AB: The Southern California Earthquake Center (SCEC) is a diverse, distributed scientific community drawn together by the shared vision of understanding the cause and impact of earthquakes. As such, the domain of scientific discourse ranges from understanding the localized causes of fault ruptures to modeling how resulting seismic waves travel through the complex fault structures underlying major population centers, such as Los Angeles. SCEC is an exemplar of a class of collaborations that have come to be known as virtual organizations (VO), distributed, dynamic, multi-institutional collaborations that are bound together by a common goal. While existing collaboration tools, such as video conferencing, mailing lists and web servers, can support some of the workflow associated with a VO, many of the Project tasks require a more fundamental sharing of all elements of the IT infrastructure associated with the participants, including data, simulation models, computing and storage resources, visualization resource, etc. During the past eight years, Grid technology has emerged as an infrastructure that supports this type of resource sharing. Building on these advances, SCEC has undertaken activities in which Grids can be used to integrate the various modeling, simulation, and data collection activities of SCEC, with the goal of providing a seamless, integrated computational environment in which all aspects of geophysical elements of earthquakes can be studied, in which important information about earthquakes can be delivered to the community at large, and which promotes education and outreach about geophysics. In this presentation, we will describe the SCEC Community Modeling Environment (SCEC/CME) Grid-based infrastructure that is being built to support the scientific and education mission of SCEC. We will focus on three aspects of the current environment: (1) distributed data management, which is being used to support model validation, (2) knowledge based tools for model description, which are being used to support high-level interfaces to sophisticated modeling tasks, and (3) a distributed visualization facility, which enables remote exploration of large-scale simulation data sets. We will conclude with a description of future directions in which this environment will be taken.
