Topic 226764

I have set <use_all_gpus> to 1 and had both gpus running until recently and once in a while the second gpu will kick in. I don't see anything in the log files that would prevent it from running. I turned on coproc_debug  in Event Log options and I get the following messages and BOINC does recognize to assign a workunit to the gpu instance but thats it... Is this a BOINC issue or Einstein@home one? Here are the messages. Instance 0 seems to have addition messages but Instance 0. Just repeats on Assigning a WU to the instance.

1/12/2022 10:49:15 AM | Einstein@Home | [coproc] NVIDIA instance 0: confirming 1.000000 instance for LATeah3011L06_692.0_0_0.0_19627524_0
1/12/2022 10:49:15 AM | Einstein@Home | [coproc] Assigning NVIDIA instance 1 to LATeah3011L06_692.0_0_0.0_19648611_1
 

I have tried resetting the project and rebooting the computer

Hmm There is a hint in the

Hmm There is a hint in the cpu_sched_debug, message indicates that that the CPU is committed.. Message is:

1/12/2022 11:08:11 AM | Einstein@Home | [cpu_sched_debug] skipping GPU job LATeah3011L06_692.0_0_0.0_15274656_0; CPU committed

So need to figure out what CPU committed means now. I only let the have BOINC have  only 75% of the CPUs.

First I would suggest that

First I would suggest that you make your computer(s) visible.  Without this, we do not know what system you are running, what GPUs you are using, etc.  You would get more help with the computer(s) visible.

Digging a bit deeper

Digging a bit deeper their  is a discussion about this on boinc forums.

 

GPU tasks skipped after scheduler overcommits CPU cores (berkeley.edu) 

 

But appears there is no real solution to the problem.

We cannot see your named computer "wks-ubuntu-005".  Could you identify the computer in question by it's ID # ?

Does the second GPU start

Does the second GPU start working if you suspend CPU work? What CPU project are you crunching?

Hmm - I was able to get the both GPUs going by deleting all of the non-GPU work units. Will see how long they continue to both work.

If you haven't already, you

If possible, could you copy/paste your  cc_config.xml  and your  app_config.xml  files here so we can see what you're up against?
