / threads_per_block;
vector_mult_cuda <<< nblocks, threads_per_block, 0,
starpu_cuda_get_local_stream () >>> (size, vector, factor);
cudaStreamSynchronize (starpu_cuda_get_local_stream ());
}

The complete source code, in the directory gcc-plugin/examples/vector_scal of the StarPU distribution, also shows how an SSE-specialized CPU task implementation can be added.

For more details on the C extensions provided by StarPU's GCC plug-in, see C Extensions.

Vector Scaling Using StarPU's API

This section shows how to achieve the same result as explained in the previous section using StarPU's standard C API.

The full source code for this example is given in Full source code for the ’Scaling a Vector’ example.

Source Code of Vector Scaling

Programmers can describe the data layout of their application so that StarPU is responsible for enforcing data coherency and availability across the machine. Instead of handling complex (and non-portable) mechanisms to perform data movements, programmers only declare which piece of data is accessed and/or modified by a task, and StarPU makes sure that when a computational kernel starts somewhere (e.g. on a GPU), its data are available locally.

Before submitting those tasks, the programmer first needs to declare the different pieces of data to StarPU using the functions starpu_*_data_register. To ease the development of applications for StarPU, it is possible to describe multiple types of data layout. A type of data layout is called an interface. There are different predefined interfaces available in StarPU: here we will consider the vector interface.

The following lines show how to declare an array of NX elements of type float using the vector interface:

float vector[NX];
starpu_data_handle_t vector_handle;
starpu_vector_data_register(&vector_handle, 0, (uintptr_t)vector, NX,
sizeof(vector[0]));

The first argument, called the data handle, is an opaque pointer which designates the array in StarPU. This is also the structure which is used to describe which data is used by a task. The second argument is the node number where the data originally resides. Here it is 0 since the array vector is in the main memory. Then comes the pointer vector where the data can be found in main memory, the number of elements in the vector and the size of each element. The following shows how to construct a StarPU task that will manipulate the vector and a constant factor.

float factor = 3.14;
struct starpu_task *task = starpu_task_create();
task->cl = &cl; /* Pointer to the codelet defined below */
task->handles[0] = vector_handle; /* First parameter of the codelet */
task->cl_arg = &factor;
task->cl_arg_size = sizeof(factor);
task->synchronous = 1;
starpu_task_submit(task);

Since the factor is a mere constant float value parameter, it does not need a preliminary registration, and can just be passed through the pointer starpu_task::cl_arg like in the previous example. The vector parameter is described by its handle. starpu_task::handles should be set with the handles of the data, the access modes for the data are defined in the field starpu_codelet::modes (STARPU_R for read-only, STARPU_W for write-only and STARPU_RW for read and write access).

The definition of the codelet can be written as follows:

void scal_cpu_func(void *buffers[], void *cl_arg)
{
unsigned i;
float *factor = cl_arg;
/* length of the vector */
unsigned n = STARPU_VECTOR_GET_NX(buffers[0]);
/* CPU copy of the vector pointer */
float *val = (float *)STARPU_VECTOR_GET_PTR(buffers[0]);
for (i = 0; i < n; i++)
val[i] *= *factor;
}
struct starpu_codelet cl =
{
.cpu_funcs = { scal_cpu_func},
.nbuffers = 1,
.modes = { STARPU_RW }
};

The first argument is an array that gives a description of all the buffers passed in the array starpu_task::handles. The size of this array is given by the field starpu_codelet::nbuffers. For the sake of genericity, this array contains pointers to the different interfaces describing each buffer. In the case of the vector interface, the location of the vector (resp. its length) is accessible in the starpu_vector_interface::ptr (resp. starpu_vector_interface::nx) of this interface. Since the vector is accessed in a read-write fashion, any modification will automatically affect future accesses to this vector made by other tasks.

The second argument of the function scal_cpu_func contains a pointer to the parameters of the codelet (given in starpu_task::cl_arg), so that we read the constant factor from this pointer.

Execution of Vector Scaling

$ make vector_scal
cc $(pkg-config --cflags starpu-1.1) vector_scal.c -o vector_scal $(pkg-config --libs starpu-1.1)

Vector Scaling on an Hybrid CPU/GPU Machine

Contrary to the previous examples, the task submitted in this example may not only be executed by the CPUs, but also by a CUDA device.

Definition of the CUDA Kernel

The CUDA implementation can be written as follows. It needs to be compiled with a CUDA compiler such as nvcc, the NVIDIA CUDA compiler driver. It must be noted that the vector pointer returned by STARPU_VECTOR_GET_PTR is here a pointer in GPU memory, so that it can be passed as such to the kernel call vector_mult_cuda.

#include <starpu.h>
static __global__ void vector_mult_cuda(unsigned n, float *val,
float factor)
{
unsigned i = blockIdx.x*blockDim.x + threadIdx.x;
if (i < n)
val[i] *= factor;
}
extern "C" void scal_cuda_func(void *buffers[], void *_args)
{
float *factor = (float *)_args;
/* length of the vector */
unsigned n = STARPU_VECTOR_GET_NX(buffers[0]);
/* local copy of the vector pointer */
float *val = (float *)STARPU_VECTOR_GET_PTR(buffers[0]);
unsigned threads_per_block = 64;
unsigned nblocks = (n + threads_per_block-1) / threads_per_block;
vector_mult_cuda<<<nblocks,threads_per_block, 0, starpu_cuda_get_local_stream()>>>
(n, val, *factor);
cudaStreamSynchronize(starpu_cuda_get_local_stream());
}

Definition of the OpenCL Kernel

The OpenCL implementation can be written as follows. StarPU provides tools to compile a OpenCL kernel stored in a file.

__kernel void vector_mult_opencl(int nx, __global float* val, float factor)
{
const int i = get_global_id(0);
if (i < nx) {
val[i] *= factor;
}
}

Contrary to CUDA and CPU, STARPU_VECTOR_GET_DEV_HANDLE has to be used, which returns a cl_mem (which is not a device pointer, but an OpenCL handle), which can be passed as such to the OpenCL kernel. The difference is important when using partitioning, see Partitioning Data.

#include <starpu.h>
extern struct starpu_opencl_program programs;
void scal_opencl_func(void *buffers[], void *_args)
{
float *factor = _args;
int id, devid, err; /* OpenCL specific code */
cl_kernel kernel; /* OpenCL specific code */
cl_command_queue queue; /* OpenCL specific code */
cl_event event; /* OpenCL specific code */
/* length of the vector */
unsigned n = STARPU_VECTOR_GET_NX(buffers[0]);
/* OpenCL copy of the vector pointer */
cl_mem val = (cl_mem)STARPU_VECTOR_GET_DEV_HANDLE(buffers[0]);
{ /* OpenCL specific code */
id = starpu_worker_get_id();
devid = starpu_worker_get_devid(id);
err = starpu_opencl_load_kernel(&kernel, &queue,
&programs,
"vector_mult_opencl", /* Name of the codelet */
devid);
if (err != CL_SUCCESS) STARPU_OPENCL_REPORT_ERROR(err);
err = clSetKernelArg(kernel, 0, sizeof(n), &n);
err |= clSetKernelArg(kernel, 1, sizeof(val), &val);
err |= clSetKernelArg(kernel, 2, sizeof(*factor), factor);
if (err) STARPU_OPENCL_REPORT_ERROR(err);
}
{ /* OpenCL specific code */
size_t global=n;
size_t local;
size_t s;
cl_device_id device;
starpu_opencl_get_device(devid, &device);
err = clGetKernelWorkGroupInfo (kernel, device, CL_KERNEL_WORK_GROUP_SIZE,
sizeof(local), &local, &s);
if (err != CL_SUCCESS) STARPU_OPENCL_REPORT_ERROR(err);
if (local > global) local=global;
err = clEnqueueNDRangeKernel(queue, kernel, 1, NULL, &global, &local, 0,
NULL, &event);
if (err != CL_SUCCESS) STARPU_OPENCL_REPORT_ERROR(err);
}
{ /* OpenCL specific code */
clFinish(queue);
starpu_opencl_collect_stats(event);
clReleaseEvent(event);
starpu_opencl_release_kernel(kernel);
}
}

Definition of the Main Code

The CPU implementation is the same as in the previous section.

Here is the source of the main application. You can notice that the fields starpu_codelet::cuda_funcs and starpu_codelet::opencl_funcs are set to define the pointers to the CUDA and OpenCL implementations of the task.

this macro is used when calling starpu_mpi_insert_task(), and must be followed by a integer value which specified the node on which to execute the codelet.

#define STARPU_EXECUTE_ON_DATA

this macro is used when calling starpu_mpi_insert_task(), and must be followed by a data handle to specify that the node owning the given data will execute the codelet.

Function Documentation

int starpu_mpi_init ( int *  argc,
char ***  argv,
int  initialize_mpi 
)

Initializes the starpumpi library. initialize_mpi indicates if MPI should be initialized or not by StarPU. If the value is not 0, MPI will be initialized by calling MPI_Init_Thread(argc, argv, MPI_THREAD_SERIALIZED, ...).

int starpu_mpi_initialize ( void  )
Deprecated:
This function has been made deprecated. One should use instead the function starpu_mpi_init(). This function does not call MPI_Init(), it should be called beforehand.
int starpu_mpi_initialize_extended ( int *  rank,
int *  world_size 
)
Deprecated:
This function has been made deprecated. One should use instead the function starpu_mpi_init(). MPI will be initialized by starpumpi by calling MPI_Init_Thread(argc, argv, MPI_THREAD_SERIALIZED, ...).
int starpu_mpi_shutdown ( void  )

Cleans the starpumpi library. This must be called between calling starpu_mpi functions and starpu_shutdown(). MPI_Finalize() will be called if StarPU-MPI has been initialized by starpu_mpi_init().

void starpu_mpi_comm_amounts_retrieve ( size_t *  comm_amounts)

Retrieve the current amount of communications from the current node in the array comm_amounts which must have a size greater or equal to the world size. Communications statistics must be enabled (see STARPU_COMM_STATS).

int starpu_mpi_send ( starpu_data_handle_t  data_handle,
int  dest,
int  mpi_tag,
MPI_Comm  comm 
)

int *  dest,
int *  mpi_tag,
MPI_Comm *  comm,
starpu_tag_t  tag 
)

Posts array_size standard-mode, non blocking send. Each post sends the n-th data of the array data_handle to the n-th node of the array dest using the n-th message tag of the array mpi_tag within the n-th communicator of the array comm. On completion of the all the requests, tag is unlocked.

int starpu_mpi_irecv_array_detached_unlock_tag ( unsigned  array_size,
starpu_data_handle_t *  data_handle,
int *  source,
int *  mpi_tag,

void starpu_mpi_cache_flush_all_data ( MPI_Comm  comm)

Clear the send and receive communication cache for all data and invalidate their values. The function has to be called synchronously by all the MPI nodes. The function does nothing if the cache mechanism is disabled (see STARPU_MPI_CACHE).

int starpu_mpi_data_register_comm ( starpu_data_handle_t  handle,
int  tag,
int  rank,
MPI_Comm  comm 
)

Register to MPI a StarPU data handle with the given tag, rank and MPI communicator. It also automatically clears the MPI communication cache when unregistering the data.

int starpu_mpi_data_get_rank ( starpu_data_handle_t  handle)

Return the rank of the given data.

int starpu_mpi_data_get_tag ( starpu_data_handle_t  handle)

Return the tag of the given data.

int starpu_mpi_insert_task ( MPI_Comm  comm,
struct starpu_codelet *  codelet,
  ... 
)

Create and submit a task corresponding to codelet with the following arguments. The argument list must be zero-terminated.

The arguments following the codelet are the same types as for the function starpu_insert_task(). Access modes for data can also be set with STARPU_SSEND to specify the data has to be sent using a synchronous and non-blocking mode (see starpu_mpi_issend()) The extra argument STARPU_EXECUTE_ON_NODE followed by an integer allows to specify the MPI node to execute the codelet. It is also possible to specify that the node owning a specific data will execute the codelet, by using STARPU_EXECUTE_ON_DATA followed by a data handle.

The internal algorithm is as follows:

  1. Find out which MPI node is going to execute the codelet.
    • If there is only one node owning data in STARPU_W mode, it will be selected;
    • If there is several nodes owning data in STARPU_W node, the one selected will be the one having the least data in R mode so as to minimize the amount of data to be transfered;
    • The argument STARPU_EXECUTE_ON_NODE followed by an integer can be used to specify the node;
    • The argument STARPU_EXECUTE_ON_DATA followed by a data handle can be used to specify that the node owing the given data will execute the codelet.
  2. Send and receive data as requested. Nodes owning data which need to be read by the task are sending them to the MPI node which will execute it. The latter receives them.
  3. Execute the codelet. This is done by the MPI node selected in the 1st step of the algorithm.
  4. If several MPI nodes own data to be written to, send written data back to their owners.

The algorithm also includes a communication cache mechanism that allows not to send data twice to the same MPI node, unless the data has been modified. The cache can be disabled (see STARPU_MPI_CACHE).

void starpu_mpi_get_data_on_node ( MPI_Comm  comm,
starpu_data_handle_t  data_handle,
int  node 
)

Transfer data data_handle to MPI node node, sending it from its owner if needed. At least the target node and the owner have to call the function.

void starpu_mpi_get_data_on_node_detached ( MPI_Comm  comm,
starpu_data_handle_t  data_handle,
int  node,
void(*)(void *)  callback,
void *  arg 
)

Transfer data data_handle to MPI node node, sending it from its owner if needed. At least the target node and the owner have to call the function. On reception, the callback function is called with the argument arg.

void starpu_mpi_redux_data ( MPI_Comm  comm,
starpu_data_handle_t  data_handle 
)

Perform a reduction on the given data. All nodes send the data to its owner node which will perform a reduction.

int starpu_mpi_scatter_detached ( starpu_data_handle_t *  data_handles,
int  count,
int  root,
MPI_Comm  comm,
void(*)(void *)  scallback,
void *  sarg,
void(*)(void *)  rcallback,
void *  rarg 
)

Scatter data among processes of the communicator based on the ownership of the data. For each data of the array data_handles, the process root sends the data to the process owning this data. Processes receiving data must have valid data handles to receive them. On completion of the collective communication, the scallback function is called with the argument sarg on the process root, the rcallback function is called with the argument rarg on any other process.

int starpu_mpi_gather_detached ( starpu_data_handle_t *  data_handles,
int  count,
int  root,
MPI_Comm  comm,
void(*)(void *)  scallback,
void *  sarg,
void(*)(void *)  rcallback,
void *  rarg 
)

Gather data from the different processes of the communicator onto the process root. Each process owning data handle in the array data_handles will send them to the process root. The process root must have valid data handles to receive the data. On completion of the collective communication, the rcallback function is called with the argument rarg on the process root, the scallback function is called with the argument sarg on any other process.

Detailed Description

Typedef Documentation

starpu_tag_t

This type defines a task logical identifer. It is possible to associate a task with a unique tag chosen by the application, and to express dependencies between tasks by the means of those tags. To do so, fill the field starpu_task::tag_id with a tag number (can be arbitrary) and set the field starpu_task::use_tag to 1. If starpu_tag_declare_deps() is called with this tag number, the task will not be started until the tasks which holds the declared dependency tags are completed.

Function Documentation

void starpu_task_declare_deps_array ( struct starpu_task *  task,
unsigned  ndeps,
struct starpu_task *  task_array[] 
)

Declare task dependencies between a task and an array of tasks of length ndeps. This function must be called prior to the submission of the task, but it may called after the submission or the execution of the tasks in the array, provided the tasks are still valid (i.e. they were not automatically destroyed). Calling this function on a task that was already submitted or with an entry of task_array that is no longer a valid task results in an undefined behaviour. If ndeps is 0, no dependency is added. It is possible to call starpu_task_declare_deps_array() several times on the same task, in this case, the dependencies are added. It is possible to have redundancy in the task dependencies.

void starpu_tag_declare_deps ( starpu_tag_t  id,
unsigned  ndeps,
  ... 
)

Specify the dependencies of the task identified by tag id. The first argument specifies the tag which is configured, the second argument gives the number of tag(s) on which id depends. The following arguments are the tags which have to be terminated to unlock the task. This function must be called before the associated task is submitted to StarPU with starpu_task_submit().

WARNING! Use with caution. Because of the variable arity of starpu_tag_declare_deps(), note that the last arguments must be of type starpu_tag_t : constant values typically need to be explicitly casted. Otherwise, due to integer sizes and argument passing on the stack, the C compiler might consider the tag 0x200000003 instead of 0x2 and 0x3 when calling starpu_tag_declare_deps(0x1, 2, 0x2, 0x3). Using the starpu_tag_declare_deps_array() function avoids this hazard.

/* Tag 0x1 depends on tags 0x32 and 0x52 */
starpu_tag_declare_deps((starpu_tag_t)0x1, 2, (starpu_tag_t)0x32, (starpu_tag_t)0x52);
void starpu_tag_declare_deps_array ( starpu_tag_t  id,
unsigned  ndeps,
starpu_tag_t *  array 
)

This function is similar to starpu_tag_declare_deps(), except that its does not take a variable number of arguments but an array of tags of size ndeps.

/* Tag 0x1 depends on tags 0x32 and 0x52 */
starpu_tag_t tag_array[2] = {0x32, 0x52};
starpu_tag_declare_deps_array((starpu_tag_t)0x1, 2, tag_array);
int starpu_tag_wait ( starpu_tag_t  id)

This function blocks until the task associated to tag id has been executed. This is a blocking call which must therefore not be called within tasks or callbacks, but only from the application directly. It is possible to synchronize with the same tag multiple times, as long as the starpu_tag_remove() function is not called. Note that it is still possible to synchronize with a tag associated to a task for which the strucuture starpu_task was freed (e.g. if the field starpu_task::destroy was enabled).

int starpu_tag_wait_array ( unsigned  ntags,
starpu_tag_t *  id 
)

This function is similar to starpu_tag_wait() except that it blocks until all the ntags tags contained in the array id are terminated.

void starpu_tag_restart ( starpu_tag_t  id)

This function can be used to clear the already notified status of a tag which is not associated with a task. Before that, calling starpu_tag_notify_from_apps() again will not notify the successors. After that, the next call to starpu_tag_notify_from_apps() will notify the successors.

void starpu_tag_remove ( starpu_tag_t  id)

This function releases the resources associated to tag id. It can be called once the corresponding task has been executed and when there is no other tag that depend on this tag anymore.

void starpu_tag_notify_from_apps ( starpu_tag_t  id)

This function explicitly unlocks tag id. It may be useful in the case of applications which execute part of their computation outside StarPU tasks (e.g. third-party libraries). It is also provided as a convenient tool for the programmer, for instance to entirely construct the task DAG before actually giving StarPU the opportunity to execute the tasks. When called several times on the same tag, notification will be done only on first call, thus implementing "OR" dependencies, until the tag is restarted using starpu_tag_restart().

Detailed Description

Function Documentation

int starpu_combined_worker_get_size ( void  )

Return the size of the current combined worker, i.e. the total number of cpus running the same task in the case of STARPU_SPMD parallel tasks, or the total number of threads that the task is allowed to start in the case of STARPU_FORKJOIN parallel tasks.

int starpu_combined_worker_get_rank ( void  )

Return the rank of the current thread within the combined worker. Can only be used in STARPU_FORKJOIN parallel tasks, to know which part of the task to work on.

unsigned starpu_combined_worker_get_count ( void  )

Return the number of different combined workers.

int starpu_combined_worker_get_id ( void  )

Return the identifier of the current combined worker.

int starpu_combined_worker_assign_workerid ( int  nworkers,
int  workerid_array[] 
)

Register a new combined worker and get its identifier

int starpu_combined_worker_get_description ( int  workerid,
int *  worker_size,
int **  combined_workerid 
)

Get the description of a combined worker

int starpu_combined_worker_can_execute_task ( unsigned  workerid,
struct starpu_task *  task,
unsigned  nimpl 
)

Variant of starpu_worker_can_execute_task() compatible with combined workers

void starpu_parallel_task_barrier_init ( struct starpu_task *  task,
int  workerid 
)

Initialise the barrier for the parallel task, and dispatch the task between the different workers of the given combined worker.

void starpu_parallel_task_barrier_init_n ( struct starpu_task *  task,
int  worker_size 
)

Initialise the barrier for the parallel task, to be pushed to worker_size workers (without having to explicit a given combined worker).

Basic Data Management API

Data management is done at a high-level in StarPU: rather than accessing a mere list of contiguous buffers, the tasks may manipulate data that are described by a high-level construct which we call data interface.

An example of data interface is the "vector" interface which describes a contiguous data array on a spefic memory node. This interface is a simple structure containing the number of elements in the array, the size of the elements, and the address of the array in the appropriate address space (this address may be invalid if there is no valid copy of the array in the memory node). More informations on the data interfaces provided by StarPU are given in Data Interfaces.

When a piece of data managed by StarPU is used by a task, the task implementation is given a pointer to an interface describing a valid copy of the data that is accessible from the current processing unit.

Every worker is associated to a memory node which is a logical abstraction of the address space from which the processing unit gets its data. For instance, the memory node associated to the different CPU workers represents main memory (RAM), the memory node associated to a GPU is DRAM embedded on the device. Every memory node is identified by a logical index which is accessible from the function starpu_worker_get_memory_node(). When registering a piece of data to StarPU, the specified memory node indicates where the piece of data initially resides (we also call this memory node the home node of a piece of data).

Motivation

The use of specialized hardware such as accelerators or coprocessors offers an interesting approach to overcome the physical limits encountered by processor architects. As a result, many machines are now equipped with one or several accelerators (e.g. a GPU), in addition to the usual processor(s). While a lot of efforts have been devoted to offload computation onto such accelerators, very little attention as been paid to portability concerns on the one hand, and to the possibility of having heterogeneous accelerators and processors to interact on the other hand.

StarPU is a runtime system that offers support for heterogeneous multicore architectures, it not only offers a unified view of the computational resources (i.e. CPUs and accelerators at the same time), but it also takes care of efficiently mapping and executing tasks onto an heterogeneous machine while transparently handling low-level issues such as data transfers in a portable fashion.

StarPU in a Nutshell

StarPU is a software tool aiming to allow programmers to exploit the computing power of the available CPUs and GPUs, while relieving them from the need to specially adapt their programs to the target machine and processing units.

At the core of StarPU is its run-time support library, which is responsible for scheduling application-provided tasks on heterogeneous CPU/GPU machines. In addition, StarPU comes with programming language support, in the form of extensions to languages of the C family (C Extensions), as well as an OpenCL front-end (SOCL OpenCL Extensions).

StarPU's run-time and programming language extensions support a task-based programming model. Applications submit computational tasks, with CPU and/or GPU implementations, and StarPU schedules these tasks and associated data transfers on available CPUs and GPUs. The data that a task manipulates are automatically transferred among accelerators and the main memory, so that programmers are freed from the scheduling issues and technical details associated with these transfers.

StarPU takes particular care of scheduling tasks efficiently, using well-known algorithms from the literature (Task Scheduling Policy). In addition, it allows scheduling experts, such as compiler or computational library developers, to implement custom scheduling policies in a portable fashion (Defining A New Scheduling Policy).

The remainder of this section describes the main concepts used in StarPU.

Codelet and Tasks

One of the StarPU primary data structures is the codelet. A codelet describes a computational kernel that can possibly be implemented on multiple architectures such as a CPU, a CUDA device or an OpenCL device.

Another important data structure is the task. Executing a StarPU task consists in applying a codelet on a data set, on one of the architectures on which the codelet is implemented. A task thus describes the codelet that it uses, but also which data are accessed, and how they are accessed during the computation (read and/or write). StarPU tasks are asynchronous: submitting a task to StarPU is a non-blocking operation. The task structure can also specify a callback function that is called once StarPU has properly executed the task. It also contains optional fields that the application may use to give hints to the scheduler (such as priority levels).

By default, task dependencies are inferred from data dependency (sequential coherence) by StarPU. The application can however disable sequential coherency for some data, and dependencies be expressed by hand. A task may be identified by a unique 64-bit number chosen by the application which we refer as a tag. Task dependencies can be enforced by hand either by the means of callback functions, by submitting other tasks, or by expressing dependencies between tags (which can thus correspond to tasks that have not been submitted yet).

StarPU Data Management Library

Because StarPU schedules tasks at runtime, data transfers have to be done automatically and ``just-in-time'' between processing units, relieving the application programmer from explicit data transfers. Moreover, to avoid unnecessary transfers, StarPU keeps data where it was last needed, even if was modified there, and it allows multiple copies of the same data to reside at the same time on several processing units as long as it is not modified.

Application Taskification

TODO

Glossary

A codelet records pointers to various implementations of the same theoretical function.

A memory node can be either the main RAM or GPU-embedded memory.

A bus is a link between memory nodes.

A data handle keeps track of replicates of the same data (registered by the application) over various memory nodes. The data management library manages keeping them coherent.

The home memory node of a data handle is the memory node from which the data was registered (usually the main memory node).

A task represents a scheduled execution of a codelet on some data handles.

A tag is a rendez-vous point. Tasks typically have their own tag, and can depend on other tags. The value is chosen by the application.

A worker execute tasks. There is typically one per CPU computation core and one per accelerator (for which a whole CPU core is dedicated).

A driver drives a given kind of workers. There are currently CPU, CUDA, and OpenCL drivers. They usually start several workers to actually drive them.

A performance model is a (dynamic or static) model of the performance of a given codelet. Codelets can have execution time performance model as well as power consumption performance models.

A data interface describes the layout of the data: for a vector, a pointer for the start, the number of elements and the size of elements ; for a matrix, a pointer for the start, the number of elements per row, the offset between rows, and the size of each element ; etc. To access their data, codelet functions are given interfaces for the local memory node replicates of the data handles of the scheduled task.

Partitioning data means dividing the data of a given data handle (called father) into a series of children data handles which designate various portions of the former.

A filter is the function which computes children data handles from a father data handle, and thus describes how the partitioning should be done (horizontal, vertical, etc.)

Acquiring a data handle can be done from the main application, to safely access the data of a data handle from its home node, without having to unregister it.

How To Initialize A Computation Library Once For Each Worker?

Some libraries need to be initialized once for each concurrent instance that may run on the machine. For instance, a C++ computation class which is not thread-safe by itself, but for which several instanciated objects of that class can be used concurrently. This can be used in StarPU by initializing one such object per worker. For instance, the libstarpufft example does the following to be able to use FFTW on CPUs.

Some global array stores the instanciated objects:

fftw_plan plan_cpu[STARPU_NMAXWORKERS];

At initialisation time of libstarpu, the objects are initialized:

int workerid;
for (workerid = 0; workerid < starpu_worker_get_count(); workerid++) {
switch (starpu_worker_get_type(workerid)) {
case STARPU_CPU_WORKER:
plan_cpu[workerid] = fftw_plan(...);
break;
}
}

And in the codelet body, they are used:

static void fft(void *descr[], void *_args)
{
int workerid = starpu_worker_get_id();
fftw_plan plan = plan_cpu[workerid];
...
fftw_execute(plan, ...);
}

This however is not sufficient for FFT on CUDA: initialization has to be done from the workers themselves. This can be done thanks to starpu_execute_on_each_worker(). For instance libstarpufft does the following.

static void fft_plan_gpu(void *args)
{
plan plan = args;
int n2 = plan->n2[0];
int workerid = starpu_worker_get_id();
cufftPlan1d(&plan->plans[workerid].plan_cuda, n, _CUFFT_C2C, 1);
cufftSetStream(plan->plans[workerid].plan_cuda, starpu_cuda_get_local_stream());
}
void starpufft_plan(void)
{
starpu_execute_on_each_worker(fft_plan_gpu, plan, STARPU_CUDA);
}

Thread Binding on NetBSD

When using StarPU on a NetBSD machine, if the topology discovery library hwloc is used, thread binding will fail. To prevent the problem, you should at least use the version 1.7 of hwloc, and also issue the following call:

$ sysctl -w security.models.extensions.user_set_cpu_affinity=1

Or add the following line in the file /etc/sysctl.conf

security.models.extensions.user_set_cpu_affinity=1

Using StarPU With MKL 11 (Intel Composer XE 2013)

Some users had issues with MKL 11 and StarPU (versions 1.1rc1 and 1.0.5) on Linux with MKL, using 1 thread for MKL and doing all the parallelism using StarPU (no multithreaded tasks), setting the environment variable MKL_NUM_THREADS to 1, and using the threaded MKL library, with iomp5.

Using this configuration, StarPU uses only 1 core, no matter the value of STARPU_NCPU. The problem is actually a thread pinning issue with MKL.

The solution is to set the environment variable KMP_AFFINITY to disabled (http://software.intel.com/sites/products/documentation/studio/composer/en-us/2011Update/compiler_c/optaps/common/optaps_openmp_thread_affinity.htm).

Interleaving StarPU and non-StarPU code

If your application only partially uses StarPU, and you do not want to call starpu_init() / starpu_shutdown() at the beginning/end of each section, StarPU workers will poll for work between the sections. To avoid this behavior, you can "pause" StarPU with the starpu_pause() function. This will prevent the StarPU workers from accepting new work (tasks that are already in progress will not be frozen), and stop them from polling for more work.

Note that this does not prevent you from submitting new tasks, but they won't execute until starpu_resume() is called. Also note that StarPU must not be paused when you call starpu_shutdown(), and that this function pair works in a push/pull manner, ie you need to match the number of calls to these functions to clear their effect.

One way to use these functions could be:

starpu_init(NULL);
starpu_pause(); // To submit all the tasks without a single one executing
submit_some_tasks();
starpu_resume(); // The tasks start executing
starpu_task_wait_for_all();
starpu_pause(); // Stop the workers from polling
// Non-StarPU code
starpu_resume();
// ...
starpu_shutdown();

Synchronization tasks

For the application conveniency, it may be useful to define tasks which do not actually make any computation, but wear for instance dependencies between other tasks or tags, or to be submitted in callbacks, etc.

The obvious way is of course to make kernel functions empty, but such task will thus have to wait for a worker to become ready, transfer data, etc.

A much lighter way to define a synchronization task is to set its cl field to NULL. The task will thus be a mere synchronization point, without any data access or execution content: as soon as its dependencies become available, it will terminate, call the callbacks, and release dependencies.

An intermediate solution is to define a codelet with its where field set to STARPU_NOWHERE, for instance this:

struct starpu_codelet {
.where = STARPU_NOWHERE,
.nbuffers = 1,
.modes = { STARPU_R },
}
task = starpu_task_create();
task->cl = starpu_codelet;
task->handles[0] = handle;
starpu_task_submit(task);

will create a task which simply waits for the value of handle to be available for read. This task can then be depended on, etc.

Compiling OpenCL kernels

Source codes for OpenCL kernels can be stored in a file or in a string. StarPU provides functions to build the program executable for each available OpenCL device as a cl_program object. This program executable can then be loaded within a specific queue as explained in the next section. These are only helpers, Applications can also fill a starpu_opencl_program array by hand for more advanced use (e.g. different programs on the different OpenCL devices, for relocation purpose for instance).

vector interface for contiguous (non-strided) buffers

Data Fields
uintptr_t ptr local pointer of the vector
uintptr_t dev_handle device handle of the vector.
size_t offset offset in the vector
uint32_t nx number of elements on the x-axis of the vector
size_t elemsize size of the elements of the vector
struct starpu_conf

This structure is passed to the starpu_init() function in order to configure StarPU. It has to be initialized with starpu_conf_init(). When the default value is used, StarPU automatically selects the number of processing units and takes the default scheduling policy. The environment variables overwrite the equivalent parameters.

