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.

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
SAN DIEGO SUPERCOMPUTER CENTER
Science GatewaysA new initiative for the TeraGrid
• 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.

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)
• Many others interested– SID Grid– HASTAC

What Did We Learn About Common Gateway Requirements?
• 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)
SAN DIEGO SUPERCOMPUTER CENTER
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
SAN DIEGO SUPERCOMPUTER CENTER
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

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
