1. Initialisation¶

The model code currently running on Levante is in /work/aa0049/a271098/CTSM and https://github.com/AdrienDams/CTSM/tree/levante.

The current CTSM version is ctsm5.1.dev086-3-gec6bb36a9 and will be updated reguraly.

1.1. Copy the folder /home/a/a271098/.cime into your home directory:

cp -Lr /home/a/a271098/.cime ~

1.1.1 In line (504) of config_batch.xml:

    <directive> --account=aa0049           </directive>

change your account name.

1.1.2 In line (13) of config_machines.xml :

    <PROJECT>aa0049</PROJECT>

change your account name.

1.2. Load these modules

module load git openjdk python3 intel-oneapi-mpi/2021.5.0-intel-2021.5.0 esmf/8.2.0-intel-2021.5.0 gcc slk netcdf-c/4.8.1-openmpi-4.1.2-intel-2021.5.0 netcdf-fortran/4.5.3-openmpi-4.1.2-intel-2021.5.0 intel-oneapi-mkl/2022.0.1-gcc-11.2.0

1.3. Do these additional tags

export CIME_MACHINE=levante
MKLROOT="/sw/spack-levante/intel-oneapi-mkl-2022.0.1-ttdktf/mkl/2022.0.1" 

1.4. Add to your ~/.condarc (or create file)

channels:
  - conda-forge
auto_activate_base: false

2. Create a case¶

The resolutions that have been tested on Levante are: [f19_g17] . The compsets that have been tested on Levante are: [I2000Clm50Sp], [I2000Clm50BgcCrop], [I2000Clm50Fates] .

2.1. Create your case (example here is with the resolution f19_g17 and the compset I2000Clm50Sp )

/work/aa0049/a271098/CTSM/cime/scripts/create_newcase --case I2000CLM50_001 --mach levante --res f19_g17 --compset I2000Clm50Sp --run-unsupported

3. Build the model¶

3.1. Setup your case

./case.setup

3.2. Build your case

./case.build

4. Submit the case¶

./case.submit

Thanks for Heidrun Matthes, Irina Fast, and the DKRZ support team to help me install CTSM on Levante.
