1) Message boards : Number crunching : Is there a way to limit the number of cpus... (Message 48826) Posted 17 May 2011 by elliotts Post: I think my issue is the essentially the same, so I will post it here. Moderator - please move if I posted in the wrong place. I have an i7 processor. When I receive multi-threaded tasks from milkyway, instead of my system all 8 cores at 100%, the processor utilization bounces around between 30-60% for all cores. If I suspend all other processing and let the milkyway task have the entire processor, the task completes in about 8 minutes. If I just let it run, without suspending the other tasks, the milkyway task takes hours to complete; and virtually nothing else is processed. Likely more time is spent swapping out tasks than actually crunching numbers... It would be nice if I could set something to let the milkyway task take over the system when the application switch occurs. Then it could run to completion, after which the other tasks in the queue would run normally. Are there any project setting that control how multi-threaded applications interact with single-threaded apps that would help me? I was told the BOINC client does not have anything in this regard... TIA for any assistance, Tom
