I've just setup Arch on my laptop and want to get boinc running and the seti gpu tasks that it used to be able to run under windows. However I can't get boinc to recognise the Intel GPU. I've tried installing both the intel-opencl and beignet packages for opencl drivers and I only get the CPU detected as a opencl device, boinc reports "No usable GPUs". But running the clinfo program shows the opencl devices for each driver package. Can anyone point me in the right direction or where to look for the problem? Thanks

I wouldn't worry my limited experience as is others is that you will get more work done with the CPU wo using the I GPU.

Is the mesa package installed? You may need lib32-mesa as well.

I am running Debian. When I set up mine I had to get beignet 1.3.0 (beignet-opencl-icd) from Jessie backports to support the HD Graphics 530. I also needed to get boinc-client-opencl from there. You don't need mesa.

Given you're running Arch I am not sure how up to date their repos are.

As mentioned above running the iGPU will slow down the rest of the CPU tasks so its usually not worth the effort.

I my case (Linux Mint KDE 18.1) the integrated graphics (BroadWell U-Processor GT1) of the processor (Pentium 3825U) worked after installing beignet package! Thanks!

Also , i think the impact of the gpu crunching in the total performance was not that much (of the total ~13000 sec of task running it needed about ~500 sec of CPU time, if am reading right the task details)
