%description
RANDOM (Fortran-90 pseudo-random number generator based on provably normal
number theory), based on the recently discovered class of provably normal
numbers -- see paper "Random Generators and Normal Numbers", by DHB and Richard
Crandall, in the papers directory. In particular, subroutine bcnrand generates a
sequence of IEEE 64-bit floating-point numbers uniformly in (0,1), with period
(if parameters are properly selected) = 2x3^32 = 3.7060404e15. It is completely
self-contained -- the required double-double arithmetic subroutines are included
in the Fortran-90 source file. The bcnrand routine is designed for simple
parallelization, yielding the same overall sequence as with a one-processor
program. Also included here is a memory-testing program based on the bcnrand
generator.
