Change in run-time speed #569

Open vittofra opened 3 weeks ago

vittofra commented 3 weeks ago

We (@aydogduali and I) have been performing several runs of neXtSIM-DG in the last few months on different machines. Lately I have been noticing that the run time became longer compared to the April version one. Find the details in the following:

  1. Previous version (fast one): Schermata del 2024-06-05 14-10-53

    Time real 0m2,839s user 0m2,365s sys 0m0,473s

    This is what the configuration file looks like: Schermata del 2024-06-06 09-52-59

  2. Most recent version of the develop branch (slower): Schermata del 2024-06-05 14-11-27

    Time: real 4m12,750s user 4m12,678s sys 0m0,046s

    Same config file.

I noticed that in the second version I am reporting here the message "Spherical coordinates are not yet implemented. Reverting to Cartesian." does not pop-up anymore (so I guess in this version it has already been addressed).

Can you explain somehow this change in speed? @timspainNERSC @einola

Thanks!
