Create Directory for Libraries

To install the libraries, all must be placed in the same location.

export DIR=$PWD
mkdir wrf_install_gcc
mkdir wrf_lib_gcc

Distributed Memory Installation

Restart the environment by exiting and re-entering the terminal.

  1. Export the necessary modules and variables, set the $DIR variable exactly as before.

    module load compiler/2022.0.2
module load openmpi/4.1.2_gcc-11.2.0
module load gcc/11.2.0
module load curl

export LD_LIBRARY_PATH=$DIR/wrf_lib_gcc/lib:$LD_LIBRARY_PATH
export LDFLAGS=-L$DIR/wrf_lib_gcc/lib
export CPPFLAGS=-I$DIR/wrf_lib_gcc/include
export LD_RUN_PATH=$DIR/wrf_lib_gcc/lib:$LD_RUN_PATH
export NETCDF=$DIR/wrf_lib_gcc
export HDF5=$DIR/wrf_lib_gcc
export JASPERLIB=$DIR/wrf_lib_gcc/lib
export JASPERINC=$DIR/wrf_lib_gcc/include
export PATH=$DIR/wrf_lib_gcc/bin:$PATH

  2. Execute the configuration script inside the WRF folder. You will be asked two questions: choose 34 for the first one (Distributed-memory processing with GCC compiler), and 1 for the second one.

    ./configure

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

    FC = time $(DM_FC)

# Change to this, save and exit
FC = $(DM_FC)

  4. Compile WRF with the case you need (recommended: em_real).

    ./compile <case> >& compile.log &
tail -f compile.log  # to see the progress

    If compilation is successful, you should see the following executables in main/:

    • For real case compilation:

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

    • For idealized case compilation:

      wrf.exe
ideal.exe
