I have an instrument at a NASA Lab (Jet Propulsion Laboratory) that does a huge amount of matrix crunching to create an image. It produces what is known as an image cube and provides the spatial and spectral information of the imaged object. A colleague suggested using a fast gaming card to run the vector multiplcaiton may be very fast since that is what a lot of graphics does I am looking for some suggestions on how to do this. Greg

I am looking for some suggestions on how to do this. There is a paper at Accelerator: simplified programming of graphics processing units for general-purpose uses via data-parallelism that is very similar to what I want to do.

There is a whole community dedicated to using the GPU for general purpose computing. Head on over to GPGPU.org and look through their material. I know a lot of people are using the GPU for image processing right now, so you should be able to find some good info. But yeah, for matrix and vector manipulation, GPU is the winner. Put those pipelines to work.
Also, I think there is more info on MS Accelerator on the GPGPU site.
