  1. Advancing Scientific Discovery through TeraGrid Adapted from S. Lathrop’s talk in SC’07 www.teragrid.org

  2. 11 Resource Providers, One Facility Grid Infrastructure Group (UChicago) UW PSC UC/ANL NCAR PU NCSA UNC/RENCI IU Caltech ORNL U Tenn. USC/ISI SDSC LSU TACC Resource Provider (RP) Software Integration Partner

  3. TeraGrid Objectives • DEEP Science: Enabling Petascale Science • Make Science More Productive through an integrated set of very-high capability resources • Address key challenges prioritized by users • WIDE Impact: Empowering Communities • Bring TeraGrid capabilities to the broad science community • Partner with science community leaders - “Science Gateways” • OPEN Infrastructure, OPEN Partnership • Provide a coordinated, general purpose, reliable set of services and resources • Partner with campuses and facilities

  4. TeraGrid Resources • Computing - over 250 Tflops today and growing • 400 Tflop system comes on-line in January at TACC • U Tennesee system to come on-line in 2008 • Centralized help desk for all resource providers • Visualization - Remote visualization servers and software • Data • Allocation of data storage facilities • Over 100 Scientific Data Collections • Access • Shibboleth testbed to facilitate campus access • Central allocations mechanism • Human Support • Advanced Support for TeraGrid Applications (ASTA) • Education and training events and resources • Over 20 Science Gateways

  5. Advanced Support for TeraGrid Applications Virtualized Resources, Ensembles:FOAM Climate Model Liu (UWisc) Coupled Simulation: Full Body Arterial Tree Simulation Karniadakis (Brown) Sources: Ian Foster (UC/ANL), Mike Papka (UC/ANL), George Karniadakis (Brown). Images by UC/ANL.


  6. Requesting Allocations of Time • TeraGrid resources are provided for free to academic researchers and educators • Development Allocations Committee (DAC) for start-up accounts up to 30,000 hours of time are requests processed in two weeks - start-up and courses • Medium Resource Allocations Committee (MRAC) for requests of up to 500,000 hours of time are reviewed four times a year • Large Resource Allocations Committee (LRAC) for requests of over 500,000 hours of time are reviewed twice a year

  7. TeraGrid Usage Specific Allocations Roaming Allocations 33% Annual Growth 200 Normalized Units (millions) 100 TeraGrid currently delivers an average of 420,000 cpu-hours per day -> ~21,000 CPUs DC Dave Hart (dhart@sdsc.edu)

  8. TeraGrid Usage Modes in CY2006 500 Grid-y Users

  9. Science GatewaysBroadening Participation in TeraGrid Workflow Composer • Increasing investment by communities in their own cyberinfrastructure, but heterogeneous: • Resources • Users – from expert to K-12 • Software stacks, policies • Science Gateways • Provide “TeraGrid Inside” capabilities • Leverage community investment • Three common forms: • Web-based Portals • Application programs running on users' machines but accessing services in TeraGrid • Coordinated access points enabling users to move seamlessly between TeraGrid and other grids.

  10. Gateways are growing in numbers 10 initial projects as part of TG proposal >20 Gateway projects today No limit on how many gateways can use TG resources Prepare services and documentation so developers can work independently Open Science Grid (OSG) Special PRiority and Urgent Computing Environment (SPRUCE) National Virtual Observatory (NVO) Linked Environments for Atmospheric Discovery (LEAD) Computational Chemistry Grid (GridChem) Computational Science and Engineering Online (CSE-Online) GEON(GEOsciences Network) Network for Earthquake Engineering Simulation (NEES) SCEC Earthworks Project Network for Computational Nanotechnology and nanoHUB GIScience Gateway (GISolve) Biology and Biomedicine Science Gateway Open Life Sciences Gateway The Telescience Project Grid Analysis Environment (GAE) Neutron Science Instrument Gateway TeraGrid Visualization Gateway, ANL BIRN Gridblast Bioinformatics Gateway Earth Systems Grid Astrophysical Data Repository (Cornell)

  11. TeraGrid as a Social Network • Annual TeraGrid conference - TeraGrid ‘08 - Las Vegas - June • LRAC/MRAC liaisons • SGW community very successful • Transitioning to consulting model • CI Days - campus outreach • OSG/Internet2/NLR/EDUCAUSE/MSI-CIEC partnership • HPC University • OSG, Shodor, Krell, OSC, NCSI, MSI-CIEC partnership • Education and Outreach • Engaging thousands of people
