Multiple WU's

[daveandton]

Just noticed that I've got 3 WU's running at once. It says 1 is using the GPU and the other 2 just the CPU. Only just happened. Any ideas as it's only ever run 1 at a time in the past

Have you tried stopping BOINC completely and restarting it??

[daveandton]

Yes indeed. The 3 continue running  :cry2:

What project are we talking here?

I haven't seen that behaviour in GPU grid. Do you have a cc_config file or similar set that might be confusing it? Have you tried suspending all GPU work units except the one you want to run?

Ahhhh whoops..

should have read the category  :blush1:

Have you recently updated CUDA drivers?

The only thing I can think of is that GPU Grid recently posted that you need minimum 180 version drivers to run the new WUs... so if you're still on something like 178 that could cause problems..

I don't have an answer and haven't seen that behaviour myself but it would seem this is a BOINC problem, rather than a CUDA driver.  Unless the CUDA driver is telling BOINC that it has 3 GPUs (check the logs)

[daveandton]

Completely mystified. I can stop them one at a time, no probs, got the 180.44 driver  Boinc 6.4.5 none of which have been changed. It shows only the 1 CUDA device but runs the other 2 only using CPU. Got no idea what's happened

Upgrade Boinc to 6.6.28 and see how that goes (Provided you are using windoze)

GPUGrid does use the cpu, but that should be very lightly and restricted to the .15 of A cpu or whatever CPUs are allowed with the CUDA

Have you posted about it on the project forums? I have had great feedback and help when I have posted problems there.

Just going to post on the forum now thanks and if I find out anything interesting I'll let everybody know
