I think you can test this theory by running only 44*64 workitems. so it should run allocate only 50MB of private memory.

Hi Acekiller, How quarter wave-fronts are actually scheduled is not known, but what is true is that one wave-front (of 64 threads) will always execute in one lock-step, as if they have an implicit...

I solved the first issue myself: Due to the weak consistency memory model, accesses to counter caused an unexpected behavior.It was fixed by using a mem_fence: counter = (counter + 1) % 10...
