This seems to be the limitation of ATI 4*** cards (barriers are not supported for high workgroup sizes). Unfortunately, I do not have any ATI cards in my disposal and therefore I did not test pyfft on ATI at all. Does pyfft give correct results despite the warning? Could you please run test scripts (located in test/ folder in the distribution, you can just run test_all.py) on this ATI card? > There is another issue, I'm trying to calculate using an ATI4870, but the > cl_array.sum is not working. It works on my CPU, but not on the GPU.

You should probably move this to a separate thread, as this has nothing to do with pyfft --- looks like PyOpenCL issue.
