I currently need the ability the disable a certain number of compute units inside a GPU, is there any way of doing this with openCL 2.0? I was going to do it via clCreateSubDevices and essentially feed my program a sub device certain number of CU's via that call, and then the "other" device would just sit idle. Doing some research it seems that this API is not supported by AMD this still the case for Polaris GPUs as well? If so, any other way I could force certain number of CUs to not work?
