18.4.2. Coupling tools philosophy and workflow

The idea of the coupling tools is to facilitate the management of coupled configurations, the run, and displacement of I/O.

First step is to create a configuration with the usual create_config.bash script, by specifying wich models you want to use in the models options.

From there a configuration architecture will be built:

             - SCRIPTS_TOOLBOX
             - PREPRO
             - OASIS_IN
             - CROCO_IN
             - WW3_IN
             - WRF_IN
             - XIOS_IN
             - OASIS_FILES
             - CROCO_FILES
             - WW3_FILES
             - WRF_FILES
             - DATA

The user will provide:

  • the environment settings, and paths within the myenv_mypath.sh script

  • the settings for the experiment (which models, time stepping, input files…) in mynamelist.sh

  • the settings for the job (dates notably) in myjob.sh

Then the user launch the job with ./submitjob.sh.

The coupling toolbox manage:

  • CROCO compilation if requested

  • Copying the model executables to your configuration directory

  • Getting models input files

  • Preparing OASIS restart files

  • Editing namelists, that is replacing automatically all the fields into brackets <...> in the different namelist files (for all models and for OASIS)

  • Launching the run

  • Putting output files in a dedicated output directory

  • Putting restart files for a future run in a dedicated restart directory

  • Eventually launching the next job if requested
