profiling per application

[Piyush S. <sh...@cs...>]

Hi,

I am relatively new to oprofile. My apologies if it is a silly question.

I am trying to gather system CPU utilization on a per-application basis. 
If the application forks off multiple processes, does the profiling data 
get clubbed to the main program (the parent process for all these 
processes)? Similarly I was wondering what happens if a process forks and 
execs another program?

Can I use oprofile to gather CPU utilization data for multiple such 
applications on the same node on a per-application basis?

Thanks,
Piyush
