WPS Configuration

Create a soft link for the WPS

Load the compilers before you do anything.

spack load intel-oneapi-compilers
spack load intel-oneapi-mpi

Warning

Copy the WPS folder instead of using soft links.

cd /shared/scratch
mkdir WPS
cp -a $(spack location -i wps%intel)/. WPS/
cd WPS
ls

Jasper Installation

Jasper is needed for WPS, so you have to install it.

spack install jasper@2.0.31%intel

Check if the jasper version 2.0.31 is installed.

spack find

Alt Text

Export

Export the paths needed for WPS to work.

export JASPERLIB=$(spack location -i jasper@2.0.31%intel)/lib64
export JASPERINC=$(spack location -i jasper@2.0.31%intel)/include
export WRF_DIR=$(spack location -i wrf%intel)
export NETCDFINC=$(spack location -i netcdf-fortran%intel)/include
export NETCDFLIB=$(spack location -i netcdf-fortran%intel)/lib
export NETCDF=$(spack location -i netcdf-fortran%intel)
export NETCDFF=$(spack location -i netcdf-fortran%intel)
export LD_LIBRARY_PATH=/shared/spack/opt/spack/linux-amzn2-zen2/intel-2021.5.0/jasper-2.0.31-skcu73p6hnlgov6teechaq6muly2xrez/lib64=/shared/spack/opt/spack/linux-amzn2-zen2/intel-2021.5.0/netcdf-fortran-4.5.4-izf5fn4mw4y4mcgdjed7jp7bypsfi3s2/lib:\$LD_LIBRARY_PATH

Check if the variables are imported correctly.

echo $NETCDFINC
echo $NETCDFLIB

Copy the contents of lib and include netcdf-c to netcdf-fortran of the Intel compilers.

cp -a $(spack location -i netcdf-c%intel)/include/. $(spack location -i netcdf-fortran%intel)/include/
cp -a $(spack location -i netcdf-c%intel)/lib/. $(spack location -i netcdf-fortran%intel)/lib/

Edit configure.wps File

Configure the WPS installation.

./configure

Choose '17', for Intel serial compilers.

If you did not set the path for NETCDFINC, type Y, then paste the NETCDFINC paths as given above.

nano configure.wps

Look for WRF_LIB and add -qopenmp after -lnetcdff -lnetcdf then save.

Alt Text

Before compiling, notice the original copied files of WPS. You can view them by typing:

ls

Alt Text

Compile

The compilation of the executables can begin. The files that will be created are geogrid.exe, metgrid.exe, and ungrib.exe.

./compile > log.compile

Alt Text

After compiling, you should see new files created in the folder. You can view them by typing:

ls

Clean

If you want to start over the creation of the WPS executables, you can use the command below. Note that it will not delete any files, e.g., met_em, .nc, etc., other than those created in the compilation process.

Note

to reset WPS settings!

./clean -a
