Message 26366 - Posted: 30 Jul 2009, 15:42:54 UTC

Hello

This concerns Boinc on my 24" iMac, 2.8 Ghz. Looking at my Activity Monitor, the two projects currently running are using about 70% of each of the two cpu's. But it also shows that another project (waiting to run) is using 45%. Why is a project waiting to run using the cpu?

Thank you, in advance.

If it is a CPU intensive project's application, it shouldn't.
So exit BOINC and check again whether or not that application is still running. If it is, then stop its process and restart BOINC.

Correct. At the time of the first post, Poem was running on the two processors, and S@Home was the odd wu. No S@H is running on the two processors, and another (waiting to run) S@H is using 50% cpu.

I closed Boinc and the nothing changed in the Activity Monitor, so I Quit Boinc and the two runing wu's closed, but the Waiting To Run wu jumped to 97% cpu. I've restarted Boinc and it's back to three wu's using cpu - 75-75-45%

While you folks ponder, I'll restart the computer and see if that helps...

I restarted the iMac and the mystery wu has disappeared and all is back to normal.

Thanks, again.

All right, then for an explanation: it happens sometimes when BOINC switches applications that it doesn't completely stop one of the running applications. That one will then, independently of BOINC, go about its business. The only way around that is to exit BOINC (quit it) and then manually remove the rogue application, or as you did reboot the system.

There is a good chance that when that task restarts in BOINC, that it will go out with an error.

Thanks Jord - I'll watch the offending wu and see what happens.
