Initialization (section init)

  • For MARS initialization, for rank_0 date_startshift=-2 and for rank_1 date_startshift=0, in order to give enough time for tide to propagate correctly in rank 0. This means that rank 0 starts 2 days before rank 0, so you have to make meteo start 2 days before start date. Check in section meteo:

#startshift = -1.0
startshift = -2.0

  • If you only want to run MARS (no post-processing), change treatments in section treatments:

#list = ['meteo', 'obc', 'river', 'rank_0', 'rank_1', 'format_oco','demerliac','mirror_copy','finalize']
list = ['meteo', 'obc', 'river', 'rank_0', 'rank_1']

  • If you want to modify the number of processors, change nmpi in section rank_0 and rank_1 (in this case, do not forget to move mpi.txt if it exists !)

Note

In MARS run directory (MARS/RUN_MARS/MANGAE2500/MANGAE2500-r1630/), paraspec.txt.init is systematically copied at the beginning of the run in paraspec.txt. To change paracom paraspec or output parameters, make it directly in configuration file in subsections [[[paracom]]], [[[paraspec]]] or [[[output]]].

[[[paracom]]]
  #file_meteo = '../../inputs/mangae_meteo.nc'
  file_meteo = 'my_file.nc'
[[[paraspec]]]
  l_out_nc4par='.false.'
[[[output]]]
  time_startout = '00:00:00'
  l_out_ubt = '.false.'
  pasor = 0.25

  • To initialize a MARS run from 01/01/2014 to 03/01/2014:

launch_mangae config_mangae.cfg -s 2014-01-01,00:00 -e 2014-01-03,00:00 --init
  • To follow if the run is OK

    • check if sections are OK in f1-mangae.xml

    • in case of problem, check the log files ./logs/MANGAE2500-r1630/20140101_20140103/*.log

  • Output files:

    • init file: ./inputs/MANGAE-2500-r1630/init/mangae_init.nc

    • MARS results and save files in RDIR ./MARS/RUN_MARS/MANGAE2500/MANGAE2500-r1630/:

      • rank_0/champs_r1630.nc

      • rank_0/save_20140102000000.nc

      • rank_0/save_20140103000000.nc

      • rank_1/champs_r1630.nc

      • rank_1/save_20140102000000.nc

      • rank_1/save_20140103000000.nc

  • Section init allows to create init file for MARS with extract, it is automatically launched with options –init
