Quick question about timing in OpenMPI. I see that with qstat -a I can show the wall time, and with qstat I can see the CPU time. Is it possible to have these two values written to the output file when the job is done so I can check the performance of my code?

Why don't you use `MPI_Wtime` for measuring elapsed time? – xeroqu Apr 21 '14 at 22:59

@xeroqu I think he also wants the user and kernel times? – niklasfi Apr 22 '14 at 16:26

@niklasfi Yeah that's exactly what I want – Dan Apr 22 '14 at 17:47

@niklasfi I see, alright then. – xeroqu Apr 23 '14 at 17:22
