Hi!
I've missed the message boats a few times so... Could anyone explain the affinity thing again. If I understood it correctly, it's used to lock a process to a certain CPU.
When running say a SETI@Home and some other apps at the same time, and then check top, I see a behaviour for the SETI process where the status goes something like: CPU0->RUN->CPU1->RUN->CPU0.... Does that mean that the process is bouncing back and forth between the CPUs?
Any help and explanations would be very much appreciated.
BTW: I'm running a Dual Celeron on ABIT BP6 machine with FreeBSD 3.3 STABLE.
