I’m trying to measure the time spent for the UM model I’m running in ARCHER2. I have by now information from three different sources: file
log.status and running
sacct on ARCHER2.
log.status and the output from
sacct are consistent between them and to my instintive reality: around two minutes.
bo026.fort6.pe.stdout has the following information:
PE 0 Elapsed CPU Time: 94.004 seconds
PE 0 Elapsed Wallclock Time: 111.087 seconds
Total Elapsed CPU Time: 26666.898 seconds
Maximum Elapsed Wallclock Time: 111.087 seconds
The PE 0 Elapsed Wallclock Time seems roughly what I’m looking for. I’m not sure what the extra information means and if that’s important or not.
Finally, after this information, the file
bo026.fort6.pe.stdout has something that resembles the time each routine has spent. In my case, there are 48 routines, but when I add them up, the result is three times PE 0 Elapsed Wallclock Time which, in my mind, should represent the total time.
What am I missing and what’s the best (closer to real-time) way to measure this information?
Kind regards, Luciana.
