What is this about?
This repository aims at providing a modular and version controlled implementation of several
pseudo random number generation (PRNG) algorithms. All implementations are done in C, for
convenience with respect to integer arithmetics, and made available to Fortran via the
The first algorithm that was implemented in this repository is the Mersenne Twister. Now, the threefry PRNG is also available.
