  9. North Carolina Bioportal • Principal collaborators: John McGee and Lavanya Ramakrishnan • Features • access to common bioinformatics tools • extensible toolkit and infrastructure • OGCE and National Middleware Initiative (NMI) • leverages emerging international standards • remotely accessible or locally deployable • packaged and distributed with documentation • National reach and community • TeraGrid deployment • Portals hosted at RENCI and NCSA • Education and training • hands-on workshops across North Carolina • clusters, Grids, portals and bioinformatics

  10. PittGrid: Portal • PittGrid Portal is built using OGCE Portal Toolkit • Supports PittGrid’s Globus 4 and Condor services • PittGrid users can login to the portal to submit and monitor their jobs • Job submission portlet and Condor job submission portlet allows user to submit their job online to Globus and Condor, respectively • GPIR is used to provide information services • OGCE has worked closely with Senthil Natarajan (Pitt) and Matt Farrellee (UW) on enhancements to Condor portlets and BirdBath.

  11. UNC-Charlotte Visual Grid Portal Project Lead: Prof. Barry Wilkinson Portal Developer: Jeremy Villalobos

  12. Summary of OGCE Collaborations • Mixture of • Portal builders for hire (TUP, TIGRE) • Direct collaboration, consulting with existing projects (OGCE person on-site) • Portal developer off the street • OGCE software used includes portlet components, libraries, and services. • Wide variety of projects, personnel, funding levels, and expectations • Some have many full time developers for all project aspects: from portal cosmetics to grid system admin • Some have one tech person: a grad student or system admin • Interesting requirements: • Expected: TeraGrid access, support for SRB, condor and traditional schedulers. • 1-100 codes, 1-1000 users, 1-1,000,000,000,000 bytes of data • Unexpected: AJAX, virtual workspaces, integration of multiple semi-independent portals (portal federation)

  13. OGCE Portal Software and Services

  14. OGCE Software Development Overview Portal Container • Portlets are our central technology • JSR 168 standard. • Standard compliant portlets allow reuse of portal code between projects. • This should definitely be used in the TeraGrid Science Gateway community. • OGCE devotes significant effort to services, tools, and libraries. Portlets Grid Libraries Service Service Service Grid Infrastructure

  15. Why Portlets? Use of Standards • These are standard components for building (Java) portals out of reusable parts. • We work within a larger community • Commercial efforts • Open Source: GridSphere, uPortal/JA-SIG, Pluto, StringBeans, Jetspeed2, eXo • Supporting Apache portals efforts (Jetspeed2, Portlet Bridges efforts) • We participate in standards development. • JSR 286 expert committee, GGF/OGF • But Grids have their own problems and requirements that we must solve.

  16. Community Leadership, Outreach, and Participation

  17. GCE Workshops at Supercomputing • Open calls to the portal community • GCE05 held in Seattle, November 18th 2005 • http://pipeline0.acel.sdsu.edu/mtgs/gce05/ • 5 invited talks (judged by tech committee) • 11 accepted posters • 50+ participants • Expanded, re-reviewed papers to appear in Concurrency and Computation • GCE06 scheduled Nov 12-13, 2006 in Tampa • Selected as part of SC06 workshop peer-review process • Call for papers just went out • http://www.cogkit.org/GCE06/

  18. Plenary Session Poster Session

  19. Science Portals in 2010 and Beyond What we want to make happen and how

  20. VirtualizingGrid Access • As TeraGrid expands it will become a “utility” that extends our desktop with huge resources. • Portals and Gateways will provide access to: • Virtualized Storage: • An “infinite capacity” data and replica management service. • Users will not manage data but have access through personal metadata catalogs. • Virtualized Computation: • Portal is a front-end to services that automatically allocate and schedule computational cycles as needed. • User focuses on science … not resource management.

  21. Knowledge Discovery and Delivery Search Agent Chem Info Crawler • Agents for Search • Portals support data discovery. • We will be able to pose queries for future discovery • “I am interested in all new data relating to chemical structures of the following form … When you find them, run the following analysis workflow against it and notify me if the result is interesting”. • “Mash Ups” show how to integrate data from multiple sources. • Combine “big” data (Google) and “little” data (my GPS data) Candidate event discovery event Analysis workflow

  22. Validating Scientific Discovery • The portal is an integral part of the process of computational science • Serves as an active repository of data provenance • The portal records each computational experiment that a user initiates • Disks are cheap, so why not record everything? • Provides a complete audit trail of the experiment or computation • Published results will include link to provenance information for repeatability and transparency. • Many portals have done this on a smaller scale • CIMA, PubChem + NIH cancer screening centers, LEAD, SERVO/Quakesim, ... • But this should be standard practice. • Should be persistently stored in journal catalogs

  23. Grid Portal Software Development • Science portal and gateway research have exciting opportunities. • We must balance these research opportunities with nuts-and-bolts software development. • We can make an accurate short term forecast for the next generation of portals.

  24. Portal Software Center Directly supporting science gateways through as a software service provider

  25. Supporting TeraGrid Gateways: a No-Cost Extension Activity • The NSF has a significant investment in the success of the TeraGrid Science Gateways. • Current Gateway efforts focus on integration of gateways with the TeraGrid. • This is currently in heroic phase, uses on-site staff people. • This assumes there is an on-site staff person at the Gateway. • True for large, well-funded projects but maybe not true for others. • This has to be a potential success story: small colleges, MSIs, etc., need TeraGrid resources. • We think the Gateways effort should be expanded to include software support as well as integration. • Directly support common software base of many of the Gateways. • Respond to gateway requirements, bugs, feature requests with priority. • Provide depth of support for smaller gateways. • Portal hosting, custom development, training.

  26. A TeraGrid Science Gateway Software Center • The center would focus on a common (but not required) software stack for gateways. • Represents common practice and the “eigen” portal, at least for Java. • Possible future eigen-portals for Python, PHP, Ruby, etc, and linear combinations thereof. • Center’s board of directors would consist of current TG Gateway leadership and representatives from active gateway projects. • Those in charge now would still be in charge. • We would give them more power.

  27. How Is This Different from Now? • Current efforts focus on integration. • Two concerns: • How do we support smaller groups? • The Gateway bar is getting higher, not lower, as we think through the requirements. • How do we help bridge between campus Grids and the TeraGrid? • A Gateway SSP will support integration through both common and Gateway specific software. • General portal/portlet software • AND services (such as logging, auditing, accounting, shutdown) that all gateways need based on gateway requirements. • AND hosting services to help smaller groups • AND training on specific base software for new developers. • We are NOT the portal police • Existing gateways can maintain their own autonomous software bases. • Not everything goes in the gateway stack.

  28. Looking Forward • We obviously are positioning the OGCE project to be a Software Service Provider for the science gateways. • As we envision it, the Gateways SSP would • Develop portlets and services to support gateways generally. • “Tactical to strategic” approach as we ramp up. • Collaborate with large gateways (RENCI) on specific problems. • Package and integrate tools into a simple Gateway download. • Support these tools through help desks. • How does this compare to the NSF vision for SSPs?
