LOL. Give us a break, JD - last time you set out on a quest like this, we ended up with a 30% performance improvement from the AK-V8 ;))) Looking at this article on tomshardware, performance improvement from using CUDA in the bits of the code that can use "parallelisation" could be up to twenty times!!... Now that could be good! Any reason for going the OpenGL route rather than directly CUDA? Cross-platform compatibility? Or performance? Or both? Or easier programming? Good luck and good speed!

Regards, Martin My $10 GEForce 6200 doesn't do CUDA... ATI Radeon support w/minimal effort... Past OpenGL programming experience... Desire to learn GLSL and Seti provides interesting challenge... Cheers, JDWhale P.S. If someone wants to donate NVidia GTX280, I'd be happy to give CUDA a go ;-) ID: 792707 ·

And an OpenGL solution would give the widest cross-platform compatibility. Beware the limitations on PCI and AGP based video cards as opposed to PCI-E systems. What doesn't give good timings on AGP may well be fine on a PCI-E system...
