Hi,

Imagine I have multiples GPU (imagine 2), can I ask to each GPU to draw in 50% of a PBO using OpenGL Interop ?

I think that there is no sample in the SDK 😛

If yes, what is the best way ?

My goal is to share the processing and draw in the same image (shared buffer).

Thanks

OpenGL interoperability work only with one GPU and that GPU must be also used for OpenGL drawing.

it can work with multiple GPUs but in fact it do copy so i recomend using manual copying.

and of course you need buffer per GPU as write to same buffer from multiple queues at the same time is undefined.
