I'm running Rosetta and Seti@Home on Boinc 5.10.8. I've explicitly set Boinc to run at a maximum of 90% CPU *only* when the machine is idle (meaning no activity for at least 3 minutes), but Boinc runs at varying CPU usuage levels up to %82 when the computer is in use. I've tried various settings of CPU usuage, but I can't get Boinc to STOP running when I'm using the machine.

Am I missing something altogether?

Thanks,

~ Eric.

Linux seems to have some issues in preempting the Rosetta thread. This thread is discussing the Linux issues in more detail.

It appears the CPU throttling is "approximate". Upgrading to BOINC 5.10.21 (or downgrading to 5.8.16) may help, but no promises there. (They just released 5.10.21 this week.)

Also, the idle detection only works with the /dev/console keyboard input (and X server), so moving the mouse around will not cause it to stop crunching. Pressing any keyboard button will. This behavior appears to vary by distro.