Data Fields
int magic Will be initialized by starpu_conf_init(). Should not be set by hand.
const char * sched_policy_name This is the name of the scheduling policy. This can also be specified with the environment variable STARPU_SCHED. (default = NULL).
struct starpu_sched_policy * sched_policy This is the definition of the scheduling policy. This field is ignored if starpu_conf::sched_policy_name is set. (default = NULL)
int ncpus This is the number of CPU cores that StarPU can use. This can also be specified with the environment variable STARPU_NCPU . (default = -1)
int ncuda This is the number of CUDA devices that StarPU can use. This can also be specified with the environment variable STARPU_NCUDA. (default = -1)
int nopencl This is the number of OpenCL devices that StarPU can use. This can also be specified with the environment variable STARPU_NOPENCL. (default = -1)
unsigned use_explicit_workers_bindid If this flag is set, the starpu_conf::workers_bindid array indicates where the different workers are bound, otherwise StarPU automatically selects where to bind the different workers. This can also be specified with the environment variable STARPU_WORKERS_CPUID. (default = 0)
unsigned workers_bindid If the starpu_conf::use_explicit_workers_bindid flag is set, this array indicates where to bind the different workers. The i-th entry of the starpu_conf::workers_bindid indicates the logical identifier of the processor which should execute the i-th worker. Note that the logical ordering of the CPUs is either determined by the OS, or provided by the hwloc library in case it is available.
unsigned use_explicit_workers_cuda_gpuid If this flag is set, the CUDA workers will be attached to the CUDA devices specified in the starpu_conf::workers_cuda_gpuid array. Otherwise, StarPU affects the CUDA devices in a round-robin fashion. This can also be specified with the environment variable STARPU_WORKERS_CUDAID. (default = 0)
unsigned workers_cuda_gpuid If the starpu_conf::use_explicit_workers_cuda_gpuid flag is set, this array contains the logical identifiers of the CUDA devices (as used by cudaGetDevice()).
unsigned use_explicit_workers_opencl_gpuid If this flag is set, the OpenCL workers will be attached to the OpenCL devices specified in the starpu_conf::workers_opencl_gpuid array. Otherwise, StarPU affects the OpenCL devices in a round-robin fashion. This can also be specified with the environment variable STARPU_WORKERS_OPENCLID. (default = 0)
unsigned workers_opencl_gpuid If the starpu_conf::use_explicit_workers_opencl_gpuid flag is set, this array contains the logical identifiers of the OpenCL devices to be used.
int bus_calibrate If this flag is set, StarPU will recalibrate the bus. If this value is equal to -1, the default value is used. This can also be specified with the environment variable STARPU_BUS_CALIBRATE. (default = 0)
int calibrate If this flag is set, StarPU will calibrate the performance models when executing tasks. If this value is equal to -1, the default value is used. If the value is equal to 1, it will force continuing calibration. If the value is equal to 2, the existing performance models will be overwritten. This can also be specified with the environment variable STARPU_CALIBRATE. (default = 0)
int single_combined_worker By default, StarPU executes parallel tasks concurrently. Some parallel libraries (e.g. most OpenMP implementations) however do not support concurrent calls to parallel code. In such case, setting this flag makes StarPU only start one parallel task at a time (but other CPU and GPU tasks are not affected and can be run concurrently). The parallel task scheduler will however still however still try varying combined worker sizes to look for the most efficient ones. This can also be specified with the environment variable STARPU_SINGLE_COMBINED_WORKER. (default = 0)
int disable_asynchronous_copy This flag should be set to 1 to disable asynchronous copies between CPUs and all accelerators. This can also be specified with the environment variable STARPU_DISABLE_ASYNCHRONOUS_COPY. The AMD implementation of OpenCL is known to fail when copying data asynchronously. When using this implementation, it is therefore necessary to disable asynchronous data transfers. This can also be specified at compilation time by giving to the configure script the option --disable-asynchronous-copy. (default = 0)
int disable_asynchronous_cuda_copy This flag should be set to 1 to disable asynchronous copies between CPUs and CUDA accelerators. This can also be specified with the environment variable STARPU_DISABLE_ASYNCHRONOUS_CUDA_COPY. This can also be specified at compilation time by giving to the configure script the option --disable-asynchronous-cuda-copy. (default = 0)
int disable_asynchronous_opencl_copy This flag should be set to 1 to disable asynchronous copies between CPUs and OpenCL accelerators. This can also be specified with the environment variable STARPU_DISABLE_ASYNCHRONOUS_OPENCL_COPY. The AMD implementation of OpenCL is known to fail when copying data asynchronously. When using this implementation, it is therefore necessary to disable asynchronous data transfers. This can also be specified at compilation time by giving to the configure script the option --disable-asynchronous-opencl-copy. (default = 0)
unsigned * cuda_opengl_interoperability Enable CUDA/OpenGL interoperation on these CUDA devices. This can be set to an array of CUDA device identifiers for which cudaGLSetGLDevice() should be called instead of cudaSetDevice(). Its size is specified by the starpu_conf::n_cuda_opengl_interoperability field below (default = NULL)
unsigned n_cuda_opengl_interoperability
struct starpu_driver * not_launched_drivers Array of drivers that should not be launched by StarPU. The application will run in one of its own threads. (default = NULL)
unsigned n_not_launched_drivers The number of StarPU drivers that should not be launched by StarPU. (default = 0)
unsigned trace_buffer_size Specifies the buffer size used for FxT tracing. Starting from FxT version 0.2.12, the buffer will automatically be flushed when it fills in, but it may still be interesting to specify a bigger value to avoid any flushing (which would disturb the trace).

Function Documentation

int starpu_init ( struct starpu_conf *  conf)

This is StarPU initialization method, which must be called prior to any other StarPU call. It is possible to specify StarPU’s configuration (e.g. scheduling policy, number of cores, ...) by passing a non-null argument. Default configuration is used if the passed argument is NULL. Upon successful completion, this function returns 0. Otherwise, -ENODEV indicates that no worker was available (so that StarPU was not initialized).

int starpu_conf_init ( struct starpu_conf *  conf)

This function initializes the conf structure passed as argument with the default values. In case some configuration parameters are already specified through environment variables, starpu_conf_init() initializes the fields of the structure according to the environment variables. For instance if STARPU_CALIBRATE is set, its value is put in the field starpu_conf::calibrate of the structure passed as argument. Upon successful completion, this function returns 0. Otherwise, -EINVAL indicates that the argument was NULL.

void starpu_shutdown ( void  )

This is StarPU termination method. It must be called at the end of the application: statistics and other post-mortem debugging information are not guaranteed to be available until this method has been called.

void starpu_pause ( void  )

This call is used to suspend the processing of new tasks by workers. It can be used in a program where StarPU is used during only a part of the execution. Without this call, the workers continue to poll for new tasks in a tight loop, wasting CPU time. The symmetric call to starpu_resume() should be used to unfreeze the workers.

void starpu_resume ( void  )

This is the symmetrical call to starpu_pause(), used to resume the workers polling for new tasks.

int starpu_asynchronous_copy_disabled ( void  )

Return 1 if asynchronous data transfers between CPU and accelerators are disabled.

int starpu_asynchronous_cuda_copy_disabled ( void  )

Return 1 if asynchronous data transfers between CPU and CUDA accelerators are disabled.

int starpu_asynchronous_opencl_copy_disabled ( void  )

Return 1 if asynchronous data transfers between CPU and OpenCL accelerators are disabled.

void starpu_topology_print ( FILE *  f)

Prints a description of the topology on f.

Detailed Description

Macro Definition Documentation

#define STARPU_VALUE

this macro is used when calling starpu_insert_task(), and must be followed by a pointer to a constant value and the size of the constant

#define STARPU_CALLBACK

this macro is used when calling starpu_insert_task(), and must be followed by a pointer to a callback function

#define STARPU_CALLBACK_WITH_ARG

this macro is used when calling starpu_insert_task(), and must be followed by two pointers: one to a callback function, and the other to be given as an argument to the callback function; this is equivalent to using both STARPU_CALLBACK and STARPU_CALLBACK_WITH_ARG.

#define STARPU_CALLBACK_ARG

this macro is used when calling starpu_insert_task(), and must be followed by a pointer to be given as an argument to the callback function

#define STARPU_PRIORITY

this macro is used when calling starpu_insert_task(), and must be followed by a integer defining a priority level

#define STARPU_DATA_ARRAY

TODO

#define STARPU_EXECUTE_ON_WORKER

this macro is used when calling starpu_task_insert(), and must be followed by an integer value specifying the worker on which to execute the task (as specified by starpu_task::execute_on_a_specific_worker)

#define STARPU_TAG

this macro is used when calling starpu_insert_task(), and must be followed by a tag.

#define STARPU_FLOPS

this macro is used when calling starpu_insert_task(), and must be followed by an amount of floating point operations, as a double. Users MUST explicitly cast into double, otherwise parameter passing will not work.

#define STARPU_SCHED_CTX

this macro is used when calling starpu_insert_task(), and must be followed by the id of the scheduling context to which we want to submit the task.

Function Documentation

int starpu_insert_task ( struct starpu_codelet *  cl,
  ... 
)

Create and submit a task corresponding to cl with the following arguments. The argument list must be zero-terminated.

The arguments following the codelet can be of the following types:

When using STARPU_DATA_ARRAY, the access mode of the data handles is not defined, it will be taken from the codelet starpu_codelet::modes or starpu_codelet::dyn_modes field.

Parameters to be passed to the codelet implementation are defined through the type STARPU_VALUE. The function starpu_codelet_unpack_args() must be called within the codelet implementation to retrieve them.

void starpu_codelet_pack_args ( void **  arg_buffer,
size_t *  arg_buffer_size,
  ... 
)

Pack arguments of type STARPU_VALUE into a buffer which can be given to a codelet and later unpacked with the function starpu_codelet_unpack_args().

void starpu_codelet_unpack_args ( void *  cl_arg,
  ... 
)

Retrieve the arguments of type STARPU_VALUE associated to a task automatically created using the function starpu_insert_task().

struct starpu_task * starpu_task_build ( struct starpu_codelet *  cl,
  ... 
)
read

Create a task corresponding to cl with the following arguments. The argument list must be zero-terminated. The arguments following the codelet are the same as the ones for the function starpu_insert_task().

MPI Support

The integration of MPI transfers within task parallelism is done in a very natural way by the means of asynchronous interactions between the application and StarPU. This is implemented in a separate libstarpumpi library which basically provides "StarPU" equivalents of MPI_* functions, where void * buffers are replaced with starpu_data_handle_t, and all GPU-RAM-NIC transfers are handled efficiently by StarPU-MPI. The user has to use the usual mpirun command of the MPI implementation to start StarPU on the different MPI nodes.

An MPI Insert Task function provides an even more seamless transition to a distributed application, by automatically issuing all required data transfers according to the task graph and an application-provided distribution.

Simple Example

The flags required to compile or link against the MPI layer are accessible with the following commands:

$ pkg-config --cflags starpumpi-1.1  # options for the compiler
$ pkg-config --libs starpumpi-1.1    # options for the linker

You also need pass the option –static if the application is to be linked statically.

Point To Point Communication

The standard point to point communications of MPI have been implemented. The semantic is similar to the MPI one, but adapted to the DSM provided by StarPU. A MPI request will only be submitted when the data is available in the main memory of the node submitting the request.

There is two types of asynchronous communications: the classic asynchronous communications and the detached communications. The classic asynchronous communications (starpu_mpi_isend() and starpu_mpi_irecv()) need to be followed by a call to starpu_mpi_wait() or to starpu_mpi_test() to wait for or to test the completion of the communication. Waiting for or testing the completion of detached communications is not possible, this is done internally by StarPU-MPI, on completion, the resources are automatically released. This mechanism is similar to the pthread detach state attribute which determines whether a thread will be created in a joinable or a detached state.

For any communication, the call of the function will result in the creation of a StarPU-MPI request, the function starpu_data_acquire_cb() is then called to asynchronously request StarPU to fetch the data in main memory; when the data is available in main memory, a StarPU-MPI function is called to put the new request in the list of the ready requests.

The StarPU-MPI progression thread regularly polls this list of ready requests. For each new ready request, the appropriate function is called to post the corresponding MPI call. For example, calling starpu_mpi_isend() will result in posting MPI_Isend. If the request is marked as detached, the request will be put in the list of detached requests.

The StarPU-MPI progression thread also polls the list of detached requests. For each detached request, it regularly tests the completion of the MPI request by calling MPI_Test. On completion, the data handle is released, and if a callback was defined, it is called.

Communication gives the list of all the point to point communications defined in StarPU-MPI.

Exchanging User Defined Data Interface

New data interfaces defined as explained in Defining A New Data Interface can also be used within StarPU-MPI and exchanged between nodes. Two functions needs to be defined through the type starpu_data_interface_ops. The function starpu_data_interface_ops::pack_data takes a handle and returns a contiguous memory buffer along with its size where data to be conveyed to another node should be copied. The reversed operation is implemented in the function starpu_data_interface_ops::unpack_data which takes a contiguous memory buffer and recreates the data handle.

static int complex_pack_data(starpu_data_handle_t handle, unsigned node, void **ptr, starpu_ssize_t *count)
{
STARPU_ASSERT(starpu_data_test_if_allocated_on_node(handle, node));
struct starpu_complex_interface *complex_interface =
(struct starpu_complex_interface *) starpu_data_get_interface_on_node(handle, node);
*count = complex_get_size(handle);
*ptr = malloc(*count);
memcpy(*ptr, complex_interface->real, complex_interface->nx*sizeof(double));
memcpy(*ptr+complex_interface->nx*sizeof(double), complex_interface->imaginary,
complex_interface->nx*sizeof(double));
return 0;
}
static int complex_unpack_data(starpu_data_handle_t handle, unsigned node, void *ptr, size_t count)
{
STARPU_ASSERT(starpu_data_test_if_allocated_on_node(handle, node));
struct starpu_complex_interface *complex_interface =
(struct starpu_complex_interface *) starpu_data_get_interface_on_node(handle, node);
memcpy(complex_interface->real, ptr, complex_interface->nx*sizeof(double));
memcpy(complex_interface->imaginary, ptr+complex_interface->nx*sizeof(double),
complex_interface->nx*sizeof(double));
return 0;
}
static struct starpu_data_interface_ops interface_complex_ops =
{
...
.pack_data = complex_pack_data,
.unpack_data = complex_unpack_data
};

MPI Insert Task Utility

To save the programmer from having to explicit all communications, StarPU provides an "MPI Insert Task Utility". The principe is that the application decides a distribution of the data over the MPI nodes by allocating it and notifying StarPU of that decision, i.e. tell StarPU which MPI node "owns" which data. It also decides, for each handle, an MPI tag which will be used to exchange the content of the handle. All MPI nodes then process the whole task graph, and StarPU automatically determines which node actually execute which task, and trigger the required MPI transfers.

The list of functions is described in MPI Insert Task.

Here an stencil example showing how to use starpu_mpi_insert_task(). One first needs to define a distribution function which specifies the locality of the data. Note that the data needs to be registered to MPI by calling starpu_mpi_data_register(). This function allows to set the distribution information and the MPI tag which should be used when communicating the data. It also allows to automatically clear the MPI communication cache when unregistering the data.

/* Returns the MPI node number where data is */
int my_distrib(int x, int y, int nb_nodes) {
/* Block distrib */
return ((int)(x / sqrt(nb_nodes) + (y / sqrt(nb_nodes)) * sqrt(nb_nodes))) % nb_nodes;
// /* Other examples useful for other kinds of computations */
// /* / distrib */
// return (x+y) % nb_nodes;
// /* Block cyclic distrib */
// unsigned side = sqrt(nb_nodes);
// return x % side + (y % side) * size;
}

Now the data can be registered within StarPU. Data which are not owned but will be needed for computations can be registered through the lazy allocation mechanism, i.e. with a home_node set to -1. StarPU will automatically allocate the memory when it is used for the first time.

One can note an optimization here (the else if test): we only register data which will be needed by the tasks that we will execute.

unsigned matrix[X][Y];
starpu_data_handle_t data_handles[X][Y];
for(x = 0; x < X; x++) {
for (y = 0; y < Y; y++) {
int mpi_rank = my_distrib(x, y, size);
if (mpi_rank == my_rank)
/* Owning data */
starpu_variable_data_register(&data_handles[x][y], 0,
(uintptr_t)&(matrix[x][y]), sizeof(unsigned));
else if (my_rank == my_distrib(x+1, y, size) || my_rank == my_distrib(x-1, y, size)
|| my_rank == my_distrib(x, y+1, size) || my_rank == my_distrib(x, y-1, size))
/* I don't own that index, but will need it for my computations */
starpu_variable_data_register(&data_handles[x][y], -1,
(uintptr_t)NULL, sizeof(unsigned));
else
/* I know it's useless to allocate anything for this */
data_handles[x][y] = NULL;
if (data_handles[x][y]) {
starpu_mpi_data_register(data_handles[x][y], x*X+y, mpi_rank);
}
}
}

Now starpu_mpi_insert_task() can be called for the different steps of the application.

for(loop=0 ; loop<niter; loop++)
for (x = 1; x < X-1; x++)
for (y = 1; y < Y-1; y++)
starpu_mpi_insert_task(MPI_COMM_WORLD, &stencil5_cl,
STARPU_RW, data_handles[x][y],
STARPU_R, data_handles[x-1][y],
STARPU_R, data_handles[x+1][y],
STARPU_R, data_handles[x][y-1],
STARPU_R, data_handles[x][y+1],
0);
starpu_task_wait_for_all();

I.e. all MPI nodes process the whole task graph, but as mentioned above, for each task, only the MPI node which owns the data being written to (here, data_handles[x][y]) will actually run the task. The other MPI nodes will automatically send the required data.

This can be a concern with a growing number of nodes. To avoid this, the application can prune the task for loops according to the data distribution, so as to only submit tasks on nodes which have to care about them (either to execute them, or to send the required data).

A way to do some of this quite easily can be to just add an if like this:

for(loop=0 ; loop<niter; loop++)
for (x = 1; x < X-1; x++)
for (y = 1; y < Y-1; y++)
if (my_distrib(x,y,size) == my_rank
|| my_distrib(x-1,y,size) == my_rank
|| my_distrib(x+1,y,size) == my_rank
|| my_distrib(x,y-1,size) == my_rank
|| my_distrib(x,y+1,size) == my_rank)
starpu_mpi_insert_task(MPI_COMM_WORLD, &stencil5_cl,
STARPU_RW, data_handles[x][y],
STARPU_R, data_handles[x-1][y],
STARPU_R, data_handles[x+1][y],
STARPU_R, data_handles[x][y-1],
STARPU_R, data_handles[x][y+1],
0);
starpu_task_wait_for_all();

This permits to drop the cost of function call argument passing and parsing.

If the my_distrib function can be inlined by the compiler, the latter can improve the test.

If the size can be made a compile-time constant, the compiler can considerably improve the test further.

If the distribution function is not too complex and the compiler is very good, the latter can even optimize the for loops, thus dramatically reducing the cost of task submission.

MPI cache support

StarPU-MPI automatically optimizes duplicate data transmissions: if an MPI node B needs a piece of data D from MPI node A for several tasks, only one transmission of D will take place from A to B, and the value of D will be kept on B as long as no task modifies D.

If a task modifies D, B will wait for all tasks which need the previous value of D, before invalidating the value of D. As a consequence, it releases the memory occupied by D. Whenever a task running on B needs the new value of D, allocation will take place again to receive it.

Since tasks can be submitted dynamically, StarPU-MPI can not know whether the current value of data D will again be used by a newly-submitted task before being modified by another newly-submitted task, so until a task is submitted to modify the current value, it can not decide by itself whether to flush the cache or not. The application can however explicitly tell StarPU-MPI to flush the cache by calling starpu_mpi_cache_flush() or starpu_mpi_cache_flush_all_data(), for instance in case the data will not be used at all any more (see for instance the cholesky example in mpi/examples/matrix_decomposition), or at least not in the close future. If a newly-submitted task actually needs the value again, another transmission of D will be initiated from A to B.

The whole caching behavior can be disabled thanks to the ::STARPU_MPI_CACHE environment variable. The variable ::STARPU_MPI_CACHE_STATS can be set to 1 to enable the runtime to display messages when data are added or removed from the cache holding the received data.

MPI Data migration

The application can dynamically change its mind about the data distribution, to balance the load over MPI nodes for instance. This can be done very simply by requesting an explicit move and then change the registered rank. For instance, we here switch to a new distribution function my_distrib2: we first register any data that wasn't registered already and will be needed, then migrate the data, and register the new location.

for(x = 0; x < X; x++) {
for (y = 0; y < Y; y++) {
int mpi_rank = my_distrib2(x, y, size);
if (!data_handles[x][y] && (mpi_rank == my_rank
|| my_rank == my_distrib(x+1, y, size) || my_rank == my_distrib(x-1, y, size)
|| my_rank == my_distrib(x, y+1, size) || my_rank == my_distrib(x, y-1, size)))
/* Register newly-needed data */
starpu_variable_data_register(&data_handles[x][y], -1,
(uintptr_t)NULL, sizeof(unsigned));
if (data_handles[x][y]) {
/* Migrate the data */
starpu_mpi_get_data_on_node_detached(MPI_COMM_WORLD, data_handles[x][y], mpi_rank, NULL, NULL);
/* And register the new rank of the matrix */
starpu_mpi_data_set_rank(data_handles[x][y], mpi_rank);
}
}
}

From then on, further tasks submissions will use the new data distribution, which will thus change both MPI communications and task assignments.

Very importantly, since all nodes have to agree on which node owns which data so as to determine MPI communications and task assignments the same way, all nodes have to perform the same data migration, and at the same point among task submissions. It thus does not require a strict synchronization, just a clear separation of task submissions before and after the data redistribution.

Before data unregistration, it has to be migrated back to its original home node (the value, at least), since that is where the user-provided buffer resides. Otherwise the unregistration will complain that it does not have the latest value on the original home node.

for(x = 0; x < X; x++) {
for (y = 0; y < Y; y++) {
if (data_handles[x][y]) {
int mpi_rank = my_distrib(x, y, size);
/* Get back data to original place where the user-provided buffer is. */
starpu_mpi_get_data_on_node_detached(MPI_COMM_WORLD, data_handles[x][y], mpi_rank, NULL, NULL);
/* And unregister it */
starpu_data_unregister(data_handles[x][y]);
}
}
}

StarPU Handbook
SOCL OpenCL Extensions

SOCL is an OpenCL implementation based on StarPU. It gives a unified access to every available OpenCL device: applications can now share entities such as Events, Contexts or Command Queues between several OpenCL implementations.

In addition, command queues that are created without specifying a device provide automatic scheduling of the submitted commands on OpenCL devices contained in the context to which the command queue is attached.

Note: this is still an area under development and subject to change.

When compiling StarPU, SOCL will be enabled if a valid OpenCL implementation is found on your system. To be able to run the SOCL test suite, the environment variable SOCL_OCL_LIB_OPENCL needs to be defined to the location of the file libOpenCL.so of the OCL ICD implementation. You should for example add the following line in your file .bashrc

export SOCL_OCL_LIB_OPENCL=/usr/lib/x86_64-linux-gnu/libOpenCL.so

You can then run the test suite in the directory socl/examples.

$ make check
...
PASS: basic/basic
PASS: testmap/testmap
PASS: clinfo/clinfo
PASS: matmul/matmul
PASS: mansched/mansched
==================
All 5 tests passed
==================

The environment variable OCL_ICD_VENDORS has to point to the directory where the ICD files are installed. When compiling StarPU, the files are in the directory socl/vendors. With an installed version of StarPU, the files are installed in the directory $prefix/share/starpu/opencl/vendors.

To run the tests by hand, you have to call for example,

$ LD_PRELOAD=$SOCL_OCL_LIB_OPENCL OCL_ICD_VENDORS=socl/vendors/ socl/examples/clinfo/clinfo
Number of platforms:	2
  Plaform Profile:	FULL_PROFILE
  Plaform Version:	OpenCL 1.1 CUDA 4.2.1

  Plaform Vendor:	NVIDIA Corporation
  Plaform Extensions:	cl_khr_byte_addressable_store cl_khr_icd cl_khr_gl_sharing cl_nv_compiler_options cl_nv_device_attribute_query cl_nv_pragma_unroll

  Plaform Name:		SOCL Platform

  Plaform Extensions:	cl_khr_icd
....
$

To enable the use of CPU cores via OpenCL, one can set the STARPU_OPENCL_ON_CPUS environment variable to 1 and STARPU_NCPUS to 0 (to avoid using CPUs both via the OpenCL driver and the normal CPU driver).

Detailed Description

Macro Definition Documentation

#define SC_HYPERVISOR_MAX_IDLE

This macro is used when calling sc_hypervisor_ctl() and must be followed by 3 arguments: an array of int for the workerids to apply the condition, an int to indicate the size of the array, and a double value indicating the maximum idle time allowed for a worker before the resizing process should be triggered

#define SC_HYPERVISOR_PRIORITY

This macro is used when calling sc_hypervisor_ctl() and must be followed by 3 arguments: an array of int for the workerids to apply the condition, an int to indicate the size of the array, and an int value indicating the priority of the workers previously mentioned. The workers with the smallest priority are moved the first.

#define SC_HYPERVISOR_MIN_WORKERS

This macro is used when calling sc_hypervisor_ctl() and must be followed by 1 argument(int) indicating the minimum number of workers a context should have, underneath this limit the context cannot execute.

#define SC_HYPERVISOR_MAX_WORKERS

This macro is used when calling sc_hypervisor_ctl() and must be followed by 1 argument(int) indicating the maximum number of workers a context should have, above this limit the context would not be able to scale

#define SC_HYPERVISOR_GRANULARITY

This macro is used when calling sc_hypervisor_ctl() and must be followed by 1 argument(int) indicating the granularity of the resizing process (the number of workers should be moved from the context once it is resized) This parameter is ignore for the Gflops rate based strategy (see Resizing Strategies), the number of workers that have to be moved is calculated by the strategy.

Function Documentation

void * sc_hypervisor_init ( struct sc_hypervisor_policy *  policy)

There is a single hypervisor that is in charge of resizing contexts and the resizing strategy is chosen at the initialization of the hypervisor. A single resize can be done at a time.

The Scheduling Context Hypervisor Plugin provides a series of performance counters to StarPU. By incrementing them, StarPU can help the hypervisor in the resizing decision making process.

This function initializes the hypervisor to use the strategy provided as parameter and creates the performance counters (see starpu_sched_ctx_performance_counters). These performance counters represent actually some callbacks that will be used by the contexts to notify the information needed by the hypervisor.

Note: The Hypervisor is actually a worker that takes this role once certain conditions trigger the resizing process (there is no additional thread assigned to the hypervisor).

void sc_hypervisor_shutdown ( void  )

The hypervisor and all information concerning it is cleaned. There is no synchronization between this function and starpu_shutdown(). Thus, this should be called after starpu_shutdown(), because the performance counters will still need allocated callback functions.

void sc_hypervisor_register_ctx ( unsigned  sched_ctx,
double  total_flops 
)

Scheduling Contexts that have to be resized by the hypervisor must be first registered to the hypervisor. This function registers the context to the hypervisor, and indicate the number of flops the context will execute (used for Gflops rate based strategy or any other custom strategy needing it, for the others we can pass 0.0)

void sc_hypervisor_unregister_ctx ( unsigned  sched_ctx)

Whenever we want to exclude contexts from the resizing process we have to unregister them from the hypervisor.

void sc_hypervisor_stop_resize ( unsigned  sched_ctx)

The user can totally forbid the resizing of a certain context or can then change his mind and allow it (in this case the resizing is managed by the hypervisor, that can forbid it or allow it)

void sc_hypervisor_start_resize ( unsigned  sched_ctx)

Allow resizing of a context. The user can then provide information to the hypervisor concerning the conditions of resizing.

char * sc_hypervisor_get_policy ( )

Returns the name of the resizing policy the hypervisor uses

void sc_hypervisor_add_workers_to_sched_ctx ( int *  workers_to_add,
unsigned  nworkers_to_add,
unsigned  sched_ctx 
)

Ask the hypervisor to add workers to a sched_ctx

void sc_hypervisor_remove_workers_from_sched_ctx ( int *  workers_to_remove,
unsigned  nworkers_to_remove,
unsigned  sched_ctx,
unsigned  now 
)

Ask the hypervisor to remove workers from a sched_ctx

void sc_hypervisor_move_workers ( unsigned  sender_sched_ctx,
unsigned  receiver_sched_ctx,
int *  workers_to_move,
unsigned  nworkers_to_move,
unsigned  now 
)

Moves workers from one context to another

void sc_hypervisor_size_ctxs ( unsigned *  sched_ctxs,
int  nsched_ctxs,
int *  workers,
int  nworkers 
)

Ask the hypervisor to chose a distribution of workers in the required contexts

void sc_hypervisor_set_type_of_task ( struct starpu_codelet *  cl,
unsigned  sched_ctx,
uint32_t  footprint,
size_t  data_size 
)

Indicate the types of tasks a context will execute in order to better decide the sizing of ctxs

void sc_hypervisor_update_diff_total_flops ( unsigned  sched_ctx,
double  diff_total_flops 
)

Change dynamically the total number of flops of a context, move the deadline of the finishing time of the context

void sc_hypervisor_update_diff_elapsed_flops ( unsigned  sched_ctx,
double  diff_task_flops 
)

Change dynamically the number of the elapsed flops in a context, modify the past in order to better compute the speed

void sc_hypervisor_ctl ( unsigned  sched_ctx,
  ... 
)

Inputs conditions to the context sched_ctx with the following arguments. The argument list must be zero-terminated.

How To Optimize Performance With StarPU

TODO: improve!

Simply encapsulating application kernels into tasks already permits to seamlessly support CPU and GPUs at the same time. To achieve good performance, a few additional changes are needed.

Data Management

When the application allocates data, whenever possible it should use the starpu_malloc() function, which will ask CUDA or OpenCL to make the allocation itself and pin the corresponding allocated memory, or to use the starpu_memory_pin() function to pin memory allocated by other ways, such as local arrays. This is needed to permit asynchronous data transfer, i.e. permit data transfer to overlap with computations. Otherwise, the trace will show that the DriverCopyAsync state takes a lot of time, this is because CUDA or OpenCL then reverts to synchronous transfers.

By default, StarPU leaves replicates of data wherever they were used, in case they will be re-used by other tasks, thus saving the data transfer time. When some task modifies some data, all the other replicates are invalidated, and only the processing unit which ran that task will have a valid replicate of the data. If the application knows that this data will not be re-used by further tasks, it should advise StarPU to immediately replicate it to a desired list of memory nodes (given through a bitmask). This can be understood like the write-through mode of CPU caches.

starpu_data_set_wt_mask(img_handle, 1<<0);

will for instance request to always automatically transfer a replicate into the main memory (node 0), as bit 0 of the write-through bitmask is being set.

starpu_data_set_wt_mask(img_handle, ~0U);

will request to always automatically broadcast the updated data to all memory nodes.

Setting the write-through mask to ~0U can also be useful to make sure all memory nodes always have a copy of the data, so that it is never evicted when memory gets scarse.

Implicit data dependency computation can become expensive if a lot of tasks access the same piece of data. If no dependency is required on some piece of data (e.g. because it is only accessed in read-only mode, or because write accesses are actually commutative), use the function starpu_data_set_sequential_consistency_flag() to disable implicit dependencies on that data.

In the same vein, accumulation of results in the same data can become a bottleneck. The use of the mode STARPU_REDUX permits to optimize such accumulation (see Data Reduction).

Applications often need a data just for temporary results. In such a case, registration can be made without an initial value, for instance this produces a vector data:

starpu_vector_data_register(&handle, -1, 0, n, sizeof(float));

StarPU will then allocate the actual buffer only when it is actually needed, e.g. directly on the GPU without allocating in main memory.

In the same vein, once the temporary results are not useful any more, the data should be thrown away. If the handle is not to be reused, it can be unregistered:

starpu_data_unregister_submit(handle);

actual unregistration will be done after all tasks working on the handle terminate.

If the handle is to be reused, instead of unregistering it, it can simply be invalidated:

starpu_data_invalidate_submit(handle);

the buffers containing the current value will then be freed, and reallocated only when another task writes some value to the handle.

