GPU affinity mask so OpenGL commands go to a specific device

Hi,

My Linux system has two GPUs: a Tesla and a Quadro. I want to do the computation on the Tesla and then send the results to the Quadro to do the OpenGL rendering.

Do I need to specify that OpenGL commands are only sent to the Quadro device, and not the Tesla?

As far as I know, the WGL_NV_gpu_affinity extension does this on Windows system. Is there some sort of equivalent on Linux?

cheers
