Prof. Creel mentioned CUDA here
1) a while back.
The Nvidia forum has a recent thread that might be of interest:
Mixed Programming, Combining MPI and CUDA
MPI needs no explanation here, but CUDA might.
CUDA is Nvidia's development platform for their inexpensive, multi-processor, multi-register GPU's. These devices, found in video cards from many manufacturers, can be used as serious number crunchers. My card for example, a GT 9800, has 14 multiprocs and over 8,000, thirty-two bit registers. It can handle more than 12,000 simultaneous threads. And it's just a cheaper card (USD 120).
On my dual-core Intel, running eight simultaneous, near real-time FFT's, or ten repeated 4k x 4k matix, 3-vector multiples barely made the main board's cpu fan speed up. Although the boxes' total power consumption went from 250 to 320 Watts :)
