Download:
Information (if needed) about how to get the sources.
./download.shCompile:
See
./compile.shRun and validate the simulations:
Five configurations (see below) should be performed for 20000 steps each
1560 tasks ; jpni=52, jpnj=30
1920 tasks ; jpni=40, jpnj=48
2160 tasks ; jpni=45, jpnj=48
2640 tasks ; jpni=40, jpnj=66
3960 tasks ; jpni=60, jpnj=66
- before launching the runs check the file:
grep nn_itend $HOME/release-4.0/tests/BENCH/EXP00/namelist_cfg_orca1_like
nn_itend = 20000 ! last time stepnn_itend value should be set at 20000 (default=1000)
- Change the flag to get timing information
grep timing $HOME/release-4.0/tests/BENCH/EXP00/namelist_cfg_orca1_like
ln_timing = .true. ! timing by routine write out in timing.output fileReporting results :
Please commit these files for each configuration
