9) Message boards : Number crunching : Can't get GPU tasks (Message 116266)
Posted 1119 days ago by Profile Adrian SchoriProject donor
I seem to be unable to get any GPU tasks. According to the log, NVIDIA tasks are frequently requested but always turned down.

I am running Mac High Sierra with an NVIDEA GPU. How do I figure out where my problem is?

Thanks,
Jim


I have the same problem since a while and still no solution for it: http://www.primegrid.com/forum_thread.php?id=7732

I get GPU tasks from einstein@home and milkyway@home without any problems, but no PrimeGrid tasks.

Adrian Schori,
In your primegrid preferences there are few checkboxes at the top (Use ATI/AMD GPU, Use NVIDIA GPU), is the according one enabled?


My GPU is NVIDIA GeForce GTX 675MX and I enabled the "Use NVIDIA GPU" checkbox. I did not change my preferences since a long time. It worked for years without problems. I updated to the newest BOINC manager Version 7.8.6, but I still can't get any work for GPU from PrimeGrid. GPU tasks from einstein@home work fine.

I don't know, but maybe it has to do with the annoying problem, that macOS High Sierra 10.13 is incompatible with the GPU CUDA driver as discussed her: https://devtalk.nvidia.com/default/topic/1025945/cuda-setup-and-installation/mac-cuda-driver-fully-compatible-with-macos-high-sierra-10-13-error-quot-update-required-quot-solved-/1
