BTW, cgroups is (now) what cpusets used to be - you may see the latter still mentioned in some doco. They are (for your purposes) the same.
The kernel documentation (http://www.kernel.org/doc/Documentat...parameters.txt
) says that
"This option can be used to specify one or more CPUs to isolate from the general SMP balancing and scheduling
This option is the preferred way to isolate CPUs."
So, according to that, scheduler/load balancer should not put any process on the isolated CPUs, isn't it?
Other thing is that my daemon runs normally on polling mode (CPU usage 99%), when polling switched off, its CPU usage gets down to some 55%. How can this happen if there is no other process on that CPU's runqueue?.
sorry about the string of questions, appreciate your help syg00
