I have noticed that when I also install Intel driver for OpenCL there are errors because there is no underlying hardware. CPU based OpenCL driver is nice to test some stuff. It still needs some work but I can see that ATI/AMD really left nVidia far behind in the Open-Source world. I have just ordered ATI/AMD RADEON RX 580 :-) AMD ROX! =) NVIDIA SUX! =) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
