Título:Environmental Modeling using Grid Computing
Origen:University of Naples “Parthenope”
Fecha impartición: Junio de 2007.
Duración: 10 horas.
The environmental modeling is one of the most attractive fields in the grid computing technologies based application development because it involves some specific needs suited to be solved by high performance computing, distributed computing, workflow management, service oriented architectures, network of shared instruments handling and so on.
The Department of Applied Sciences of the University of Naples “Parthenope” joined the historical knowledge in environmental modeling and applied mathematics with the strongly computer science oriented grid computing components and applications development field. In this contest a grid architecture was designed and developed spreading over it open source environmental numerical models building a virtual laboratory for meteo-marine forecasts, now casts and scenario analysis.
The developed application runs dynamically thanks to a from scratch developed job flow scheduler (JFSS, Job Flow Scheduler Service), resource broker (RBS: Resource Broker Service), five dimensional data distribution service (GDDS: Grads Data Distribution Service) and an instrument virtualization service (IS, Instrument Service) using Globus Toolkit version 4 web services. The actual grid application integrates the WRF (Weather Research and Forecast) forcing in one way mode both the Princeton Ocean Model (POM) and the WaveWatch III ocean wave model and the Weather Research and Forecast (WRF) model forcing the Comprehensive Air-Quality Model with Extensions (CAMx). The aim of this seminar suite is to provide a theoretical and practical skills on grid enabling environmental models using both the approaches based on remote execution via specific protocols as the Globus GT2 does and a service oriented architecture where different models are coupled thanks the GT4 provided web services.
