prolog.conf file

prolog.conf file permits user configure the packets and binaries that WRF model uses on a computing resource. This file has to be in the directory which experiment.wrf4g is located. In order to help you, we show two possible examples bellow.

prolog.conf configurations:

• In this first example, we export the path directories of WPS, WRFV3 and netCDF binaries. After that, WRF4G will use there binaries (ungrib.exe ,metgrid.exe, real.exe, wrf.exe and ncdump) in order to simulate the experiments.

  [user@mycomputer~]$ cat prolog.conf
  export PATH=~/WPS:$PATH
  export PATH=~/WRFV3/run:$PATH
  export PATH=~/netCDF/bin:$PATH
  

• This second example presents a bash shell code which basically distinguishes between two resources using $GW_HOSTNAME variable.

  [user@mycomputer~]$ cat prolog.conf
  if [ $GW_HOSTNAME = mycomputer ]; then
      use WRFV3.3.1
      use netCDF4.1.3
  fi
  
  if [ $GW_HOSTNAME = mycomputer2 ]; then
      use WRFV3.3.3
      use netCDF4.3.3
  fi
  

How to know the value of all $GW_HOSTNAME variable?

[user@mycomputer~]$ wrf4g_resources | awk {'print $11'}
HOSTNAME
mycomputer
mycomputer2
