    3 WRF for GRID (WRF4G) is a framework for the execution and monitoring of the WRF Modelling System 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.

    55Given a list of computer resources the user can access, WRF4G submits the experiment to them according to the experiment needs. Users can configure different kind of resources (Their local PCs, stand-alone servers, PBS or SGE Clusters,...) 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.

    7 WRF4G 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.
