[erlang-questions] [ANN] xorshift1024* PRNG for Erlang

[Kenji Rikitake]

I've released one more non-cryptographic random number generator
implementations for Erlang. This is still in the alpha phase, so bug
reports and enhancements welcome.

xorshift1024* (exs1024)
https://github.com/jj1bdx/exs1024/

xorshift+ and xorshift* pseudo random number generators (PRNGs) look
 promising as faster and more compact alternatives to Mersenne Twister PRNGs
 for 64-bit execution environments. 

The implementations is in Erlang without NIFs, with the MIT license.

xorshift1024* generates 64-bit integer sequences.

xorshift1024* has sixteen (16) 64-bit integers for the internal state,
and the period is (2^1024-1), much longer than tinymt-erlang, and
comparatively a good alternative against sfmt-erlang.  The execution
time of exs1024 is ~x2 of random module on OTP 17.3 with HiPE on OS X
x86_64 and FreeBSD amd64 environments.

See http://xorshift.di.unimi.it/ for the further details of xorshift+ and
xorshift* algorithms.
