WRF4G2.0
v4 v5 1 1 2 2 == Introduction == 3 WRF 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.3 WRF for GRID (WRF4G) is a framework for executing and monitoring the WRF Modeling System (see [http://www.meteo.unican.es/work/2012_Garcia-Diez_VALUE_WRF.pdf this presentation] for an introduction to WRF) in different DCIs.

The monitor allows a precise control of the experiment's state, where broken simulations are automatically detected and relaunched at the next submission. 4 4 5 Given a list of DCIs that 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 concurrently to run different simulations of a WRF experiment. Output files are centrally stored regardlessthe DCIs used to run the simulations.5 Given a list of DCIs that 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, clusters, grid resources, etc. The output files are going to be stored depending on the DCIs used to run the simulations. 6 6 7 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.
