printf on GPU is not supported on HD4000. One way to debug is to write intermediate values to a debug buffer and read it back on the host. You can them compare the result with that you got on the CPU. Sorry there is no easy way currently. Thanks, Raghu

what about he current status of printf support on HD4000, as in OpenCL 1.2 printf is built in function.

Thanks
