How about mulit-core or (perhaps more exciting) GPU and CUDA? I must

Obviously, cuBLAS is not an option here, so what is the safest route
for a novice parallel-programmer?
The problem with PRNG is that they are iterative in nature, and
maintain global states. They are therefore very hard to vectorize. A
GPU will not help. The GPU has hundreds of computational cores that
can run kernels, but you only get to utilize one.
Parallel PRNGs are an unsolved problem in computer science.
My parallel version of ziggurat works fine, with Fortran/OpenMP.