Task Granularity

Like any other runtime, StarPU has some overhead to manage tasks. Since it does smart scheduling and data management, that overhead is not always neglectable. The order of magnitude of the overhead is typically a couple of microseconds, which is actually quite smaller than the CUDA overhead itself. The amount of work that a task should do should thus be somewhat bigger, to make sure that the overhead becomes neglectible. The offline performance feedback can provide a measure of task length, which should thus be checked if bad performance are observed. To get a grasp at the scalability possibility according to task size, one can run tests/microbenchs/tasks_size_overhead.sh which draws curves of the speedup of independent tasks of very small sizes.

The choice of scheduler also has impact over the overhead: for instance, the scheduler dmda takes time to make a decision, while eager does not. tasks_size_overhead.sh can again be used to get a grasp at how much impact that has on the target machine.

Task Submission

To let StarPU make online optimizations, tasks should be submitted asynchronously as much as possible. Ideally, all the tasks should be submitted, and mere calls to starpu_task_wait_for_all() or starpu_data_unregister() be done to wait for termination. StarPU will then be able to rework the whole schedule, overlap computation with communication, manage accelerator local memory usage, etc.

Task Priorities

By default, StarPU will consider the tasks in the order they are submitted by the application. If the application programmer knows that some tasks should be performed in priority (for instance because their output is needed by many other tasks and may thus be a bottleneck if not executed early enough), the field starpu_task::priority should be set to transmit the priority information to StarPU.

Task Scheduling Policy

The basics of the scheduling policy are that

  • The scheduler gets to schedule tasks (push operation) when they become ready to be executed, i.e. they are not waiting for some tags, data dependencies or task dependencies.
  • Workers pull tasks (pop operation) one by one from the scheduler.

This means scheduling policies usually contain at least one queue of tasks to store them between the time when they become available, and the time when a worker gets to grab them.

By default, StarPU uses the simple greedy scheduler eager. This is because it provides correct load balance even if the application codelets do not have performance models. If your application codelets have performance models (PerformanceModelExample), you should change the scheduler thanks to the environment variable STARPU_SCHED. For instance export STARPU_SCHED=dmda . Use help to get the list of available schedulers.

The eager scheduler uses a central task queue, from which all workers draw tasks to work on concurrently. This however does not permit to prefetch data since the scheduling decision is taken late. If a task has a non-0 priority, it is put at the front of the queue.

The prio scheduler also uses a central task queue, but sorts tasks by priority (between -5 and 5).

The random scheduler uses a queue per worker, and distributes tasks randomly according to assumed worker overall performance.

The ws (work stealing) scheduler uses a queue per worker, and schedules a task on the worker which released it by default. When a worker becomes idle, it steals a task from the most loaded worker.

The dm (deque model) scheduler uses task execution performance models into account to perform a HEFT-similar scheduling strategy: it schedules tasks where their termination time will be minimal. The difference with HEFT is that dm schedules tasks as soon as they become available, and thus in the order they become available, without taking priorities into account.

The dmda (deque model data aware) scheduler is similar to dm, but it also takes into account data transfer time.

The dmdar (deque model data aware ready) scheduler is similar to dmda, but it also sorts tasks on per-worker queues by number of already-available data buffers on the target device.

The dmdas (deque model data aware sorted) scheduler is similar to dmdar, except that it sorts tasks by priority order, which allows to become even closer to HEFT by respecting priorities after having made the scheduling decision (but it still schedules tasks in the order they become available).

The heft (heterogeneous earliest finish time) scheduler is a deprecated alias for dmda.

The pheft (parallel HEFT) scheduler is similar to dmda, it also supports parallel tasks (still experimental). Should not be used when several contexts using it are being executed simultaneously.

The peager (parallel eager) scheduler is similar to eager, it also supports parallel tasks (still experimental). Should not be used when several contexts using it are being executed simultaneously.

How to limit memory per node

By default, StarPU makes sure to use at most 90% of the memory of GPU devices, moving data in and out of the device as appropriate and with prefetch and writeback optimizations. Concerning the main memory, by default it will not limit its consumption, since by default it has nowhere to push the data to when memory gets tight. This also means that by default StarPU will not cache buffer allocations in main memory, since it does not know how much of the system memory it can afford.

In the case of GPUs, the STARPU_LIMIT_CUDA_MEM, STARPU_LIMIT_CUDA_devid_MEM, STARPU_LIMIT_OPENCL_MEM, and STARPU_LIMIT_OPENCL_devid_MEM environment variables can be used to control how much (in MiB) of the GPU device memory should be used at most by StarPU (their default values are 90% of the available memory).

In the case of the main memory, the STARPU_LIMIT_CPU_MEM environment variable can be used to specify how much (in MiB) of the main memory should be used at most by StarPU for buffer allocations. This way, StarPU will be able to cache buffer allocations (which can be a real benefit if a lot of bufferes are involved, or if allocation fragmentation can become a problem).

It should be noted that by default only buffer allocations automatically done by StarPU are accounted here, i.e. allocations performed through starpu_malloc_on_node() which are used by the data interfaces (matrix, vector, etc.). This does not include allocations performed by the application through e.g. malloc(). It does not include allocations performed through starpu_malloc() either, only allocations performed explicitly with the STARPU_MALLOC_COUNT flag (i.e. through starpu_malloc_flags(STARPU_MALLOC_COUNT)) are taken into account.

starpu_memory_get_total and starpu_memory_get_available can be used to get an estimation of how much memory is available. starpu_memory_wait_available can also be used to block until an amount of memory becomes available.

How To Reduce The Memory Footprint Of Internal Data Structures

It is possible to reduce the memory footprint of the task and data internal structures of StarPU by describing the shape of your machine and/or your application at the configure step.

To reduce the memory footprint of the data internal structures of StarPU, one can set the --enable-maxcpus, --enable-maxcudadev, --enable-maxopencldev and --enable-maxnodes configure parameters to give StarPU the architecture of the machine it will run on, thus tuning the size of the structures to the machine.

To reduce the memory footprint of the task internal structures of StarPU, one can set the --enable-maxbuffers configure parameter to give StarPU the maximum number of buffers that a task can use during an execution. For example, in the Cholesky factorization (dense linear algebra application), the GEMM task uses up to 3 buffers, so it is possible to set the maximum number of task buffers to 3 to run a Cholesky factorization on StarPU.

How to reuse memory

When your application needs to allocate more data than the available amount of memory usable by StarPU (given by starpu_memory_get_available() ), the allocation cache system can reuse data buffers used by previously executed tasks. For that system to work with MPI tasks, you need to submit tasks progressively instead of as soon as possible, because in the case of MPI receives, the allocation cache check for reusing data buffers will be done at submission time, not at execution time.

You have two options to control the task submission flow. The first one is by controlling the number of submitted tasks during the whole execution. This can be done whether by setting the environment variables STARPU_LIMIT_MAX_NSUBMITTED_TASKS and STARPU_LIMIT_MIN_NSUBMITTED_TASKS to tell StarPU when to stop submitting tasks and when to wake up and submit tasks again, or by explicitely calling starpu_task_wait_for_n_submitted() in your application code for finest grain control (for example, between two iterations of a submission loop).

The second option is to control the memory size of the allocation cache. This can be done in the application by using jointly starpu_memory_get_available() and starpu_memory_wait_available() to submit tasks only when there is enough memory space to allocate the data needed by the task, i.e when enough data are available for reuse in the allocation cache.

Performance Model Calibration

Most schedulers are based on an estimation of codelet duration on each kind of processing unit. For this to be possible, the application programmer needs to configure a performance model for the codelets of the application (see PerformanceModelExample for instance). History-based performance models use on-line calibration. StarPU will automatically calibrate codelets which have never been calibrated yet, and save the result in $STARPU_HOME/.starpu/sampling/codelets. The models are indexed by machine name. To share the models between machines (e.g. for a homogeneous cluster), use export STARPU_HOSTNAME=some_global_name. To force continuing calibration, use export STARPU_CALIBRATE=1 . This may be necessary if your application has not-so-stable performance. StarPU will force calibration (and thus ignore the current result) until 10 (_STARPU_CALIBRATION_MINIMUM) measurements have been made on each architecture, to avoid badly scheduling tasks just because the first measurements were not so good. Details on the current performance model status can be obtained from the command starpu_perfmodel_display: the -l option lists the available performance models, and the -s option permits to choose the performance model to be displayed. The result looks like:

$ starpu_perfmodel_display -s starpu_slu_lu_model_11
performance model for cpu_impl_0
# hash    size     flops         mean          dev           n
914f3bef  1048576  0.000000e+00  2.503577e+04  1.982465e+02  8
3e921964  65536    0.000000e+00  5.527003e+02  1.848114e+01  7
e5a07e31  4096     0.000000e+00  1.717457e+01  5.190038e+00  14
...

Which shows that for the LU 11 kernel with a 1MiB matrix, the average execution time on CPUs was about 25ms, with a 0.2ms standard deviation, over 8 samples. It is a good idea to check this before doing actual performance measurements.

A graph can be drawn by using the tool starpu_perfmodel_plot:

$ starpu_perfmodel_plot -s starpu_slu_lu_model_11
4096 16384 65536 262144 1048576 4194304 
$ gnuplot starpu_starpu_slu_lu_model_11.gp
$ gv starpu_starpu_slu_lu_model_11.eps
starpu_starpu_slu_lu_model_11.png

If a kernel source code was modified (e.g. performance improvement), the calibration information is stale and should be dropped, to re-calibrate from start. This can be done by using export STARPU_CALIBRATE=2.

Note: history-based performance models get calibrated only if a performance-model-based scheduler is chosen.

The history-based performance models can also be explicitly filled by the application without execution, if e.g. the application already has a series of measurements. This can be done by using starpu_perfmodel_update_history(), for instance:

static struct starpu_perfmodel perf_model = {
.type = STARPU_HISTORY_BASED,
.symbol = "my_perfmodel",
};
struct starpu_codelet cl = {
.where = STARPU_CUDA,
.cuda_funcs = { cuda_func1, cuda_func2},
.nbuffers = 1,
.modes = {STARPU_W},
.model = &perf_model
};
void feed(void) {
struct my_measure *measure;
struct starpu_task task;
starpu_task_init(&task);
task.cl = &cl;
for (measure = &measures[0]; measure < measures[last]; measure++) {
starpu_data_handle_t handle;
starpu_vector_data_register(&handle, -1, 0, measure->size, sizeof(float));
task.handles[0] = handle;
starpu_perfmodel_update_history(&perf_model, &task,
STARPU_CUDA_DEFAULT + measure->cudadev, 0,
measure->implementation, measure->time);
starpu_task_clean(&task);
starpu_data_unregister(handle);
}
}

Measurement has to be provided in milliseconds for the completion time models, and in Joules for the energy consumption models.

Task Distribution Vs Data Transfer

Distributing tasks to balance the load induces data transfer penalty. StarPU thus needs to find a balance between both. The target function that the scheduler dmda of StarPU tries to minimize is alpha * T_execution + beta * T_data_transfer, where T_execution is the estimated execution time of the codelet (usually accurate), and T_data_transfer is the estimated data transfer time. The latter is estimated based on bus calibration before execution start, i.e. with an idle machine, thus without contention. You can force bus re-calibration by running the tool starpu_calibrate_bus. The beta parameter defaults to 1, but it can be worth trying to tweak it by using export STARPU_SCHED_BETA=2 for instance, since during real application execution, contention makes transfer times bigger. This is of course imprecise, but in practice, a rough estimation already gives the good results that a precise estimation would give.

Data Prefetch

The scheduling policies heft, dmda and pheft perform data prefetch (see STARPU_PREFETCH): as soon as a scheduling decision is taken for a task, requests are issued to transfer its required data to the target processing unit, if needed, so that when the processing unit actually starts the task, its data will hopefully be already available and it will not have to wait for the transfer to finish.

The application may want to perform some manual prefetching, for several reasons such as excluding initial data transfers from performance measurements, or setting up an initial statically-computed data distribution on the machine before submitting tasks, which will thus guide StarPU toward an initial task distribution (since StarPU will try to avoid further transfers).

This can be achieved by giving the function starpu_data_prefetch_on_node() the handle and the desired target memory node.

Power-based Scheduling

If the application can provide some power performance model (through the field starpu_codelet::power_model), StarPU will take it into account when distributing tasks. The target function that the scheduler dmda minimizes becomes alpha * T_execution + beta * T_data_transfer + gamma * Consumption , where Consumption is the estimated task consumption in Joules. To tune this parameter, use export STARPU_SCHED_GAMMA=3000 for instance, to express that each Joule (i.e kW during 1000us) is worth 3000us execution time penalty. Setting alpha and beta to zero permits to only take into account power consumption.

This is however not sufficient to correctly optimize power: the scheduler would simply tend to run all computations on the most energy-conservative processing unit. To account for the consumption of the whole machine (including idle processing units), the idle power of the machine should be given by setting export STARPU_IDLE_POWER=200 for 200W, for instance. This value can often be obtained from the machine power supplier.

The power actually consumed by the total execution can be displayed by setting export STARPU_PROFILING=1 STARPU_WORKER_STATS=1 .

On-line task consumption measurement is currently only supported through the CL_PROFILING_POWER_CONSUMED OpenCL extension, implemented in the MoviSim simulator. Applications can however provide explicit measurements by using the function starpu_perfmodel_update_history() (examplified in PerformanceModelExample with the power_model performance model). Fine-grain measurement is often not feasible with the feedback provided by the hardware, so the user can for instance run a given task a thousand times, measure the global consumption for that series of tasks, divide it by a thousand, repeat for varying kinds of tasks and task sizes, and eventually feed StarPU with these manual measurements through starpu_perfmodel_update_history(). For instance, for CUDA devices, nvidia-smi -q -d POWER can be used to get the current consumption in Watt. Multiplying that value by the average duration of a single task gives the consumption of the task in Joules, which can be given to starpu_perfmodel_update_history().

Static Scheduling

In some cases, one may want to force some scheduling, for instance force a given set of tasks to GPU0, another set to GPU1, etc. while letting some other tasks be scheduled on any other device. This can indeed be useful to guide StarPU into some work distribution, while still letting some degree of dynamism. For instance, to force execution of a task on CUDA0:

task->execute_on_a_specific_worker = 1;
task->worker = starpu_worker_get_by_type(STARPU_CUDA_WORKER, 0);

Note however that using scheduling contexts while statically scheduling tasks on workers could be tricky. Be careful to schedule the tasks exactly on the workers of the corresponding contexts, otherwise the workers' corresponding scheduling structures may not be allocated or the execution of the application may deadlock. Moreover, the hypervisor should not be used when statically scheduling tasks.

Profiling

A quick view of how many tasks each worker has executed can be obtained by setting export STARPU_WORKER_STATS=1 This is a convenient way to check that execution did happen on accelerators without penalizing performance with the profiling overhead.

A quick view of how much data transfers have been issued can be obtained by setting export STARPU_BUS_STATS=1 .

More detailed profiling information can be enabled by using export STARPU_PROFILING=1 or by calling starpu_profiling_status_set() from the source code. Statistics on the execution can then be obtained by using export STARPU_BUS_STATS=1 and export STARPU_WORKER_STATS=1 . More details on performance feedback are provided by the next chapter.

Detection Stuck Conditions

It may happen that for some reason, StarPU does not make progress for a long period of time. Reason are sometimes due to contention inside StarPU, but sometimes this is due to external reasons, such as stuck MPI driver, or CUDA driver, etc.

export STARPU_WATCHDOG_TIMEOUT=10000

allows to make StarPU print an error message whenever StarPU does not terminate any task for 10ms. In addition to that,

export STARPU_WATCHDOG_CRASH=1

raises SIGABRT in that condition, thus allowing to catch the situation in gdb. It can also be useful to type "handle SIGABRT nopass" in gdb to be able to let the process continue, after inspecting the state of the process.

CUDA-specific Optimizations

Due to CUDA limitations, StarPU will have a hard time overlapping its own communications and the codelet computations if the application does not use a dedicated CUDA stream for its computations instead of the default stream, which synchronizes all operations of the GPU. StarPU provides one by the use of starpu_cuda_get_local_stream() which can be used by all CUDA codelet operations to avoid this issue. For instance:

func <<<grid,block,0,starpu_cuda_get_local_stream()>>> (foo, bar);
cudaStreamSynchronize(starpu_cuda_get_local_stream());

Calling starpu_cublas_init() makes StarPU already do appropriate calls for the CUBLAS library. Some libraries like Magma may however change the current stream, one then has to call cublasSetKernelStream(starpu_cuda_get_local_stream()); at the beginning of the codelet to make sure that CUBLAS is really using the proper stream.

Unfortunately, some CUDA libraries do not have stream variants of kernels. That will lower the potential for overlapping.

Performance Debugging

To get an idea of what is happening, a lot of performance feedback is available, detailed in the next chapter. The various informations should be checked for.

  • What does the Gantt diagram look like? (see Creating a Gantt Diagram)
    • If it's mostly green (tasks running in the initial context) or context specific color prevailing, then the machine is properly utilized, and perhaps the codelets are just slow. Check their performance, see Performance Of Codelets.
    • If it's mostly purple (FetchingInput), tasks keep waiting for data transfers, do you perhaps have far more communication than computation? Did you properly use CUDA streams to make sure communication can be overlapped? Did you use data-locality aware schedulers to avoid transfers as much as possible?
    • If it's mostly red (Blocked), tasks keep waiting for dependencies, do you have enough parallelism? It might be a good idea to check what the DAG looks like (see Creating a DAG With Graphviz).
    • If only some workers are completely red (Blocked), for some reason the scheduler didn't assign tasks to them. Perhaps the performance model is bogus, check it (see Performance Of Codelets). Do all your codelets have a performance model? When some of them don't, the schedulers switches to a greedy algorithm which thus performs badly.

You can also use the Temanejo task debugger (see Using The Temanejo Task Debugger) to visualize the task graph more easily.

Simulated Performance

StarPU can use Simgrid in order to simulate execution on an arbitrary platform.

your application for simulation.

There are a few technical details which need to be handled for an application to be simulated through Simgrid.

If the application uses gettimeofday to make its performance measurements, the real time will be used, which will be bogus. To get the simulated time, it has to use starpu_timing_now() which returns the virtual timestamp in us.

For some technical reason, the application's .c file which contains main() has to be recompiled with starpu_simgrid_wrap.h, which in the simgrid case will # define main() into starpu_main(), and it is libstarpu which will provide the real main() and will call the application's main().

To be able to test with crazy data sizes, one may want to only allocate application data if STARPU_SIMGRID is not defined. Passing a NULL pointer to starpu_data_register functions is fine, data will never be read/written to by StarPU in Simgrid mode anyway.

To be able to run the application with e.g. CUDA simulation on a system which does not have CUDA installed, one can fill the cuda_funcs with (void*)1, to express that there is a CUDA implementation, even if one does not actually provide it. StarPU will never actually run it in Simgrid mode anyway.

Calibration

The idea is to first compile StarPU normally, and run the application, so as to automatically benchmark the bus and the codelets.

$ ./configure && make
$ STARPU_SCHED=dmda ./examples/matvecmult/matvecmult
[starpu][_starpu_load_history_based_model] Warning: model matvecmult
   is not calibrated, forcing calibration for this run. Use the
   STARPU_CALIBRATE environment variable to control this.
$ ...
$ STARPU_SCHED=dmda ./examples/matvecmult/matvecmult
TEST PASSED

Note that we force to use the scheduler dmda to generate performance models for the application. The application may need to be run several times before the model is calibrated.

Simulation

Then, recompile StarPU, passing --enable-simgrid to ./configure.

$ ./configure --enable-simgrid

To specify the location of SimGrid, you can either set the environment variables SIMGRID_CFLAGS and SIMGRID_LIBS, or use the configure options --with-simgrid-dir, --with-simgrid-include-dir and --with-simgrid-lib-dir, for example

$ ./configure --with-simgrid-dir=/opt/local/simgrid

You can then re-run the application.

$ make
$ STARPU_SCHED=dmda ./examples/matvecmult/matvecmult
TEST FAILED !!!

It is normal that the test fails: since the computation are not actually done (that is the whole point of simgrid), the result is wrong, of course.

If the performance model is not calibrated enough, the following error message will be displayed

$ STARPU_SCHED=dmda ./examples/matvecmult/matvecmult
[starpu][_starpu_load_history_based_model] Warning: model matvecmult
    is not calibrated, forcing calibration for this run. Use the
    STARPU_CALIBRATE environment variable to control this.
[starpu][_starpu_simgrid_execute_job][assert failure] Codelet
    matvecmult does not have a perfmodel, or is not calibrated enough

The number of devices can be chosen as usual with STARPU_NCPU, STARPU_NCUDA, and STARPU_NOPENCL, and the amount of GPU memory with STARPU_LIMIT_CUDA_MEM, STARPU_LIMIT_CUDA_devid_MEM, STARPU_LIMIT_OPENCL_MEM, and STARPU_LIMIT_OPENCL_devid_MEM.

Simulation On Another Machine

The simgrid support even permits to perform simulations on another machine, your desktop, typically. To achieve this, one still needs to perform the Calibration step on the actual machine to be simulated, then copy them to your desktop machine (the $STARPU_HOME/.starpu directory). One can then perform the Simulation step on the desktop machine, by setting the environment variable STARPU_HOSTNAME to the name of the actual machine, to make StarPU use the performance models of the simulated machine even on the desktop machine.

If the desktop machine does not have CUDA or OpenCL, StarPU is still able to use simgrid to simulate execution with CUDA/OpenCL devices, but the application source code will probably disable the CUDA and OpenCL codelets in thatcd sc case. Since during simgrid execution, the functions of the codelet are actually not called, one can use dummy functions such as the following to still permit CUDA or OpenCL execution:

Simulation examples

StarPU ships a few performance models for a couple of systems: attila and mirage. See section Simulated benchmarks for the details.

simulation

The simulation can be tweaked, to be able to tune it between a very accurate simulation and a very simple simulation (which is thus close to scheduling theory results), see the STARPU_SIMGRID_CUDA_MALLOC_COST and STARPU_SIMGRID_CUDA_QUEUE_COST environment variables.

applications

By default, simgrid uses its own implementation of threads, which prevents gdb from being able to inspect stacks of all threads. To be able to fully debug an application running with simgrid, pass the –cfg=contexts/factory:thread option to the application, to make simgrid use system threads, which gdb will be able to manipulate as usual.

Field Documentation

starpu_data_filter::filter_func

This function fills the child_interface structure with interface information for the id-th child of the parent father_interface (among nparts).

starpu_data_filter::nchildren

This is the number of parts to partition the data into.

starpu_data_filter::get_nchildren

Allow to define an additional pointer parameter for the filter function, such as the sizes of the different parts.

Function Documentation

void starpu_data_partition ( starpu_data_handle_t  initial_handle,
struct starpu_data_filter *  f 
)

This requests partitioning one StarPU data initial_handle into several subdata according to the filter f.

Here an example of how to use the function.

struct starpu_data_filter f = {
.filter_func = starpu_matrix_filter_block,
.nchildren = nslicesx,
.get_nchildren = NULL,
.get_child_ops = NULL
};
starpu_data_partition(A_handle, &f);
void starpu_data_unpartition ( starpu_data_handle_t  root_data,
unsigned  gathering_node 
)

This unapplies one filter, thus unpartitioning the data. The pieces of data are collected back into one big piece in the gathering_node (usually 0). Tasks working on the partitioned data must be already finished when calling starpu_data_unpartition().

Here an example of how to use the function.

starpu_data_unpartition(A_handle, 0);
int starpu_data_get_nb_children ( starpu_data_handle_t  handle)

This function returns the number of children.

starpu_data_handle_t starpu_data_get_child ( starpu_data_handle_t  handle,
unsigned  i 
)

Return the ith child of the given handle, which must have been partitionned beforehand.

starpu_data_handle_t starpu_data_get_sub_data ( starpu_data_handle_t  root_data,
unsigned  depth,
  ... 
)

After partitioning a StarPU data by applying a filter, starpu_data_get_sub_data() can be used to get handles for each of the data portions. root_data is the parent data that was partitioned. depth is the number of filters to traverse (in case several filters have been applied, to e.g. partition in row blocks, and then in column blocks), and the subsequent parameters are the indexes. The function returns a handle to the subdata.

Here an example of how to use the function.

h = starpu_data_get_sub_data(A_handle, 1, taskx);
starpu_data_handle_t starpu_data_vget_sub_data ( starpu_data_handle_t  root_data,
unsigned  depth,
va_list  pa 
)

This function is similar to starpu_data_get_sub_data() but uses a va_list for the parameter list.

void starpu_data_map_filters ( starpu_data_handle_t  root_data,
unsigned  nfilters,
  ... 
)

Applies nfilters filters to the handle designated by root_handle recursively. nfilters pointers to variables of the type starpu_data_filter should be given.

void starpu_data_vmap_filters ( starpu_data_handle_t  root_data,
unsigned  nfilters,
va_list  pa 
)

Applies nfilters filters to the handle designated by root_handle recursively. It uses a va_list of pointers to variables of the type starpu_data_filter.

void starpu_vector_filter_block ( void *  father_interface,
void *  child_interface,
struct starpu_data_filter *  f,
unsigned  id,
unsigned  nparts 
)

Return in child_interface the id th element of the vector represented by father_interface once partitioned in nparts chunks of equal size.

void starpu_vector_filter_block_shadow ( void *  father_interface,
void *  child_interface,
struct starpu_data_filter *  f,
unsigned  id,
unsigned  nparts 
)

Return in child_interface the id th element of the vector represented by father_interface once partitioned in nparts chunks of equal size with a shadow border filter_arg_ptr, thus getting a vector of size (n-2*shadow)/nparts+2*shadow. The filter_arg_ptr field of f must be the shadow size casted into void*. IMPORTANT: This can only be used for read-only access, as no coherency is enforced for the shadowed parts. An usage example is available in examples/filters/shadow.c

void starpu_vector_filter_list ( void *  father_interface,
void *  child_interface,
struct starpu_data_filter *  f,
unsigned  id,
unsigned  nparts 
)

Return in child_interface the id th element of the vector represented by father_interface once partitioned into nparts chunks according to the filter_arg_ptr field of f. The filter_arg_ptr field must point to an array of nparts uint32_t elements, each of which specifies the number of elements in each chunk of the partition.

void starpu_vector_filter_divide_in_2 ( void *  father_interface,
void *  child_interface,
struct starpu_data_filter *  f,
unsigned  id,
unsigned  nparts 
)

Return in child_interface the id th element of the vector represented by father_interface once partitioned in 2 chunks of equal size, ignoring nparts. Thus, id must be 0 or 1.

void starpu_matrix_filter_block ( void *  father_interface,
void *  child_interface,
struct starpu_data_filter *  f,
unsigned  id,
unsigned  nparts 
)

This partitions a dense Matrix along the x dimension, thus getting (x/nparts ,y) matrices. If nparts does not divide x, the last submatrix contains the remainder.

void starpu_matrix_filter_block_shadow ( void *  father_interface,
void *  child_interface,
struct starpu_data_filter *  f,
unsigned  id,
unsigned  nparts

Execution Configuration Through Environment Variables

The behavior of the StarPU library and tools may be tuned thanks to the following environment variables.

Configuring Workers

STARPU_NCPU

Specify the number of CPU workers (thus not including workers dedicated to control accelerators). Note that by default, StarPU will not allocate more CPU workers than there are physical CPUs, and that some CPUs are used to control the accelerators.

STARPU_NCPUS

This variable is deprecated. You should use STARPU_NCPU.

STARPU_NCUDA

Specify the number of CUDA devices that StarPU can use. If STARPU_NCUDA is lower than the number of physical devices, it is possible to select which CUDA devices should be used by the means of the environment variable STARPU_WORKERS_CUDAID. By default, StarPU will create as many CUDA workers as there are CUDA devices.

STARPU_NOPENCL

OpenCL equivalent of the environment variable STARPU_NCUDA.

STARPU_OPENCL_ON_CPUS

By default, the OpenCL driver only enables GPU and accelerator devices. By setting the environment variable STARPU_OPENCL_ON_CPUS to 1, the OpenCL driver will also enable CPU devices.

STARPU_OPENCL_ONLY_ON_CPUS

By default, the OpenCL driver enables GPU and accelerator devices. By setting the environment variable STARPU_OPENCL_ONLY_ON_CPUS to 1, the OpenCL driver will ONLY enable CPU devices.

STARPU_WORKERS_NOBIND

Setting it to non-zero will prevent StarPU from binding its threads to CPUs. This is for instance useful when running the testsuite in parallel.

STARPU_WORKERS_CPUID

Passing an array of integers (starting from 0) in STARPU_WORKERS_CPUID specifies on which logical CPU the different workers should be bound. For instance, if STARPU_WORKERS_CPUID = "0 1 4 5", the first worker will be bound to logical CPU #0, the second CPU worker will be bound to logical CPU #1 and so on. Note that the logical ordering of the CPUs is either determined by the OS, or provided by the library hwloc in case it is available.

Note that the first workers correspond to the CUDA workers, then come the OpenCL workers, and finally the CPU workers. For example if we have STARPU_NCUDA=1, STARPU_NOPENCL=1, STARPU_NCPU=2 and STARPU_WORKERS_CPUID = "0 2 1 3", the CUDA device will be controlled by logical CPU #0, the OpenCL device will be controlled by logical CPU #2, and the logical CPUs #1 and #3 will be used by the CPU workers.

If the number of workers is larger than the array given in STARPU_WORKERS_CPUID, the workers are bound to the logical CPUs in a round-robin fashion: if STARPU_WORKERS_CPUID = "0 1", the first and the third (resp. second and fourth) workers will be put on CPU #0 (resp. CPU #1).

This variable is ignored if the field starpu_conf::use_explicit_workers_bindid passed to starpu_init() is set.

STARPU_WORKERS_CUDAID

Similarly to the STARPU_WORKERS_CPUID environment variable, it is possible to select which CUDA devices should be used by StarPU. On a machine equipped with 4 GPUs, setting STARPU_WORKERS_CUDAID = "1 3" and STARPU_NCUDA=2 specifies that 2 CUDA workers should be created, and that they should use CUDA devices #1 and #3 (the logical ordering of the devices is the one reported by CUDA).

This variable is ignored if the field starpu_conf::use_explicit_workers_cuda_gpuid passed to starpu_init() is set.

STARPU_WORKERS_OPENCLID

OpenCL equivalent of the STARPU_WORKERS_CUDAID environment variable.

This variable is ignored if the field starpu_conf::use_explicit_workers_opencl_gpuid passed to starpu_init() is set.

STARPU_SINGLE_COMBINED_WORKER

If set, StarPU will create several workers which won't be able to work concurrently. It will by default create combined workers which size goes from 1 to the total number of CPU workers in the system. STARPU_MIN_WORKERSIZE and STARPU_MAX_WORKERSIZE can be used to change this default.

STARPU_MIN_WORKERSIZE

STARPU_MIN_WORKERSIZE permits to specify the minimum size of the combined workers (instead of the default 2)

STARPU_MAX_WORKERSIZE

STARPU_MAX_WORKERSIZE permits to specify the minimum size of the combined workers (instead of the number of CPU workers in the system)

STARPU_SYNTHESIZE_ARITY_COMBINED_WORKER

Let the user decide how many elements are allowed between combined workers created from hwloc information. For instance, in the case of sockets with 6 cores without shared L2 caches, if STARPU_SYNTHESIZE_ARITY_COMBINED_WORKER is set to 6, no combined worker will be synthesized beyond one for the socket and one per core. If it is set to 3, 3 intermediate combined workers will be synthesized, to divide the socket cores into 3 chunks of 2 cores. If it set to 2, 2 intermediate combined workers will be synthesized, to divide the the socket cores into 2 chunks of 3 cores, and then 3 additional combined workers will be synthesized, to divide the former synthesized workers into a bunch of 2 cores, and the remaining core (for which no combined worker is synthesized since there is already a normal worker for it).

The default, 2, thus makes StarPU tend to building a binary trees of combined workers.

