randlc, a Fortran90 code which implements a version of the random number generator (RNG) used by the NAS Parallel Benchmarks.
The generator has the form
X(K+1) = A * X(K) mod 2^46
where the suggested value of the multiplier A is 5^13 = 1220703125.
This scheme generates 2^44 numbers before repeating.
