    v3 v4  
    33WRF for GRID (WRF4G) is a framework for the execution and monitoring of the WRF Modelling System (see [http://www.meteo.unican.es/work/2012_Garcia-Diez_VALUE_WRF.pdf this presentation] for an introduction to WRF) in distributed computer resources (see this presentation). It provides a flexible and easy way of designing complex experiments involving many simulations (multiple start/end dates, multi-parametric simulations, long climate runs, ...). The monitor allows a precise control of the experiment's state, where broken simulations are automatically detected and relaunched at the next submission.

    5 Given a list of computer resources the user can access, WRF4G submits the experiment to them according to the experiment needs. Users can configure different DCIs such as local PCs, stand-alone servers, PBS or SGE Clusters,etc; and use them at the same time to run different simulations of a WRF experiment. Output files are centrally stored regardless the computing resources used to run the simulations.

Output files are centrally stored regardless the DCIs used to run the simulations.

    77WRF4G separates the experiment design from the execution environment. To prepare a experiment, users are required to fill in two files: [wiki:WRF4Gexperiment_wrf4g experiment.wrf4g] which defines the WRF experiment, and [wiki:WRF4Gresources_wrf4g resources.wrf4g], where running environment and storage resources are configured. WRF4G provides a [wiki:WRF4GCommandLineInterface command line interface] that allow the users to prepare, run and monitor their experiments.
