Help with GPU configuration??

hi himanshu,

yes, it would be cleaner, indeed. Maybe we could also have a fixed post on this GL/CL interop matter, at least on what concerns the system setup. There's too many posts out there, which makes us a little lost.

Well, my system is AMD CPU (Phenom II X4 965), AMD/ATI GPU (Radeon HD 5870), NVIDIA GPU (Geforce GTX 460/1GB), Win7 Pro x64 and most recent drivers/SDKs. I've been successful on using these GPUs individually for GL/CL iterop without switching hardware and reboots. However, I'm not successful on using both GPU at the same time on CL/GL and i'm not successful on using CPU CL + NVIDIA GPU on GL/CL iterop neither (only on pure CL context). I'll write a more detailed post when I'll have a bit more of time (probably by the moon light).

Are you trying to do CL\GL interop taking AMD GPU and NVIDIA GPU together. How do you fit them inside a single context?

 Surely a better explanation of your experiments would be better.
