Also notably most of the acceleration of CUDA comes from its capacity for
fast 32 floating point operations. If you have to do anything with
precision higher than that, it isn't a great solution. I would be happy to
share the SOR Poisson solver I wrote with anyone though. Still in
pre-alpha, bit if it gave anyone a jump, I would be happy to give it away.
