We could discuss that here, but the discussion that will matter will be among the F@h software developers and researchers. They will need to see enough potential additional systems that can do GPU folding under macOS to justify putting the time and effort into creating the necessary GPU folding cores.sub_pixel wrote:Given that MacOS now has OpenCL and CUDA support built-in, and given that there are many MacBook Pro laptops with discreet GPU hardware capable of out-performing the CPUs in those laptops, I'd like to propose that we re-open this discussion?
You mention "many MacBook Pro laptops", but only the high end 15" MBP's have discrete GPU's. Among these only the most recent ones are powerful enough. The same applies to iMac's. The iMac Pro is an exception, but they are not a volume system from Apple.
Yes, the OS has OpenCL support, in fact it has had it for many years. But Apple introduced a bug a number years ago around the time of 10.7 the was not fixed until recently. That bug kept early test versions of the GPU cores from functioning properly.
As for CUDA support, is that actually included now? The last I checked CUDA support had to be downloaded as an optional package from nVidia.
