2. SAN DIEGO SUPERCOMPUTER CENTER Welcome to San Diego

3. SAN DIEGO SUPERCOMPUTER CENTER and welcome to SDSC Founded in 1986 Cray XMP performs 1 billion ops (1 Gflop) “We’re totally utilized with typically 30-40 people running at one time – sometimes 50-60 people!”

4. SAN DIEGO SUPERCOMPUTER CENTER SDSC today DataStar performs at over 15,000 Gflops Thousands of scientists computing, but impact is even greater through software distributions and data collection hosting NSF competition for 1 Pflop machine (1 million times faster than the original XMP 20 years ago)

5. SAN DIEGO SUPERCOMPUTER CENTER Unexpected Synergies Across Disciplines Astronomy and dendrochronology Trees in the Sierra Nevada and the beginnings of civilization Collaborations as a result of this institute

6. SAN DIEGO SUPERCOMPUTER CENTER Astronomy and Dendrochronology Dr. Andrew Ellicott Douglass from U of Arizona was an astronomer studying sunspot cycles He sought a way to tie the cycles to weather patterns on Earth Data recorded in tree rings as a way to validate his astronomical theory

7. SAN DIEGO SUPERCOMPUTER CENTER Ancient Bristlecone Pines and the beginning of civilization Dr. Edmund Schulman assisted Dr. Douglass and focused on climate research His search for older trees led to the discovery of 4,700 year old bristlecone pines Subsequent recalibration of radiocarbon dating process Reinterpretation of cultural diffusion in the Mediterranean and Europe

10. SAN DIEGO SUPERCOMPUTER CENTER My Talk Today What are Science Gateways? Why TeraGrid and Gateways? Initial Strategy Implementation Details –Issues to address when using TeraGrid Future growth

11. SAN DIEGO SUPERCOMPUTER CENTER Gateways are part of TG’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 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

12. SAN DIEGO SUPERCOMPUTER CENTER Science Gateways A 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. Workflow Composer

13. SAN DIEGO SUPERCOMPUTER CENTER Initial Focus on 10 Gateways

14. SAN DIEGO SUPERCOMPUTER CENTER National Virtual Observatory Facilitating Scientific Discovery Astronomy is increasingly a data-rich science New science enabled by enhancing access to data and computing resources Ease of use in locating, retrieving, and analyzing data from archives and catalogs worldwide NVO is a set of tools used to exploit the data avalanche

15. SAN DIEGO SUPERCOMPUTER CENTER NanoHub Harnesses TeraGrid for Education Nanohub is used to complete coursework by undergraduate and graduate students in dozens of courses at 10 universities. Currently serves over 1000 users.

17. SAN DIEGO SUPERCOMPUTER CENTER spruce.teragrid.org Special Priority and Urgent Computing Environment

18. SAN DIEGO SUPERCOMPUTER CENTER Biomedical and Biology Gateway Led by Dan Reed, Renaissance Computing Institute, North Carolina Supports –Distributed collaboration –Multi-site data access –Computational tools for local or remote execution –Grid and cluster interoperability Will provides access to –Common sequence and protein structure databases –Over 140 software packages

19. SAN DIEGO SUPERCOMPUTER CENTER Linked Environments for Atmospheric Discovery LEAD 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

20. SAN DIEGO SUPERCOMPUTER CENTER 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 Cornell Many others interested –SID Grid –HASTAC

21. SAN DIEGO SUPERCOMPUTER CENTER NCAR Earth System Grid ESG originally a distributed data management/access system but it has evolved into more. User registration, authorization controls, and metrics tracking CCSM model source, initialization datasets, post- processing codes, and analysis and visualization tools. Prototypes of model- submission environments, eventually real- time tracking of model status along with references to available output datasets. "science gateway" for climate research. Expect to see more model runs at higher- resolution and with greater component scope.

22. SAN DIEGO SUPERCOMPUTER CENTER So how will we meet all these needs? With RATS! (Requirements Analysis Teams) Collection, analysis and consolidation of requirements to jump start the work –Interviews with 10 Gateways –Common user models, accounting needs, scheduling needs Summarized requirements for each TeraGrid working group –Accounting, Security, Web Services, Software Areas for more study identified Primer outline for new Gateways in progress And milestones

23. SAN DIEGO SUPERCOMPUTER CENTER Implications for TeraGrid working groups Accounting –Support for accounts with differing capabilities –Ability to associate compute job to a individual portal user –Scheme for portal registration and usage tracking –Support for OSG’s Grid User Management System (GUMS) –Dynamic accounts Security –Community account privileges –Need to identify human responsible for a job for incident response –Acceptance of other grid certificates –TG-hosted web servers, cgi-bin code Web Services –Initial analysis completed 12/05 –Some Gateways (LEAD, Open Life Sciences) have immediate needs –Many will build on capabilities offered by GT4, but interoperability could be an issue –Web Service security –Interfaces to scheduling and account management are common requirements Software –Interoperability of software stacks between TG and peer grids –Software installations for gateways across all TG sites –Community software areas –Management (pacman, other options)

24. SAN DIEGO SUPERCOMPUTER CENTER Gateway Web Services Needs Interfaces provided by the TeraGrid The list of services that have been identified by the gateways developers includes: –Resource Status Service (both polling and pub/sub) –Job Submission Interface The gateways expect this to be provided by WS-GRAM –Job Tracking Interface (Both polling and pub/sub) –File/Data Staging Interface –Retrieve Usage Information –Retrieve Inca Info –Advanced Reservation Interface –Cross-site Run interface –Pushing DN to an RP interface Interfaces provided by the Gateways The list of services that have been identified by the gateways developers and the TeraGrid Security group includes: –Retrieve user information for a job –Retrieve accounting information/statistics –Provides the necessary means to track down problem job submissions, identify malicious users, and tabulate accounting and logging information for reporting needs by the RPs. It is expected that the information provided for the first interface is simply the (resource, job id) that is known by both parties at job submission time. This interface provides sufficient user information for the RPs to deal with the situation at hand, and possibly identifies another interface that should be provided by the gateways: –Don't submit jobs from the user who submitted job (resource, job id), until we say it's Ok. –The accounting interface requires no information, but returns sufficient accounting information and statistics to report to funding agencies, program managers, etc.
