Hi,
I'm a research student, working on self-organizing
grids.
I wanted to ask how can I find the cpu usage of a
process, as opposed to runtime, with cpu usage I mean
actually how many time slices were awarded to a
specific process, like the runtime of job may be 4 s,
but this also includes time it was suspended by some
interrupt, or had to wait for the scheduler etc..
What is the easiest way to do that? is their any
userlevel tool for it?
Thanks in advance
Irfan Habib

getrusage(2) or if it's not a child then grovel through /proc (i think
there is an argument for a better interface)
thank you very much for every one who replied.
It really helped me big times :)
