General Info

Weather Research and Forecasting (WRF) is a numerical weather prediction (NWP) system designed to serve both atmospheric research and operational forecasting needs. source

Installation Guide

Setup environment:

mkdir WRF
cd WRF
mkdir libs
mkdir tars
vim bashrc

add:

tar -xf jasper-1.900.1.tar.gz
cd jasper-1.900.1
./configure --prefix=/home/$USER/WRF/libs/grib2
make 
make install
NetCDF
cd ~/WRF/tars
wget http://www2.mmm.ucar.edu/wrf/OnLineTutorial/compile_tutorial/tar_files/netcdf-4.1.3.tar.gz
tar -xf netcdf-4.1.3.tar.gz
cd netcdf-4.1.3
./configure --prefix=/home/$USER/WRF/libs/netcdf --disable-dap --disable-netcdf-4 --disable-shared

WRF
cd ~/WRF/tars
wget http://www2.mmm.ucar.edu/wrf/src/WRFV3.7.TAR.gz
tar -xf WRFV3.7.TAR.gz 
mv WRFV3 ..
cd ../WRFV3
./configure

You will be prompted to select config options for WRF. NetCDF should be found from environment variables set above.

for Linux x86_64 options: select 20,
then option 1 for compile nesting

After the configure step is complete, build the code with:

./compile em_real
WPS
cd ~/WRF/tars
wget http://www2.mmm.ucar.edu/wrf/src/WPSV3.7.TAR.gz
tar -xf WPSV3.7.TAR.gz
mv WPS ..
cd ../WPS
./configure 

Select option 17: Linux, with Intel, serial /w grib2

./compile
ln -sf ungrib/Variable_Tables/Vtable.GFS Vtable 

Benchmark

cd ~/WRF/tars

Download the input data for the benchmark here: GEOG.tar.gz

tar -xf GEOG.tar.gz
mv GEOG ..
cd ../GEOG
cp namelists.wps ../WPS
cd ~/WRF/tars

And here : DATA.tar.gz

tar -xf DATA.tar.gz
mv DATA ..
cd ../WPS
./link_grib.csh ../DATA/  

Build the model from the geographical data:

./geogrid.exe
./ungrib.exe
./metgrid.exe

Setup the benchmark run:

cd ~/WRF
cp GEOG/namelist.input WRFV3/run
cd WRFV3/run
ln -sf ../../WPS/met_em.d01.2015* .

Final setup step:

./real.exe

Start the benchmark with:

mpirun -np <N> -hostfile <HF> ./wrf.exe

This benchmark completed in 51 minutes on a Dell C4130 with 24 Haswell cores.
