    3 == WRF4G Components ==
     3WRF4G 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.
    44
    5 WRF4G is a software that has 2 main components, one runs in the '''user's interface (UI)''' (usually their PCs) and manages the experiments and the resources used by the experiment. This component is in charge of the design, execution and monitoring of experiments. Once submitted to a resource, WRF4G start to run in a '''Computing Node'''.
    6 
    7 A user can use the following resources as Computing Nodes:
    8 * The same UI where their are running the WRF4G framework.
    9 * Workstation or stand-alone server.
    10 * Cluster (PBS, SGE, SLURM)
    11 * Mainframe HPC.
    12 * Grid infrastructures (currently supported globus and gLite)
    13 
    14 In the examples shown bellow, we will use only a Computing Node that will be the UI where the framework is running.
     5Although 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.

    167== Required Software ==
    178
    18 WRF4G need the following software preinstalled both in the UI and the Computing Nodes:
     9WRF4G need the following software preinstalled both in the UI and the CR:
    1910
     11 * '''x86_64 Linux'''
    2012 * '''Python''', version >= 2.4 and < 3.0.
    2113 * '''MySQLdb''': Ubuntu: sudo apt-get install python-mysqldb. Centos/RHEL: yum install MySQL-python
