Title:
[regression] Wrong EU count for i5-5250U, reducing OpenCL performance
Status in beignet package in Ubuntu:
In Progress
Status in linux package in Ubuntu:
Incomplete
Bug description:
I run a BOINC project which uses opencl_intel on my Kubunut system
On bioinc the tasks ran in 12,000 +/- 200 seconds.
They've been doing that for ~6 months.
I've now updated the system to cosmic, and the task are not taking
19,000 +/- 200s.
I have another system (which is still running Mint18.3 - and hasn't
changed) which also runs these tasks and the timings there have not
changed, so the tasks themselves are still equivalent.
