Weather Research & Forecasting (WRF) Model is a mesoscale numerical weather prediction system designed to serve both operational forecasting and atmospheric research needs. It features multiple dynamical cores, a 3-dimensional variational (3DVAR) data assimilation system, and a software architecture allowing for computational parallelism and system extensibility. WRF is suitable for a broad spectrum of applications across scales ranging from meters to thousands of kilometers. For more info, see here.

Getting Started
1. Clone the WRF Git
$ git clone https://github.com/wrf-model/WRF.git ...
2. Load prerequisite modules
$ module load intel/2019.1.144 hpcx/2.4.0 hdf5/1.10.4-hpcx-2.4.0 netcdf/4.6.2-hpcx-2.4.0
3. Add environemt variables
$ export WRFIO_NCD_LARGE_FILE_SUPPORT=1 $ export NETCDF=$NETCDF_DIR
4. Configure
Notes:
-xHost will not work on AMD
AVX2 may need to change to AVx512
remove
“Edit mpicc...” means edit configure.wrf; I remove the “-f90=$(SFC)” option from mpif90 and the “-cc=$(SCC)” option from mpicc, because HPC-X (Open MPI) doesn’t need those options. I would change AVX2 to AVX512 if I only intend to run WRF on SKL; otherwise leave it as AVX2
