The Vision of TeraGrid
•Three part mission:
–support the most advanced computational science in multipledomains
–empower new communities of users
–provide resources and services that can be extended to a broadercyberinfrastructure
•TeraGrid is…
–an advanced, nationally distributed, open cyberinfrastructurecomprised of supercomputing, storage, and visualization systems,data collections, and science gateways, integrated by softwareservices and high bandwidth networks, coordinated through commonpolicies and operations, and supported by computing and technologyexperts, that enables and supports leadingedge scientific discoveryand promotes science and technology education
–a complex collaboration of over a dozen organizations and NSFawards working together to provide collective services that gobeyond what can be provided by individual institutions

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 computingcapability
–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 forTeraGrid Applications (ASTA), education and training events andresources
•Something you can use without financial cost
–research accounts allocated via peer review
–Startup and Education accounts automatic
•World’s largest distributed cyberinfrastructure for scientificresearch
–supported by National Science Foundation

How is TeraGrid Organized?
•TG is set up like a large cooperative research group
–evolved from many years of collaborative arrangements between thecenters
–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 thegroup (elected position)
• John Towns – TG Forum Chair
–responsible for the strategic decision making that affects thecollaboration
•Day-to-Day Functioning via Working Groups (WGs):
–each WG under a GIG Area Director (AD), includes RP representativesand/or users, and focuses on a targeted area of TeraGrid

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 muchof this against us
