  1. Science Gateways on the TeraGrid Nancy Wilkins-Diehr TeraGrid Area Director for Science Gateways SDSC Director of Consulting, Documentation, Training San Diego Supercomputer Center wilkinsn@sdsc.edu

  2. What is the TeraGrid? • NSF-funded facility to offer high end compute, data and visualization resources to the nation’s academic researchers

  3. TeraGrid Technology Computation Visualization 100+ Teraflops Computation Memory Intensive Resources Data 18.8 Petabytes Storage 40gigabit/second cross-country network

  4. Over 100 Tflops in Computing Power

  5. TeraGrid Resources Available to Academic Researchers at No Cost • TeraGrid creates integrated, persistent, and pioneering computational resources that significantly improve our nation’s ability and capacity to gain new insights into our most challenging research questions and societal problems. • Proposal-based access, researchers can use resources at no cost • Collaborative opportunities, but Principal Investigators must be from the U.S.

  6. TeraGrid PI’s By Institution as of May 2006 Blue: 10 or more PI’s Red: 5-9 PI’s Yellow: 2-4 PI’s Green: 1 PI TeraGrid PI’s

  7. Gateways are part of TeraGrid’s 3-pronged strategy to further science • DEEP Science: Enabling Terascale Science • Make science more productive through an integrated set of very-high capability resources • Advanced Support for TeraGrid Applications (ASTA) projects • WIDE Impact: Empowering Communities • Bring TeraGrid capabilities to the broad science community • Science Gateways • OPEN Infrastructure, OPEN Partnership • Provide a coordinated, general purpose, reliable set of services and resources • Grid interoperability working group

  8. Science GatewaysA new initiative for the 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.

  9. 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) Many others interested SID Grid HASTAC Gateways are growing in numbers

  10. Accounting Support for accounts with differing capabilities Ability to associate compute job to a individual portal user Scheme for portal registration and usage tracking Dynamic accounts Security Community account privileges Need to identify human responsible for a job for incident response Acceptance of other grid certificates Web Services Many will build on the Globus Toolkit, but additional interfaces may be needed Web Service security Interfaces to scheduling and account management are common requirements Software Interoperability of software stacks between TeraGrid and peer grids Software installations for gateways across all TG sites Community software areas Management (pacman, other options) What Did We Learn About Common Gateway Requirements?

  11. National Virtual ObservatoryFacilitating Scientific Discovery • Access to telescope images from around the world • NVO provides access to combined sky surveys • Different views of the same cosmological phenomenon can reveal new insights • New science enabled by enhancing access to data and computing resources • Data correlation • Understanding of physical processes • Identification of new phenomenon • NVO is a set of tools used to exploit the data avalanche

  12. Linked Environments for Atmospheric Discovery • Providing tools that are needed to make accurate • predictions of tornados and hurricanes • Meteorological data • Forecast models • Analysis and visualization tools • Data exploration and Grid workflow

  13. Would development of a gateway help your research? • Think about your current bottlenecks • What would you like to explore if only you had • Lots of disk • Lots of compute resources • Powerful analysis capabilities • A nice interface to information • www.teragrid.org • Nancy Wilkins-Diehr, wilkinsn@sdsc.edu
