Thread: measuring CPU usage

Hi all,

Is there a way to measure CPU usage from your application's perspective? For example, I have an application that uses MPI and OpenMP that runs on a Xeon Phi. I just want to, using relatively standard Linux tools and available tools, see how much CPU usage each of the processes are using. I am figuring out how different settings will affect CPU utilizations/performance. PAPI seems a bit complicated right now given the time constraint.

Is this the right place to ask? Should I ask in a Linux forum?

Thanks
