Why aren't AP Units run on CUDA? Simply because no-one wrote a Cuda application for AP yet :) (well that I know of, perhaps they exist). I've chosen to focus on Multibeam with Cuda for the time being for several reasons: - relatively limited or sporadic AP task availability - a lot of questions about AP validation and blanking to be resolved. - focus on refining tools and techniques rather than immediate credit, for later use by any application (AP, GBT, other projects etc) - The OpenCL variants developed by others appear to be doing fine (while when I started on Cuda multibeam it was not doing 'fine') - Gives me as many field proven tools as possible when the time is right ( If done now, Cuda hosts would basically chew through all the issued AP in hours...), leading to, - ... Significant credit issues would need to be resolved first. That doesn't stop anyone making a Cuda enabled AP app, and AP integration is planned in x42 phase 2 (of 3), but for me that's lower priority than pulling ahead of the Cuda architecture release cycles for MB, and perfecting higher level tools/techniques.

Why aren't AP Units run on CUDA? Thanks Jason. I was just curious; being brand new to GPU crunching... I've also just re-attached to Einstein@Home. WOW over 4 Hrs to complete a WU there, (estimated), on my new card. I've given Einstein a low priority; so, only one WU for now. We'll see what happens with SETI Main and Beta first.
