Hi,

I am looking into running a program on one of the cores which is isolated
(logically offline )
from the rest of the cores. I have come to that the command
echo 0 > /sys/device/system/cpu/<core num>/online

will make a core logically offline,
What I need to do now is to run a program on this offline core. Please
suggest on how to proceed.

Thanks!
Vaibhav Jain

Hi Vaibhav,

I think it's impossible to run out a process on unplugged CPU. May be
AMP[1] is what you need, but it's a bit different approach.
