Bug #2974
position-restraints regressiontest fails on intel GPU with OpenCL
Description
Tested on i7-8550U + UHD 620 and i7-8559U + Iris Plus 655. Only reproduces without DD and nonbonded offloaded. The forces seem to be just slightly off.
Attached log and checkforce output.
History

Target tentative, unless we have a quick solution bump to next release.
#2 Updated by Mark Abraham 6 months ago
- Target version changed from 2019.3 to 2019.4
I reproduced on my i7-7500U (neo), but without leads, we'll have to bump this for now

Sure, I agree.

Still failing on both 2019 and master. I have no leads, but it can't be a PME issue as this test does not use PME.
#5 Updated by Mark Abraham 3 months ago
The logic about whether and how position restraints get run is pretty convoluted, so I could well believe that force contributions could be missed

no fix in sight, bumped
#8 Updated by Szilárd Páll 9 days ago
Something changed that seems to make the same test on the same hardware on the current 2020 branch whereas on 2019 it still fails.

should I move this to 2020 instead? to indicate it is fixed there?
#10 Updated by Szilárd Páll 9 days ago
It would be good to know what has changed, even if we don't fix it in 2019, so I'd prefer to not close this yet.
