Hi Szilαrd Thanks for your reply. I have run the deviceQuery utility and what I got back is
/deviceQuery Starting... CUDA Device Query (Runtime API) version (CUDART static linking) cudaGetDeviceCount returned 38 -> no CUDA-capable device is detected Should I understand from this that the CUDA driver was not installed from the MAC OS X CUDA 5.0 Production Release?
