dieharder

Random-number generator test front-end

dieharder is a fairly involved random number/uniform deviate generator tester. It can either test any of its many prebuilt and linked generators (basically all of those in the GNU Scientific Library plus any others I've been able to find) or a potentially random dataset in a file. With file input, it can test either N-bit bitstrings (with N user specifiable) or (double precision) floating point numbers in the range [0.0,1.0) (uniform deviates). It is thus suitable for use in testing both software RNG's and hardware RNG's. This package provides the command-line frontend.
