  3. Welcome and Thank You • Many fine talks today from researchers or resource providers who are bringing Grid capabilities to a particular science community (atmospheric scientists, chemists, bioinformaticists, etc.) • Explore and summarize commonalities and differences - system, security, accounting, authentication/authorization and other policies and capabilities needed for production grid support • Presentations will cover: • Services provided and technologies/software used to provide them • Configuration or policy issues encountered during deployment and maintenance • Authentication and authorization approaches to support a variety of user “types” • Practical issues related to supporting workflows • Approaches to providing secure web services Science Gateways Workshop June 28, 2005

  4. Your participation will make the workshop a success • Five 90 minute sessions • Four presentations followed by a discussion • Interactive discussions encouraged! • Questions from moderators to initiate dialogue • Detailed notes will be taken • Workshop proceedings will be available as GGF informational document • Peer-reviewed papers to be published in special issue of Concurrency and Computation: Practice and Experience in early fall Science Gateways Workshop June 28, 2005

  6. Why a workshop on Science Gateways? • My day job – TeraGrid Area Director for Science Gateways • 10 Science Gateway projects in TeraGrid • I need to make these successful • New activity, funding begins this summer • Interviews conducted with all 10 teams, findings summarized • Interest in what others are doing in this area Science Gateways Workshop June 28, 2005

  7. Building a distributed system of unprecedented scale 40+ teraflops compute 1+ petabyte storage 10-40Gb/s networking Creating a unified user environment across heterogeneous resources User software environment, User support resources. Created an initial community of over 500 users, 80 PI’s. Integrating new partners to introduce new capabilities Additional computing, visualization capabilities New types of resources- data collections, instruments The TeraGrid Strategy Make it extensible! Science Gateways Workshop June 28, 2005

  8. TeraGrid Resource Partners Science Gateways Workshop June 28, 2005

  9. TeraGrid Resources Partners will add resources and TeraGrid will add partners! Science Gateways Workshop June 28, 2005

  10. Science GatewaysA new initiative for the TeraGrid • Increasing investment by communities to build their own cyberinfrastructure. • Heterogeneity • Resources - different architectures at local, national and international levels • Users- from HPC expert to K-12 student…they should all benefit from CI • Software stacks, policies • How can “centers/institutions” provide, operate, maintain in this heterogeneous world ? • Working with Gateways, TeraGrid will start to answer that question by providing generic CI services to communities. • Integration and interoperability Science Gateways Workshop June 28, 2005

  11. What are Gateways? • Gateways will • engage communities that are not traditional users of the supercomputing centers • by • providing community-tailored access to TeraGrid services and capabilities • Three examples: • Web-based Portals that front-end Grid Services that provide teragrid-deployed applications used by a community. • Coordinated access points enabling users to move seamlessly between TeraGrid and other grids. • Application programs running on users' machines but accessing services in TeraGrid (and elsewhere) • All take advantage of existing community investment in software, services, education, and other components of Cyberinfrastructure. Science Gateways Workshop June 28, 2005

  12. Workflow Composer Grid Portal Gateways • The Portal accessed through a browser or desktop tools • Provides Grid authentication and access to services • Provide direct access to TeraGrid hosted applications as services • The Required Support Services • Searchable Metadata catalogs • Information Space Management. • Workflow managers • Resource brokers • Application deployment services • Authorization services. • Builds on NSF & DOE software • Use NMI Portal Framework, GridPort • NMI Grid Tools: Condor, Globus, etc. • OSG, HEP tools: Clarens, MonaLisa Science Gateways Workshop June 28, 2005

  13. Gateways that Bridge to Community Grids • Many Community Grids already exist or are being built • NEESGrid, LIGO, Earth Systems Grid, NVO, Open Science Grid, etc. • TeraGrid will provide a service framework to enable access in ways that are transparent to their users. • The community maintains and controls the Gateway • Different Communities have different requirements. • NEES and LEAD will use TeraGrid to provision compute services • LIGO and NVO have substantial data distribution problems. • All of them require remote execution of complex workflows. Storms Forming Forecast Model Streaming Observations Data Mining On-Demand Grid Computing Science Gateways Workshop June 28, 2005

  14. Initial Focus on 10 Gateways Science Gateways Workshop June 28, 2005

  15. Expanding User Base A new generation of “users” that access TeraGrid via Science Gateways, scaling well beyond the traditional “user” with a shell login account. Projected user community size by each science gateway project. Impact on society from gateways enabling decision support is much larger! Science Gateways Workshop June 28, 2005

  16. LEAD (Linked Environments for Atmospheric Discovery ) • Storm forecasting • Modeling • Connection to sensor networks • LEAD tesbed • Workflows • Student usage Science Gateways Workshop June 28, 2005

  17. Harnessing TeraGrid for Education Example: Nanohub is used to complete coursework by undergraduate and graduate students in dozens of courses at 10 universities. Science Gateways Workshop June 28, 2005

  18. Biomedical and Biology • Building Biomedical Communities – Dan Reed (UNC) • National Evolutionary Synthesis Center • Carolina Center for Exploratory Genetic Analysis • Portals and federated databases for the Biomed research community Science Gateways Workshop June 28, 2005

  19. Neutron Science Gateway • 17 instruments • Users worldwide get “beam time” • Need access to their data and post processing capabilities Science Gateways Workshop June 28, 2005

  20. Flood Modeling/Homeland Security Gordon Wells, UT; David Maidment, UT; Budhu Bhaduri, ORNL Large-scale flooding along Brays Bayou in central Houston triggered by heavy rainfall during Tropical Storm Allison (June 9, 2001) caused more than $2 billion of damage. Science Gateways Workshop June 28, 2005

  21. OSG / one VO: CMS… Science Gateways Workshop June 28, 2005

  22. So how will we meet all these needs? • With RATS! (Requirements Analysis Teams) • Organized RATS • Collection, analysis and consolidation of requirements to jumpstart the work • And milestones Science Gateways Workshop June 28, 2005

  23. Gateways RAT concludes after 2 months • RAT team conducted interviews with all 10 Gateways • Summarized requirements for each TeraGrid working group • Draft a primer outline for new Gateways • Organize this workshop to hear from others Science Gateways Workshop June 28, 2005

  24. RAT summary • Community allocations • Group accounts / limited privileges • Need for portal accounting capabilities, but little development • On-demand scheduling • Classifications (3 types) • Portals, desktop apps, access point to other grids • User model (3 modes) • Standard, portal, community Science Gateways Workshop June 28, 2005

  25. tg-acctmgmt 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-wg Define open port ranges Firewalls 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 Actions for wg’s Science Gateways Workshop June 28, 2005

  26. Web Services (currently no wg for this) Needs further study Some Gateways (LEAD, NMBR) 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-wg Interoperability of CTSS and VDT for OSG Software installations across all TG sites Community software areas portals-wg Variety of approaches needs further analysis OGCE, in-VIGO, Clarens, Neutron Science Tomcat+Apache TG User Portal Actions for wg’s (2) Science Gateways Workshop June 28, 2005

  27. Follow on RATs formed • Web services RAT–Ivan Judson • GT4 • Portal technology RAT –John Cobb • OGCE • Clarens • In-VIGO • … • OSG RAT–Stuart Martin • OSG/CMS DAC, porting CMS apps to TG resources • Job forwarding between gatekeepers • Exposing TG resources to OSG …and vice versa !!
