Brief TeraGrid Overview and Expectations of Science Advisory Board

1. Brief TeraGrid Overview and Expectations of Science Advisory Board John Towns TeraGrid Forum Chair Director of Persistent Infrastructure National Center for Supercomputing Applications University of Illinois jtowns@ncsa.illinois.edu

2. The Vision of TeraGrid • Three part mission: • support the most advanced computational science in multiple domains • empower new communities of users • provide resources and services that can be extended to a broader cyberinfrastructure • TeraGrid is… • an advanced, nationally distributed, open cyberinfrastructure comprised of supercomputing, storage, and visualization systems, data collections, and science gateways, integrated by software services and high bandwidth networks, coordinated through common policies and operations, and supported by computing and technology experts, that enables and supports leading­edge scientific discovery and promotes science and technology education • a complex collaboration of over a dozen organizations and NSF awards working together to provide collective services that go beyond what can be provided by individual institutions

3. What is TeraGrid?(simple definition) A complex collaboration of over a dozen organizations working together to provide cyberinfrastructure that goes beyond what can be provided by individual institutions, to improve research productivity and enable breakthroughs not otherwise possible.

4. 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

5. What is the TeraGrid? • An instrument that delivers high-end IT resources/services: computation, storage, visualization, and data/services • a computational facility – over a PetaFLOP in parallel computing capability • a data storage and management facility - over 20 PetaBytes of storage (disk and tape), over 100 scientific data collections • a high-bandwidth national data network • A service: help desk and consulting, Advanced Support for TeraGrid Applications (ASTA), education and training events and resources • Something you can use without financial cost • research accounts allocated via peer review • Startup and Education accounts automatic • World’s largest distributed cyberinfrastructure for scientific research • supported by National Science Foundation

6. 11 Resource Providers, One Facility Grid Infrastructure Group (UChicago) UW UC/ANL PSC NCAR PU NCSA Caltech UNC/RENCI IU ORNL USC/ISI NICS SDSC LONI TACC Resource Provider (RP) Software Integration Partner Network Hub

7. TeraGrid Resources and Services • Computing • more than one petaflop of computing power today and growing • 500 Tflop Ranger (Sun Constellation) at Texas Advanced Computing Center (TACC) • 1.03 PFlop Kraken (Cray XT5) at National Institute for Computational Sciences (NICS), University of Tennessee • Remote visualization servers and software • 60 TFlop condor-based viz resource at Purdue University • Data • allocation of data storage facilities • over 100 Scientific Data Collections • Central allocations process • Technical Support • central point of contact for support of all systems • Advanced Support for TeraGrid Applications (ASTA) • education and training events and resources • over 30 Science Gateways

8. How is TeraGrid Organized? • TG is set up like a large cooperative research group • evolved from many years of collaborative arrangements between the centers • still evolving! • Federation of 12 awards • Resource Providers (RPs) • provide the computing, storage, and visualization resources • Grid Infrastructure Group (GIG) • central planning, reporting, coordination, facilitation, and management group • Strategically lead by the TeraGrid Forum • made up of the PI’s from each RP and the GIG • led by the TG Forum Chair, who is responsible for coordinating the group (elected position) • John Towns – TG Forum Chair • responsible for the strategic decision making that affects the collaboration • Day-to-Day Functioning via Working Groups (WGs): • each WG under a GIG Area Director (AD), includes RP representatives and/or users, and focuses on a targeted area of TeraGrid

10. Expectations of SAB • SAB is joint advisory for both NSF and TeraGrid • Barry will tell you what he wants from you  • TeraGrid Expectations • provide guidance on strategic directions • are we going in the right direction? • are we going about things in the most effective way? • indicate new areas we should be investigating • are there things out there we have been missing • guidance going into transition to XD • Interaction mode: • this is not a formal review but friendly advice • be honest with us; we don’t expect NSF to hold too much of this against us
