Hi All,

I thought you might have some better hints.

As you know that running processes can be mapped to different CPU cores
(irqbalance or manual). By default process affinity is f or ff etc.
based on the number of available cores.

Is there a way (other than taskset or poking /proc) to see which process
is using which core , I mean through some some Linux tool ? I tried
htop, top, atop, mpstat ... but they tell a summary of total core usage,
but not about that specific process which just consumed 40% of that core.

An alternate way could be to get a process list and force taskset the
interested ones.

Thanks
