EC-Earth_patch

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 TECLIM: install, run management, etc.

Install

First, clone the pbarriat/ecearth_patch repository and update your shell startup script to source the 'bashrc' file to add ecearth globals variables to your environment. For instance:

git clone ssh://egit/pbarriat/ecearth_patch.git

Then, checkout the EC-Earth SVN repository. For instance:

svn co https://svn.ec-earth.org/ecearth3/tags/3.2.2 ecearth_3.2.2

YOU MUST HAVE YOUR ~/.ssh/id_rsa.pub FILE BEFORE STARTING TO WORK WITH GIT ON ZENOBE.

Final step, go to the pbarriat/ecearth_patch repository, open & adapt the install.sh script and run it:

cd ecearth_patch
./install.sh

Compile & Run

Compile the model:

1. Go to ~/modeles/ecearth/$release/sources and:

   ./util/ec-conf/ec-conf -p zenobe-intel-intelmpi config-build.xml
   

2. Go to ./oasis3-mct/util/make_dir and:

   make BUILD_ARCH=ecconf -f TopMakefileOasis3
   

3. Go to ./ifs-36r4 and:

   ./makeifs -j 4
   

4. Go to ./xios-2 and:

   ./make_xios --prod --arch ecconf --use_oasis oasis3_mct --netcdf_lib netcdf4_par -j 4
   

5. Go to ./nemo-3.6/CONFIG and:

   ./makenemo -n ORCA1L75_LIM3 -m ecconf -j4
   

6. Go to ./runoff-mapper/src and:

   make
   

For a quick classical run test:

• Go to ~/modeles/ecearth/$release/runtime/classic and:

  ../../sources/util/ec-conf/ec-conf -p zenobe config-run.xml
  

• Submit the script ece-ifs+nemo.sh to the PBS batch system:

  qsub ece-ifs+nemo.sh
