Important Notes

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

mv $HOME/.ssh/config $HOME/.ssh/config_old
cat config | sed -e 's/pbarriat/'$USER'/g' > $HOME/.ssh/config

[ ! -f ~/.ssh/id_rsa.pub ] && ssh-keygen -t rsa
ssh-copy-id -i ~/.ssh/id_rsa.pub gwcism.cism.ucl.ac.be

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://regit/pbarriat/ecearth_patch.git

Then, checkout the EC-Earth SVN repository. Three alternatives:

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

svn co https://svn.ec-earth.org/ecearth3/branches/projects/primavera ecearth_primavera

svn co https://svn.ec-earth.org/ecearth3/trunk ecearth

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

cd ecearth_patch
./install.sh

Compile & Run

First, sign out of Zenobe and sign in again. Then, type configure_ecearth.

Compile the model:

Go to ~/modeles/ecearth_$tag/sources and:

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

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

make BUILD_ARCH=ecconf -f TopMakefileOasis3

Go to ./ifs-36r4 and:
```
./makeifs -j 4
```

Go to ./xios-2 and:

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

Go to ./nemo-3.6/CONFIG and:

./makenemo -n ORCA1L75_LIM3 -m ecconf -j4

Go to ./runoff-mapper/src and:
```
make
```

Primavera context:

Go to ./amip-forcing/src and:
```
make
```

Go to ./util/ELPiN and:

mkdir bathymetries
ln -s /SCRATCH/acad/ecearth/DATA/nemo/initial/ORCA1L75/bathy_meter.nc bathymetries/ece_bathy_meter_ORCA1.nc
ln -s /SCRATCH/acad/ecearth/DATA/nemo/initial/ORCA025L75/bathy_meter.nc bathymetries/ece_bathy_meter_ORCA025.nc
sed -i 's#"$min_num"#"${min_num/./,}"#g' ELPiNv2.cmd
sed -i 's/ORCA025/ORCA1/g' src/namelist_mpp
./Configure

For a quick classical run test:

Go to ~/modeles/ecearth_$tag/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
```
