Description:

Technical information:

• Scientific domain :climate
• Language : Fortran
• Parallelism : MPI +
• GPU acceleration : No
• Scalability : high
• Vectorization: moderate

Compilation and simulation:

Download:

Information (if needed) about how to get the sources.

./download.sh

Compile:

See

./compile.sh

Run 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

1. 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 step

nn_itend value should be set at 20000 (default=1000) 2. 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 file

Reporting results : Please commit these files for each configuration