STARPU_DISABLE_ASYNCHRONOUS_COPY

Disable asynchronous copies between CPU and GPU devices. The AMD implementation of OpenCL is known to fail when copying data asynchronously. When using this implementation, it is therefore necessary to disable asynchronous data transfers.

STARPU_DISABLE_ASYNCHRONOUS_CUDA_COPY

Disable asynchronous copies between CPU and CUDA devices.

STARPU_DISABLE_ASYNCHRONOUS_OPENCL_COPY

Disable asynchronous copies between CPU and OpenCL devices. The AMD implementation of OpenCL is known to fail when copying data asynchronously. When using this implementation, it is therefore necessary to disable asynchronous data transfers.

STARPU_ENABLE_CUDA_GPU_GPU_DIRECT

Enable (1) or Disable (0) direct CUDA transfers from GPU to GPU, without copying through RAM. The default is Enabled. This permits to test the performance effect of GPU-Direct.

STARPU_DISABLE_PINNING

Disable (1) or Enable (0) pinning host memory allocated through starpu_malloc, starpu_memory_pin and friends. The default is Enabled. This permits to test the performance effect of memory pinning.

Configuring The Scheduling Engine

STARPU_SCHED

Choose between the different scheduling policies proposed by StarPU: work random, stealing, greedy, with performance models, etc.

Use STARPU_SCHED=help to get the list of available schedulers.

STARPU_CALIBRATE

If this variable is set to 1, the performance models are calibrated during the execution. If it is set to 2, the previous values are dropped to restart calibration from scratch. Setting this variable to 0 disable calibration, this is the default behaviour.

Note: this currently only applies to dm and dmda scheduling policies.

STARPU_CALIBRATE_MINIMUM

This defines the minimum number of calibration measurements that will be made before considering that the performance model is calibrated. The default value is 10.

STARPU_BUS_CALIBRATE

If this variable is set to 1, the bus is recalibrated during intialization.

STARPU_PREFETCH

This variable indicates whether data prefetching should be enabled (0 means that it is disabled). If prefetching is enabled, when a task is scheduled to be executed e.g. on a GPU, StarPU will request an asynchronous transfer in advance, so that data is already present on the GPU when the task starts. As a result, computation and data transfers are overlapped. Note that prefetching is enabled by default in StarPU.

STARPU_SCHED_ALPHA

To estimate the cost of a task StarPU takes into account the estimated computation time (obtained thanks to performance models). The alpha factor is the coefficient to be applied to it before adding it to the communication part.

STARPU_SCHED_BETA

To estimate the cost of a task StarPU takes into account the estimated data transfer time (obtained thanks to performance models). The beta factor is the coefficient to be applied to it before adding it to the computation part.

STARPU_SCHED_GAMMA

Define the execution time penalty of a joule (Power-based Scheduling).

STARPU_IDLE_POWER

Define the idle power of the machine (Power-based Scheduling).

STARPU_PROFILING

Enable on-line performance monitoring (Enabling On-line Performance Monitoring).

Extensions

SOCL_OCL_LIB_OPENCL

THE SOCL test suite is only run when the environment variable SOCL_OCL_LIB_OPENCL is defined. It should contain the location of the file libOpenCL.so of the OCL ICD implementation.

OCL_ICD_VENDORS

When using SOCL with OpenCL ICD (https://forge.imag.fr/projects/ocl-icd/), this variable may be used to point to the directory where ICD files are installed. The default directory is /etc/OpenCL/vendors. StarPU installs ICD files in the directory $prefix/share/starpu/opencl/vendors.

STARPU_COMM_STATS

Communication statistics for starpumpi (MPI Support) will be enabled when the environment variable STARPU_COMM_STATS is defined to an value other than 0.

STARPU_MPI_CACHE

Communication cache for starpumpi (MPI Support) will be disabled when the environment variable STARPU_MPI_CACHE is set to 0. It is enabled by default or for any other values of the variable STARPU_MPI_CACHE.

STARPU_MPI_CACHE_STATS

When set to 1, statistics are enabled for the communication cache (MPI Support). For now, it prints messages on the standard output when data are added or removed from the received communication cache.

Miscellaneous And Debug

STARPU_HOME

This specifies the main directory in which StarPU stores its configuration files. The default is $HOME on Unix environments, and $USERPROFILE on Windows environments.

STARPU_PERF_MODEL_DIR

This specifies the main directory in which StarPU stores its performance model files. The default is $STARPU_HOME/.starpu/sampling.

STARPU_HOSTNAME

When set, force the hostname to be used when dealing performance model files. Models are indexed by machine name. When running for example on a homogenenous cluster, it is possible to share the models between machines by setting export STARPU_HOSTNAME=some_global_name.

STARPU_OPENCL_PROGRAM_DIR

This specifies the directory where the OpenCL codelet source files are located. The function starpu_opencl_load_program_source() looks for the codelet in the current directory, in the directory specified by the environment variable STARPU_OPENCL_PROGRAM_DIR, in the directory share/starpu/opencl of the installation directory of StarPU, and finally in the source directory of StarPU.

STARPU_SILENT

This variable allows to disable verbose mode at runtime when StarPU has been configured with the option --enable-verbose. It also disables the display of StarPU information and warning messages.

STARPU_LOGFILENAME

This variable specifies in which file the debugging output should be saved to.

STARPU_FXT_PREFIX

This variable specifies in which directory to save the trace generated if FxT is enabled. It needs to have a trailing '/' character.

STARPU_LIMIT_CUDA_devid_MEM

This variable specifies the maximum number of megabytes that should be available to the application on the CUDA device with the identifier devid. This variable is intended to be used for experimental purposes as it emulates devices that have a limited amount of memory. When defined, the variable overwrites the value of the variable STARPU_LIMIT_CUDA_MEM.

STARPU_LIMIT_CUDA_MEM

This variable specifies the maximum number of megabytes that should be available to the application on each CUDA devices. This variable is intended to be used for experimental purposes as it emulates devices that have a limited amount of memory.

STARPU_LIMIT_OPENCL_devid_MEM

This variable specifies the maximum number of megabytes that should be available to the application on the OpenCL device with the identifier devid. This variable is intended to be used for experimental purposes as it emulates devices that have a limited amount of memory. When defined, the variable overwrites the value of the variable STARPU_LIMIT_OPENCL_MEM.

STARPU_LIMIT_OPENCL_MEM

This variable specifies the maximum number of megabytes that should be available to the application on each OpenCL devices. This variable is intended to be used for experimental purposes as it emulates devices that have a limited amount of memory.

STARPU_LIMIT_CPU_MEM

This variable specifies the maximum number of megabytes that should be available to the application on each CPU device. This variable is intended to be used for experimental purposes as it emulates devices that have a limited amount of memory. Setting it enables allocation cache in main memory

STARPU_LIMIT_MAX_NSUBMITTED_TASKS

This variable allows the user to control the task submission flow by specifying to StarPU a maximum number of submitted tasks allowed at a given time, i.e. when this limit is reached task submission becomes blocking until enough tasks have completed, specified by STARPU_LIMIT_MIN_NSUBMITTED_TASKS. Setting it enables allocation cache buffer reuse in main memory.

STARPU_LIMIT_MIN_NSUBMITTED_TASKS

This variable allows the user to control the task submission flow by specifying to StarPU a submitted task threshold to wait before unblocking task submission. This variable has to be used in conjunction with STARPU_LIMIT_MAX_NSUBMITTED_TASKS which puts the task submission thread to sleep. Setting it enables allocation cache buffer reuse in main memory.

STARPU_TRACE_BUFFER_SIZE

This sets the buffer size for recording trace events in MiB. Setting it to a big size allows to avoid pauses in the trace while it is recorded on the disk. This however also consumes memory, of course. The default value is 64.

STARPU_GENERATE_TRACE

When set to 1, this variable indicates that StarPU should automatically generate a Paje trace when starpu_shutdown() is called.

STARPU_MEMORY_STATS

When set to 0, disable the display of memory statistics on data which have not been unregistered at the end of the execution (Memory Feedback).

STARPU_BUS_STATS

When defined, statistics about data transfers will be displayed when calling starpu_shutdown() (Profiling).

STARPU_WORKER_STATS

When defined, statistics about the workers will be displayed when calling starpu_shutdown() (Profiling). When combined with the environment variable STARPU_PROFILING, it displays the power consumption (Power-based Scheduling).

STARPU_STATS

When set to 0, data statistics will not be displayed at the end of the execution of an application (Data Statistics).

STARPU_WATCHDOG_TIMEOUT

When set to a value other than 0, allows to make StarPU print an error message whenever StarPU does not terminate any task for the given time (in µs). Should be used in combination with STARPU_WATCHDOG_CRASH (see Detection Stuck Conditions).

STARPU_WATCHDOG_CRASH

When set to a value other than 0, it triggers a crash when the watch dog is reached, thus allowing to catch the situation in gdb, etc (see Detection Stuck Conditions)

STARPU_DISABLE_KERNELS

When set to a value other than 1, it disables actually calling the kernel functions, thus allowing to quickly check that the task scheme is working properly, without performing the actual application-provided computation.

STARPU_RAND_SEED

The random scheduler and some examples use random numbers for their own working. Depending on the examples, the seed is by default juste always 0 or the current time() (unless simgrid mode is enabled, in which case it is always 0). STARPU_RAND_SEED allows to set the seed to a specific value.

Configuring The Hypervisor

SC_HYPERVISOR_POLICY

Choose between the different resizing policies proposed by StarPU for the hypervisor: idle, app_driven, feft_lp, teft_lp; ispeed_lp, throughput_lp etc.

Use SC_HYPERVISOR_POLICY=help to get the list of available policies for the hypervisor

SC_HYPERVISOR_TRIGGER_RESIZE

Choose how should the hypervisor be triggered: speed if the resizing algorithm should be called whenever the speed of the context does not correspond to an optimal precomputed value, idle it the resizing algorithm should be called whenever the workers are idle for a period longer than the value indicated when configuring the hypervisor.

SC_HYPERVISOR_START_RESIZE

Indicate the moment when the resizing should be available. The value correspond to the percentage of the total time of execution of the application. The default value is the resizing frame.

SC_HYPERVISOR_MAX_SPEED_GAP

Indicate the ratio of speed difference between contexts that should trigger the hypervisor. This situation may occur only when a theoretical speed could not be computed and the hypervisor has no value to compare the speed to. Otherwise the resizing of a context is not influenced by the the speed of the other contexts, but only by the the value that a context should have.

SC_HYPERVISOR_STOP_PRINT

By default the values of the speed of the workers is printed during the execution of the application. If the value 1 is given to this environment variable this printing is not done.

SC_HYPERVISOR_LAZY_RESIZE

By default the hypervisor resizes the contexts in a lazy way, that is workers are firstly added to a new context before removing them from the previous one. Once this workers are clearly taken into account into the new context (a task was poped there) we remove them from the previous one. However if the application would like that the change in the distribution of workers should change right away this variable should be set to 0

SC_HYPERVISOR_SAMPLE_CRITERIA

By default the hypervisor uses a sample of flops when computing the speed of the contexts and of the workers. If this variable is set to time the hypervisor uses a sample of time (10% of an aproximation of the total execution time of the application)

Detailed Description

StarPU permits on one hand grouping workers in combined workers in order to execute a parallel task and on the other hand grouping tasks in bundles that will be executed by a single specified worker. In contrast when we group workers in scheduling contexts we submit starpu tasks to them and we schedule them with the policy assigned to the context. Scheduling contexts can be created, deleted and modified dynamically.

Macro Definition Documentation

#define STARPU_SCHED_CTX_POLICY_NAME

This macro is used when calling starpu_sched_ctx_create() to specify a name for a scheduling policy

#define STARPU_SCHED_CTX_POLICY_STRUCT

This macro is used when calling starpu_sched_ctx_create() to specify a pointer to a scheduling policy

#define STARPU_SCHED_CTX_POLICY_MIN_PRIO

This macro is used when calling starpu_sched_ctx_create() to specify a minimum scheduler priority value.

#define STARPU_SCHED_CTX_POLICY_MAX_PRIO

This macro is used when calling starpu_sched_ctx_create() to specify a maximum scheduler priority value.

#define STARPU_MIN_PRIO

Provided for legacy reasons.

#define STARPU_MAX_PRIO

Provided for legacy reasons.

#define STARPU_DEFAULT_PRIO

By convention, the default priority level should be 0 so that we can statically allocate tasks with a default priority.

Function Documentation

unsigned starpu_sched_ctx_create ( int *  workerids_ctx,
int  nworkers_ctx,
const char *  sched_ctx_name,
  ... 
)

This function creates a scheduling context with the given parameters (see below) and assigns the workers in workerids_ctx to execute the tasks submitted to it. The return value represents the identifier of the context that has just been created. It will be further used to indicate the context the tasks will be submitted to. The return value should be at most STARPU_NMAX_SCHED_CTXS.

The arguments following the name of the scheduling context can be of the following types:

unsigned starpu_sched_ctx_create_inside_interval ( const char *  policy_name,
const char *  sched_ctx_name,
int  min_ncpus,
int  max_ncpus,
int  min_ngpus,
int  max_ngpus,
unsigned  allow_overlap 
)

Create a context indicating an approximate interval of resources

void starpu_sched_ctx_register_close_callback ( unsigned  sched_ctx_id,
void(*)(unsigned sched_ctx_id, void *args)  close_callback,
void *  args 
)

Execute the callback whenever the last task of the context finished executing, it is called with the pramaters: sched_ctx and any other paramter needed by the application (packed in a void*)

void starpu_sched_ctx_add_workers ( int *  workerids_ctx,
int  nworkers_ctx,
unsigned  sched_ctx_id 
)

This function adds dynamically the workers in workerids_ctx to the context sched_ctx_id. The last argument cannot be greater than STARPU_NMAX_SCHED_CTXS.

void starpu_sched_ctx_remove_workers ( int *  workerids_ctx,
int  nworkers_ctx,
unsigned  sched_ctx_id 
)

This function removes the workers in workerids_ctx from the context sched_ctx_id. The last argument cannot be greater than STARPU_NMAX_SCHED_CTXS.

void starpu_sched_ctx_delete ( unsigned  sched_ctx_id)

Delete scheduling context sched_ctx_id and transfer remaining workers to the inheritor scheduling context.

void starpu_sched_ctx_set_inheritor ( unsigned  sched_ctx_id,
unsigned  inheritor 
)

Indicate which context whill inherit the resources of this context when he will be deleted.

void starpu_sched_ctx_set_context ( unsigned *  sched_ctx_id)

Set the scheduling context the subsequent tasks will be submitted to

unsigned starpu_sched_ctx_get_context ( void  )

Return the scheduling context the tasks are currently submitted to, or ::STARPU_NMAX_SCHED_CTXS if no default context has been defined by calling the function starpu_sched_ctx_set_context().

void starpu_sched_ctx_stop_task_submission ( void  )

Stop submitting tasks from the empty context list until the next time the context has time to check the empty context list

void starpu_sched_ctx_finished_submit ( unsigned  sched_ctx_id)

Indicate starpu that the application finished submitting to this context in order to move the workers to the inheritor as soon as possible.

unsigned starpu_sched_ctx_get_workers_list ( unsigned  sched_ctx_id,
int **  workerids 
)

Returns the list of workers in the array workerids, the returned value is the number of workers. The user should free the workerids table after finishing using it (it is allocated inside the function with the proper size)

unsigned starpu_sched_ctx_get_nworkers ( unsigned  sched_ctx_id)

Return the number of workers managed by the specified contexts (Usually needed to verify if it manages any workers or if it should be blocked)

unsigned starpu_sched_ctx_get_nshared_workers ( unsigned  sched_ctx_id,
unsigned  sched_ctx_id2 
)

Return the number of workers shared by two contexts.

unsigned starpu_sched_ctx_contains_worker ( int  workerid,
unsigned  sched_ctx_id 
)

Return 1 if the worker belongs to the context and 0 otherwise

unsigned starpu_sched_ctx_worker_get_id ( unsigned  sched_ctx_id)

Return the workerid if the worker belongs to the context and -1 otherwise. If the thread calling this function is not a worker the function returns -1 as it calls the function starpu_worker_get_id()

unsigned starpu_sched_ctx_overlapping_ctxs_on_worker ( int  workerid)

Check if a worker is shared between several contexts

int starpu_sched_ctx_set_min_priority ( unsigned  sched_ctx_id,
int  min_prio 
)

Defines the minimum task priority level supported by the scheduling policy of the given scheduler context. The default minimum priority level is the same as the default priority level which is 0 by convention. The application may access that value by calling the function starpu_sched_ctx_get_min_priority(). This function should only be called from the initialization method of the scheduling policy, and should not be used directly from the application.

int starpu_sched_ctx_set_max_priority ( unsigned  sched_ctx_id,
int  max_prio 
)

Defines the maximum priority level supported by the scheduling policy of the given scheduler context. The default maximum priority level is 1. The application may access that value by calling the starpu_sched_ctx_get_max_priority function. This function should only be called from the initialization method of the scheduling policy, and should not be used directly from the application.

int starpu_sched_ctx_get_min_priority ( unsigned  sched_ctx_id)

Returns the current minimum priority level supported by the scheduling policy of the given scheduler context.

int starpu_sched_ctx_get_max_priority ( unsigned  sched_ctx_id)

Returns the current maximum priority level supported by the scheduling policy of the given scheduler context.

struct starpu_worker_collection * starpu_sched_ctx_create_worker_collection ( unsigned  sched_ctx_id,
enum starpu_worker_collection_type  type 
)
read

Create a worker collection of the type indicated by the last parameter for the context specified through the first parameter.

void starpu_sched_ctx_delete_worker_collection ( unsigned  sched_ctx_id)

Delete the worker collection of the specified scheduling context

struct starpu_worker_collection * starpu_sched_ctx_get_worker_collection ( unsigned  sched_ctx_id)
read

Return the worker collection managed by the indicated context

void starpu_sched_ctx_set_perf_counters ( unsigned  sched_ctx_id,
void *  perf_counters 
)

Indicates to starpu the pointer to the performance counter

void starpu_sched_ctx_call_pushed_task_cb ( int  workerid,
unsigned  sched_ctx_id 
)

Callback that lets the scheduling policy tell the hypervisor that a task was pushed on a worker

void starpu_sched_ctx_notify_hypervisor_exists ( void  )

Allow the hypervisor to let starpu know he's initialised

unsigned starpu_sched_ctx_check_if_hypervisor_exists ( void  )

Ask starpu if he is informed if the hypervisor is initialised

void starpu_sched_ctx_set_policy_data ( unsigned  sched_ctx_id,
void *  policy_data 
)

Allocate the scheduling policy data (private information of the scheduler like queues, variables, additional condition variables) the context

void * starpu_sched_ctx_get_policy_data ( unsigned  sched_ctx_id)

Return the scheduling policy data (private information of the scheduler) of the contexts previously assigned to.

Function Documentation

void starpu_fxt_options_init ( struct starpu_fxt_options *  options)

todo

void starpu_fxt_generate_trace ( struct starpu_fxt_options *  options)

todo

void starpu_fxt_start_profiling ( void  )

Start recording the trace. The trace is by default started from starpu_init() call, but can be paused by using starpu_fxt_stop_profiling(), in which case starpu_fxt_start_profiling() should be called to resume recording events.

void starpu_fxt_stop_profiling ( void  )

Stop recording the trace. The trace is by default stopped when calling starpu_shutdown(). starpu_fxt_stop_profiling() can however be used to stop it earlier. starpu_fxt_start_profiling() can then be called to start recording it again, etc.

Modules
Here is a list of all modules:
oCodelet And TasksThis section describes the interface to manipulate codelets and tasks
oCUDA Extensions
oData Interfaces
oData ManagementThis section describes the data management facilities provided by StarPU. We show how to use existing data interfaces in Data Interfaces, but developers can design their own data interfaces if required
oData Partition
oExpert Mode
oExplicit Dependencies
oFFT Support
oFxT Support
oImplicit Data DependenciesIn this section, we describe how StarPU makes it possible to insert implicit task dependencies in order to enforce sequential data consistency. When this data consistency is enabled on a specific data handle, any data access will appear as sequentially consistent from the application. For instance, if the application submits two tasks that access the same piece of data in read-only mode, and then a third task that access it in write mode, dependencies will be added between the two first tasks and the third one. Implicit data dependencies are also inserted in the case of data accesses from the application

oTheoretical Lower Bound on Execution TimeCompute theoretical upper computation efficiency bound corresponding to some actual execution
oMiscellaneous Helpers
oMPI Support
oMultiformat Data Interface
oOpenCL Extensions
oParallel Tasks
oPerformance Model
oProfiling
oRunning Drivers
oScheduling ContextsStarPU permits on one hand grouping workers in combined workers in order to execute a parallel task and on the other hand grouping tasks in bundles that will be executed by a single specified worker. In contrast when we group workers in scheduling contexts we submit starpu tasks to them and we schedule them with the policy assigned to the context. Scheduling contexts can be created, deleted and modified dynamically
oScheduling PolicyTODO. While StarPU comes with a variety of scheduling policies (see Task Scheduling Policy), it may sometimes be desirable to implement custom policies to address specific problems. The API described below allows users to write their own scheduling policy
oStandard Memory Library
oTask Bundles
oTask Lists
oThreadsThis section describes the thread facilities provided by StarPU. The thread function are either implemented on top of the pthread library or the Simgrid library when the simulated performance mode is enabled (Simulated Performance)
oToolboxThe following macros allow to make GCC extensions portable, and to have a code which can be compiled with any C compiler
oStarPU-Top Interface
oVersioning
oWorkers’ Properties

Function Documentation

starpu_data_set_default_sequential_consistency_flag ( unsigned  flag)

Set the default sequential consistency flag. If a non-zero value is passed, a sequential data consistency will be enforced for all handles registered after this function call, otherwise it is disabled. By default, StarPU enables sequential data consistency. It is also possible to select the data consistency mode of a specific data handle with the function starpu_data_set_sequential_consistency_flag().

unsigned starpu_data_get_default_sequential_consistency_flag ( void  )

Return the default sequential consistency flag

void starpu_data_set_sequential_consistency_flag ( starpu_data_handle_t  handle,
unsigned  flag 
)

Set the data consistency mode associated to a data handle. The consistency mode set using this function has the priority over the default mode which can be set with starpu_data_set_default_sequential_consistency_flag().

Performance Feedback

Using The Temanejo Task Debugger

StarPU can connect to Temanejo >= 1.0rc2 (see http://www.hlrs.de/temanejo), to permit nice visual task debugging. To do so, build Temanejo's libayudame.so, install Ayudame.h to e.g. /usr/local/include, apply the tools/patch-ayudame to it to fix C build, re-./configure, make sure that it found it, rebuild StarPU. Run the Temanejo GUI, give it the path to your application, any options you want to pass it, the path to libayudame.so.

It permits to visualize the task graph, add breakpoints, continue execution task-by-task, and run gdb on a given task, etc.

temanejo.png

Make sure to specify at least the same number of CPUs in the dialog box as your machine has, otherwise an error will happen during execution. Future versions of Temanejo should be able to tell StarPU the number of CPUs to use.

Tag numbers have to be below 4000000000000000000ULL to be usable for Temanejo (so as to distinguish them from tasks).

On-line Performance Feedback

Enabling On-line Performance Monitoring

In order to enable online performance monitoring, the application can call starpu_profiling_status_set() with the parameter STARPU_PROFILING_ENABLE. It is possible to detect whether monitoring is already enabled or not by calling starpu_profiling_status_get(). Enabling monitoring also reinitialize all previously collected feedback. The environment variable STARPU_PROFILING can also be set to 1 to achieve the same effect. The function starpu_profiling_init() can also be called during the execution to reinitialize performance counters and to start the profiling if the environment variable STARPU_PROFILING is set to 1.

Likewise, performance monitoring is stopped by calling starpu_profiling_status_set() with the parameter STARPU_PROFILING_DISABLE. Note that this does not reset the performance counters so that the application may consult them later on.

More details about the performance monitoring API are available in Profiling.

Per-task Feedback

If profiling is enabled, a pointer to a structure starpu_profiling_task_info is put in the field starpu_task::profiling_info when a task terminates. This structure is automatically destroyed when the task structure is destroyed, either automatically or by calling starpu_task_destroy().

The structure starpu_profiling_task_info indicates the date when the task was submitted (starpu_profiling_task_info::submit_time), started (starpu_profiling_task_info::start_time), and terminated (starpu_profiling_task_info::end_time), relative to the initialization of StarPU with starpu_init(). It also specifies the identifier of the worker that has executed the task (starpu_profiling_task_info::workerid). These date are stored as timespec structures which the user may convert into micro-seconds using the helper function starpu_timing_timespec_to_us().

It it worth noting that the application may directly access this structure from the callback executed at the end of the task. The structure starpu_task associated to the callback currently being executed is indeed accessible with the function starpu_task_get_current().

Per-codelet Feedback

The field starpu_codelet::per_worker_stats is an array of counters. The i-th entry of the array is incremented every time a task implementing the codelet is executed on the i-th worker. This array is not reinitialized when profiling is enabled or disabled.

Per-worker Feedback

The second argument returned by the function starpu_profiling_worker_get_info() is a structure starpu_profiling_worker_info that gives statistics about the specified worker. This structure specifies when StarPU started collecting profiling information for that worker (starpu_profiling_worker_info::start_time), the duration of the profiling measurement interval (starpu_profiling_worker_info::total_time), the time spent executing kernels (starpu_profiling_worker_info::executing_time), the time spent sleeping because there is no task to execute at all (starpu_profiling_worker_info::sleeping_time), and the number of tasks that were executed while profiling was enabled. These values give an estimation of the proportion of time spent do real work, and the time spent either sleeping because there are not enough executable tasks or simply wasted in pure StarPU overhead.

Calling starpu_profiling_worker_get_info() resets the profiling information associated to a worker.

When an FxT trace is generated (see Generating Traces With FxT), it is also possible to use the tool starpu_workers_activity (see Monitoring Activity) to generate a graphic showing the evolution of these values during the time, for the different workers.

Bus-related Feedback

TODO: ajouter STARPU_BUS_STATS

The bus speed measured by StarPU can be displayed by using the tool starpu_machine_display, for instance:

StarPU-Top Interface

StarPU-Top is an interface which remotely displays the on-line state of a StarPU application and permits the user to change parameters on the fly.

Variables to be monitored can be registered by calling the functions starpu_top_add_data_boolean(), starpu_top_add_data_integer(), starpu_top_add_data_float(), e.g.:

starpu_top_data *data = starpu_top_add_data_integer("mynum", 0, 100, 1);

The application should then call starpu_top_init_and_wait() to give its name and wait for StarPU-Top to get a start request from the user. The name is used by StarPU-Top to quickly reload a previously-saved layout of parameter display.

starpu_top_init_and_wait("the application");

The new values can then be provided thanks to starpu_top_update_data_boolean(), starpu_top_update_data_integer(), starpu_top_update_data_float(), e.g.:

starpu_top_update_data_integer(data, mynum);

Updateable parameters can be registered thanks to starpu_top_register_parameter_boolean(), starpu_top_register_parameter_integer(), starpu_top_register_parameter_float(), e.g.:

float alpha;
starpu_top_register_parameter_float("alpha", &alpha, 0, 10, modif_hook);

modif_hook is a function which will be called when the parameter is being modified, it can for instance print the new value:

void modif_hook(struct starpu_top_param *d) {
fprintf(stderr,"%s has been modified: %f\n", d->name, alpha);
}

Task schedulers should notify StarPU-Top when it has decided when a task will be scheduled, so that it can show it in its Gantt chart, for instance:

starpu_top_task_prevision(task, workerid, begin, end);

Starting StarPU-Top (StarPU-Top is started via the binary starpu_top.) and the application can be done two ways:

  • The application is started by hand on some machine (and thus already waiting for the start event). In the Preference dialog of StarPU-Top, the SSH checkbox should be unchecked, and the hostname and port (default is 2011) on which the application is already running should be specified. Clicking on the connection button will thus connect to the already-running application.

  • StarPU-Top is started first, and clicking on the connection button will start the application itself (possibly on a remote machine). The SSH checkbox should be checked, and a command line provided, e.g.:

    $ ssh myserver STARPU_SCHED=dmda ./application

    If port 2011 of the remote machine can not be accessed directly, an ssh port bridge should be added:

    $ ssh -L 2011:localhost:2011 myserver STARPU_SCHED=dmda ./application

    and "localhost" should be used as IP Address to connect to.

Off-line Performance Feedback

Generating Traces With FxT

StarPU can use the FxT library (see https://savannah.nongnu.org/projects/fkt/) to generate traces with a limited runtime overhead.

You can either get a tarball:

$ wget http://download.savannah.gnu.org/releases/fkt/fxt-0.2.11.tar.gz

or use the FxT library from CVS (autotools are required):

$ cvs -d :pserver:anonymous\@cvs.sv.gnu.org:/sources/fkt co FxT
$ ./bootstrap

Compiling and installing the FxT library in the $FXTDIR path is done following the standard procedure:

$ ./configure --prefix=$FXTDIR
$ make
$ make install

In order to have StarPU to generate traces, StarPU should be configured with the option --with-fxt :

$ ./configure --with-fxt=$FXTDIR

Or you can simply point the PKG_CONFIG_PATH to $FXTDIR/lib/pkgconfig and pass --with-fxt to ./configure

When FxT is enabled, a trace is generated when StarPU is terminated by calling starpu_shutdown(). The trace is a binary file whose name has the form prof_file_XXX_YYY where XXX is the user name, and YYY is the pid of the process that used StarPU. This file is saved in the /tmp/ directory by default, or by the directory specified by the environment variable STARPU_FXT_PREFIX.

Creating a Gantt Diagram

When the FxT trace file filename has been generated, it is possible to generate a trace in the Paje format by calling:

$ starpu_fxt_tool -i filename

Or alternatively, setting the environment variable STARPU_GENERATE_TRACE to 1 before application execution will make StarPU do it automatically at application shutdown.

This will create a file paje.trace in the current directory that can be inspected with the ViTE trace visualizing open-source tool. It is possible to open the file paje.trace with ViTE by using the following command:

$ vite paje.trace

To get names of tasks instead of "unknown", fill the optional starpu_codelet::name, or use a performance model for them.

In the MPI execution case, collect the trace files from the MPI nodes, and specify them all on the command starpu_fxt_tool, for instance:

$ starpu_fxt_tool -i filename1 -i filename2

By default, all tasks are displayed using a green color. To display tasks with varying colors, pass option -c to starpu_fxt_tool.

Traces can also be inspected by hand by using the tool fxt_print, for instance:

$ fxt_print -o -f filename

Timings are in nanoseconds (while timings as seen in vite are in milliseconds).

Creating a DAG With Graphviz

When the FxT trace file filename has been generated, it is possible to generate a task graph in the DOT format by calling:

$ starpu_fxt_tool -i filename

This will create a dag.dot file in the current directory. This file is a task graph described using the DOT language. It is possible to get a graphical output of the graph by using the graphviz library:

$ dot -Tpdf dag.dot -o output.pdf

Monitoring Activity

When the FxT trace file filename has been generated, it is possible to generate an activity trace by calling:

$ starpu_fxt_tool -i filename

This will create a file activity.data in the current directory. A profile of the application showing the activity of StarPU during the execution of the program can be generated:

$ starpu_workers_activity activity.data

This will create a file named activity.eps in the current directory. This picture is composed of two parts. The first part shows the activity of the different workers. The green sections indicate which proportion of the time was spent executed kernels on the processing unit. The red sections indicate the proportion of time spent in StartPU: an important overhead may indicate that the granularity may be too low, and that bigger tasks may be appropriate to use the processing unit more efficiently. The black sections indicate that the processing unit was blocked because there was no task to process: this may indicate a lack of parallelism which may be alleviated by creating more tasks when it is possible.

The second part of the picture activity.eps is a graph showing the evolution of the number of tasks available in the system during the execution. Ready tasks are shown in black, and tasks that are submitted but not schedulable yet are shown in grey.

