How to run a demo experiment
- Install WRF4G:
$ wget -O- https://meteo.unican.es/work/WRF4G/install.sh | bash

====================================
Installation of WRF4G 2.0.0 is done!
====================================
In order to work with WRF4G you have to enable its
environment with the command:
. /home/user/wrf4g/bin/wrf4g_init.sh
You need to run the above command on every new shell you
open before using WRF4G, but just once per session.
[user@mycomputer~]$ . /home/user/wrf4g/bin/wrf4g_init.sh
- Start up WRF4G :
[user@mycomputer~]$ wrf4g start
Starting DRM4G ....
OK
Starting WRF4G_DB (MySQL) ...
OK
- Show information about all available resources and their host :
[user@mycomputer~]$ wrf4g resource list
RESOURCE STATE
localmachine enabled
[user@mycomputer~]$ wrf4g host list
HID ARCH JOBS(R/T) LRMS HOSTNAME
0 x86_64 0/0 fork localmachine
[user@mycomputer~]$ wrf4g host list 0
HID ARCH JOBS(R/T) LRMS HOSTNAME
0 x86_64 0/0 fork localmachine

default 0/0 0 0 1 1
- Define an experiment called test from a template :
[user@mycomputer~]$ wrf4g exp test define --from-template=single
- Take a look at test experiment configuration :
[user@mycomputer~]$ cat test/experiment.wrf4g
