1. Load required modules and set environment variables
Paste the below lines into your terminal. (Putting these in ~/.bashrc is not recommended.)
module purge
module purge
module load ParallelIO/2.6.2-cpeIntel-23.09
module load METIS/5.1.0-cpeIntel-23.09
export PIO=${EBROOTPARALLELIO}
export NETCDF=${CRAY_NETCDF_HDF5PARALLEL_PREFIX}
export PNETCDF=${CRAY_PARALLEL_NETCDF_PREFIX}
export OPENMP=true
### Common mistake :: insert spaces before or after =2. Download MPAS source code
An example for MPAS 8.0.1 is as shown below.
wget https://github.com/MPAS-Dev/MPAS-Model/archive/refs/tags/v8.0.1.tar.gz
tar xzf v8.0.1.tar.gz
mv MPAS-Model-8.0.1 MPAS
cd MPASFor other version, check https://github.com/MPAS-Dev/MPAS-Model/releases.
3. Compile MPAS
Compile each MPAS core with your desired floating-point precision; for example,
make -j4 intel-nersc CORE=init_atmosphere PRECISION=single AUTOCLEAN=true
make -j4 intel-nersc CORE=atmosphere PRECISION=single AUTOCLEAN=true
... User still has to use make clean CORE=XXX before recompiling each core.
Additional notes:
CORE=ocean only supports double precision.
CORE=seaice only supports double precision and only serial build (-j1) works.
Users may have to add parentheses for the print function, i.e., print xxx → print(xxx), in
./src/core_ocean/BGC/makedep.py
./src/core_ocean/cvmix/makedep.py
to make these files compatible with Python3.
