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

4. What Does the OGCE Do? 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

5. Browser Time…

6. Future Work, Part 1
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

7. Future Work, Part 2 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.

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.
