Thank you for your explanations about your experience. Of course I would like to avoid such problem by choosing the correct hardware. Therefor I would use a desktop computer, disable the integrated GPU and just use the PCIe graphics card.
I usually use ArchLinux which always contains the bleeding edge software. I hope to have a easy solution for OpenCL performance via repository. Karsten Am Donnerstag, 4.