Performance Of Codelets

The performance model of codelets (see PerformanceModelExample) can be examined by using the tool starpu_perfmodel_display:

$ starpu_perfmodel_display -l
file: <malloc_pinned.hannibal>
file: <starpu_slu_lu_model_21.hannibal>
file: <starpu_slu_lu_model_11.hannibal>
file: <starpu_slu_lu_model_22.hannibal>
file: <starpu_slu_lu_model_12.hannibal>

Here, the codelets of the example lu are available. We can examine the performance of the kernel 22 (in micro-seconds), which is history-based:

$ starpu_perfmodel_display -s starpu_slu_lu_model_22
performance model for cpu
# hash      size       mean          dev           n
57618ab0    19660800   2.851069e+05  1.829369e+04  109
performance model for cuda_0
# hash      size       mean          dev           n
57618ab0    19660800   1.164144e+04  1.556094e+01  315
performance model for cuda_1
# hash      size       mean          dev           n
57618ab0    19660800   1.164271e+04  1.330628e+01  360
performance model for cuda_2
# hash      size       mean          dev           n
57618ab0    19660800   1.166730e+04  3.390395e+02  456

We can see that for the given size, over a sample of a few hundreds of execution, the GPUs are about 20 times faster than the CPUs (numbers are in us). The standard deviation is extremely low for the GPUs, and less than 10% for CPUs.

This tool can also be used for regression-based performance models. It will then display the regression formula, and in the case of non-linear regression, the same performance log as for history-based performance models:

$ starpu_perfmodel_display -s non_linear_memset_regression_based
performance model for cpu_impl_0
	Regression : #sample = 1400
	Linear: y = alpha size ^ beta
		alpha = 1.335973e-03
		beta = 8.024020e-01
	Non-Linear: y = a size ^b + c
		a = 5.429195e-04
		b = 8.654899e-01
		c = 9.009313e-01
# hash		size		mean		stddev		n
a3d3725e	4096           	4.763200e+00   	7.650928e-01   	100
870a30aa	8192           	1.827970e+00   	2.037181e-01   	100
48e988e9	16384          	2.652800e+00   	1.876459e-01   	100
961e65d2	32768          	4.255530e+00   	3.518025e-01   	100
...

The same can also be achieved by using StarPU's library API, see Performance Model and notably the function starpu_perfmodel_load_symbol(). The source code of the tool starpu_perfmodel_display can be a useful example.

The tool starpu_perfmodel_plot can be used to draw performance models. It writes a .gp file in the current directory, to be run with the tool gnuplot, which shows the corresponding curve.

starpu_non_linear_memset_regression_based.png

When the field starpu_task::flops is set, starpu_perfmodel_plot can directly draw a GFlops curve, by simply adding the -f option:

$ starpu_perfmodel_plot -f -s chol_model_11

This will however disable displaying the regression model, for which we can not compute GFlops.

starpu_chol_model_11_type.png

When the FxT trace file filename has been generated, it is possible to get a profiling of each codelet by calling:

$ starpu_fxt_tool -i filename
$ starpu_codelet_profile distrib.data codelet_name

This will create profiling data files, and a .gp file in the current directory, which draws the distribution of codelet time over the application execution, according to data input size.

distrib_data.png

This is also available in the tool starpu_perfmodel_plot, by passing it the fxt trace:

$ starpu_perfmodel_plot -s non_linear_memset_regression_based -i /tmp/prof_file_foo_0

It will produce a .gp file which contains both the performance model curves, and the profiling measurements.

starpu_non_linear_memset_regression_based_2.png

If you have the statistical tool R installed, you can additionally use

$ starpu_codelet_histo_profile distrib.data

Which will create one .pdf file per codelet and per input size, showing a histogram of the codelet execution time distribution.

distrib_data_histo.png

Trace statistics

More than just codelet performance, it is interesting to get statistics over all kinds of StarPU states (allocations, data transfers, etc.). This is particularly useful to check what may have gone wrong in the accurracy of the simgrid simulation.

This requires the R statistical tool, with the plyr, ggplot2 and data.table packages. If your system distribution does not have packages for these, one can fetch them from CRAN:

$ R
> install.packages("plyr")
> install.packages("ggplot2")
> install.packages("data.table")
> install.packages("knitr")

The pj_dump tool from pajeng is also needed (see https://github.com/schnorr/pajeng)

One can then get textual or .csv statistics over the trace states:

$ starpu_paje_state_stats -v native.trace simgrid.trace
"Value"         "Events_native.csv" "Duration_native.csv" "Events_simgrid.csv" "Duration_simgrid.csv"
"Callback"      220                 0.075978              220                  0
"chol_model_11" 10                  565.176               10                   572.8695
"chol_model_21" 45                  9184.828              45                   9170.719
"chol_model_22" 165                 64712.07              165                  64299.203
$ starpu_paje_state_stats native.trace simgrid.trace

And one can plot histograms of execution times, of several states for instance: 

$ starpu_paje_draw_histogram -n chol_model_11,chol_model_21,chol_model_22 native.trace simgrid.trace

and see the resulting pdf file:

paje_draw_histogram.png

A quick statistical report can be generated by using:

$ starpu_paje_summary native.trace simgrid.trace

it includes gantt charts, execution summaries, as well as state duration charts and time distribution histograms.

Other external Pajé analysis tools can be used on these traces, one just needs to sort the traces by timestamp order (which not guaranteed to make recording more efficient):

$ starpu_paje_sort paje.trace

Theoretical Lower Bound On Execution Time

StarPU can record a trace of what tasks are needed to complete the application, and then, by using a linear system, provide a theoretical lower bound of the execution time (i.e. with an ideal scheduling).

The computed bound is not really correct when not taking into account dependencies, but for an application which have enough parallelism, it is very near to the bound computed with dependencies enabled (which takes a huge lot more time to compute), and thus provides a good-enough estimation of the ideal execution time.

Theoretical Lower Bound On Execution Time Example provides an example on how to use this.

Memory Feedback

It is possible to enable memory statistics. To do so, you need to pass the option --enable-memory-stats when running configure. It is then possible to call the function starpu_data_display_memory_stats() to display statistics about the current data handles registered within StarPU.

Moreover, statistics will be displayed at the end of the execution on data handles which have not been cleared out. This can be disabled by setting the environment variable STARPU_MEMORY_STATS to 0.

For example, if you do not unregister data at the end of the complex example, you will get something similar to:

$ STARPU_MEMORY_STATS=0 ./examples/interface/complex
Complex[0] = 45.00 + 12.00 i
Complex[0] = 78.00 + 78.00 i
Complex[0] = 45.00 + 12.00 i
Complex[0] = 45.00 + 12.00 i

$ STARPU_MEMORY_STATS=1 ./examples/interface/complex
Complex[0] = 45.00 + 12.00 i
Complex[0] = 78.00 + 78.00 i
Complex[0] = 45.00 + 12.00 i
Complex[0] = 45.00 + 12.00 i

Data Statistics

Different data statistics can be displayed at the end of the execution of the application. To enable them, you need to pass the option --enable-stats when calling configure. When calling starpu_shutdown() various statistics will be displayed, execution, MSI cache statistics, allocation cache statistics, and data transfer statistics. The display can be disabled by setting the environment variable STARPU_STATS to 0.

Scheduling Context Hypervisor

What Is The Hypervisor

StarPU proposes a platform to construct Scheduling Contexts, to delete and modify them dynamically. A parallel kernel, can thus be isolated into a scheduling context and interferences between several parallel kernels are avoided. If the user knows exactly how many workers each scheduling context needs, he can assign them to the contexts at their creation time or modify them during the execution of the program.

The Scheduling Context Hypervisor Plugin is available for the users who do not dispose of a regular parallelism, who cannot know in advance the exact size of the context and need to resize the contexts according to the behavior of the parallel kernels.

The Hypervisor receives information from StarPU concerning the execution of the tasks, the efficiency of the resources, etc. and it decides accordingly when and how the contexts can be resized. Basic strategies of resizing scheduling contexts already exist but a platform for implementing additional custom ones is available.

Start the Hypervisor

The Hypervisor must be initialized once at the beginning of the application. At this point a resizing policy should be indicated. This strategy depends on the information the application is able to provide to the hypervisor as well as on the accuracy needed for the resizing procedure. For example, the application may be able to provide an estimation of the workload of the contexts. In this situation the hypervisor may decide what resources the contexts need. However, if no information is provided the hypervisor evaluates the behavior of the resources and of the application and makes a guess about the future. The hypervisor resizes only the registered contexts.

Interrogate The Runtime

The runtime provides the hypervisor with information concerning the behavior of the resources and the application. This is done by using the performance_counters which represent callbacks indicating when the resources are idle or not efficient, when the application submits tasks or when it becomes to slow.

Trigger the Hypervisor

The resizing is triggered either when the application requires it ( sc_hypervisor_resize_ctxs ) or when the initials distribution of resources alters the performance of the application (the application is to slow or the resource are idle for too long time). If the environment variable SC_HYPERVISOR_TRIGGER_RESIZE is set to speed the monitored speed of the contexts is compared to a theoretical value computed with a linear program, and the resizing is triggered whenever the two values do not correspond. Otherwise, if the environment variable is set to idle the hypervisor triggers the resizing algorithm whenever the workers are idle for a period longer than the threshold indicated by the programmer. When this happens different resizing strategy are applied that target minimizing the total execution of the application, the instant speed or the idle time of the resources.

Resizing Strategies

The plugin proposes several strategies for resizing the scheduling context.

The Application driven strategy uses the user's input concerning the moment when he wants to resize the contexts. Thus, the users tags the task that should trigger the resizing process. We can set directly the field starpu_task::hypervisor_tag or use the macro ::STARPU_HYPERVISOR_TAG in the function starpu_insert_task().

task.hypervisor_tag = 2;

or

starpu_insert_task(&codelet,
...,
STARPU_HYPERVISOR_TAG, 2,
0);

Then the user has to indicate that when a task with the specified tag is executed the contexts should resize.

sc_hypervisor_resize(sched_ctx, 2);

The user can use the same tag to change the resizing configuration of the contexts if he considers it necessary.

sc_hypervisor_ctl(sched_ctx,
SC_HYPERVISOR_MIN_WORKERS, 6,
SC_HYPERVISOR_MAX_WORKERS, 12,
SC_HYPERVISOR_TIME_TO_APPLY, 2,
NULL);

The Idleness based strategy moves workers unused in a certain context to another one needing them. (see Users’ Input In The Resizing Process)

int workerids[3] = {1, 3, 10};
int workerids2[9] = {0, 2, 4, 5, 6, 7, 8, 9, 11};
sc_hypervisor_ctl(sched_ctx_id,
SC_HYPERVISOR_MAX_IDLE, workerids, 3, 10000.0,
SC_HYPERVISOR_MAX_IDLE, workerids2, 9, 50000.0,
NULL);

The Gflops rate based strategy resizes the scheduling contexts such that they all finish at the same time. The speed of each of them is computed and once one of them is significantly slower the resizing process is triggered. In order to do these computations the user has to input the total number of instructions needed to be executed by the parallel kernels and the number of instruction to be executed by each task.

The number of flops to be executed by a context are passed as parameter when they are registered to the hypervisor, (sc_hypervisor_register_ctx(sched_ctx_id, flops)) and the one to be executed by each task are passed when the task is submitted. The corresponding field is starpu_task::flops and the corresponding macro in the function starpu_insert_task() is STARPU_FLOPS (Caution: but take care of passing a double, not an integer, otherwise parameter passing will be bogus). When the task is executed the resizing process is triggered.

task.flops = 100;

or

starpu_insert_task(&codelet,
...,
STARPU_FLOPS, (double) 100,
0);

The Feft strategy uses a linear program to predict the best distribution of resources such that the application finishes in a minimum amount of time. As for the Gflops rate strategy the programmers has to indicate the total number of flops to be executed when registering the context. This number of flops may be updated dynamically during the execution of the application whenever this information is not very accurate from the beginning. The function sc_hypervisor_update_diff_total_flop is called in order add or remove a difference to the flops left to be executed. Tasks are provided also the number of flops corresponding to each one of them. During the execution of the application the hypervisor monitors the consumed flops and recomputes the time left and the number of resources to use. The speed of each type of resource is (re)evaluated and inserter in the linear program in order to better adapt to the needs of the application.

The Teft strategy uses a linear program too, that considers all the types of tasks and the number of each of them and it tries to allocates resources such that the application finishes in a minimum amount of time. A previous calibration of StarPU would be useful in order to have good predictions of the execution time of each type of task.

The types of tasks may be determines directly by the hypervisor when they are submitted. However there are applications that do not expose all the graph of tasks from the beginning. In this case in order to let the hypervisor know about all the tasks the function sc_hypervisor_set_type_of_task will just inform the hypervisor about future tasks without submitting them right away.

The Ispeed strategy divides the execution of the application in several frames. For each frame the hypervisor computes the speed of the contexts and tries making them run at the same speed. The strategy requires less contribution from the user as the hypervisor requires only the size of the frame in terms of flops.

int workerids[3] = {1, 3, 10};
int workerids2[9] = {0, 2, 4, 5, 6, 7, 8, 9, 11};
sc_hypervisor_ctl(sched_ctx_id,
SC_HYPERVISOR_ISPEED_W_SAMPLE, workerids, 3, 2000000000.0,
SC_HYPERVISOR_ISPEED_W_SAMPLE, workerids2, 9, 200000000000.0,
SC_HYPERVISOR_ISPEED_CTX_SAMPLE, 60000000000.0,
NULL);

The Throughput strategy focuses on maximizing the throughput of the resources and resizes the contexts such that the machine is running at its maximum efficiency (maximum instant speed of the workers).

a new hypervisor policy

While Scheduling Context Hypervisor Plugin comes with a variety of resizing policies (see Resizing Strategies), it may sometimes be desirable to implement custom policies to address specific problems. The API described below allows users to write their own resizing policy.

Here an example of how to define a new policy

struct sc_hypervisor_policy dummy_policy =
{
.handle_poped_task = dummy_handle_poped_task,
.handle_pushed_task = dummy_handle_pushed_task,
.handle_idle_cycle = dummy_handle_idle_cycle,
.handle_idle_end = dummy_handle_idle_end,
.handle_post_exec_hook = dummy_handle_post_exec_hook,
.custom = 1,
.name = "dummy"
};

Basic Data Management API

Data management is done at a high-level in StarPU: rather than accessing a mere list of contiguous buffers, the tasks may manipulate data that are described by a high-level construct which we call data interface.

An example of data interface is the "vector" interface which describes a contiguous data array on a spefic memory node. This interface is a simple structure containing the number of elements in the array, the size of the elements, and the address of the array in the appropriate address space (this address may be invalid if there is no valid copy of the array in the memory node). More informations on the data interfaces provided by StarPU are given in Data Interfaces.

When a piece of data managed by StarPU is used by a task, the task implementation is given a pointer to an interface describing a valid copy of the data that is accessible from the current processing unit.

Every worker is associated to a memory node which is a logical abstraction of the address space from which the processing unit gets its data. For instance, the memory node associated to the different CPU workers represents main memory (RAM), the memory node associated to a GPU is DRAM embedded on the device. Every memory node is identified by a logical index which is accessible from the function starpu_worker_get_memory_node(). When registering a piece of data to StarPU, the specified memory node indicates where the piece of data initially resides (we also call this memory node the home node of a piece of data).

void starpu_data_register (starpu_data_handle_t *handleptr, unsigned home_node, void *data_interface, struct starpu_data_interface_ops *ops)

C Extensions

When GCC plug-in support is available, StarPU builds a plug-in for the GNU Compiler Collection (GCC), which defines extensions to languages of the C family (C, C++, Objective-C) that make it easier to write StarPU code. This feature is only available for GCC 4.5 and later; it is known to work with GCC 4.5, 4.6, and 4.7. You may need to install a specific -dev package of your distro, such as gcc-4.6-plugin-dev on Debian and derivatives. In addition, the plug-in's test suite is only run when GNU Guile is found at configure-time. Building the GCC plug-in can be disabled by configuring with --disable-gcc-extensions.

Those extensions include syntactic sugar for defining tasks and their implementations, invoking a task, and manipulating data buffers. Use of these extensions can be made conditional on the availability of the plug-in, leading to valid C sequential code when the plug-in is not used (Using C Extensions Conditionally).

When StarPU has been installed with its GCC plug-in, programs that use these extensions can be compiled this way:

$ gcc -c -fplugin=`pkg-config starpu-1.1 --variable=gccplugin` foo.c

When the plug-in is not available, the above pkg-config command returns the empty string.

In addition, the -fplugin-arg-starpu-verbose flag can be used to obtain feedback from the compiler as it analyzes the C extensions used in source files.

This section describes the C extensions implemented by StarPU's GCC plug-in. It does not require detailed knowledge of the StarPU library.

Note: this is still an area under development and subject to change.

Defining Tasks

The StarPU GCC plug-in views tasks as ``extended'' C functions:

  • tasks may have several implementations—e.g., one for CPUs, one written in OpenCL, one written in CUDA;
  • tasks may have several implementations of the same target—e.g., several CPU implementations;
  • when a task is invoked, it may run in parallel, and StarPU is free to choose any of its implementations.

Tasks and their implementations must be declared. These declarations are annotated with attributes (http://gcc.gnu.org/onlinedocs/gcc/Attribute-Syntax.html#Attribute-Syntax): the declaration of a task is a regular C function declaration with an additional task attribute, and task implementations are declared with a task_implementation attribute.

The following function attributes are provided:

task

Declare the given function as a StarPU task. Its return type must be void. When a function declared as task has a user-defined body, that body is interpreted as the implicit definition of the task's CPU implementation (see example below). In all cases, the actual definition of a task's body is automatically generated by the compiler.

Under the hood, declaring a task leads to the declaration of the corresponding codelet (Codelet and Tasks). If one or more task implementations are declared in the same compilation unit, then the codelet and the function itself are also defined; they inherit the scope of the task.

Scalar arguments to the task are passed by value and copied to the target device if need be—technically, they are passed as the buffer starpu_task::cl_arg (Codelet and Tasks).

Pointer arguments are assumed to be registered data buffers—the handles argument of a task (starpu_task::handles) ; const-qualified pointer arguments are viewed as read-only buffers (STARPU_R), and non-const-qualified buffers are assumed to be used read-write (STARPU_RW). In addition, the output type attribute can be as a type qualifier for output pointer or array parameters (STARPU_W).

task_implementation (target, task)

Declare the given function as an implementation of task to run on target. target must be a string, currently one of "cpu", "opencl", or "cuda".

Here is an example:

#define __output __attribute__ ((output))
static void matmul (const float *A, const float *B,
__output float *C,
unsigned nx, unsigned ny, unsigned nz)
__attribute__ ((task));
static void matmul_cpu (const float *A, const float *B,
__output float *C,
unsigned nx, unsigned ny, unsigned nz)
__attribute__ ((task_implementation ("cpu", matmul)));
static void
matmul_cpu (const float *A, const float *B, __output float *C,
unsigned nx, unsigned ny, unsigned nz)
{
unsigned i, j, k;
for (j = 0; j < ny; j++)
for (i = 0; i < nx; i++)
{
for (k = 0; k < nz; k++)
C[j * nx + i] += A[j * nz + k] * B[k * nx + i];
}
}

A matmult task is defined; it has only one implementation, matmult_cpu, which runs on the CPU. Variables A and B are input buffers, whereas C is considered an input/output buffer.

For convenience, when a function declared with the task attribute has a user-defined body, that body is assumed to be that of the CPU implementation of a task, which we call an implicit task CPU implementation. Thus, the above snippet can be simplified like this:

#define __output __attribute__ ((output))
static void matmul (const float *A, const float *B,
__output float *C,
unsigned nx, unsigned ny, unsigned nz)
__attribute__ ((task));
/* Implicit definition of the CPU implementation of the
`matmul' task. */
static void
matmul (const float *A, const float *B, __output float *C,
unsigned nx, unsigned ny, unsigned nz)
{
unsigned i, j, k;
for (j = 0; j < ny; j++)
for (i = 0; i < nx; i++)
{
for (k = 0; k < nz; k++)
C[j * nx + i] += A[j * nz + k] * B[k * nx + i];
}
}

Use of implicit CPU task implementations as above has the advantage that the code is valid sequential code when StarPU's GCC plug-in is not used (Using C Extensions Conditionally).

CUDA and OpenCL implementations can be declared in a similar way:

static void matmul_cuda (const float *A, const float *B, float *C,
unsigned nx, unsigned ny, unsigned nz)
__attribute__ ((task_implementation ("cuda", matmul)));
static void matmul_opencl (const float *A, const float *B, float *C,
unsigned nx, unsigned ny, unsigned nz)
__attribute__ ((task_implementation ("opencl", matmul)));

The CUDA and OpenCL implementations typically either invoke a kernel written in CUDA or OpenCL (for similar code, CUDA Kernel, and OpenCL Kernel), or call a library function that uses CUDA or OpenCL under the hood, such as CUBLAS functions:

static void
matmul_cuda (const float *A, const float *B, float *C,
unsigned nx, unsigned ny, unsigned nz)
{
cublasSgemm ('n', 'n', nx, ny, nz,
1.0f, A, 0, B, 0,
0.0f, C, 0);
cudaStreamSynchronize (starpu_cuda_get_local_stream ());
}

A task can be invoked like a regular C function:

matmul (&A[i * zdim * bydim + k * bzdim * bydim],
&B[k * xdim * bzdim + j * bxdim * bzdim],
&C[i * xdim * bydim + j * bxdim * bydim],
bxdim, bydim, bzdim);

This leads to an asynchronous invocation, whereby matmult's implementation may run in parallel with the continuation of the caller.

The next section describes how memory buffers must be handled in StarPU-GCC code. For a complete example, see the gcc-plugin/examples directory of the source distribution, and Vector Scaling Using the C Extension.

Initialization, Termination, and Synchronization

The following pragmas allow user code to control StarPU's life time and to synchronize with tasks.

#pragma starpu initialize

Initialize StarPU. This call is compulsory and is never added implicitly. One of the reasons this has to be done explicitly is that it provides greater control to user code over its resource usage.

#pragma starpu shutdown

Shut down StarPU, giving it an opportunity to write profiling info to a file on disk, for instance (Off-line Performance Feedback).

#pragma starpu wait
Wait for all task invocations to complete, as with starpu_task_wait_for_all().

Registered Data Buffers

Data buffers such as matrices and vectors that are to be passed to tasks must be registered. Registration allows StarPU to handle data transfers among devices—e.g., transferring an input buffer from the CPU's main memory to a task scheduled to run a GPU (StarPU Data Management Library).

The following pragmas are provided:

#pragma starpu register ptr [size]

Register ptr as a size-element buffer. When ptr has an array type whose size is known, size may be omitted. Alternatively, the registered attribute can be used (see below.)

#pragma starpu unregister ptr

Unregister the previously-registered memory area pointed to by ptr. As a side-effect, ptr points to a valid copy in main memory.

#pragma starpu acquire ptr

Acquire in main memory an up-to-date copy of the previously-registered memory area pointed to by ptr, for read-write access.

#pragma starpu release ptr
Release the previously-register memory area pointed to by ptr, making it available to the tasks.

Additionally, the following attributes offer a simple way to allocate and register storage for arrays:

registered

This attributes applies to local variables with an array type. Its effect is to automatically register the array's storage, as per #pragma starpu register. The array is automatically unregistered when the variable's scope is left. This attribute is typically used in conjunction with the heap_allocated attribute, described below.

heap_allocated
This attributes applies to local variables with an array type. Its effect is to automatically allocate the array's storage on the heap, using starpu_malloc() under the hood. The heap-allocated array is automatically freed when the variable's scope is left, as with automatic variables.

The following example illustrates use of the heap_allocated attribute:

extern void cholesky(unsigned nblocks, unsigned size,
float mat[nblocks][nblocks][size])
__attribute__ ((task));
int
main (int argc, char *argv[])
{
#pragma starpu initialize
/* ... */
int nblocks, size;
parse_args (&nblocks, &size);
/* Allocate an array of the required size on the heap,
and register it. */
{
float matrix[nblocks][nblocks][size]
__attribute__ ((heap_allocated, registered));
cholesky (nblocks, size, matrix);
#pragma starpu wait
} /* MATRIX is automatically unregistered & freed here. */
#pragma starpu shutdown
return EXIT_SUCCESS;
}

Using C Extensions Conditionally

The C extensions described in this chapter are only available when GCC and its StarPU plug-in are in use. Yet, it is possible to make use of these extensions when they are available—leading to hybrid CPU/GPU code—and discard them when they are not available—leading to valid sequential code.

To that end, the GCC plug-in defines the C preprocessor macro — STARPU_GCC_PLUGIN — when it is being used. When defined, this macro expands to an integer denoting the version of the supported C extensions.

The code below illustrates how to define a task and its implementations in a way that allows it to be compiled without the GCC plug-in:

/* This program is valid, whether or not StarPU's GCC plug-in
is being used. */
#include <stdlib.h>
/* The attribute below is ignored when GCC is not used. */
static void matmul (const float *A, const float *B, float * C,
unsigned nx, unsigned ny, unsigned nz)
__attribute__ ((task));
static void
matmul (const float *A, const float *B, float * C,
unsigned nx, unsigned ny, unsigned nz)
{
/* Code of the CPU kernel here... */
}
#ifdef STARPU_GCC_PLUGIN
/* Optional OpenCL task implementation. */
static void matmul_opencl (const float *A, const float *B, float * C,
unsigned nx, unsigned ny, unsigned nz)
__attribute__ ((task_implementation ("opencl", matmul)));
static void
matmul_opencl (const float *A, const float *B, float * C,
unsigned nx, unsigned ny, unsigned nz)
{
/* Code that invokes the OpenCL kernel here... */
}
#endif
int
main (int argc, char *argv[])
{
/* The pragmas below are simply ignored when StarPU-GCC
is not used. */
#pragma starpu initialize
float A[123][42][7], B[123][42][7], C[123][42][7];
#pragma starpu register A
#pragma starpu register B
#pragma starpu register C
/* When StarPU-GCC is used, the call below is asynchronous;
otherwise, it is synchronous. */
matmul ((float *) A, (float *) B, (float *) C, 123, 42, 7);
#pragma starpu wait
#pragma starpu shutdown
return EXIT_SUCCESS;
}

The above program is a valid StarPU program when StarPU's GCC plug-in is used; it is also a valid sequential program when the plug-in is not used.

Note that attributes such as task as well as starpu pragmas are simply ignored by GCC when the StarPU plug-in is not loaded. However, gcc -Wall emits a warning for unknown attributes and pragmas, which can be inconvenient. In addition, other compilers may be unable to parse the attribute syntax (In practice, Clang and several proprietary compilers implement attributes.), so you may want to wrap attributes in macros like this:

/* Use the `task' attribute only when StarPU's GCC plug-in
is available. */
#ifdef STARPU_GCC_PLUGIN
# define __task __attribute__ ((task))
#else
# define __task
#endif
static void matmul (const float *A, const float *B, float *C,
unsigned nx, unsigned ny, unsigned nz) __task;

Detailed Description

Data Structure Documentation

struct starpu_worker_collection

A scheduling context manages a collection of workers that can be memorized using different data structures. Thus, a generic structure is available in order to simplify the choice of its type. Only the list data structure is available but further data structures(like tree) implementations are foreseen.

Function Documentation

unsigned starpu_worker_get_count ( void  )

This function returns the number of workers (i.e. processing units executing StarPU tasks). The returned value should be at most STARPU_NMAXWORKERS.

int starpu_worker_get_count_by_type ( enum starpu_worker_archtype  type)

Returns the number of workers of the given type. A positive (or NULL) value is returned in case of success, -EINVAL indicates that the type is not valid otherwise.

unsigned starpu_cpu_worker_get_count ( void  )

This function returns the number of CPUs controlled by StarPU. The returned value should be at most STARPU_MAXCPUS.

unsigned starpu_cuda_worker_get_count ( void  )

This function returns the number of CUDA devices controlled by StarPU. The returned value should be at most STARPU_MAXCUDADEVS.

unsigned starpu_opencl_worker_get_count ( void  )

This function returns the number of OpenCL devices controlled by StarPU. The returned value should be at most STARPU_MAXOPENCLDEVS.

int starpu_worker_get_id ( void  )

This function returns the identifier of the current worker, i.e the one associated to the calling thread. The returned value is either -1 if the current context is not a StarPU worker (i.e. when called from the application outside a task or a callback), or an integer between 0 and starpu_worker_get_count() - 1.

int starpu_worker_get_ids_by_type ( enum starpu_worker_archtype  type,
int *  workerids,
int  maxsize 
)

This function gets the list of identifiers of workers with the given type. It fills the array workerids with the identifiers of the workers that have the type indicated in the first argument. The argument maxsize indicates the size of the array workerids. The returned value gives the number of identifiers that were put in the array. -ERANGE is returned is maxsize is lower than the number of workers with the appropriate type: in that case, the array is filled with the maxsize first elements. To avoid such overflows, the value of maxsize can be chosen by the means of the function starpu_worker_get_count_by_type(), or by passing a value greater or equal to STARPU_NMAXWORKERS.

int starpu_worker_get_by_type ( enum starpu_worker_archtype  type,
int  num 
)

This returns the identifier of the num-th worker that has the specified type type. If there are no such worker, -1 is returned.

int starpu_worker_get_by_devid ( enum starpu_worker_archtype  type,
int  devid 
)

This returns the identifier of the worker that has the specified type type and device id devid (which may not be the n-th, if some devices are skipped for instance). If there are no such worker, -1 is returned.

int starpu_worker_get_devid ( int  id)

This function returns the device id of the given worker. The worker should be identified with the value returned by the starpu_worker_get_id() function. In the case of a CUDA worker, this device identifier is the logical device identifier exposed by CUDA (used by the function cudaGetDevice() for instance). The device identifier of a CPU worker is the logical identifier of the core on which the worker was bound; this identifier is either provided by the OS or by the library hwloc in case it is available.

enum starpu_worker_archtype starpu_worker_get_type ( int  id)

This function returns the type of processing unit associated to a worker. The worker identifier is a value returned by the function starpu_worker_get_id()). The returned value indicates the architecture of the worker: STARPU_CPU_WORKER for a CPU core, STARPU_CUDA_WORKER for a CUDA device, and STARPU_OPENCL_WORKER for a OpenCL device. The value returned for an invalid identifier is unspecified.

void starpu_worker_get_name ( int  id,
char *  dst,
size_t  maxlen 
)

This function allows to get the name of a given worker. StarPU associates a unique human readable string to each processing unit. This function copies at most the maxlen first bytes of the unique string associated to a worker identified by its identifier id into the dst buffer. The caller is responsible for ensuring that dst is a valid pointer to a buffer of maxlen bytes at least. Calling this function on an invalid identifier results in an unspecified behaviour.

unsigned starpu_worker_get_memory_node ( unsigned  workerid)

This function returns the identifier of the memory node associated to the worker identified by workerid.

enum starpu_node_kind starpu_node_get_kind ( unsigned  node)

Returns the type of the given node as defined by starpu_node_kind. For example, when defining a new data interface, this function should be used in the allocation function to determine on which device the memory needs to be allocated.

Function Documentation

int starpu_pthread_create ( starpu_pthread_t *  thread,
const starpu_pthread_attr_t *  attr,
void *(*)(void *)  start_routine,
void *  arg 
)

This function starts a new thread in the calling process. The new thread starts execution by invoking start_routine; arg is passed as the sole argument of start_routine.

int starpu_pthread_join ( starpu_pthread_t  thread,
void **  retval 
)

This function waits for the thread specified by thread to terminate. If that thread has already terminated, then the function returns immediately. The thread specified by thread must be joinable.

int starpu_pthread_attr_init ( starpu_pthread_attr_t *  attr)

This function initializes the thread attributes object pointed to by attr with default attribute values.

It does not do anything when the simulated performance mode is enabled (Simulated Performance).

int starpu_pthread_attr_destroy ( starpu_pthread_attr_t *  attr)

This function destroys a thread attributes object which is no longer required. Destroying a thread attributes object has no effect on threads that were created using that object.

