Timing information for the EC-Earth and CESM1 models run on NSC's triolith system. All timing results are calculated from 2 month simulations (Jan-Feb), extrapolated to a full simulated year based on the number of days (365 / 59). So, the throughput measured as sim_years / day values is calculated as:
- sim_years / day = (24 * 60)/(2 month sim time * (365/59))
and the efficiency (pe_hours / sim_year) is calculated as:
- ps_hours / sim_year = (24 * total number of cores)/(sim_years/day)
- EC-Earth version 3
