Installation

This entry covers the entire process performed for the installation and configuration of all WRF 4.2 dependencies on a cluster with an GCC compiler. FOLLOW THE ORDER

Distributed Memory Installation

This is the installation for the distributed memory option that WRF has, please follow it exactly as it is.

module load gcc/9.3.0
module load curl/7.77.0_gcc-9.3.0
module load mpich/3.4.2_gcc-9.3.0

Create directory for libraries

To install the libraries you must do it all in one place.

mkdir wrf_install_gcc
mkdir wrf_lib_gcc

Warning

If there is a compilation error then following fix maybe implemented (Thanks to Lena Marie Müller):

sed -i 's/char *optstr/const char *optstr/g' src/libjasper/jpg/jpg_dummy.c

Distributed Memory Installation

This is the installation for the distributed memory option that WRF has, please follow it exactly as it is.

  1. Download the source code.

    mkdir WRF
cd WRF
wget https://github.com/wrf-model/WRF/archive/refs/tags/v4.2.tar.gz

  2. Export the necessary modules

    module load gcc/9.3.0 curl/7.77.0_gcc-9.3.0 mpich/3.4.2_gcc-9.3.0
export LD_LIBRARY_PATH=/home/blopezp/wrf_lib_gcc/lib:$LD_LIBRARY_PATH
export LDFLAGS=-L/home/blopezp/wrf_lib_gcc/lib
export CPPFLAGS=-I/home/blopezp/wrf_lib_gcc/include
export LD_RUN_PATH=/home/blopezp/wrf_lib_gcc/lib:$LD_RUN_PATH
export NETCDF=/home/blopezp/wrf_lib_gcc
export HDF5=/home/blopezp/wrf_lib_gcc
export JASPERLIB=/home/blopezp/wrf_lib_gcc/lib
export JASPERINC=/home/blopezp/wrf_lib_gcc/include
export PATH=/home/blopezp/wrf_lib_gcc/bin:$PATH

  3. Execute the configuration script, you will be asked two questions, choose 34 for the fist one (Enables distributed-memory processing with the GCC compiler), and 1 for the second one.

    ./configure

  4. Remove the “time” command from the following line in the configure.wrf file.

    FC = time $(DM_FC)

  5. Compile WRF, with the case you need, we recommend the case to be em_real.

    ./compile <case> | tee wrf-compilation.log

    In main/ you should see the following executables:

    • If you compile a real case:

      wrf.exe
real.exe
ndown.exe
tc.exe

    • If you compile an idealized case

      wrf.exe
ideal.exe

Compile WPS 4.2 Serial

The WRF Preprocessing System (WPS) [1] is a set of three programs whose collective role is to prepare input to the real.exe program for real-data simulations.

  1. Download the latest version of WSP

    wget https://github.com/wrf-model/WPS/archive/refs/tags/v4.2.tar.gz
tar -zxvf 4.2.tar.gz
cd WPS-4.2

  2. Load the correspondent modules and execute the configuration script, use the option 1.

    export WRF_DIR=/home/blopezp/wrf_install_gcc/WRF-4.2
./configure

  3. Edit the configuration file configure.wps

    In the section WRF_LIB = add after the following parameter -lnetcdf these parameters -liomp5 -lpthread

  4. Compile it.

    ./compile | tee wps-compilation.log
