This may be a dumb question...Do video cards contribute anything at all to doing integer calculations? Video cards now a day are pretty powerful.

BOINC v6 is in development with CUDA (gpu) but need also apps from the projects, you can only run folding@home (non BOINC project yet) with an gpu client at this time.

IIRC CUDA is specific to nVidia. I think there is something similar for ATI cards but I can't say for sure.

And how big of an effect or difference would you say that a video cards GPU would make on such a task as PrimeGrid if it were implemented for this project. Or for the one that it is already working for?

It would potentially be very good for factorization, it would be awful for prime determination.

GPUs are about having lots of small processors that all work very close together to do very fast of the same floating point operations over and over again. So your algorithm needs to be very parallizable and fit the methods in which a GPU runs.

I could imagine that certain types of factorization would fit this really nicely however I've never seen a working algorithm for such a thing, but all the prime determination algorithms I know would be very very poor on a GPU.

PS3Grid/GPUGrid managed to compile BOINC and their application to run on GPU's. Right now there's only a client for 64-bit linux.
