Set up environment

Add this in your ~/.bashrc then source the file

module purge
module load intel/2021.4.0
module load intel-mkl/2020.4.304
module load openmpi/4.0.7
module load hdf5/1.10.7-mpi
module load netcdf-fortran/4.5.3-mpi
module load netcdf-c/4.7.4-mpi
declare -x WHERE_MPI=/net/nfs/tools/u20/22.3/PrgEnv/intel/linux-ubuntu20.04-zen2/openmpi/4.0.7-intel-2021.4.0-43fdcnab3ydwu7ycrplnzlp6xieusuz7/bin/
declare -x NETCDF=/scratchu/spiga/les_mars_project_spirit/netcdf_hacks/SPIRIT
declare -x NCDFLIB=$NETCDF/lib
declare -x NCDFINC=$NETCDF/include

Do not forget to declare the local directory in PATH by adding this to your ~/.bashrc

declare -x PATH=./:$PATH

It is necessary to unlimit the stacksize to avoit unwanted segmentation faults by adding this to your ~/.bashrc

ulimit -s unlimited

In the end, source the .bashrc file!

Set up the installer

Go to your 'data' directory (cd /homedata/_MY_LOGIN_ or cd /data/_MY_LOGIN_) and download the installer with the following command

svn co https://svn.lmd.jussieu.fr/Planeto/trunk/MESOSCALE/LMD_MM_MARS/SIMU

Make sure the installer can be executed

chmod 755 SIMU/meso_install.sh

Make a link (e.g. where you are, in the parent directory of /data) to the main script in this SIMU directory

ln -sf SIMU/meso_install.sh .

Run the installer with a simple display of possible options

./meso_install.sh -h

Install the code

Update to the latest version of installer

cd SIMU
svn update
chmod 755 meso_install.sh
cd ..

Run the installer by providing a name for your specific directory

./meso_install.sh -n DESCRIBE_YOUR_RESEARCH_PROJECT

Special case: In case you do not have a gitlab account, ask for an archive (tar.gz) of the code. Let us assume the name is git-trunk-mesoscale-compile-run-spirit.tar.gz and the file is in the current directory (for instance in /homedata/_MY_LOGIN_) then run the installer with the following command

./meso_install.sh -n DESCRIBE_YOUR_RESEARCH_PROJECT -a git-trunk-mesoscale-compile-run-spirit

Weird! fcm is not working interactively. It only works if being declared in the environment file by adding

declare -x PATH=/homedata/_MY_LOGIN_/DESCRIBE_YOUR_RESEARCH_PROJECT/code/LMDZ.COMMON/FCM_V1.2/bin/:$PATH

then recompile the GCM compiling (which had failed previously) by doing

cd /homedata/_MY_LOGIN_/DESCRIBE_YOUR_RESEARCH_PROJECT/
./compile_gcm.sh

and recreate start files from a sample start_archive.nc by doing

./mini_startbase.sh

Run the full workflow GCM + initialization + mesoscale model

Have a look in the script named launch just for info or to change the number of processors or the step at which you start. Send the launch job to the cluster by typing

sbatch launch

You can check the status of the run by typing

squeueme

A more detailed run

The best is probably to use a more complete startbase than the minimal one that was created. For instance, to get a more complete startbase, link 'data_gcm' to point towards '/data/spiga/2021_STARTBASES_rev2460/MY35'

To use the tyler cap setting in namelist.wps, download the tylerall archive here 'https://web.lmd.jussieu.fr/~aslmd/mesoscale_model/data_static/' and extract the content in the folder named data_static
