This modification of the Lagged Fibonacci Generator is performed in order to avoid certain correlations that are observed in the unmodified generator. The period of this generator is \eqn{2^31(2^l-1)} where \eqn{l} is the lag. For the default generator with lag \eqn{l = 1279}, the period is approximately \eqn{2^1310}. The number of distinct streams available is \eqn{2^{31(l-1)-1}}. For the default generator this gives \eqn{2^39648} distinct streams. The parameters to this generator are the values of the lags.

The value of \eqn{M} for this generator is \eqn{2^48}. Different random number streams are obtained by choosing different prime numbers as the addend \eqn{p}.

Streams differ due to differences in the 64 bit LCG. The period of this generator is around \eqn{2^219}. The number of distinct streams available is over \eqn{10^8}. The multiplier \eqn{a} for the 64 bit LCG is a parameter to this generator.

Install SPRNG 2.0 (http:/sprng.cs.fsu.edu). Note that the generator pmlcg requires libgmp but it provides an outdated version of gmp.h. Find the following line in sprng2.0/SRC/pmlcg/pmlcg.c: #include "gmp.h" and change it to #include to use the system header file. It won't compile otherwise. If you encounter problems compiling SPRNG 2.0, this note http://www.biostat.umn.edu/~nali/rsprng.html might be of help. I have also made available some precompiled SPRNG packages at http://www.biostat.umn.edu/~nali/SoftwareListing.html. 2. Install rsprng: R CMD INSTALL rsprng_version.tgz If the SPRNG header file and library file are in a non-standard path use, R CMD INSTALL --configure-args=--with-sprng=/path/to/sprng rsprng_version.tgz The header files of SPRNG are ssumed to be in /path/to/sprng/include and the library .a files are in /path/to/sprng/lib. Alternative, one can also define environment variable SPRNG_ROOT to be the path (so that R CMD check can run). By default pointer checking for SPRNG is enabled, to disable it, pass '--configure-args=--disable-check-pointers' to 'R INSTALL'. libgmp.a is needed at linking. If it is installed in a non-standard location, you can specify it via: R CMD INSTALL --configure-args='--with-gmp=/path/to/libgmp.a'. rsprng/src/0000755000175100001440000000000011345336145012377 5ustar hornikusersrsprng/src/Makevars.in0000644000175100001440000000020411200434772014467 0ustar hornikusers# -*- Makefile -*- vim : ft = make # PVM library and header files PKG_CPPFLAGS = @DEFS@ @PKG_CPPFLAGS@ PKG_LIBS = @PKG_LIBS@ rsprng/src/Makevars.win0000644000175100001440000000017511343001201014646 0ustar hornikusers# -*- Makefile -*- vim : ft = make PKG_CPPFLAGS = -I$(LOCAL_SOFT)/include PKG_LIBS = -L$(LOCAL_SOFT)/lib -lsprng -lgmp rsprng/src/sprng_core.c0000644000175100001440000001105411205574127014704 0ustar hornikusers/* * Wrapper to core functions of sprng. * $Id: sprng_core.c,v 1.6 2003/04/17 19:08:05 nali Exp $ * **/ #include #include #include #include "sprng.h" #include /* * This struct is used to retrieve "rng_type" from the rng specific * "struct rngen".
