2003 NEWS AND HIGHLIGHTS
07.09.03 - NASA Grid Technology Shines at GGF8
The NAS Division's reputation for spearheading grid technologies was reinforced at the recent Global Grid Forum 8 (GGF8) in Seattle, when a team of NASA's Information Power Grid (IPG) scientists hosted workshops and showcased IPG technologies. Several NAS presentations resulted in proposals for collaboration, requests for software, and invitations for increased participation in research and working groups.
Among the presentations by grid experts around the world was NAS scientist Rebekah Lepro's overview of Cardea, a dynamic authorization system developed for the IPG. Rebekah's work on the Cardea system is a perfect example of the kind of work we are doing for the IPG -- Identifying problems with existing grid middleware and developing solutions to fill the gaps, said NAS IPG lead, Tony Lisotta. From what I heard from other participants at GGF, her work is definitely ahead of the curve in this area. As a result of the presentation, Lepro was urged to participate more heavily in the forums' research groups and now plans further collaboration with the University of Pittsburgh.
Cardea, named after the goddess of thresholds and door pivots, began as an authorization, allocation, and auditing project, and evolved into a system that allows users access to grid resources without needing an account. NAS now has a prototype available for demonstration.
NAS scientists Warren Smith and Paul Kolano were among the presenters at a workshop on Tools for Grid Management, chaired by NAS senior scientist Judith Utley. Smith's overview of the Control and Observation in Distributed Environments (CODE) software resulted in a software request from a European supercomputing center.
Smith is a regular contributor to the Open Grid Services Architecture document, a blueprint for grid services developers, and is currently working with several other GGF members to form a Grid Event Service working group to define standards relating to distributed event services.
Kolano also received software requests for his IPG Portability Manager, a software tool that automatically resolves issues in executing applications on grid resources. Kolano described the Portability Manager in his presentation Automatically Establishing the Execution Environment for User Applications, and received inquiries about further collaboration from major national supercomputing centers.
Other NAS participation at GGF8 included a full-day workshop on Grid Applications and Programming Tools organized by NAS senior scientists Tom Hinke and Bob Hood. Hinke's co-authored paper on data mining experiments was nominated at GGF8 for inclusion in a special issue of the Journal of Grid Computing. The paper, Enhanced Product Generation at NASA Data Centers Through Grid Technology, by B.R. Barkstom, T.H. Hinke, S. Gavali and W. J. Seufzer is part of a collaborative project with Langley Research Center, and will be finalized during the next couple of months.
