build-COAWST-docs contains information required to compile the Coupled-Ocean-Atmosphere-Wave-Sediment Transport (COAWST, https://github.com/DOI-USGS/COAWST) Modeling system on high performance computing (HPC) systems. The point of this repository is to simplify producing a COAWST executable because each HPC cluster has unique architecture. As a result, the netcdf and compiler paths often have to be set by the user, which can be time consuming to a non-expert. Current documentation is for perlmutter (https://docs.nersc.gov/systems/perlmutter/architecture/).
COAWST can be compiled using python or bash. As we are currently interested in ROMS-only applications, our python build script is tailored to ROMS. The key files are build_coawst.sh and build_roms.py.
Examples for each method are found in build_bash_pm.md and build_python_pm.md. Note that the Python build script is more user friendly, but requires removal of MCT related options in Linux-gfortran.mk to work, unless you want to take the time to install MCT. MCT is related to the coupler. An example of how to do that is shown in the bash example. The first steps for both methods require you to login to perlmutter. It is recommended to put COAWST in your home directory because scratch is scrubbed frequently. The examples are done in scratch for demonstration purposes.
