reporting cpu times

March 25, 2004, 10:09

I have been asked to report the CPU time taken by my program. For that I have compiled my program and got the times as given below (I have used "time nohup a.out < in > out &") real 60.3 user 55.3 sys 4.9

Kindly let me know the CPU time taken for running my program, I mean which value shall I report in any journal paper?

Thanking you

For benchmarks, I've always cared most about wall time (ie the time shown by a clock on the wall) for a machine that was not loaded with any other work. That would correspond most closely with "real".

If you are using linux use the "top" command to find the accurate time.
