randlc, a Fortran77 code which implements a version of the pseudorandom number generator used by the NAS Parallel Benchmarks.
The generator has the form
X(K+1) = A * X(K) mod 2^46where the suggested value of the multiplier A is 5^13 = 1220703125.
This scheme generates 2^44 numbers before repeating.

randlc is available in a C version and a C++ version and a Fortran77 version and a Fortran90 version and a MATLAB version and an Octave version and a Python version.
ASA183, a Fortran77 library which implements the Wichman-Hill pseudorandom number generator.
NORMAL, a Fortran77 library which computes a sequence of pseudorandom normally distributed values.
UNIFORM, a Fortran77 library which computes elements of a pseudorandom sequence.
