I need to test a large number of consecutive numbers for finding primes which fit on several hundreds of bits.
Most actual implementations are for CUDA, but I don't have a recent nVidia card.
I tried to dial for this implementation. The guy told me he will send it, but I didn't had any answer.
I don't mind if basic computations are done serially, because I'm expecting to perform miller-rabin tests in parallel. I need more speed because, it take 25min for GMP to find a 32 Ko long prime on a last gen i7-core.
I don't mind about the language. I've been looking for C, as well for writing the kernel in Python or PHP.