It does not do anything when the simulated performance mode is enabled (Simulated Performance).

int starpu_pthread_attr_setdetachstate ( starpu_pthread_attr_t *  attr,
int  detachstate 
)

This function sets the detach state attribute of the thread attributes object referred to by attr to the value specified in detachstate. The detach state attribute determines whether a thread created using the thread attributes object attr will be created in a joinable or a detached state.

It does not do anything when the simulated performance mode is enabled (Simulated Performance).

int starpu_pthread_mutex_init ( starpu_pthread_mutex_t *  mutex,
const starpu_pthread_mutexattr_t *  mutexattr 
)

This function initializes the mutex object pointed to by mutex according to the mutex attributes specified in mutexattr. If mutexattr is NULL, default attributes are used instead.

int starpu_pthread_mutex_destroy ( starpu_pthread_mutex_t *  mutex)

This function destroys a mutex object, freeing the resources it might hold. The mutex must be unlocked on entrance.

int starpu_pthread_mutex_lock ( starpu_pthread_mutex_t *  mutex)

This function locks the given mutex. If the mutex is currently unlocked, it becomes locked and owned by the calling thread, and the function returns immediately. If the mutex is already locked by another thread, the function suspends the calling thread until the mutex is unlocked.

int starpu_pthread_mutex_unlock ( starpu_pthread_mutex_t *  mutex)

This function unlocks the given mutex. The mutex is assumed to be locked and owned by the calling thread on entrance to starpu_pthread_mutex_unlock().

int starpu_pthread_mutex_trylock ( starpu_pthread_mutex_t *  mutex)

This function behaves identically to starpu_pthread_mutex_lock(), except that it does not block the calling thread if the mutex is already locked by another thread (or by the calling thread in the case of a ``fast'' mutex). Instead, the function returns immediately with the error code EBUSY.

int starpu_pthread_key_create ( starpu_pthread_key_t *  key,
void(*)(void *)  destr_function 
)

This function allocates a new TSD key. The key is stored in the location pointed to by key.

int starpu_pthread_key_delete ( starpu_pthread_key_t  key)

This function deallocates a TSD key. It does not check whether non-NULL values are associated with that key in the currently executing threads, nor call the destructor function associated with the key.

int starpu_pthread_setspecific ( starpu_pthread_key_t  key,
const void *  pointer 
)

This function changes the value associated with key in the calling thread, storing the given pointer instead.

* starpu_pthread_getspecific ( starpu_pthread_key_t  key)

This function returns the value associated with key on success, and NULL on error.

starpu_pthread_cond_init ( starpu_pthread_cond_t *  cond,
starpu_pthread_condattr_t *  cond_attr 
)

This function initializes the condition variable cond, using the condition attributes specified in cond_attr, or default attributes if cond_attr is NULL.

starpu_pthread_cond_signal ( starpu_pthread_cond_t *  cond)

This function restarts one of the threads that are waiting on the condition variable cond. If no threads are waiting on cond, nothing happens. If several threads are waiting on cond, exactly one is restarted, but it not specified which.

starpu_pthread_cond_broadcast ( starpu_pthread_cond_t *  cond)

This function restarts all the threads that are waiting on the condition variable cond. Nothing happens if no threads are waiting on cond.

starpu_pthread_cond_wait ( starpu_pthread_cond_t *  cond,
starpu_pthread_mutex_t *  mutex 
)

This function atomically unlocks the mutex (as per starpu_pthread_mutex_unlock()) and waits for the condition variable cond to be signaled. The thread execution is suspended and does not consume any CPU time until the condition variable is signaled. The mutex must be locked by the calling thread on entrance to starpu_pthread_cond_wait(). Before returning to the calling thread, the function re-acquires mutex (as per starpu_pthread_mutex_lock()).

starpu_pthread_cond_timedwait ( starpu_pthread_cond_t *  cond,
starpu_pthread_mutex_t *  mutex,
const struct timespec *  abstime 
)

This function atomically unlocks mutex and waits on cond, as starpu_pthread_cond_wait() does, but it also bounds the duration of the wait.

starpu_pthread_cond_destroy ( starpu_pthread_cond_t *  cond)

This function destroys a condition variable, freeing the resources it might hold. No threads must be waiting on the condition variable on entrance to the function.

starpu_pthread_rwlock_init ( starpu_pthread_rwlock_t *  rwlock,
const starpu_pthread_rwlockattr_t *  attr 
)

This function is the same as starpu_pthread_mutex_init().

starpu_pthread_rwlock_destroy ( starpu_pthread_rwlock_t *  rwlock)

This function is the same as starpu_pthread_mutex_destroy().

starpu_pthread_rwlock_rdlock ( starpu_pthread_rwlock_t *  rwlock)

This function is the same as starpu_pthread_mutex_lock().

starpu_pthread_rwlock_wrlock ( starpu_pthread_rwlock_t *  rwlock)

This function is the same as starpu_pthread_mutex_lock().

starpu_pthread_rwlock_unlock ( starpu_pthread_rwlock_t *  rwlock)

This function is the same as starpu_pthread_mutex_unlock().

Basic Data Management API

Data management is done at a high-level in StarPU: rather than accessing a mere list of contiguous buffers, the tasks may manipulate data that are described by a high-level construct which we call data interface.

An example of data interface is the "vector" interface which describes a contiguous data array on a spefic memory node. This interface is a simple structure containing the number of elements in the array, the size of the elements, and the address of the array in the appropriate address space (this address may be invalid if there is no valid copy of the array in the memory node). More informations on the data interfaces provided by StarPU are given in Data Interfaces.

When a piece of data managed by StarPU is used by a task, the task implementation is given a pointer to an interface describing a valid copy of the data that is accessible from the current processing unit.

Every worker is associated to a memory node which is a logical abstraction of the address space from which the processing unit gets its data. For instance, the memory node associated to the different CPU workers represents main memory (RAM), the memory node associated to a GPU is DRAM embedded on the device. Every memory node is identified by a logical index which is accessible from the function starpu_worker_get_memory_node(). When registering a piece of data to StarPU, the specified memory node indicates where the piece of data initially resides (we also call this memory node the home node of a piece of data).

Detailed Description

This section describes the data management facilities provided by StarPU. We show how to use existing data interfaces in Data Interfaces, but developers can design their own data interfaces if required.

Macro Definition Documentation

#define STARPU_DATA_ACQUIRE_CB (   handle,
  mode,
  code 
)

STARPU_DATA_ACQUIRE_CB() is the same as starpu_data_acquire_cb(), except that the code to be executed in a callback is directly provided as a macro parameter, and the data handle is automatically released after it. This permits to easily execute code which depends on the value of some registered data. This is non-blocking too and may be called from task callbacks.

Typedef Documentation

starpu_data_handle_t

StarPU uses starpu_data_handle_t as an opaque handle to manage a piece of data. Once a piece of data has been registered to StarPU, it is associated to a starpu_data_handle_t which keeps track of the state of the piece of data over the entire machine, so that we can maintain data consistency and locate data replicates for instance.

Enumeration Type Documentation

enum starpu_data_access_mode

This datatype describes a data access mode.

Enumerator:
STARPU_NONE 

TODO

STARPU_R 

read-only mode.

STARPU_W 

write-only mode.

STARPU_RW 

read-write mode. This is equivalent to STARPU_R|STARPU_W

STARPU_SCRATCH 

A temporary buffer is allocated for the task, but StarPU does not enforce data consistency—i.e. each device has its own buffer, independently from each other (even for CPUs), and no data transfer is ever performed. This is useful for temporary variables to avoid allocating/freeing buffers inside each task. Currently, no behavior is defined concerning the relation with the STARPU_R and STARPU_W modes and the value provided at registration — i.e., the value of the scratch buffer is undefined at entry of the codelet function. It is being considered for future extensions at least to define the initial value. For now, data to be used in STARPU_SCRATCH mode should be registered with node -1 and a NULL pointer, since the value of the provided buffer is simply ignored for now.

STARPU_REDUX 

todo

STARPU_SSEND 

used in starpu_mpi_insert_task() to specify the data has to be sent using a synchronous and non-blocking mode (see starpu_mpi_issend())

Function Documentation

void starpu_data_register ( starpu_data_handle_t *  handleptr,
unsigned  home_node,
void *  data_interface,
struct starpu_data_interface_ops *  ops 
)

Register a piece of data into the handle located at the handleptr address. The data_interface buffer contains the initial description of the data in the home_node. The ops argument is a pointer to a structure describing the different methods used to manipulate this type of interface. See starpu_data_interface_ops for more details on this structure. If home_node is -1, StarPU will automatically allocate the memory when it is used for the first time in write-only mode. Once such data handle has been automatically allocated, it is possible to access it using any access mode. Note that StarPU supplies a set of predefined types of interface (e.g. vector or matrix) which can be registered by the means of helper functions (e.g. starpu_vector_data_register() or starpu_matrix_data_register()).

void starpu_data_ptr_register ( starpu_data_handle_t  handle,
unsigned  node 
)

Register that a buffer for handle on node will be set. This is typically used by starpu_*_ptr_register helpers before setting the interface pointers for this node, to tell the core that that is now allocated.

void starpu_data_register_same ( starpu_data_handle_t *  handledst,
starpu_data_handle_t  handlesrc 
)

Register a new piece of data into the handle handledst with the same interface as the handle handlesrc.

void starpu_data_unregister ( starpu_data_handle_t  handle)

This function unregisters a data handle from StarPU. If the data was automatically allocated by StarPU because the home node was -1, all automatically allocated buffers are freed. Otherwise, a valid copy of the data is put back into the home node in the buffer that was initially registered. Using a data handle that has been unregistered from StarPU results in an undefined behaviour. In case we do not need to update the value of the data in the home node, we can use the function starpu_data_unregister_no_coherency() instead.

void starpu_data_unregister_no_coherency ( starpu_data_handle_t  handle)

This is the same as starpu_data_unregister(), except that StarPU does not put back a valid copy into the home node, in the buffer that was initially registered.

void starpu_data_unregister_submit ( starpu_data_handle_t  handle)

Destroy the data handle once it is not needed anymore by any submitted task. No coherency is assumed.

void starpu_data_invalidate ( starpu_data_handle_t  handle)

Destroy all replicates of the data handle immediately. After data invalidation, the first access to the handle must be performed in write-only mode. Accessing an invalidated data in read-mode results in undefined behaviour.

void starpu_data_invalidate_submit ( starpu_data_handle_t  handle)

Submits invalidation of the data handle after completion of previously submitted tasks.

void starpu_data_set_wt_mask ( starpu_data_handle_t  handle,
uint32_t  wt_mask 
)

This function sets the write-through mask of a given data (and its children), i.e. a bitmask of nodes where the data should be always replicated after modification. It also prevents the data from being evicted from these nodes when memory gets scarse. When the data is modified, it is automatically transfered into those memory node. For instance a 1<<0 write-through mask means that the CUDA workers will commit their changes in main memory (node 0).

int starpu_data_prefetch_on_node ( starpu_data_handle_t  handle,
unsigned  node,
unsigned  async 
)

Issue a prefetch request for a given data to a given node, i.e. requests that the data be replicated to the given node, so that it is available there for tasks. If the async parameter is 0, the call will block until the transfer is achieved, else the call will return immediately, after having just queued the request. In the latter case, the request will asynchronously wait for the completion of any task writing on the data.

starpu_data_handle_t starpu_data_lookup ( const void *  ptr)

Return the handle corresponding to the data pointed to by the ptr host pointer.

int starpu_data_request_allocation ( starpu_data_handle_t  handle,
unsigned  node 
)

Explicitly ask StarPU to allocate room for a piece of data on the specified memory node.

void starpu_data_query_status ( starpu_data_handle_t  handle,
int  memory_node,
int *  is_allocated,
int *  is_valid,
int *  is_requested 
)

Query the status of handle on the specified memory_node.

void starpu_data_advise_as_important ( starpu_data_handle_t  handle,
unsigned  is_important 
)

This function allows to specify that a piece of data can be discarded without impacting the application.

void starpu_data_set_reduction_methods ( starpu_data_handle_t  handle,
struct starpu_codelet *  redux_cl,
struct starpu_codelet *  init_cl 
)

This sets the codelets to be used for handle when it is accessed in the mode STARPU_REDUX. Per-worker buffers will be initialized with the codelet init_cl, and reduction between per-worker buffers will be done with the codelet redux_cl.

int starpu_data_acquire ( starpu_data_handle_t  handle,
enum starpu_data_access_mode  mode 
)

The application must call this function prior to accessing registered data from main memory outside tasks. StarPU ensures that the application will get an up-to-date copy of the data in main memory located where the data was originally registered, and that all concurrent accesses (e.g. from tasks) will be consistent with the access mode specified in the mode argument. starpu_data_release() must be called once the application does not need to access the piece of data anymore. Note that implicit data dependencies are also enforced by starpu_data_acquire(), i.e. starpu_data_acquire() will wait for all tasks scheduled to work on the data, unless they have been disabled explictly by calling starpu_data_set_default_sequential_consistency_flag() or starpu_data_set_sequential_consistency_flag(). starpu_data_acquire() is a blocking call, so that it cannot be called from tasks or from their callbacks (in that case, starpu_data_acquire() returns -EDEADLK). Upon successful completion, this function returns 0.

int starpu_data_acquire_cb ( starpu_data_handle_t  handle,
enum starpu_data_access_mode  mode,
void(*)(void *)  callback,
void *  arg 
)

Asynchronous equivalent of starpu_data_acquire(). When the data specified in handle is available in the appropriate access mode, the callback function is executed. The application may access the requested data during the execution of this callback. The callback function must call starpu_data_release() once the application does not need to access the piece of data anymore. Note that implicit data dependencies are also enforced by starpu_data_acquire_cb() in case they are not disabled. Contrary to starpu_data_acquire(), this function is non-blocking and may be called from task callbacks. Upon successful completion, this function returns 0.

void starpu_data_release ( starpu_data_handle_t  handle)

This function releases the piece of data acquired by the application either by starpu_data_acquire() or by starpu_data_acquire_cb().

Building and Installing StarPU

Installing a Binary Package

One of the StarPU developers being a Debian Developer, the packages are well integrated and very uptodate. To see which packages are available, simply type:

$ apt-cache search starpu

To install what you need, type:

$ sudo apt-get install libstarpu-1.1 libstarpu-dev

Installing from Source

StarPU can be built and installed by the standard means of the GNU autotools. The following chapter is intended to briefly remind how these tools can be used to install StarPU.

Optional Dependencies

The hwloc topology discovery library is not mandatory to use StarPU but strongly recommended. It allows for topology aware scheduling, which improves performance. hwloc is available in major free operating system distributions, and for most operating systems.

If hwloc is not available on your system, the option --without-hwloc should be explicitely given when calling the configure script. If hwloc is installed with a pkg-config file, no option is required, it will be detected automatically, otherwise --with-hwloc should be used to specify the location of hwloc.

Getting Sources

StarPU's sources can be obtained from the download page of the StarPU website.

All releases and the development tree of StarPU are freely available on INRIA's gforge under the LGPL license. Some releases are available under the BSD license.

The latest release can be downloaded from the INRIA's gforge or directly from the StarPU download page.

The latest nightly snapshot can be downloaded from the StarPU gforge website.

$ wget http://starpu.gforge.inria.fr/testing/starpu-nightly-latest.tar.gz

And finally, current development version is also accessible via svn. It should be used only if you need the very latest changes (i.e. less than a day!). Note that the client side of the software Subversion can be obtained from http://subversion.tigris.org. If you are running on Windows, you will probably prefer to use TortoiseSVN.

$ svn checkout svn://scm.gforge.inria.fr/svn/starpu/trunk StarPU

Configuring StarPU

Running autogen.sh is not necessary when using the tarball releases of StarPU. If you are using the source code from the svn repository, you first need to generate the configure scripts and the Makefiles. This requires the availability of autoconf, automake >= 2.60.

$ ./autogen.sh

You then need to configure StarPU. Details about options that are useful to give to ./configure are given in Compilation Configuration.

$ ./configure

If configure does not detect some software or produces errors, please make sure to post the content of config.log when reporting the issue.

By default, the files produced during the compilation are placed in the source directory. As the compilation generates a lot of files, it is advised to to put them all in a separate directory. It is then easier to cleanup, and this allows to compile several configurations out of the same source tree. For that, simply enter the directory where you want the compilation to produce its files, and invoke the configure script located in the StarPU source directory.

$ mkdir build
$ cd build
$ ../configure

By default, StarPU will be installed in /usr/local/bin, /usr/local/lib, etc. You can specify an installation prefix other than /usr/local using the option –prefix, for instance:

$ ../configure --prefix=$HOME/starpu

Building StarPU

$ make

Once everything is built, you may want to test the result. An extensive set of regression tests is provided with StarPU. Running the tests is done by calling make check. These tests are run every night and the result from the main profile is publicly available.

$ make check

Installing StarPU

In order to install StarPU at the location that was specified during configuration:

$ make install

Libtool interface versioning information are included in libraries names (libstarpu-1.1.so, libstarpumpi-1.1.so and libstarpufft-1.1.so).

Setting up Your Own Code

Setting Flags for Compiling, Linking and Running Applications

StarPU provides a pkg-config executable to obtain relevant compiler and linker flags. Compiling and linking an application against StarPU may require to use specific flags or libraries (for instance CUDA or libspe2). To this end, it is possible to use the tool pkg-config.

If StarPU was not installed at some standard location, the path of StarPU's library must be specified in the environment variable PKG_CONFIG_PATH so that pkg-config can find it. For example if StarPU was installed in $prefix_dir:

$ PKG_CONFIG_PATH=$PKG_CONFIG_PATH:$prefix_dir/lib/pkgconfig

The flags required to compile or link against StarPU are then accessible with the following commands:

$ pkg-config --cflags starpu-1.1  # options for the compiler
$ pkg-config --libs starpu-1.1    # options for the linker

Note that it is still possible to use the API provided in the version 0.9 of StarPU by calling pkg-config with the libstarpu package. Similar packages are provided for libstarpumpi and libstarpufft.

Make sure that pkg-config –libs starpu-1.1 actually produces some output before going further: PKG_CONFIG_PATH has to point to the place where starpu-1.1.pc was installed during make install.

Also pass the option –static if the application is to be linked statically.

It is also necessary to set the environment variable LD_LIBRARY_PATH to locate dynamic libraries at runtime.

$ LD_LIBRARY_PATH=$prefix_dir/lib:$LD_LIBRARY_PATH

When using a Makefile, the following lines can be added to set the options for the compiler and the linker:

CFLAGS          +=      $$(pkg-config --cflags starpu-1.1)
LDFLAGS         +=      $$(pkg-config --libs starpu-1.1)

Running a Basic StarPU Application

Basic examples using StarPU are built in the directory examples/basic_examples/ (and installed in $prefix_dir/lib/starpu/examples/). You can for example run the example vector_scal.

$ ./examples/basic_examples/vector_scal
BEFORE: First element was 1.000000
AFTER: First element is 3.140000

When StarPU is used for the first time, the directory $STARPU_HOME/.starpu/ is created, performance models will be stored in that directory (STARPU_HOME).

Please note that buses are benchmarked when StarPU is launched for the first time. This may take a few minutes, or less if hwloc is installed. This step is done only once per user and per machine.

Kernel Threads Started by StarPU

StarPU automatically binds one thread per CPU core. It does not use SMT/hyperthreading because kernels are usually already optimized for using a full core, and using hyperthreading would make kernel calibration rather random.

Since driving GPUs is a CPU-consuming task, StarPU dedicates one core per GPU.

While StarPU tasks are executing, the application is not supposed to do computations in the threads it starts itself, tasks should be used instead.

TODO: add a StarPU function to bind an application thread (e.g. the main thread) to a dedicated core (and thus disable the corresponding StarPU CPU worker).

Enabling OpenCL

When both CUDA and OpenCL drivers are enabled, StarPU will launch an OpenCL worker for NVIDIA GPUs only if CUDA is not already running on them. This design choice was necessary as OpenCL and CUDA can not run at the same time on the same NVIDIA GPU, as there is currently no interoperability between them.

To enable OpenCL, you need either to disable CUDA when configuring StarPU:

$ ./configure --disable-cuda

or when running applications:

$ STARPU_NCUDA=0 ./application

OpenCL will automatically be started on any device not yet used by CUDA. So on a machine running 4 GPUS, it is therefore possible to enable CUDA on 2 devices, and OpenCL on the 2 other devices by doing so:

$ STARPU_NCUDA=2 ./application

Benchmarking StarPU

Some interesting benchmarks are installed among examples in $prefix_dir/lib/starpu/examples/. Make sure to try various schedulers, for instance STARPU_SCHED=dmda.

Task Size Overhead

This benchmark gives a glimpse into how long a task should be (in µs) for StarPU overhead to be low enough to keep efficiency. Run tasks_size_overhead.sh, it will generate a plot of the speedup of tasks of various sizes, depending on the number of CPUs being used.

tasks_size_overhead.png

Data Transfer Latency

local_pingpong performs a ping-pong between the first two CUDA nodes, and prints the measured latency.

Matrix-Matrix Multiplication

sgemm and dgemm perform a blocked matrix-matrix multiplication using BLAS and cuBLAS. They output the obtained GFlops.

Cholesky Factorization

cholesky_* perform a Cholesky factorization (single precision). They use different dependency primitives.

LU Factorization

lu_* perform an LU factorization. They use different dependency primitives.

Simulated benchmarks

It can also be convenient to try simulated benchmarks, if you want to give a try at CPU-GPU scheduling without actually having a GPU at hand. This can be done by using the simgrid version of StarPU: first install the simgrid simulator from http://simgrid.gforge.inria.fr/ , then configure StarPU with --enable-simgrid and rebuild and install it, and then you can simulate the performance for a couple of virtualized system shipped along StarPU: attila and mirage.

For instance:

$ export STARPU_PERF_MODEL_DIR=$STARPU_PATH/share/starpu/perfmodels/sampling
$ export STARPU_HOSTNAME=attila
$ $STARPU_PATH/lib/starpu/examples/cholesky_implicit

Will show the performance of the cholesky factorization with the attila system. It will be interesting to try with different matrix sizes and schedulers.

Performance models are available for cholesky_*, lu_*, *gemm, with block sizes 320, 640, or 960, and for stencil with block size 128x128x128, 192x192x192, and 256x256x256.

Detailed Description

Compute theoretical upper computation efficiency bound corresponding to some actual execution.

Function Documentation

void starpu_bound_start ( int  deps,
int  prio 
)

Start recording tasks (resets stats). deps tells whether dependencies should be recorded too (this is quite expensive)

void starpu_bound_stop ( void  )

Stop recording tasks

void starpu_bound_print_dot ( FILE *  output)

Print the DAG that was recorded

void starpu_bound_compute ( double *  res,
double *  integer_res,
int  integer 
)

Get theoretical upper bound (in ms) (needs glpk support detected by configure script). It returns 0 if some performance models are not calibrated.

void starpu_bound_print_lp ( FILE *  output)

Emit the Linear Programming system on output for the recorded tasks, in the lp format

void starpu_bound_print_mps ( FILE *  output)

Emit the Linear Programming system on output for the recorded tasks, in the mps format

void starpu_bound_print ( FILE *  output,
int  integer 
)

Emit statistics of actual execution vs theoretical upper bound. integer permits to choose between integer solving (which takes a long time but is correct), and relaxed solving (which provides an approximate solution).

Compilation Configuration

The behavior of the StarPU library and tools may be tuned thanks to the following configure options.

Common Configuration

–enable-debug

Enable debugging messages.

–enable-spinlock-check

Enable checking that spinlocks are taken and released properly.

–enable-fast

Disable assertion checks, which saves computation time.

–enable-verbose

Increase the verbosity of the debugging messages. This can be disabled at runtime by setting the environment variable STARPU_SILENT to any value.

$ STARPU_SILENT=1 ./vector_scal

–enable-coverage

Enable flags for the coverage tool gcov.

–enable-quick-check

Specify tests and examples should be run on a smaller data set, i.e allowing a faster execution time

–enable-long-check

Enable some exhaustive checks which take a really long time.

–with-hwloc

Specify hwloc should be used by StarPU. hwloc should be found by the means of the tool pkg-config.

–with-hwloc=prefix

Specify hwloc should be used by StarPU. hwloc should be found in the directory specified by prefix

–without-hwloc

Specify hwloc should not be used by StarPU.

–disable-build-doc
Disable the creation of the documentation. This should be done on a machine which does not have the tools doxygen and latex (plus the packages latex-xcolor and texlive-latex-extra).

Additionally, the script configure recognize many variables, which can be listed by typing ./configure –help. For example, ./configure NVCCFLAGS="-arch sm_13" adds a flag for the compilation of CUDA kernels.

Configuring Workers

–enable-maxcpus=count

Use at most count CPU cores. This information is then available as the macro ::STARPU_MAXCPUS.

–disable-cpu

Disable the use of CPUs of the machine. Only GPUs etc. will be used.

–enable-maxcudadev=count

Use at most count CUDA devices. This information is then available as the macro STARPU_MAXCUDADEVS.

–disable-cuda

Disable the use of CUDA, even if a valid CUDA installation was detected.

–with-cuda-dir=prefix

Search for CUDA under prefix, which should notably contain the file include/cuda.h.

–with-cuda-include-dir=dir

Search for CUDA headers under dir, which should notably contain the file cuda.h. This defaults to /include appended to the value given to --with-cuda-dir.

–with-cuda-lib-dir=dir

Search for CUDA libraries under dir, which should notably contain the CUDA shared libraries—e.g., libcuda.so. This defaults to /lib appended to the value given to --with-cuda-dir.

–disable-cuda-memcpy-peer

Explicitly disable peer transfers when using CUDA 4.0.

–enable-maxopencldev=count

Use at most count OpenCL devices. This information is then available as the macro STARPU_MAXOPENCLDEVS.

–disable-opencl

Disable the use of OpenCL, even if the SDK is detected.

–with-opencl-dir=prefix

Search for an OpenCL implementation under prefix, which should notably contain include/CL/cl.h (or include/OpenCL/cl.h on Mac OS).

–with-opencl-include-dir=dir

Search for OpenCL headers under dir, which should notably contain CL/cl.h (or OpenCL/cl.h on Mac OS). This defaults to /include appended to the value given to --with-opencl-dir.

–with-opencl-lib-dir=dir

Search for an OpenCL library under dir, which should notably contain the OpenCL shared libraries—e.g. libOpenCL.so. This defaults to /lib appended to the value given to --with-opencl-dir.

–enable-opencl-simulator

Enable considering the provided OpenCL implementation as a simulator, i.e. use the kernel duration returned by OpenCL profiling information as wallclock time instead of the actual measured real time. This requires simgrid support.

–enable-maximplementations=count

Allow for at most count codelet implementations for the same target device. This information is then available as the macro ::STARPU_MAXIMPLEMENTATIONS macro.

–enable-max-sched-ctxs=count

Allow for at most count scheduling contexts This information is then available as the macro ::STARPU_NMAX_SCHED_CTXS.

–disable-asynchronous-copy

Disable asynchronous copies between CPU and GPU devices. The AMD implementation of OpenCL is known to fail when copying data asynchronously. When using this implementation, it is therefore necessary to disable asynchronous data transfers.

–disable-asynchronous-cuda-copy

Disable asynchronous copies between CPU and CUDA devices.

–disable-asynchronous-opencl-copy

Disable asynchronous copies between CPU and OpenCL devices. The AMD implementation of OpenCL is known to fail when copying data asynchronously. When using this implementation, it is therefore necessary to disable asynchronous data transfers.

–enable-maxnodes=count

Use at most count memory nodes. This information is then available as the macro ::STARPU_MAXNODES. Reducing it allows to considerably reduce memory used by StarPU data structures.

Extension Configuration

–disable-socl

Disable the SOCL extension (SOCL OpenCL Extensions). By default, it is enabled when an OpenCL implementation is found.

–disable-starpu-top

Disable the StarPU-Top interface (StarPU-Top Interface). By default, it is enabled when the required dependencies are found.

Main Application

/*
* This example demonstrates how to use StarPU to scale an array by a factor.
* It shows how to manipulate data with StarPU's data management library.
* 1- how to declare a piece of data to StarPU (starpu_vector_data_register)
* 2- how to describe which data are accessed by a task (task->handles[0])
* 3- how a kernel can manipulate the data (buffers[0].vector.ptr)

#define STARPU_MALLOC_PINNED

Value passed to the function starpu_malloc_flags() to indicate the memory allocation should be pinned.

#define STARPU_MALLOC_COUNT

Value passed to the function starpu_malloc_flags() to indicate the memory allocation should be in the limit defined by the environment variables STARPU_LIMIT_CUDA_devid_MEM, STARPU_LIMIT_CUDA_MEM, STARPU_LIMIT_OPENCL_devid_MEM, STARPU_LIMIT_OPENCL_MEM and STARPU_LIMIT_CPU_MEM (see Section How to limit memory per node). If no memory is available, it tries to reclaim memory from StarPU. Memory allocated this way needs to be freed by calling the function starpu_free_flags() with the same flag.

Function Documentation

int starpu_malloc_flags ( void **  A,
size_t  dim,
int  flags 
)

Performs a memory allocation based on the constraints defined by the given flag.

void starpu_malloc_set_align ( size_t  align)

This function sets an alignment constraints for starpu_malloc() allocations. align must be a power of two. This is for instance called automatically by the OpenCL driver to specify its own alignment constraints.

int starpu_malloc ( void **  A,
size_t  dim 
)

This function allocates data of the given size in main memory. It will also try to pin it in CUDA or OpenCL, so that data transfers from this buffer can be asynchronous, and thus permit data transfer and computation overlapping. The allocated buffer must be freed thanks to the starpu_free() function.

int starpu_free ( void *  A)

This function frees memory which has previously been allocated with starpu_malloc().

int starpu_free_flags ( void *  A,
size_t  dim,
int  flags 
)

This function frees memory by specifying its size. The given flags should be consistent with the ones given to starpu_malloc_flags() when allocating the memory.

int starpu_memory_pin ( void *  addr,
size_t  size 
)

This function pins the given memory area, so that CPU-GPU transfers can be done asynchronously with DMAs. The memory must be unpinned with starpu_memory_unpin() before being freed. Returns 0 on success, -1 on error.

int starpu_memory_unpin ( void *  addr,
size_t  size 
)

This function unpins the given memory area previously pinned with starpu_memory_pin(). Returns 0 on success, -1 on error.

starpu_ssize_t starpu_memory_get_total ( unsigned  node)

If a memory limit is defined on the given node (see Section How to limit memory per node), return the amount of total memory on the node. Otherwise return -1.

starpu_ssize_t starpu_memory_get_available ( unsigned  node)

If a memory limit is defined on the given node (see Section How to limit memory per node), return the amount of available memory on the node. Otherwise return -1.

void starpu_memory_wait_available ( unsigned  node,
size_t  size 
)

node (see Section How to limit memory per node), this will wait for size bytes to become available on node. Of course, since another thread may be allocating memory concurrently, this does not necessarily mean that this amount will be actually available, just that it was reached.

Registering Data

There are several ways to register a memory region so that it can be managed by StarPU. The functions below allow the registration of vectors, 2D matrices, 3D matrices as well as BCSR and CSR sparse matrices.

void starpu_void_data_register (starpu_data_handle_t *handle)
void starpu_variable_data_register (starpu_data_handle_t *handle, unsigned home_node, uintptr_t ptr, size_t size)

Function Documentation

void starpu_void_data_register ( starpu_data_handle_t *  handle)

Register a void interface. There is no data really associated to that interface, but it may be used as a synchronization mechanism. It also permits to express an abstract piece of data that is managed by the application internally: this makes it possible to forbid the concurrent execution of different tasks accessing the same void data in read-write concurrently.

void starpu_variable_data_register ( starpu_data_handle_t *  handle,
unsigned  home_node,
uintptr_t  ptr,
size_t  size 
)

Register the size byte element pointed to by ptr, which is typically a scalar, and initialize handle to represent this data item.

