Installing CLIMAF with CDAT

The CLIMAF installation is a special case, because we may want to use it with the Python installed for CDAT, but it is not installed using conda and should theoretically work with any available Python, as long as the directory where it is installed is correctly defined in the PYTHONPATH variable

We follow the steps for the installation of a non-standard server

Go to the appropriate installation directory (we choose the directory where we have also installed miniconda3):

LSCE: cd /home/share/unix_files/cdat

ciclad: /data/jypmce/cdat/

git clone https://github.com/senesis/climaf climaf

Add CLIMAF to the PYTHONPATH environment variable

LSCE & tcsh: setenv PYTHONPATH ${PYTHONPATH}:/home/share/unix_files/cdat/climaf

LSCE & bash: export PYTHONPATH=${PYTHONPATH}:/home/share/unix_files/cdat/climaf

ciclad: same as above, using /data/jypmce/cdat/climaf

Test the installation

make sure the Requirements are available:

LSCE: module load netcdf/4 nco cdo ncl ncview

ciclad: module load netcdf4 nco cdo ncl/6.3.0

optional: start an X server

cd climaf/testing
./test_install.sh

Once the tests are OK, add the required module load and environment variables definitions to the .basrc and .cshrc files. Note: maybe these lines should go to the .profile and .login files...(check Bash Startup Files)

LSCE: add to your .cshrc

# Prerequisites for using CLIMAF
module load netcdf/4 nco cdo ncl ncview
# CLIMAF environment variables
setenv CLIMAF /home/share/unix_files/cdat/climaf
setenv PYTHONPATH "${PYTHONPATH}:${CLIMAF}"
#setenv PYTHONPATH $CLIMAF
setenv PATH "${PATH}:${CLIMAF}/bin"
setenv CLIMAF_CACHE "/home/scratch01/${USER}/climaf_cache"
setenv TMPDIR $CLIMAF_CACHE
setenv CLIMAF_LOG_DIR $CLIMAF_CACHE
#conda activate cdatm-nightly_py2

ciclad: add to your .bashrc

# Prerequisites for using CLIMAF when not using the
# default 'module load climaf'
module load netcdf4 nco cdo ncl/6.3.0
# CLIMAF environment variables
export CLIMAF=/data/jypmce/cdat/climaf
#export PYTHONPATH=$PYTHONPATH:$CLIMAF
export PYTHONPATH=$CLIMAF
export PATH=$PATH:$CLIMAF/bin
export CLIMAF_CACHE=/data/jypmce/climaf_cache
export TMPDIR=$CLIMAF_CACHE
export CLIMAF_LOG_DIR=$CLIMAF_CACHE
#conda activate cdatm-nightly_py2

Open a new shell and run the tests again. If there is an error that was not there, check what you have added to the shell init files

We are now ready to start using CLIMAF on ciclad!
