Hardware: laptop with Intel Core i5 6200U CPU Software: Fedora 24 64 + all updates + kernel 4.8.6 Whenever I run any OpenCL applications my entire desktop almost completely freezes: the mouse cursor barely moves, I cannot type anything, there's a huge delay whenever I try to interact with anything. In short the desktop becomes unusable. This happens for instance when running: $ clpeak --all-tests for most tests CPU usage remains negligible. I have verified the issue with both Intel proprietary OpenCL drivers ( Intel intel-opencl-r3.0 (SRB3) Linux driver package ) and Beignet open source drivers.
Xorg.0.log?

I'm curious why you changed the component to "Driver/modesetting". It looks like no one will be looking at this bug any time soon.
I think this is expected with clpeak.
I said in the original post: > I have verified the issue with both Intel proprietary OpenCL drivers ( Intel intel-opencl-r3.0 (SRB3) Linux driver package ) and Beignet open source drivers. I'm reverting the title. (In reply to Vedran Miletić from comment #4) > I think this is expected with clpeak. I thought GPUs are exceedingly multithreaded/parallelized/etc. which means they have enough power to multitask efficiently.