Here an example of how to use the function.

float var;
starpu_data_handle_t var_handle;
starpu_variable_data_register(&var_handle, 0, (uintptr_t)&var, sizeof(var));
void starpu_vector_data_register ( starpu_data_handle_t *  handle,
unsigned  home_node,
uintptr_t  ptr,
uint32_t  nx,
size_t  elemsize 
)

Register the nx elemsize-byte elements pointed to by ptr and initialize handle to represent it.

Here an example of how to use the function.

float vector[NX];
starpu_data_handle_t vector_handle;
starpu_vector_data_register(&vector_handle, 0, (uintptr_t)vector, NX, sizeof(vector[0]));
void starpu_vector_ptr_register ( starpu_data_handle_t  handle,
unsigned  node,
uintptr_t  ptr,
uintptr_t  dev_handle,
size_t  offset 
)

Register into the handle that to store data on node node it should use the buffer located at ptr, or device handle dev_handle and offset offset (for OpenCL, notably)

void starpu_matrix_data_register ( starpu_data_handle_t *  handle,
unsigned  home_node,
uintptr_t  ptr,
uint32_t  ld,
uint32_t  nx,
uint32_t  ny,
size_t  elemsize 
)

Register the nx x ny 2D matrix of elemsize-byte elements pointed by ptr and initialize handle to represent it. ld specifies the number of elements between rows. a value greater than nx adds padding, which can be useful for alignment purposes.

Here an example of how to use the function.

float *matrix;
starpu_data_handle_t matrix_handle;
matrix = (float*)malloc(width * height * sizeof(float));
starpu_matrix_data_register(&matrix_handle, 0, (uintptr_t)matrix, width, width, height, sizeof(float));
void starpu_matrix_ptr_register ( starpu_data_handle_t  handle,
unsigned  node,
uintptr_t  ptr,
uintptr_t  dev_handle,
size_t  offset,
uint32_t  ld 
)

Register into the handle that to store data on node node it should use the buffer located at ptr, or device handle dev_handle and offset offset (for OpenCL, notably), with ld elements between rows.

void starpu_block_data_register ( starpu_data_handle_t *  handle,
unsigned  home_node,
uintptr_t  ptr,
uint32_t  ldy,
uint32_t  ldz,
uint32_t  nx,
uint32_t  ny,
uint32_t  nz,
size_t  elemsize 
)

Register the nx x ny x nz 3D matrix of elemsize byte elements pointed by ptr and initialize handle to represent it. Again, ldy and ldz specify the number of elements between rows and between z planes.

Here an example of how to use the function.

float *block;
starpu_data_handle_t block_handle;
block = (float*)malloc(nx*ny*nz*sizeof(float));
starpu_block_data_register(&block_handle, 0, (uintptr_t)block, nx, nx*ny, nx, ny, nz, sizeof(float));
void starpu_block_ptr_register ( starpu_data_handle_t  handle,
unsigned  node,
uintptr_t  ptr,
uintptr_t  dev_handle,
size_t  offset,
uint32_t  ldy,
uint32_t  ldz 
)

Register into the handle that to store data on node node it should use the buffer located at ptr, or device handle dev_handle and offset offset (for OpenCL, notably), with ldy elements between rows and elements between z planes.

void starpu_bcsr_data_register ( starpu_data_handle_t *  handle,
unsigned  home_node,
uint32_t  nnz,
uint32_t  nrow,
uintptr_t  nzval,
uint32_t *  colind,
uint32_t *  rowptr,
uint32_t  firstentry,
uint32_t  r,
uint32_t  c,
size_t  elemsize 
)

This variant of starpu_data_register() uses the BCSR (Blocked Compressed Sparse Row Representation) sparse matrix interface. Register the sparse matrix made of nnz non-zero blocks of elements of size elemsize stored in nzval and initializes handle to represent it. Blocks have size r * c. nrow is the number of rows (in terms of blocks), colind[i] is the block-column index for block i in nzval, rowptr[i] is the block-index (in nzval) of the first block of row i. firstentry is the index of the first entry of the given arrays (usually 0 or 1).

void starpu_csr_data_register ( starpu_data_handle_t *  handle,
unsigned  home_node,
uint32_t  nnz,
uint32_t  nrow,
uintptr_t  nzval,
uint32_t *  colind,
uint32_t *  rowptr,
uint32_t  firstentry,
size_t  elemsize 
)

This variant of starpu_data_register() uses the CSR (Compressed Sparse Row Representation) sparse matrix interface. TODO

Detailed Description

Function Documentation

void * starpufft_malloc ( size_t  n)

Allocates memory for n bytes. This is preferred over malloc(), since it allocates pinned memory, which allows overlapped transfers.

void * starpufft_free ( void *  p)

Release memory previously allocated.

struct starpufft_plan * starpufft_plan_dft_1d ( int  n,
int  sign,
unsigned  flags 
)

Initializes a plan for 1D FFT of size n. sign can be STARPUFFT_FORWARD or STARPUFFT_INVERSE. flags must be 0.

struct starpufft_plan * starpufft_plan_dft_2d ( int  n,
int  m,
int  sign,
unsigned  flags 
)

Initializes a plan for 2D FFT of size (n, m). sign can be STARPUFFT_FORWARD or STARPUFFT_INVERSE. flags must be 0.

struct starpu_task * starpufft_start ( starpufft_plan  p,
void *  in,
void *  out 
)
read

Start an FFT previously planned as p, using in and out as input and output. This only submits the task and does not wait for it. The application should call starpufft_cleanup() to unregister the

struct starpu_task * starpufft_start_handle ( starpufft_plan  p,
starpu_data_handle_t  in,
starpu_data_handle_t  out 
)
read

Start an FFT previously planned as p, using data handles in and out as input and output (assumed to be vectors of elements of the expected types). This only submits the task and does not wait for it.

void starpufft_execute ( starpufft_plan  p,
void *  in,
void *  out 
)

Execute an FFT previously planned as p, using in and out as input and output. This submits and waits for the task.

void starpufft_execute_handle ( starpufft_plan  p,
starpu_data_handle_t  in,
starpu_data_handle_t  out 
)

Execute an FFT previously planned as p, using data handles in and out as input and output (assumed to be vectors of elements of the expected types). This submits and waits for the task.

void starpufft_cleanup ( starpufft_plan  p)

Releases data for plan p, in the starpufft_start() case.

void starpufft_destroy_plan ( starpufft_plan  p)

Destroys plan p, i.e. release all CPU (fftw) and GPU (cufft) resources.

Calls starpu_cublas_report_error(), passing the current function, file and line position.

Function Documentation

cudaStream_t starpu_cuda_get_local_stream ( void  )

This function gets the current worker’s CUDA stream. StarPU provides a stream for every CUDA device controlled by StarPU. This function is only provided for convenience so that programmers can easily use asynchronous operations within codelets without having to create a stream by hand. Note that the application is not forced to use the stream provided by starpu_cuda_get_local_stream() and may also create its own streams. Synchronizing with cudaThreadSynchronize() is allowed, but will reduce the likelihood of having all transfers overlapped.

const struct cudaDeviceProp * starpu_cuda_get_device_properties ( unsigned  workerid)
read

This function returns a pointer to device properties for worker workerid (assumed to be a CUDA worker).

void starpu_cuda_report_error ( const char *  func,
const char *  file,
int  line,
cudaError_t  status 
)

Report a CUDA error.

int starpu_cuda_copy_async_sync ( void *  src_ptr,
unsigned  src_node,
void *  dst_ptr,
unsigned  dst_node,
size_t  ssize,
cudaStream_t  stream,
enum cudaMemcpyKind  kind 
)

Copy ssize bytes from the pointer src_ptr on src_node to the pointer dst_ptr on dst_node. The function first tries to copy the data asynchronous (unless stream is NULL). If the asynchronous copy fails or if stream is NULL, it copies the data synchronously. The function returns -EAGAIN if the asynchronous launch was successfull. It returns 0 if the synchronous copy was successful, or fails otherwise.

void starpu_cuda_set_device ( unsigned  devid)

Calls cudaSetDevice(devid) or cudaGLSetGLDevice(devid), according to whether devid is among the field starpu_conf::cuda_opengl_interoperability.

void starpu_cublas_init ( void  )

This function initializes CUBLAS on every CUDA device. The CUBLAS library must be initialized prior to any CUBLAS call. Calling starpu_cublas_init() will initialize CUBLAS on every CUDA device controlled by StarPU. This call blocks until CUBLAS has been properly initialized on every device.

void starpu_cublas_shutdown ( void  )

This function synchronously deinitializes the CUBLAS library on every CUDA device.

int starpu_data_cpy ( starpu_data_handle_t  dst_handle,
starpu_data_handle_t  src_handle,
int  asynchronous,
void(*)(void *)  callback_func,
void *  callback_arg 
)

Copy the content of src_handle into dst_handle. The parameter asynchronous indicates whether the function should block or not. In the case of an asynchronous call, it is possible to synchronize with the termination of this operation either by the means of implicit dependencies (if enabled) or by calling starpu_task_wait_for_all(). If callback_func is not NULL, this callback function is executed after the handle has been copied, and it is given the pointer callback_arg as argument.

void starpu_execute_on_each_worker ( void(*)(void *)  func,
void *  arg,
uint32_t  where 
)

This function executes the given function on a subset of workers. When calling this method, the offloaded function func is executed by every StarPU worker that may execute the function. The argument arg is passed to the offloaded function. The argument where specifies on which types of processing units the function should be executed. Similarly to the field starpu_codelet::where, it is possible to specify that the function should be executed on every CUDA device and every CPU by passing STARPU_CPU|STARPU_CUDA. This function blocks until the function has been executed on every appropriate processing units, so that it may not be called from a callback function for instance.

Using Multiple Implementations Of A Codelet

One may want to write multiple implementations of a codelet for a single type of device and let StarPU choose which one to run. As an example, we will show how to use SSE to scale a vector. The codelet can be written as follows:

#include <xmmintrin.h>
void scal_sse_func(void *buffers[], void *cl_arg)
{
float *vector = (float *) STARPU_VECTOR_GET_PTR(buffers[0]);
unsigned int n = STARPU_VECTOR_GET_NX(buffers[0]);
unsigned int n_iterations = n/4;
if (n % 4 != 0)
n_iterations++;
__m128 *VECTOR = (__m128*) vector;
__m128 factor __attribute__((aligned(16)));
factor = _mm_set1_ps(*(float *) cl_arg);
unsigned int i;
for (i = 0; i < n_iterations; i++)
VECTOR[i] = _mm_mul_ps(factor, VECTOR[i]);
}
struct starpu_codelet cl = {
.where = STARPU_CPU,
.cpu_funcs = { scal_cpu_func, scal_sse_func},
.nbuffers = 1,
.modes = { STARPU_RW }
};

Schedulers which are multi-implementation aware (only dmda and pheft for now) will use the performance models of all the implementations it was given, and pick the one that seems to be the fastest.

Enabling Implementation According To Capabilities

Some implementations may not run on some devices. For instance, some CUDA devices do not support double floating point precision, and thus the kernel execution would just fail; or the device may not have enough shared memory for the implementation being used. The field starpu_codelet::can_execute permits to express this. For instance:

static int can_execute(unsigned workerid, struct starpu_task *task, unsigned nimpl)
{
const struct cudaDeviceProp *props;
if (starpu_worker_get_type(workerid) == STARPU_CPU_WORKER)
return 1;
/* Cuda device */
props = starpu_cuda_get_device_properties(workerid);
if (props->major >= 2 || props->minor >= 3)
/* At least compute capability 1.3, supports doubles */
return 1;
/* Old card, does not support doubles */
return 0;
}
struct starpu_codelet cl = {
.where = STARPU_CPU|STARPU_CUDA,
.can_execute = can_execute,
.cpu_funcs = { cpu_func},
.cuda_funcs = { gpu_func}
.nbuffers = 1,
.modes = { STARPU_RW }
};

This can be essential e.g. when running on a machine which mixes various models of CUDA devices, to take benefit from the new models without crashing on old models.

Note: the function starpu_codelet::can_execute is called by the scheduler each time it tries to match a task with a worker, and should thus be very fast. The function starpu_cuda_get_device_properties() provides a quick access to CUDA properties of CUDA devices to achieve such efficiency.

Another example is to compile CUDA code for various compute capabilities, resulting with two CUDA functions, e.g. scal_gpu_13 for compute capability 1.3, and scal_gpu_20 for compute capability 2.0. Both functions can be provided to StarPU by using starpu_codelet::cuda_funcs, and starpu_codelet::can_execute can then be used to rule out the scal_gpu_20 variant on a CUDA device which will not be able to execute it:

static int can_execute(unsigned workerid, struct starpu_task *task, unsigned nimpl)
{
const struct cudaDeviceProp *props;
if (starpu_worker_get_type(workerid) == STARPU_CPU_WORKER)
return 1;
/* Cuda device */
if (nimpl == 0)
/* Trying to execute the 1.3 capability variant, we assume it is ok in all cases. */
return 1;
/* Trying to execute the 2.0 capability variant, check that the card can do it. */
props = starpu_cuda_get_device_properties(workerid);
if (props->major >= 2 || props->minor >= 0)
/* At least compute capability 2.0, can run it */
return 1;
/* Old card, does not support 2.0, will not be able to execute the 2.0 variant. */
return 0;
}
struct starpu_codelet cl = {
.where = STARPU_CPU|STARPU_CUDA,
.can_execute = can_execute,
.cpu_funcs = { cpu_func},
.cuda_funcs = { scal_gpu_13, scal_gpu_20},
.nbuffers = 1,
.modes = { STARPU_RW }
};

Another example is having specialized implementations for some given common sizes, for instance here we have a specialized implementation for 1024x1024 matrices:

static int can_execute(unsigned workerid, struct starpu_task *task, unsigned nimpl)
{
const struct cudaDeviceProp *props;
if (starpu_worker_get_type(workerid) == STARPU_CPU_WORKER)
return 1;
/* Cuda device */
switch (nimpl)
{
case 0:
/* Trying to execute the generic capability variant. */
return 1;
case 1:
{
/* Trying to execute the size == 1024 specific variant. */
struct starpu_matrix_interface *interface = starpu_data_get_interface_on_node(task->handles[0]);
return STARPU_MATRIX_GET_NX(interface) == 1024 && STARPU_MATRIX_GET_NY(interface == 1024);
}
}
}
struct starpu_codelet cl = {
.can_execute = can_execute,
.cpu_funcs = { cpu_func},
.cpu_funcs_name = { "cpu_func"},
.cuda_funcs = { potrf_gpu_generic, potrf_gpu_1024},
.nbuffers = 1,
.modes = { STARPU_RW }
};

Note: the most generic variant should be provided first, as some schedulers are not able to try the different variants.

Task And Worker Profiling

A full example showing how to use the profiling API is available in the StarPU sources in the directory examples/profiling/.

struct starpu_task *task = starpu_task_create();
task->cl = &cl;
task->synchronous = 1;
/* We will destroy the task structure by hand so that we can
query the profiling info before the task is destroyed. */
task->destroy = 0;
/* Submit and wait for completion (since synchronous was set to 1) */
starpu_task_submit(task);
/* The task is finished, get profiling information */
struct starpu_profiling_task_info *info = task->profiling_info;
/* How much time did it take before the task started ? */
double delay += starpu_timing_timespec_delay_us(&info->submit_time, &info->start_time);
/* How long was the task execution ? */
double length += starpu_timing_timespec_delay_us(&info->start_time, &info->end_time);
/* We don't need the task structure anymore */
starpu_task_destroy(task);
/* Display the occupancy of all workers during the test */
int worker;
for (worker = 0; worker < starpu_worker_get_count(); worker++)
{
struct starpu_profiling_worker_info worker_info;
int ret = starpu_profiling_worker_get_info(worker, &worker_info);
STARPU_ASSERT(!ret);
double total_time = starpu_timing_timespec_to_us(&worker_info.total_time);
double executing_time = starpu_timing_timespec_to_us(&worker_info.executing_time);
double sleeping_time = starpu_timing_timespec_to_us(&worker_info.sleeping_time);
double overhead_time = total_time - executing_time - sleeping_time;
float executing_ratio = 100.0*executing_time/total_time;
float sleeping_ratio = 100.0*sleeping_time/total_time;
float overhead_ratio = 100.0 - executing_ratio - sleeping_ratio;
char workername[128];
starpu_worker_get_name(worker, workername, 128);
fprintf(stderr, "Worker %s:\n", workername);
fprintf(stderr, "\ttotal time: %.2lf ms\n", total_time*1e-3);
fprintf(stderr, "\texec time: %.2lf ms (%.2f %%)\n",
executing_time*1e-3, executing_ratio);
fprintf(stderr, "\tblocked time: %.2lf ms (%.2f %%)\n",
sleeping_time*1e-3, sleeping_ratio);
fprintf(stderr, "\toverhead time: %.2lf ms (%.2f %%)\n",
overhead_time*1e-3, overhead_ratio);
}

Partitioning Data

An existing piece of data can be partitioned in sub parts to be used by different tasks, for instance:

int vector[NX];
starpu_data_handle_t handle;
/* Declare data to StarPU */
starpu_vector_data_register(&handle, 0, (uintptr_t)vector,
NX, sizeof(vector[0]));
/* Partition the vector in PARTS sub-vectors */
struct starpu_data_filter f =
{
.filter_func = starpu_vector_filter_block,
.nchildren = PARTS
};
starpu_data_partition(handle, &f);

The task submission then uses the function starpu_data_get_sub_data() to retrieve the sub-handles to be passed as tasks parameters.

/* Submit a task on each sub-vector */
for (i=0; i<starpu_data_get_nb_children(handle); i++) {
/* Get subdata number i (there is only 1 dimension) */
starpu_data_handle_t sub_handle = starpu_data_get_sub_data(handle, 1, i);
struct starpu_task *task = starpu_task_create();
task->handles[0] = sub_handle;
task->cl = &cl;
task->synchronous = 1;
task->cl_arg = &factor;
task->cl_arg_size = sizeof(factor);
starpu_task_submit(task);
}

Partitioning can be applied several times, see examples/basic_examples/mult.c and examples/filters/.

Wherever the whole piece of data is already available, the partitioning will be done in-place, i.e. without allocating new buffers but just using pointers inside the existing copy. This is particularly important to be aware of when using OpenCL, where the kernel parameters are not pointers, but handles. The kernel thus needs to be also passed the offset within the OpenCL buffer:

void opencl_func(void *buffers[], void *cl_arg)
{
cl_mem vector = (cl_mem) STARPU_VECTOR_GET_DEV_HANDLE(buffers[0]);
unsigned offset = STARPU_BLOCK_GET_OFFSET(buffers[0]);
...
clSetKernelArg(kernel, 0, sizeof(vector), &vector);
clSetKernelArg(kernel, 1, sizeof(offset), &offset);
...
}

And the kernel has to shift from the pointer passed by the OpenCL driver:

__kernel void opencl_kernel(__global int *vector, unsigned offset)
{
block = (__global void *)block + offset;
...
}

StarPU provides various interfaces and filters for matrices, vectors, etc., but applications can also write their own data interfaces and filters, see examples/interface and examples/filters/custom_mf for an example.

Multiple views

Partitioning is synchronous, which can be a problem for dynamic applications. Another way is to register several views on the same piece of data. fmultiple_manual is a complete example using this technique.

In short, we first register the same matrix several times:

starpu_matrix_data_register(&handle, 0, (uintptr_t)matrix, NX, NX, NY, sizeof(matrix[0]));
for (i = 0; i < PARTS; i++)
starpu_matrix_data_register(&vert_handle[i], 0, (uintptr_t)&matrix[0][i*(NX/PARTS)], NX, NX/PARTS, NY, sizeof(matrix[0][0]));

Since StarPU is not aware that the two handles are actually pointing to the same data, we have a danger of inadvertently submitting tasks to both views, which will bring a mess since StarPU will not guarantee any coherency between the two views. To make sure we don't do this, we invalidate the view that we will not use:

for (i = 0; i < PARTS; i++)
starpu_data_invalidate(vert_handle[i]);

Then we can safely work on handle.

When we want to switch to the vertical slice view, all we need to do is bring coherency between them by running an empty task on the home node of the data:

void empty(void *buffers[] STARPU_ATTRIBUTE_UNUSED, void *cl_arg STARPU_ATTRIBUTE_UNUSED)
{ }
struct starpu_codelet cl_switch =
{
.cpu_funcs = {empty},
.nbuffers = 3,
.modes = {STARPU_RW, STARPU_W, STARPU_W},
};
ret = starpu_task_insert(&cl_switch, STARPU_RW, handle,
STARPU_W, vert_handle[0],
STARPU_W, vert_handle[1],
0);

The execution of the switch task will get back the matrix data into the main memory, and thus the vertical slices will get the updated value there.

Again, we prefer to make sure that we don't accidentally access the matrix through the whole-matrix handle:

starpu_data_invalidate_submit(handle);
\end
And now we can start using vertical slices, etc.
\section PerformanceModelExample Performance Model Example
To achieve good scheduling, StarPU scheduling policies need to be able to
estimate in advance the duration of a task. This is done by giving to codelets
a performance model, by defining a structure starpu_perfmodel and
providing its address in the field starpu_codelet::model. The fields
starpu_perfmodel::symbol and starpu_perfmodel::type are mandatory, to
give a name to the model, and the type of the model, since there are
several kinds of performance models. For compatibility, make sure to
initialize the whole structure to zero, either by using explicit
memset(), or by letting the compiler implicitly do it as examplified
below.
<ul>
<li>
Measured at runtime (model type ::STARPU_HISTORY_BASED). This assumes that for a
given set of data input/output sizes, the performance will always be about the
same. This is very true for regular kernels on GPUs for instance (<0.1% error),
and just a bit less true on CPUs (~=1% error). This also assumes that there are
few different sets of data input/output sizes. StarPU will then keep record of
the average time of previous executions on the various processing units, and use
it as an estimation. History is done per task size, by using a hash of the input
and ouput sizes as an index.
It will also save it in <c>$STARPU_HOME/.starpu/sampling/codelets</c>
for further executions, and can be observed by using the tool
<c>starpu_perfmodel_display</c>, or drawn by using
the tool <c>starpu_perfmodel_plot</c> (\ref PerformanceModelCalibration). The
models are indexed by machine name. To
share the models between machines (e.g. for a homogeneous cluster), use
<c>export STARPU_HOSTNAME=some_global_name</c>. Measurements are only done
when using a task scheduler which makes use of it, such as
<c>dmda</c>. Measurements can also be provided explicitly by the application, by
using the function starpu_perfmodel_update_history().
The following is a small code example.
If e.g. the code is recompiled with other compilation options, or several
variants of the code are used, the symbol string should be changed to reflect
that, in order to recalibrate a new model from zero. The symbol string can even
be constructed dynamically at execution time, as long as this is done before
submitting any task using it.
\code{.c}
static struct starpu_perfmodel mult_perf_model = {
.type = STARPU_HISTORY_BASED,
.symbol = "mult_perf_model"
};
struct starpu_codelet cl = {
.where = STARPU_CPU,
.cpu_funcs = { cpu_mult},
.nbuffers = 3,
.modes = { STARPU_R, STARPU_R, STARPU_W },
/* for the scheduling policy to be able to use performance models */
.model = &mult_perf_model
};

Measured at runtime and refined by regression (model types STARPU_REGRESSION_BASED and STARPU_NL_REGRESSION_BASED). This still assumes performance regularity, but works with various data input sizes, by applying regression over observed execution times. STARPU_REGRESSION_BASED uses an a*n^b regression form, STARPU_NL_REGRESSION_BASED uses an a*n^b+c (more precise than STARPU_REGRESSION_BASED, but costs a lot more to compute).

For instance, tests/perfmodels/regression_based.c uses a regression-based performance model for the function memset().

Of course, the application has to issue tasks with varying size so that the regression can be computed. StarPU will not trust the regression unless there is at least 10% difference between the minimum and maximum observed input size. It can be useful to set the environment variable STARPU_CALIBRATE to 1 and run the application on varying input sizes with STARPU_SCHED set to dmda scheduler, so as to feed the performance model for a variety of inputs. The application can also provide the measurements explictly by using the function starpu_perfmodel_update_history(). The tools starpu_perfmodel_display and starpu_perfmodel_plot can be used to observe how much the performance model is calibrated (Performance Model Calibration); when their output look good, STARPU_CALIBRATE can be reset to 0 to let StarPU use the resulting performance model without recording new measures, and STARPU_SCHED can be set to dmda to benefit from the performance models. If the data input sizes vary a lot, it is really important to set STARPU_CALIBRATE to 0, otherwise StarPU will continue adding the measures, and result with a very big performance model, which will take time a lot of time to load and save.

For non-linear regression, since computing it is quite expensive, it is only done at termination of the application. This means that the first execution of the application will use only history-based performance model to perform scheduling, without using regression.

Provided as an estimation from the application itself (model type STARPU_COMMON and field starpu_perfmodel::cost_function), see for instance examples/common/blas_model.h and examples/common/blas_model.c.

Provided explicitly by the application (model type STARPU_PER_ARCH): the fields .per_arch[arch][nimpl].cost_function have to be filled with pointers to functions which return the expected duration of the task in micro-seconds, one per architecture.

For STARPU_HISTORY_BASED, STARPU_REGRESSION_BASED, and STARPU_NL_REGRESSION_BASED, the total size of task data (both input and output) is used as an index by default. The field starpu_perfmodel::size_base however permits the application to override that, when for instance some of the data do not matter for task cost (e.g. mere reference table), or when using sparse structures (in which case it is the number of non-zeros which matter), or when there is some hidden parameter such as the number of iterations, or when the application actually has a very good idea of the complexity of the algorithm, and just not the speed of the processor, etc. The example in the directory examples/pi uses this to include the number of iterations in the base.

StarPU will automatically determine when the performance model is calibrated, or rather, it will assume the performance model is calibrated until the application submits a task for which the performance can not be predicted. For STARPU_HISTORY_BASED, StarPU will require 10 (STARPU_CALIBRATE_MINIMUM) measurements for a given size before estimating that an average can be taken as estimation for further executions with the same size. For STARPU_REGRESSION_BASED and STARPU_NL_REGRESSION_BASED, StarPU will require 10 (STARPU_CALIBRATE_MINIMUM) measurements, and that the minimum measured data size is smaller than 90% of the maximum measured data size (i.e. the measurement interval is large enough for a regression to have a meaning). Calibration can also be forced by setting the STARPU_CALIBRATE environment variable to 1, or even reset by setting it to 2.

How to use schedulers which can benefit from such performance model is explained in Task Scheduling Policy.

The same can be done for task power consumption estimation, by setting the field starpu_codelet::power_model the same way as the field starpu_codelet::model. Note: for now, the application has to give to the power consumption performance model a name which is different from the execution time performance model.

The application can request time estimations from the StarPU performance models by filling a task structure as usual without actually submitting it. The data handles can be created by calling any of the functions starpu_*_data_register with a NULL pointer and -1 node and the desired data sizes, and need to be unregistered as usual. The functions starpu_task_expected_length() and starpu_task_expected_power() can then be called to get an estimation of the task cost on a given arch. starpu_task_footprint() can also be used to get the footprint used for indexing history-based performance models. starpu_task_destroy() needs to be called to destroy the dummy task afterwards. See tests/perfmodels/regression_based.c for an example.

Theoretical Lower Bound On Execution Time Example

For kernels with history-based performance models (and provided that they are completely calibrated), StarPU can very easily provide a theoretical lower bound for the execution time of a whole set of tasks. See for instance examples/lu/lu_example.c: before submitting tasks, call the function starpu_bound_start(), and after complete execution, call starpu_bound_stop(). starpu_bound_print_lp() or starpu_bound_print_mps() can then be used to output a Linear Programming problem corresponding to the schedule of your tasks. Run it through lp_solve or any other linear programming solver, and that will give you a lower bound for the total execution time of your tasks. If StarPU was compiled with the library glpk installed, starpu_bound_compute() can be used to solve it immediately and get the optimized minimum, in ms. Its parameter integer allows to decide whether integer resolution should be computed and returned

The deps parameter tells StarPU whether to take tasks, implicit data, and tag dependencies into account. Tags released in a callback or similar are not taken into account, only tags associated with a task are. It must be understood that the linear programming problem size is quadratic with the number of tasks and thus the time to solve it will be very long, it could be minutes for just a few dozen tasks. You should probably use lp_solve -timeout 1 test.pl -wmps test.mps to convert the problem to MPS format and then use a better solver, glpsol might be better than lp_solve for instance (the –pcost option may be useful), but sometimes doesn't manage to converge. cbc might look slower, but it is parallel. For lp_solve, be sure to try at least all the -B options. For instance, we often just use lp_solve -cc -B1 -Bb -Bg -Bp -Bf -Br -BG -Bd -Bs -BB -Bo -Bc -Bi , and the -gr option can also be quite useful. The resulting schedule can be observed by using the tool starpu_lp2paje, which converts it into the Paje format.

Data transfer time can only be taken into account when deps is set. Only data transfers inferred from implicit data dependencies between tasks are taken into account. Other data transfers are assumed to be completely overlapped.

Setting deps to 0 will only take into account the actual computations on processing units. It however still properly takes into account the varying performances of kernels and processing units, which is quite more accurate than just comparing StarPU performances with the fastest of the kernels being used.

The prio parameter tells StarPU whether to simulate taking into account the priorities as the StarPU scheduler would, i.e. schedule prioritized tasks before less prioritized tasks, to check to which extend this results to a less optimal solution. This increases even more computation time.

Insert Task Utility

StarPU provides the wrapper function starpu_insert_task() to ease the creation and submission of tasks.

Here the implementation of the codelet:

void func_cpu(void *descr[], void *_args)
{
int *x0 = (int *)STARPU_VARIABLE_GET_PTR(descr[0]);
float *x1 = (float *)STARPU_VARIABLE_GET_PTR(descr[1]);
int ifactor;
float ffactor;
starpu_codelet_unpack_args(_args, &ifactor, &ffactor);
*x0 = *x0 * ifactor;
*x1 = *x1 * ffactor;
}
struct starpu_codelet mycodelet = {
.where = STARPU_CPU,
.cpu_funcs = { func_cpu},
.nbuffers = 2,
.modes = { STARPU_RW, STARPU_RW }
};

And the call to the function starpu_insert_task():

starpu_insert_task(&mycodelet,
STARPU_VALUE, &ifactor, sizeof(ifactor),
STARPU_VALUE, &ffactor, sizeof(ffactor),
STARPU_RW, data_handles[0], STARPU_RW, data_handles[1],
0);

The call to starpu_insert_task() is equivalent to the following code:

struct starpu_task *task = starpu_task_create();
task->cl = &mycodelet;
task->handles[0] = data_handles[0];
task->handles[1] = data_handles[1];
char *arg_buffer;
size_t arg_buffer_size;
starpu_codelet_pack_args(&arg_buffer, &arg_buffer_size,
STARPU_VALUE, &ifactor, sizeof(ifactor),
STARPU_VALUE, &ffactor, sizeof(ffactor),
0);
task->cl_arg = arg_buffer;
task->cl_arg_size = arg_buffer_size;
int ret = starpu_task_submit(task);

Here a similar call using STARPU_DATA_ARRAY.

starpu_insert_task(&mycodelet,
STARPU_DATA_ARRAY, data_handles, 2,
STARPU_VALUE, &ifactor, sizeof(ifactor),
STARPU_VALUE, &ffactor, sizeof(ffactor),
0);

If some part of the task insertion depends on the value of some computation, the macro STARPU_DATA_ACQUIRE_CB can be very convenient. For instance, assuming that the index variable i was registered as handle A_handle[i]:

/* Compute which portion we will work on, e.g. pivot */
starpu_insert_task(&which_index, STARPU_W, i_handle, 0);
/* And submit the corresponding task */
STARPU_DATA_ACQUIRE_CB(i_handle, STARPU_R,
starpu_insert_task(&work, STARPU_RW, A_handle[i], 0));

The macro STARPU_DATA_ACQUIRE_CB submits an asynchronous request for acquiring data i for the main application, and will execute the code given as third parameter when it is acquired. In other words, as soon as the value of i computed by the codelet which_index can be read, the portion of code passed as third parameter of STARPU_DATA_ACQUIRE_CB will be executed, and is allowed to read from i to use it e.g. as an index. Note that this macro is only avaible when compiling StarPU with the compiler gcc.

