I get the impression that the app either doesn't want to receive 'Intel' as platform name, but 'Beignet', or that it gets 'Beignet' from BOINC and 'Intel' from the OS.

I cannot help with your problem but I too want to get opencl working in Ubuntu 18.04 with my Intel CPU. This Haswell has "HD Graphics 4600" which should be capable of opencl.

I am currently running 5 RX-560 and 1 RX-570 on a BT85 motherboard and had enough trouble getting the AMD driver to work and am concerned that if I try to get the Intel version of opencl to work I may end up with a broken system with only the CPU crunching.

I am going to follow this thread, maybe someone with more knowledge of Linux drivers can help. Actually just being told that both can work together in version xx with drives x and y would be helpfull
