Hi,
I was wondering if somebody can help in doing the following:I want to get the power
consumption of each thread running. I am doing an experiment. I built a program that
executes on several threads and I need to know the power consumed by each thread or by
each core of the eight CPU cores I have. I do know the process ID of the processes that
start but I don't know how to get their power consumption using powertop.
I appreciate somebody's help.
Regards,
Christopher Mansour

This is pretty much impossible to do as there's no way to actually
physically measure the power draw of a thread, and threads on a core
aren't receiving power separately and are often grouped when it comes
to power. Because of the complexity, there's just no solution to
getting per-thread power simply from a normal system.
