Project: Southern California Earthquake Center (SCEC)
Description: SCEC/ITR is an interdisciplinary project that has been awarded $10 million from the National Science Foundation (NSF) to develop a Community Modeling Environment (CME), an integrated environment in which a broad range of users such as geoscientists, engineers, educators and disaster response teams can have access to first principle physics-based simulations for seismic hazard analysis. The CME environment will lead to better forecasts of when and where earthquakes are likely to occur in southern California, and how the ground will shake as a result. To achieve this goal, the CME environment must provide a means for describing, configuring, instantiating, and executing complex computational pathways that result from the composition of various earthquake simulation models. Grid is one of the key technologies for realizing the above goal. A Grid infrastructure for SCEC has been developed to provide distributed, high performance computational and data services for SCEC Pathway executions under the CME environment and the SCEC virtual organization. Grid provides fundamental services needed to locate, access, and manage geographically distributed shared resources. These services include a common Grid security infrastructure, information services to identify available computing and storage resources, and uniform resource management protocols to allocate, monitor and control these resources. With the Grid software and infrastructure, we were able to successfully instantiate and execute a compute and data intensive physics-based anelastic earthquake wave propagation computational pathway. We are in the process of expanding the infrastructure to support data provenance and workflow planning, including SCEC applications that will run on the Grid.
