ReBuild 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 purge
module load EasyBuild/2023a
module load Perl-bundle-CPAN/5.36.1-GCCcore-12.3.0
MODULEPATH=$MODULEPATH:/gpfs/projects/acad/ecearth/softs/easybuild/modules/all
module load netCDF-Fortran/4.6.1-iompi-2023a
module load imkl/2023.1.0 
module load grib_api/1.24.0-iompi-2023a 
module load CDO/1.9.10-iompi-2023a
module load OpenJPEG/2.5.0-GCCcore-12.3.0

Then, go to your EC-Earth repository (3.3.3.2)

cd ~/models/ecearth_3.3.3.2

ReCompile

  • Clean and recompile oasis:
cd ~/models/ecearth_3.3.3.2/sources/oasis3-mct/util/make_dir
make BUILD_ARCH=ecconf -f TopMakefileOasis3 clean
make BUILD_ARCH=ecconf -f TopMakefileOasis3 realclean
make BUILD_ARCH=ecconf -f TopMakefileOasis3
  • Clean and recompile IFS:
cd ~/models/ecearth_3.3.3.2/sources/ifs-36r4
make BUILD_ARCH=ecconf clean
make BUILD_ARCH=ecconf realclean
./makeifs -j 4
  • Recompile xios from scratch:

!!! change to do in extern/blitz/blitz/funcs.h +575 replace: return BZ_STD_SCOPE(isnan)(a); with: return isnan(a);

cd ~/models/ecearth_3.3.3.2/sources/xios-2.5
./make_xios --full --prod --arch ecconf --use_oasis oasis3_mct --netcdf_lib netcdf4_par -j 4
  • Clean and recompile NEMO:
cd ~/models/ecearth_3.3.3.2/sources/nemo-3.6/CONFIG
rm -rf ~/models/ecearth_3.3.3.2/sources/nemo-3.6/CONFIG/ORCA1L75_LIM3/BLD/
./makenemo -n ORCA1L75_LIM3 -m ecconf -j4
  • Clean and recompile runoff-mapper:
cd ~/models/ecearth_3.3.3.2/sources/runoff-mapper/src
make clean
rm -f ~/models/ecearth_3.3.3.2/sources/runoff-mapper/bin/runoff-mapper.exe
make

Run

Check the job script EC00.sh and compare the changes with your script:

New EC00.sh

cd
wget https://gogs.elic.ucl.ac.be/pbarriat/ecearth3/raw/master/runtime/classic/EC00.sh
cd ~/models/ecearth_3.3.3.2/runtime/classic
vimdiff my_script.sh ~/EC00.sh

Data

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