Funding and Participants

• NSF NMI: 2003-2007• NSF OCI SDCI: 2007-2010• Current consortium:

– Indiana University: Marlon Pierce, Dennis Gannon– RENCI: Gopi Kandaswami– Rochester: Gregor von Laszewski– SDSC: Nancy Wilkins-Diehr– SDSU: Mary Thomas, Rob Edwards– TACC: Maytal Dahan

OGCE Software• Portlets: pluggable server-side Java components

– Now: GridFTP, GRAM, GPIR, Condor, Condor-G, Proxy Management

– SC07: Queue Prediction, PURSE, Xbaya workflow, GFAC Portlets

– Future: Experiment Builder• Supported Portlet Containers: GridSphere, Sakai

– Sakai 2.4 supports portlets via OGCE 1 funding• Web services

– Now: GPIR, CFT (deprecated)– SC07: GFAC (Application Wrapping), XRegistry– Future: Metadata catalog

OGCE Software, Continued• Grid Client Libraries

– Now: Java COG Kit and Abstraction Layer– SC07: Grid Tag Libraries and Beans (GTLAB)

• JSF XML libraries built with the COG– Future: JavaScript Grid libraries and related Web 2.0

services. Develop alternative (PHP, RoR) Web developer libraries for these.

• Gateway support software (future)– Auditing, logging, and reporting services

• Build process– SC07: Streamlined, Maven 2-based – Future: Maven 2 component-based.

• Build your own download, just get the pieces that you want.

Community Support• We are also interested in directly helping other

funded gateway projects.– Ex: We’ve worked with the CIMA project to build portlets and

integrate authorization.

• In addition to the OGCE, IU’s TeraGrid team is refocusing on Gateway development. – Dr. Sangmi Lee Pallickara (LEAD) and Dr. Yu (Marie) Ma

(CIMA) are on this team.– They both have extensive experience with data services and

metadata management.

• We are very interested in collaborating with data grid groups to build portal interfaces and services.
