Hy all, Maybe I'm wrong but I think I have found a bug in the OpenCL SDK 2012 with the clGetDeviceIDs function. When I call it with these parameters: clGetDeviceIDs(intelPlatformId, CL_DEVICE_TYPE_GPU, 0, NULL, &nbDevice); it must returnsCL_DEVICE_NOT_FOUND but it returns CL_SUCCESS and nbDevice is set to 0. I don't try with other DEVICE_TYPE but I can if needed.

Hi,

Thanks for reporting the issue. Yes, it looks like a bug (I verified I am seeing the same behavior as you). When no devices are found matching the device_id, clGetDeviceIDs must return CL_DEVICE_NOT_FOUND. I will file an issue and let you know when a fix is available.

Thanks,
Raghu
