GriPhyN Project Paul Avery, University of Florida, Ian Foster, University of Chicago NSF Grant ITR-0086044 Research Objectives Significant Results Approach Broader Impact  Provide tools to manage, discover, & apply peta-scale data and software resources  Enable Grids to be used by scientists as simply as personal workstations  A uniform virtual data model to express, discover and manipulate scientific datasets and workflow. Advanced planners, executors, monitors, and fault recovery to make the Grid like a workstation  Intensive Experiment/CS collaboration  Partnership with iVDGL and PPDG to deploy national Grid: http://www.ivdgl.org/grid2003  Unified language to express data transformation benefits all sciences  Lowered barrier to computation, increased collaboration and communication  Benefits to education – enhance discovery and learning of scientific processes  Virtual data language, Virtual Data Toolkit (VDT)  Grid tools utilized by multiple sciences (ATLAS, CMS, LIGO, SDSS, Biology, others)  Collaboration with other NSF & DOE supported projects to build (inter)national Grid: Grid2003  Intensive student involvement and outreach impact: QuarkNet, 2004 Grid Summer School discovery Science Review Production Manager Researcher discovery sharing instrument Users Virtual Data storage element Grid Grid Fabric storage element storage element composition planning data Planning Execution Virtual Data Toolkit Services Chimera virtual data system Pegasus planner DAGman Globus Toolkit Condor Ganglia, etc. Monitoring and Prediction ProductionAnalysis param s exec. dat a
