you can use `sar` utility for this. – Siddharth sharma Jan 08 '16 at 07:31

@Siddharthsharma, I think **`sar`** reports for the whole system, not for individual processes -- Perhaps I misunderstood the question because of "a running process**es**". – Jdamian Jan 08 '16 at 08:10

I gues you could iterate through /proc filesystem analysing files uid and stat*. Then the uid needs to be mapped to /etc/passwd to get real user names. In my opinion a perl script would be more convenient for this need.
