Since PPR12M offers OpenCL, I tried it and it works on my Intel GPU. It starts off with:

Detected 768 multiprocessors (3840 SPUs) on device 0.


...but is it possible to maybe not use all 768? Is there a switch I can use to reduce how much GPU it uses? Thanks!

I know this thread is 2 years old, but do you recall how you got Intel GPU sieving to work? Thanks :)
