Building QuakeSim Portlets With GTLAB

The QuakeSim portal is a problem solving environment to develop a solid Earth science framework for modelling and understanding earthquakes. In this study, the authors proposed an evolutionary approach to allow TeraGrid usage in addition to the own clusters for QuakeSim portal. The approach is based on the Grid Tag Libraries And Beans (GTLAB) libraries, which encapsulate common Grid operations with reusable XML tags. GTLAB enables rapid development of grid portlets rather than typical portlet development techniques. Although it adds a new layer to programming stack, the experiments show that the performance delay is tolerable in Web applications.
