dSFMT
2.2
|
This is double precision SIMD oriented Fast Mersenne Twister pseudorandom number generator (dSFMT). This program is based on the IEEE Standard for Binary Floating-Point Arithmetic (ANSI/IEEE Std 754-1985) format.
dSFMT ver. 2.xx is completely different from dSFMT ver. 1.xx. The recursion formula is changed. And the output sequences are changed.
This version uses structure of C language. Don't use different DSFMT_MEXP for compiling dSFMT.c and your program.
This Project provides pseudorandom number generators of various Mersenne Prime Period: from 2521-1 to 2216091-1.
To get dSFMT which has the period of 2521-1, you have to specify -DMEXP=521 as a compile option. For example,
gcc -DDSFMT_MEXP=521 -msse2 -DHAVE_SSE2 -c dSFMT.c
will make dSFMT which has the period of 2521-1 and is optimized for SSE2.
See How to compile to compile your program with SFMT optimized for SIMD.
Old names init_gen_rand, init_by_array, etc. are also defined unless you define DSFMT_DO_NOT_USE_OLD_NAMES.
