WRF4G can be installed in any Linux Computer. It provides the services needed to prepare, run and monitor experiments and it can manage many computing resources and use them at the same time to run different simulations of a WRF experiment.
Although in the following examples we will use the same computer to manage the experiments and to run them, usually scientists use a computer to prepare and manage the experiments (where WRF4G has to be installed) and different computing resources to run them (PBS or SGE Clusters, HPC infrastructures, stand-alone servers). We call User Interface (UI) to the computer where WRF4G is installed and Computing Resources (CR) to the nodes where a WRF experiment can run. In the following experiments the computer where the UI role is installed will act as CR.
WRF4G needs the following software preinstalled on both UI and CR:
WRF4G has been run only in 64bits platforms and currently has been tested under the following O.S.:
Download and unpack the distribution file ?WRF4G.tar.gz to the installation directory, for example your $HOME directory.
[user@mycomputer~]$ cd $WRF4G_INSTALL_PATH (i.e cd $HOME) [user@mycomputer~]$ wget www.meteo.unican.es/work/WRF4G.tar.gz [user@mycomputer~]$ tar xzvf WRF4G.tar.gz
Setup the WRF4G user environment. (To avoid typing the export command every time you want to use WRF4G, it is advisable to copy these lines in $HOME/.bashrc)
[user@mycomputer~]$ export WRF4G_LOCATION=$WRF4G_INSTALL_PATH/WRF4G [user@mycomputer~]$ export PATH=$WRF4G_LOCATION/bin:$PATH
The installation process provides the UI with:
