How to force OpenCL (SDK)?

Hello there,

I am developing a plug-in using AE SDK. And would like to use the GPU so I took the sample SDK\_Invert\_ProcAmp as a starting point.

In this sample there are 3 GPU implementations: CUDA, OpenCL and Metal. One more thing to mention is that I have an Nvidia GPU in my PC. Now what I want to do is force the selection to be OpenCL but instead I get the CUDA selection forced.

More specifically, in the method GPUDeviceSetup in the main cpp file (SDK\_Invert\_ProcAmp.cpp), line 270:

if (extraP->input->what\_gpu == PF\_GPU\_Framework\_CUDA) {
...

This field extraP->input->what\_gpu always has the CUDA option and it comes as input, which is invoked directly from the main switch case. You might suggest simply to neglect this value, delete code related to CUDA and Metal and just go on. Unfortunately this will not work, because there is a whole AE GPU utility that depends on this selection and is needed to be used in many parts of the plug-in.

So how does one force the plug-in to use OpenCL, even if there is an Nvidia card available?

Any tips are highly appreciated.
Thanks!
