reporting cpu times
 
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.


All times are GMT -4. The time now is 01:20.
