OpenCL and multiple GPU's

Recommended Posts

Any OpenCL experts able to tell me whether OpenCL is 'multiple-GPU' aware? Just wondering if there are any sim performance advantages in enabling OpenCL on multi-GPU systems...

Is there even a way to disable OpenCL on compatible devices?

My understanding is that OpenCL will use GPU, and if not available, will fall back to CPU.  That's the reason its safe to use OpenCL SOP in HDA's.

openCL nodes in houdini does not support multi GPU, it just runs on the first GPU in the system. it has only a fallback option to CPU.

basicly, openCL is runs on everything at some some time cpu and gpu but current houdini does not support it yet,
