  1. Open Grid Computing Environments Marlon Pierce, Suresh Marru, Gregor von Laszewski

  2. IU: Marlon Pierce, Dennis Gannon, Suresh Marru RENCI: Gopi Kandaswamy RIT: Gregor von Laszewski SDSC: Nancy Wilkins-Diehr SDSU: Mary Thomas, Rob Edwards TACC: Maytal Dahan OGCE Principals

  3. Sections Project organization: code, build, demo. Workflow suite overview and demo. JavaScript COG demo Other good stuff Interactions Feel free to distract us. OGCE Present and Future Work

  4. Build and package Grid portal software. Portlets for GRAM, GridFTP, etc Provide programming libraries for building Grid clients. Java COG, GTLAB, JavaScript COG Build and package portal services GPIR Provide workflow tools: XRegistry, GFAC, XBaya What Does the OGCE Do?

  5. Browser Time…

  6. We have several substantial components to support, extend. Portal software Improvements to existing interfaces Sakai container integration GFAC, Workflow Suite Add eventing system for monitoring workflows, tracking provenance. Support for asynchronous workflows. Use TeraGrid community credentials Java COG abstractions Upgrades to the Condor and SRB support Information service providers (see next) Need new providers: Amazon S3, EC2 Future Work, Part 1

  7. Focused support for TeraGrid gateways. Logging, auditing, accounting services. Support, integration with TG information services See JP Navarro’s talk at GCE07 Engage other communities Web 2.0 tools for mashup gateway building Leverage social networking, bookmarking, start page tools JavaScript CoG Support for non-Java environments through the JS COG. Testing framework with NMI test bed, Jmeter. Future Work, Part 2

  8. OGCE Workflow Suite • Development Team: Srinath Perera, Chathura Herath, Gopi Kandaswamy, Satoshi Shirasuna • Generic Service Toolkit (Gfac) allows users to wrap any command line applications as web service. • XRegistry is an application service registry which allows users to register web service descriptions using GFAC portlet interface and access and invoke the services from XBaya toolkit and Gfac Portlet. • XBaya is an Java webstart application that can be used for composition, running and monitoring of workflows.

  9. Few Examples • LEAD: Linked Environment for Atmospheric Discovery • MotifNetwork: Genome-Wide Domain Analysis