Data Reduction

In various cases, some piece of data is used to accumulate intermediate results. For instances, the dot product of a vector, maximum/minimum finding, the histogram of a photograph, etc. When these results are produced along the whole machine, it would not be efficient to accumulate them in only one place, incurring data transmission each and access concurrency.

StarPU provides a mode STARPU_REDUX, which permits to optimize that case: it will allocate a buffer on each memory node, and accumulate intermediate results there. When the data is eventually accessed in the normal mode STARPU_R, StarPU will collect the intermediate results in just one buffer.

For this to work, the user has to use the function starpu_data_set_reduction_methods() to declare how to initialize these buffers, and how to assemble partial results.

For instance, cg uses that to optimize its dot product: it first defines the codelets for initialization and reduction:

struct starpu_codelet bzero_variable_cl =
{
.cpu_funcs = { bzero_variable_cpu},
.cuda_funcs = { bzero_variable_cuda},
.nbuffers = 1,
}
static void accumulate_variable_cpu(void *descr[], void *cl_arg)
{
double *v_dst = (double *)STARPU_VARIABLE_GET_PTR(descr[0]);
double *v_src = (double *)STARPU_VARIABLE_GET_PTR(descr[1]);
*v_dst = *v_dst + *v_src;
}
static void accumulate_variable_cuda(void *descr[], void *cl_arg)
{
double *v_dst = (double *)STARPU_VARIABLE_GET_PTR(descr[0]);
double *v_src = (double *)STARPU_VARIABLE_GET_PTR(descr[1]);
cublasaxpy(1, (double)1.0, v_src, 1, v_dst, 1);
cudaStreamSynchronize(starpu_cuda_get_local_stream());
}
struct starpu_codelet accumulate_variable_cl =
{
.cpu_funcs = { accumulate_variable_cpu},
.cuda_funcs = { accumulate_variable_cuda},
.nbuffers = 1,
}

and attaches them as reduction methods for its handle dtq:

starpu_variable_data_register(&dtq_handle, -1, NULL, sizeof(type));
starpu_data_set_reduction_methods(dtq_handle,
&accumulate_variable_cl, &bzero_variable_cl);

and dtq_handle can now be used in mode STARPU_REDUX for the dot products with partitioned vectors:

for (b = 0; b < nblocks; b++)
starpu_insert_task(&dot_kernel_cl,
STARPU_REDUX, dtq_handle,
STARPU_R, starpu_data_get_sub_data(v1, 1, b),
STARPU_R, starpu_data_get_sub_data(v2, 1, b),
0);

During registration, we have here provided NULL, i.e. there is no initial value to be taken into account during reduction. StarPU will thus only take into account the contributions from the tasks dot_kernel_cl. Also, it will not allocate any memory for dtq_handle before tasks dot_kernel_cl are ready to run.

If another dot product has to be performed, one could unregister dtq_handle, and re-register it. But one can also call starpu_data_invalidate_submit() with the parameter dtq_handle, which will clear all data from the handle, thus resetting it back to the initial status register(NULL).

The example cg also uses reduction for the blocked gemv kernel, leading to yet more relaxed dependencies and more parallelism.

STARPU_REDUX can also be passed to starpu_mpi_insert_task() in the MPI case. That will however not produce any MPI communication, but just pass STARPU_REDUX to the underlying starpu_insert_task(). It is up to the application to call starpu_mpi_redux_data(), which posts tasks that will reduce the partial results among MPI nodes into the MPI node which owns the data. For instance, some hypothetical application which collects partial results into data res, then uses it for other computation, before looping again with a new reduction:

for (i = 0; i < 100; i++) {
starpu_mpi_insert_task(MPI_COMM_WORLD, &init_res, STARPU_W, res, 0);
starpu_mpi_insert_task(MPI_COMM_WORLD, &work, STARPU_RW, A,
STARPU_R, B, STARPU_REDUX, res, 0);
starpu_mpi_redux_data(MPI_COMM_WORLD, res);
starpu_mpi_insert_task(MPI_COMM_WORLD, &work2, STARPU_RW, B, STARPU_R, res, 0);
}

Temporary Buffers

There are two kinds of temporary buffers: temporary data which just pass results from a task to another, and scratch data which are needed only internally by tasks.

Temporary Data

Data can sometimes be entirely produced by a task, and entirely consumed by another task, without the need for other parts of the application to access it. In such case, registration can be done without prior allocation, by using the special memory node number -1, and passing a zero pointer. StarPU will actually allocate memory only when the task creating the content gets scheduled, and destroy it on unregistration.

In addition to that, it can be tedious for the application to have to unregister the data, since it will not use its content anyway. The unregistration can be done lazily by using the function starpu_data_unregister_submit(), which will record that no more tasks accessing the handle will be submitted, so that it can be freed as soon as the last task accessing it is over.

The following code examplifies both points: it registers the temporary data, submits three tasks accessing it, and records the data for automatic unregistration.

starpu_vector_data_register(&handle, -1, 0, n, sizeof(float));
starpu_insert_task(&produce_data, STARPU_W, handle, 0);
starpu_insert_task(&compute_data, STARPU_RW, handle, 0);
starpu_insert_task(&summarize_data, STARPU_R, handle, STARPU_W, result_handle, 0);
starpu_data_unregister_submit(handle);

The application may also want to see the temporary data initialized on the fly before being used by the task. This can be done by using starpu_data_set_reduction_methods() to set an initialization codelet (no redux codelet is needed).

Scratch Data

Some kernels sometimes need temporary data to achieve the computations, i.e. a workspace. The application could allocate it at the start of the codelet function, and free it at the end, but that would be costly. It could also allocate one buffer per worker (similarly to How To Initialize A Computation Library Once For Each Worker?), but that would make them systematic and permanent. A more optimized way is to use the data access mode STARPU_SCRATCH, as examplified below, which provides per-worker buffers without content consistency.

starpu_vector_data_register(&workspace, -1, 0, sizeof(float));
for (i = 0; i < N; i++)
starpu_insert_task(&compute, STARPU_R, input[i],
STARPU_SCRATCH, workspace, STARPU_W, output[i], 0);

StarPU will make sure that the buffer is allocated before executing the task, and make this allocation per-worker: for CPU workers, notably, each worker has its own buffer. This means that each task submitted above will actually have its own workspace, which will actually be the same for all tasks running one after the other on the same worker. Also, if for instance GPU memory becomes scarce, StarPU will notice that it can free such buffers easily, since the content does not matter.

The example examples/pi uses scratches for some temporary buffer.

Parallel Tasks

StarPU can leverage existing parallel computation libraries by the means of parallel tasks. A parallel task is a task which gets worked on by a set of CPUs (called a parallel or combined worker) at the same time, by using an existing parallel CPU implementation of the computation to be achieved. This can also be useful to improve the load balance between slow CPUs and fast GPUs: since CPUs work collectively on a single task, the completion time of tasks on CPUs become comparable to the completion time on GPUs, thus relieving from granularity discrepancy concerns. hwloc support needs to be enabled to get good performance, otherwise StarPU will not know how to better group cores.

Two modes of execution exist to accomodate with existing usages.

Fork-mode Parallel Tasks

In the Fork mode, StarPU will call the codelet function on one of the CPUs of the combined worker. The codelet function can use starpu_combined_worker_get_size() to get the number of threads it is allowed to start to achieve the computation. The CPU binding mask for the whole set of CPUs is already enforced, so that threads created by the function will inherit the mask, and thus execute where StarPU expected, the OS being in charge of choosing how to schedule threads on the corresponding CPUs. The application can also choose to bind threads by hand, using e.g. sched_getaffinity to know the CPU binding mask that StarPU chose.

For instance, using OpenMP (full source is available in examples/openmp/vector_scal.c):

void scal_cpu_func(void *buffers[], void *_args)
{
unsigned i;
float *factor = _args;
struct starpu_vector_interface *vector = buffers[0];
unsigned n = STARPU_VECTOR_GET_NX(vector);
float *val = (float *)STARPU_VECTOR_GET_PTR(vector);
#pragma omp parallel for num_threads(starpu_combined_worker_get_size())
for (i = 0; i < n; i++)
val[i] *= *factor;
}
static struct starpu_codelet cl =
{
.modes = { STARPU_RW },
.where = STARPU_CPU,
.type = STARPU_FORKJOIN,
.max_parallelism = INT_MAX,
.cpu_funcs = {scal_cpu_func},
.nbuffers = 1,
};

Other examples include for instance calling a BLAS parallel CPU implementation (see examples/mult/xgemm.c).

SPMD-mode Parallel Tasks

In the SPMD mode, StarPU will call the codelet function on each CPU of the combined worker. The codelet function can use starpu_combined_worker_get_size() to get the total number of CPUs involved in the combined worker, and thus the number of calls that are made in parallel to the function, and starpu_combined_worker_get_rank() to get the rank of the current CPU within the combined worker. For instance:

static void func(void *buffers[], void *args)
{
unsigned i;
float *factor = _args;
struct starpu_vector_interface *vector = buffers[0];
unsigned n = STARPU_VECTOR_GET_NX(vector);
float *val = (float *)STARPU_VECTOR_GET_PTR(vector);
/* Compute slice to compute */
unsigned m = starpu_combined_worker_get_size();
unsigned j = starpu_combined_worker_get_rank();
unsigned slice = (n+m-1)/m;
for (i = j * slice; i < (j+1) * slice && i < n; i++)
val[i] *= *factor;
}
static struct starpu_codelet cl =
{
.modes = { STARPU_RW },
.where = STARP_CPU,
.type = STARPU_SPMD,
.max_parallelism = INT_MAX,
.cpu_funcs = { func},
.nbuffers = 1,
}

Of course, this trivial example will not really benefit from parallel task execution, and was only meant to be simple to understand. The benefit comes when the computation to be done is so that threads have to e.g. exchange intermediate results, or write to the data in a complex but safe way in the same buffer.

Parallel Tasks Performance

To benefit from parallel tasks, a parallel-task-aware StarPU scheduler has to be used. When exposed to codelets with a flag STARPU_FORKJOIN or STARPU_SPMD, the schedulers pheft (parallel-heft) and peager (parallel eager) will indeed also try to execute tasks with several CPUs. It will automatically try the various available combined worker sizes (making several measurements for each worker size) and thus be able to avoid choosing a large combined worker if the codelet does not actually scale so much.

Combined Workers

By default, StarPU creates combined workers according to the architecture structure as detected by hwloc. It means that for each object of the hwloc topology (NUMA node, socket, cache, ...) a combined worker will be created. If some nodes of the hierarchy have a big arity (e.g. many cores in a socket without a hierarchy of shared caches), StarPU will create combined workers of intermediate sizes. The variable STARPU_SYNTHESIZE_ARITY_COMBINED_WORKER permits to tune the maximum arity between levels of combined workers.

The combined workers actually produced can be seen in the output of the tool starpu_machine_display (the environment variable STARPU_SCHED has to be set to a combined worker-aware scheduler such as pheft or peager).

Concurrent Parallel Tasks

Unfortunately, many environments and librairies do not support concurrent calls.

For instance, most OpenMP implementations (including the main ones) do not support concurrent pragma omp parallel statements without nesting them in another pragma omp parallel statement, but StarPU does not yet support creating its CPU workers by using such pragma.

Other parallel libraries are also not safe when being invoked concurrently from different threads, due to the use of global variables in their sequential sections for instance.

The solution is then to use only one combined worker at a time. This can be done by setting the field starpu_conf::single_combined_worker to 1, or setting the environment variable STARPU_SINGLE_COMBINED_WORKER to 1. StarPU will then run only one parallel task at a time (but other CPU and GPU tasks are not affected and can be run concurrently). The parallel task scheduler will however still however still try varying combined worker sizes to look for the most efficient ones.

applications

StarPU provides several tools to help debugging aplications. Execution traces can be generated and displayed graphically, see Generating Traces With FxT.

Some gdb helpers are also provided to show the whole StarPU state:

(gdb) source tools/gdbinit
(gdb) help starpu

Valgrind can be used on StarPU: valgrind.h just needs to be found at ./configure time, to tell valgrind about some known false positives and disable host memory pinning. Other known false positives can be suppressed by giving the suppression files in tools/valgrind/ *.suppr to valgrind's –suppressions option.

The STARPU_DISABLE_KERNELS environment variable can also be set to 1 to make StarPU do everything (schedule tasks, transfer memory, etc.) except actually calling the application-provided kernel functions, i.e. the computation will not happen. This permits to quickly check that the task scheme is working properly.

The Temanejo task debugger can also be used, see Using The Temanejo Task Debugger.

The Multiformat Interface

It may be interesting to represent the same piece of data using two different data structures: one that would only be used on CPUs, and one that would only be used on GPUs. This can be done by using the multiformat interface. StarPU will be able to convert data from one data structure to the other when needed. Note that the scheduler dmda is the only one optimized for this interface. The user must provide StarPU with conversion codelets:

#define NX 1024
struct point array_of_structs[NX];
starpu_data_handle_t handle;
/*
* The conversion of a piece of data is itself a task, though it is created,
* submitted and destroyed by StarPU internals and not by the user. Therefore,
* we have to define two codelets.
* Note that for now the conversion from the CPU format to the GPU format has to
* be executed on the GPU, and the conversion from the GPU to the CPU has to be
* executed on the CPU.
*/
#ifdef STARPU_USE_OPENCL
void cpu_to_opencl_opencl_func(void *buffers[], void *args);
struct starpu_codelet cpu_to_opencl_cl = {
.where = STARPU_OPENCL,
.opencl_funcs = { cpu_to_opencl_opencl_func},
.nbuffers = 1,
.modes = { STARPU_RW }
};
void opencl_to_cpu_func(void *buffers[], void *args);
struct starpu_codelet opencl_to_cpu_cl = {
.where = STARPU_CPU,
.cpu_funcs = { opencl_to_cpu_func},
.nbuffers = 1,
.modes = { STARPU_RW }
};
#endif
struct starpu_multiformat_data_interface_ops format_ops = {
#ifdef STARPU_USE_OPENCL
.opencl_elemsize = 2 * sizeof(float),
.cpu_to_opencl_cl = &cpu_to_opencl_cl,
.opencl_to_cpu_cl = &opencl_to_cpu_cl,
#endif
.cpu_elemsize = 2 * sizeof(float),
...
};
starpu_multiformat_data_register(handle, 0, &array_of_structs, NX, &format_ops);

Kernels can be written almost as for any other interface. Note that STARPU_MULTIFORMAT_GET_CPU_PTR shall only be used for CPU kernels. CUDA kernels must use STARPU_MULTIFORMAT_GET_CUDA_PTR, and OpenCL kernels must use STARPU_MULTIFORMAT_GET_OPENCL_PTR. STARPU_MULTIFORMAT_GET_NX may be used in any kind of kernel.

static void
multiformat_scal_cpu_func(void *buffers[], void *args)
{
struct point *aos;
unsigned int n;
aos = STARPU_MULTIFORMAT_GET_CPU_PTR(buffers[0]);
n = STARPU_MULTIFORMAT_GET_NX(buffers[0]);
...
}
extern "C" void multiformat_scal_cuda_func(void *buffers[], void *_args)
{
unsigned int n;
struct struct_of_arrays *soa;
soa = (struct struct_of_arrays *) STARPU_MULTIFORMAT_GET_CUDA_PTR(buffers[0]);
n = STARPU_MULTIFORMAT_GET_NX(buffers[0]);
...
}

A full example may be found in examples/basic_examples/multiformat.c.

Using The Driver API

Running Drivers

int ret;
struct starpu_driver = {
.type = STARPU_CUDA_WORKER,
.id.cuda_id = 0
};
ret = starpu_driver_init(&d);
if (ret != 0)
error();
while (some_condition) {
ret = starpu_driver_run_once(&d);
if (ret != 0)
error();
}
ret = starpu_driver_deinit(&d);
if (ret != 0)

To add a new kind of device to the structure starpu_driver, one needs to:

  1. Add a member to the union starpu_driver::id
  2. Modify the internal function _starpu_launch_drivers() to make sure the driver is not always launched.
  3. Modify the function starpu_driver_run() so that it can handle another kind of architecture.
  4. Write the new function _starpu_run_foobar() in the corresponding driver.

Defining A New Scheduling Policy

A full example showing how to define a new scheduling policy is available in the StarPU sources in the directory examples/scheduler/.

See Scheduling Policy

static struct starpu_sched_policy dummy_sched_policy = {
.init_sched = init_dummy_sched,
.deinit_sched = deinit_dummy_sched,
.add_workers = dummy_sched_add_workers,
.remove_workers = dummy_sched_remove_workers,
.push_task = push_task_dummy,
.push_prio_task = NULL,
.pop_task = pop_task_dummy,
.post_exec_hook = NULL,
.pop_every_task = NULL,
.policy_name = "dummy",
.policy_description = "dummy scheduling strategy"
};

On-GPU Rendering

Graphical-oriented applications need to draw the result of their computations, typically on the very GPU where these happened. Technologies such as OpenGL/CUDA interoperability permit to let CUDA directly work on the OpenGL buffers, making them thus immediately ready for drawing, by mapping OpenGL buffer, textures or renderbuffer objects into CUDA. CUDA however imposes some technical constraints: peer memcpy has to be disabled, and the thread that runs OpenGL has to be the one that runs CUDA computations for that GPU.

To achieve this with StarPU, pass the option --disable-cuda-memcpy-peer to ./configure (TODO: make it dynamic), OpenGL/GLUT has to be initialized first, and the interoperability mode has to be enabled by using the field starpu_conf::cuda_opengl_interoperability, and the driver loop has to be run by the application, by using the field starpu_conf::not_launched_drivers to prevent StarPU from running it in a separate thread, and by using starpu_driver_run() to run the loop. The examples gl_interop and gl_interop_idle show how it articulates in a simple case, where rendering is done in task callbacks. The former uses glutMainLoopEvent to make GLUT progress from the StarPU driver loop, while the latter uses glutIdleFunc to make StarPU progress from the GLUT main loop.

Then, to use an OpenGL buffer as a CUDA data, StarPU simply needs to be given the CUDA pointer at registration, for instance:

/* Get the CUDA worker id */
for (workerid = 0; workerid < starpu_worker_get_count(); workerid++)
if (starpu_worker_get_type(workerid) == STARPU_CUDA_WORKER)
break;
/* Build a CUDA pointer pointing at the OpenGL buffer */
cudaGraphicsResourceGetMappedPointer((void**)&output, &num_bytes, resource);
/* And register it to StarPU */
starpu_vector_data_register(&handle, starpu_worker_get_memory_node(workerid),
output, num_bytes / sizeof(float4), sizeof(float4));
/* The handle can now be used as usual */
starpu_insert_task(&cl, STARPU_RW, handle, 0);
/* ... */
/* This gets back data into the OpenGL buffer */
starpu_data_unregister(handle);

and display it e.g. in the callback function.

Defining A New Data Interface

Let's define a new data interface to manage complex numbers.

/* interface for complex numbers */
struct starpu_complex_interface
{
double *real;
double *imaginary;
int nx;
};

Registering such a data to StarPU is easily done using the function starpu_data_register(). The last parameter of the function, interface_complex_ops, will be described below.

void starpu_complex_data_register(starpu_data_handle_t *handle,
unsigned home_node, double *real, double *imaginary, int nx)
{
struct starpu_complex_interface complex =
{
.real = real,
.imaginary = imaginary,
.nx = nx
};
if (interface_complex_ops.interfaceid == STARPU_UNKNOWN_INTERFACE_ID)
{
interface_complex_ops.interfaceid = starpu_data_interface_get_next_id();
}
starpu_data_register(handleptr, home_node, &complex, &interface_complex_ops);
}

Different operations need to be defined for a data interface through the type starpu_data_interface_ops. We only define here the basic operations needed to run simple applications. The source code for the different functions can be found in the file examples/interface/complex_interface.c.

static struct starpu_data_interface_ops interface_complex_ops =
{
.register_data_handle = complex_register_data_handle,
.allocate_data_on_node = complex_allocate_data_on_node,
.copy_methods = &complex_copy_methods,
.get_size = complex_get_size,
.footprint = complex_footprint,
.interfaceid = STARPU_UNKNOWN_INTERFACE_ID,
.interface_size = sizeof(struct starpu_complex_interface),
};

Functions need to be defined to access the different fields of the complex interface from a StarPU data handle.

double *starpu_complex_get_real(starpu_data_handle_t handle)
{
struct starpu_complex_interface *complex_interface =
(struct starpu_complex_interface *) starpu_data_get_interface_on_node(handle, 0);
return complex_interface->real;
}
double *starpu_complex_get_imaginary(starpu_data_handle_t handle);
int starpu_complex_get_nx(starpu_data_handle_t handle);

Similar functions need to be defined to access the different fields of the complex interface from a void * pointer to be used within codelet implemetations.

#define STARPU_COMPLEX_GET_REAL(interface) \
(((struct starpu_complex_interface *)(interface))->real)
#define STARPU_COMPLEX_GET_IMAGINARY(interface) \
(((struct starpu_complex_interface *)(interface))->imaginary)
#define STARPU_COMPLEX_GET_NX(interface) \
(((struct starpu_complex_interface *)(interface))->nx)

Complex data interfaces can then be registered to StarPU.

double real = 45.0;
double imaginary = 12.0;
starpu_complex_data_register(&handle1, 0, &real, &imaginary, 1);
starpu_insert_task(&cl_display, STARPU_R, handle1, 0);

and used by codelets.

void display_complex_codelet(void *descr[], __attribute__ ((unused)) void *_args)
{
int nx = STARPU_COMPLEX_GET_NX(descr[0]);
double *real = STARPU_COMPLEX_GET_REAL(descr[0]);
double *imaginary = STARPU_COMPLEX_GET_IMAGINARY(descr[0]);
int i;
for(i=0 ; i<nx ; i++)
{
fprintf(stderr, "Complex[%d] = %3.2f + %3.2f i\n", i, real[i], imaginary[i]);
}
}

The whole code for this complex data interface is available in the directory examples/interface/.

Setting The Data Handles For A Task

The number of data a task can manage is fixed by the environment variable STARPU_NMAXBUFS which has a default value which can be changed through the configure option --enable-maxbuffers.

However, it is possible to define tasks managing more data by using the field starpu_task::dyn_handles when defining a task and the field starpu_codelet::dyn_modes when defining the corresponding codelet.

enum starpu_data_access_mode modes[STARPU_NMAXBUFS+1] = {
STARPU_R, STARPU_R, ...
};
struct starpu_codelet dummy_big_cl =
{
.cuda_funcs = {dummy_big_kernel},
.opencl_funcs = {dummy_big_kernel},
.cpu_funcs = {dummy_big_kernel},
.nbuffers = STARPU_NMAXBUFS+1,
.dyn_modes = modes
};
task = starpu_task_create();
task->cl = &dummy_big_cl;
task->dyn_handles = malloc(task->cl->nbuffers * sizeof(starpu_data_handle_t));
for(i=0 ; i<task->cl->nbuffers ; i++)
{
task->dyn_handles[i] = handle;
}
starpu_task_submit(task);
starpu_data_handle_t *handles = malloc(dummy_big_cl.nbuffers * sizeof(starpu_data_handle_t));
for(i=0 ; i<dummy_big_cl.nbuffers ; i++)
{
handles[i] = handle;
}
starpu_insert_task(&dummy_big_cl,
STARPU_VALUE, &dummy_big_cl.nbuffers, sizeof(dummy_big_cl.nbuffers),
STARPU_DATA_ARRAY, handles, dummy_big_cl.nbuffers,
0);

The whole code for this complex data interface is available in the directory examples/basic_examples/dynamic_handles.c.

Specifying a target node for task data

When executing a task on a GPU for instance, StarPU would normally copy all the needed data for the tasks on the embedded memory of the GPU. It may however happen that the task kernel would rather have some of the datas kept in the main memory instead of copied in the GPU, a pivoting vector for instance. This can be achieved by setting the starpu_codelet::specific_nodes flag to 1, and then fill the starpu_codelet::nodes array (or starpu_codelet::dyn_nodes when starpu_codelet::nbuffers is greater than STARPU_NMAXBUFS) with the node numbers where data should be copied to, or -1 to let StarPU copy it to the memory node where the task will be executed. For instance, with the following codelet:

struct starpu_codelet cl =
{
.cuda_funcs = { kernel},
.nbuffers = 2,
.modes = {STARPU_RW, STARPU_RW},
.specific_nodes = 1,
.nodes = {0, -1},
};

the first data of the task will be kept in the main memory, while the second data will be copied to the CUDA GPU as usual.

)

This function notifies UI than the task have been planed to run from start to end, on computation-core.

void starpu_top_debug_log ( const char *  message)

This function is useful in debug mode. The starpu developper doesn't need to check if the debug mode is active. This is checked by starpu_top itsefl. It just send a message to display by UI.

void starpu_top_debug_lock ( const char *  message)

This function is useful in debug mode. The starpu developper doesn't need to check if the debug mode is active. This is checked by starpu_top itsefl. It send a message and wait for a continue message from UI to return. The lock (wich create a stop-point) should be called only by the main thread. Calling it from more than one thread is not supported.

FFT Support

StarPU provides libstarpufft, a library whose design is very similar to both fftw and cufft, the difference being that it takes benefit from both CPUs and GPUs. It should however be noted that GPUs do not have the same precision as CPUs, so the results may different by a negligible amount.

Different precisions are available, namely float, double and long double precisions, with the following fftw naming conventions:

  • double precision structures and functions are named e.g. starpufft_execute()
  • float precision structures and functions are named e.g. starpufftf_execute()
  • long double precision structures and functions are named e.g. starpufftl_execute()

The documentation below is given with names for double precision, replace starpufft_ with starpufftf_ or starpufftl_ as appropriate.

Only complex numbers are supported at the moment.

The application has to call starpu_init() before calling starpufft functions.

Either main memory pointers or data handles can be provided.

All functions are defined in FFT Support.

Compilation

The flags required to compile or link against the FFT library are accessible with the following commands:

$ pkg-config --cflags starpufft-1.1  # options for the compiler
$ pkg-config --libs starpufft-1.1    # options for the linker

Also pass the option –static if the application is to be linked statically.

Scheduling Contexts

TODO: improve!

General Ideas

Scheduling contexts represent abstracts sets of workers that allow the programmers to control the distribution of computational resources (i.e. CPUs and GPUs) to concurrent parallel kernels. The main goal is to minimize interferences between the execution of multiple parallel kernels, by partitioning the underlying pool of workers using contexts.

Creating A Context

By default, the application submits tasks to an initial context, which disposes of all the computation resources available to StarPU (all the workers). If the application programmer plans to launch several parallel kernels simultaneously, by default these kernels will be executed within this initial context, using a single scheduler policy(see Task Scheduling Policy). Meanwhile, if the application programmer is aware of the demands of these kernels and of the specificity of the machine used to execute them, the workers can be divided between several contexts. These scheduling contexts will isolate the execution of each kernel and they will permit the use of a scheduling policy proper to each one of them.

Scheduling Contexts may be created in two ways: either the programmers indicates the set of workers corresponding to each context (providing he knows the identifiers of the workers running within StarPU), or the programmer does not provide any worker list and leaves the Hypervisor assign workers to each context according to their needs (Scheduling Context Hypervisor)

Both cases require a call to the function starpu_sched_ctx_create, which requires as input the worker list (the exact list or a NULL pointer) and the scheduling policy. The latter one can be a character list corresponding to the name of a StarPU predefined policy or the pointer to a custom policy. The function returns an identifier of the context created which you will use to indicate the context you want to submit the tasks to.

/* the list of resources the context will manage */
int workerids[3] = {1, 3, 10};
/* indicate the scheduling policy to be used within the context, the list of
workers assigned to it, the number of workers, the name of the context */
int id_ctx = starpu_sched_ctx_create("dmda", workerids, 3, "my_ctx");
/* let StarPU know that the following tasks will be submitted to this context */
starpu_sched_ctx_set_task_context(id);
/* submit the task to StarPU */
starpu_task_submit(task);

Note: Parallel greedy and parallel heft scheduling policies do not support the existence of several disjoint contexts on the machine. Combined workers are constructed depending on the entire topology of the machine, not only the one belonging to a context.

Modifying A Context

A scheduling context can be modified dynamically. The applications may change its requirements during the execution and the programmer can add additional workers to a context or remove if no longer needed. In the following example we have two scheduling contexts sched_ctx1 and sched_ctx2. After executing a part of the tasks some of the workers of sched_ctx1 will be moved to context sched_ctx2.

/* the list of ressources that context 1 will give away */
int workerids[3] = {1, 3, 10};
/* add the workers to context 1 */
starpu_sched_ctx_add_workers(workerids, 3, sched_ctx2);
/* remove the workers from context 2 */
starpu_sched_ctx_remove_workers(workerids, 3, sched_ctx1);

Submitting Tasks To A Context

The application may submit tasks to several contexts either simultaneously or sequnetially. If several threads of submission are used the function starpu_sched_ctx_set_context may be called just before starpu_task_submit. Thus StarPU considers that the current thread will submit tasks to the coresponding context.

When the application may not assign a thread of submission to each context, the id of the context must be indicated by using the function starpu_task_submit_to_ctx or the field STARPU_SCHED_CTX for starpu_insert_task.

Deleting A Context

When a context is no longer needed it must be deleted. The application can indicate which context should keep the resources of a deleted one. All the tasks of the context should be executed before doing this. Thus, the programmer may use either a barrier and then delete the context directly, or just indicate that other tasks will not be submitted later on to the context (such that when the last task is executed its workers will be moved to the inheritor) and delete the context at the end of the execution (when a barrier will be used eventually).

/* when the context 2 is deleted context 1 inherits its resources */
starpu_sched_ctx_set_inheritor(sched_ctx2, sched_ctx1);
/* submit tasks to context 2 */
for (i = 0; i < ntasks; i++)
starpu_task_submit_to_ctx(task[i],sched_ctx2);
/* indicate that context 2 finished submitting and that */
/* as soon as the last task of context 2 finished executing */
/* its workers can be moved to the inheritor context */
starpu_sched_ctx_finished_submit(sched_ctx1);
/* wait for the tasks of both contexts to finish */
starpu_task_wait_for_all();
/* delete context 2 */
starpu_sched_ctx_delete(sched_ctx2);
/* delete context 1 */
starpu_sched_ctx_delete(sched_ctx1);

Emptying A Context

A context may have no resources at the begining or at a certain moment of the execution. Task can still be submitted to these contexts and they will be executed as soon as the contexts will have resources. A list of tasks pending to be executed is kept and when workers are added to the contexts these tasks start being submitted. However, if resources are never allocated to the context the program will not terminate. If these tasks have low priority the programmer can forbid the application to submit them by calling the function starpu_sched_ctx_stop_task_submission().

Contexts Sharing Workers

Contexts may share workers when a single context cannot execute efficiently enough alone on these workers or when the application decides to express a hierarchy of contexts. The workers apply an alogrithm of ``Round-Robin'' to chose the context on which they will ``pop'' next. By using the function starpu_sched_ctx_set_turn_to_other_ctx, the programmer can impose the workerid to ``pop'' in the context sched_ctx_id next.

Compiling OpenCL kernels

Source codes for OpenCL kernels can be stored in a file or in a string. StarPU provides functions to build the program executable for each available OpenCL device as a cl_program object. This program executable can then be loaded within a specific queue as explained in the next section. These are only helpers, Applications can also fill a starpu_opencl_program array by hand for more advanced use (e.g. different programs on the different OpenCL devices, for relocation purpose for instance).
