Installing WRF from scratch in an HPC using Intel Compilers

The Weather Research and Forecasting (WRF) Model is a mesoscale numerical weather prediction system utilized worldwide for operational forecasts and research purposes.

Here is the installation of the WRF 4.2.1 model using Intel compilers. It will be helpful to those who want to install WRF from scratch in an HPC environment. Some of the steps may not be required depending on your HPC environment.

Required Libraries

  1. zlib
  2. HDF5
  3. NetCDF
  4. JasPer

Generally, these libraries should be their (except for Jasper). If you do not have those then install using the steps below or you directly start from Step 4:

Setting up the environemnt for Intel compilers

export CC=icc
export FC=ifort
export F90=ifort
export CXX=icpc

1. Installing zlib

mkdir wrf_install_intel
cd wrf_install_intel/
wget https://zlib.net/zlib-1.2.11.tar.gz

tar xvf zlib-1.2.11.tar.gz
cd zlib-1.2.11/

./configure --prefix=/home/wrf/wrf_libs_intel/
make
make install

2. Installing HDF5

cd ../
wget https://hdf-wordpress-1.s3.amazonaws.com/wp-content/uploads/manual/HDF5/HDF5_1_12_0/source/hdf5-1.12.0.tar.gz
./configure --prefix=/home/wrf/wrf_libs_intel/ --with-zlib=/home/wrf/wrf_libs_intel/ --enable-fortran
make 
make install

3. Installing NetCDF

cd ../
wget https://www.unidata.ucar.edu/downloads/netcdf/ftp/netcdf-c-4.7.4.tar.gz
tar xvf netcdf-c-4.7.4.tar.gz 
cd netcdf-c-4.7.4/

export LD_LIBRARY_PATH=/home/wrf/wrf_libs_intel/lib
export LDFLAGS=-L/home/wrf/wrf_libs_intel/lib
export CPPFLAGS=-I/home/wrf/wrf_libs_intel/include
./configure --prefix=/home/wrf/wrf_libs_intel/ 
make
make install

cd ../
wget https://www.unidata.ucar.edu/downloads/netcdf/ftp/netcdf-fortran-4.5.3.tar.gz
tar xvf netcdf-fortran-4.5.3.tar.gz 
cd netcdf-fortran-4.5.3/
./configure --prefix=/home/wrf/wrf_libs_intel/ 
make
make install

4. Installing JasPer

cd ../
wget https://www.ece.uvic.ca/~frodo/jasper/software/jasper-1.900.29.tar.gz
tar xvf jasper-1.900.29.tar.gz
./configure --prefix=/home/wrf/wrf_libs_intel/ 
make
make install

WRF Install

export NETCDF=/home/wrf/wrf_libs_intel/
export HDF5=/home/wrf/wrf_libs_intel/
wget https://github.com/wrf-model/WRF/archive/v4.2.1.tar.gz
tar xvf v4.2.1.tar.gz
cd WRF-4.2.1/
./configure 

Output:

checking for perl5... no
checking for perl... found /usr/local/bin/perl (perl)
Will use NETCDF in dir: /home/wrf/wrf_libs_intel/
Will use HDF5 in dir: /home/wrf/wrf_libs_intel/
PHDF5 not set in environment. Will configure WRF for use without.
Will use 'time' to report timing information


If you REALLY want Grib2 output from WRF, modify the arch/Config.pl script.
Right now you are not getting the Jasper lib, from the environment, compiled into WRF.

Edit configure.wrf

Edit here using your favorite editor:

DM_FC           =       mpiifort
DM_CC           =       mpiicc

Compile the code

./compile -j 4 em_real 2>&1 | tee compile.log

This step will take around 30-45 min to complete. Be patient!

Sometimes, you have again re-run the compile code, if you do not get this as the output.
