mersenne-random: Generate high quality pseudorandom numbers using a SIMD Fast Mersenne Twister

[ bsd3, library, math, system ] [ Propose Tags ] [ Report a vulnerability ]

The Mersenne twister is a pseudorandom number generator developed by Makoto Matsumoto and Takuji Nishimura that is based on a matrix linear recurrence over a finite binary field. It provides for fast generation of very high quality pseudorandom numbers

This library uses SFMT, the SIMD-oriented Fast Mersenne Twister, a variant of Mersenne Twister that is much faster than the original. It is designed to be fast when it runs on 128-bit SIMD. It can be compiled with either SSE2 and PowerPC AltiVec support, to take advantage of these instructions.

cabal install -fuse_sse2

On an x86 system, for performance win.

By default the period of the function is 2^19937-1, however, you can compile in other defaults. Note that this algorithm on its own is not cryptographically secure.

For more information about the algorithm and implementation, see the SFMT homepage,
