The objective of the new + version is to combine the current random number generators (RNGs) into + a single library so that a user can use all of them in a single program + at a same time. + + The user now is able to and needs to specify the type of RNG when a + random number stream is initialized. We add one integer argument + rng_type to the front of the argument list of the function init_sprng. + + int *init_sprng(int rng_type, + int stream_number, int nstreams, int seed, int rng_parameter) + SPRNG_POINTER init_sprng(integer rng_type, + integer streamnum, integer nstreams, + integer seed, integer param) + + + User can sprcify one of the follows for rng_type: + SPRNG_LFG + SPRNG_LCG + SPRNG_LCG64 + SPRNG_CMRG + SPRNG_MLFG + SPRNG_PMLCG + The following macros are added to sprng.h and sprng_f.h: + + #define SPRNG_LFG 0 + #define SPRNG_LCG 1 + #define SPRNG_LCG64 2 + #define SPRNG_CMRG 3 + #define SPRNG_MLFG 4 + #define SPRNG_PMLCG 5 + + For simple interface, a user can only have one random number stream at + one time since he doesn't specify stream ID. + The default generator is "SPRNG_LFG". + User still can change RNG at runtime by calling init_sprng: + int *init_sprng(int rng_type, + int seed, int rng_parameter) + SPRNG_POINTER init_sprng(integer rng_type, + integer seed, integer param) + --- a/src/Makefile.am +++ b/src/Makefile.am View it on GitLab: https://salsa.debian.org/med-team/tree-puzzle/commit/2dce726f58c9cbc70d83a05d3b8f954e83bd2807 -- View it on GitLab: https://salsa.debian.org/med-team/tree-puzzle/commit/2dce726f58c9cbc70d83a05d3b8f954e83bd2807 You're receiving this email because of your account on salsa.debian.org.
