Build EC-EARTH on LUCIA

EC-Earth is a global coupled climate model. It is developed by a consortium of European research institutions. The goal of this project is to adapt this model for our needs in ELIC: install, run management, etc.

User requirements

First, load the required env modules

module load craype-x86-milan
module load PrgEnv-intel/8.3.3
module load Perl/.5.34.1-GCCcore-11.3.0
MODULEPATH=$MODULEPATH:/gpfs/projects/acad/ecearth/softs/easybuild/modules/all
module load netCDF-Fortran/4.6.0-iompi-2022.05
module load imkl/2022.1.0 OpenJPEG/2.5.0-GCCcore-11.3.0 grib_api/1.24.0-iompi-2022.05

Then, clone this EC-Earth fork repository (3.3.3.2)

mkdir -p ~/models
cd ~/models
git clone https://gogs.elic.ucl.ac.be/pbarriat/ecearth3.git ecearth_3.3.3.2

Compile

• Compile oasis:

cd ~/models/ecearth_3.3.3.2/sources/oasis3-mct/util/make_dir
make BUILD_ARCH=ecconf -f TopMakefileOasis3

• Compile IFS:

cd ~/models/ecearth_3.3.3.2/sources/ifs-36r4
./makeifs -j 4

• Compile xios:

cd ~/models/ecearth_3.3.3.2/sources/xios-2.5
./make_xios --prod --arch ecconf --use_oasis oasis3_mct --netcdf_lib netcdf4_par -j 4

• Compile NEMO:

cd ~/models/ecearth_3.3.3.2/sources/nemo-3.6/CONFIG
./makenemo -n ORCA1L75_LIM3 -m ecconf -j4

• Compile runoff-mapper:

cd ~/models/ecearth_3.3.3.2/sources/runoff-mapper/src
make

Run

Check the ecconf.cfg the first job script EC00.sh and submit

cd ~/models/ecearth_3.3.3.2/runtime/classic
sbatch EC00.sh

Data

I prepared all the input files in /gpfs/scratch/acad/ecearth/data/bsc32/ directory.

Very first try
