Open Grid Computing Environment Summary

This summary outlines the Open Grid Computing Environment (OGCE) initiatives led by Indiana University and its consortium partners, covering funding sources from NSF NMI and OCI. The report details software developments such as Java portlets, GridFTP, and GPIR, as well as future plans for tools like experiment builders and Web 2.0 services. Contributions from various institutions, including RENCI and SDSC, are highlighted, emphasizing collaborations in gateway development and metadata management. The focus is on building community support and enhancing grid computing capabilities.

  1. Open Grid Computing Environment Summary Marlon Pierce Indiana University

  2. 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

  3. 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

  4. 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.

  5. 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.
