Hi Emanuele,
I wish I could offer some hope that top could soon provide a cpuset limited
view. Unfortunately, our current library offers only a system-wide perspective.
Redesigning that library is on the drawing board. Perhaps that redesign could
also offer a choice of "context" (cpuset, control group, numa node, etc.) and
thereby achieve your goal.
In the meantime, the 3.3.8 version of top offers an "Other filter" feature.
That could be used to limit process display to only those in a given cpuset
without too much difficulty.
Anyway, thank you for your request. I've added it to my wish list.
Regards,
Jim
