Hi Sir,
This id Dhanraj,Im working on a power optimization program and would like
to know how to only check the power consumed by a single application and
how to change its C State in Linux.
I'm using CentOs and powertop ver 2.7.
Thank You..

You can't know the exact power consumption of an application. You can
determine the differential in power of an idle system and an idle system
with one application.

You can't change the C state of one program. C States are something that
affect the entire processor, not something that is per process.

Please share your power optimization code!

Cheers,

Auke
