DaVinci Resolve Dual-GPU config

[Tomasz Huczek]

Hey guys,

Anyone has an experience with CUDA/OpenCL on dual-GPU configs with DaVinci Resolve?

I am working on a CUDA/OpenCL plugin that works OK as long as it's 1 GPU. On dual-GPU crashes Resolve. The only think that makes it work is the "use display GPU for compute" option - which again brings it back to single GPU.

Is it some GPU context switching thing?

Should I select the GPU in my plugin somehow? I suspect that I'm trying to use the resources of the UI GPU instead of the processing GPU...

Any tips?

Thanks,

Tom

This is the current behavior expected from Resolve -  actually I think only Natron has a form of multi-GPU suppprt under OFX OGL suite.
If your plugin does not have dependency on OpenGL at all,  you might want to check the SDK Resolve puts out as part of installing since latest version. It will not work in other hosts (you should have code to bail out of plugin if the host is not Resolve latest version of post IBC last fall).

There is currently a working commitee to add multi-GPU support (OCL and Cuda) in the next API rev, but don't expect that before later this year + time for new host to ingest new API rev.
