Message 14103 - Posted: 26 Nov 2007, 0:06:08 UTC

This afternoon all of a sudden my dual hyperthreaded Xeon processor machine started working at about 42% of each CPU instead of 100% (when nothing else is going on). I tried turning off the BOINC client and restarting it. That did not help. I rebooted the Red Hat Enterprise Linux 5 machine and that did not help (though it booted a new kernel). I stopped BOINC again and reinstalled it. That did no good either. I started to fear machine errors.

I finally noticed on the Seti@home preferences page that it said to keep the processors to about 50% utilization. I increased that to 99% and things went back to normal. I wish I knew you were going to do that today.

Seti is Boinc's testbed so any changes are tried out there first. That said, all they did was make minor changes to the layout. This should not have made any changes to your settings. Mine were not effected in any way.

Something that happened to me once was that I had set the setting to 50% just to test it, but I had an old client where CPU throttling wasn't supported yet. I forgot about it. When I upgraded, the CPU usage was jumping from 100 to 0 and back, intermittently... I thought it was a bug... but it was the setting that *I* had changed long ago :)

That adds to the confusion. I would never have set things to 50%. I did change the % load of most applications from 13% to 12% and raised one from 26% to 31%, but I did not even know I had CPU throttling where I could specify a percentage of cpu load taken by the BOINC client.

Another problem marked "unsolved" in the files of detective ....
