ET Accomplishments Technology: This work has impact on the Science portals, EOT and the Access Grid. There are two technology components; a general Collaborative portal framework (Garnet) for both computing and education applications and a Science portal Gateway. Gateway is built on earlier technology (WebFlow) developed in the Alliance and applied in an early nanomaterials PSE. It is currently being used in structural mechanics problems with NCSA scientists working in the DoD PET program. Gateway uses CORBA and Kerberos security and supports most functionalities identified in the Grid Forum Computing Environment (GCE) working group. It supports XML specified wrapping of applications implemented as middle tier proxies linking to Globus or standard schedulers on back-end resources. Gateway is used for "production" work while the very recent Garnet system is tested and refined. Garnet is built around XML messages with synchronous and asynchronous collaboration implemented with a publish/subscribe (JMS currently) mechanism. The XML-based message service spans several uses -- we see it as a candidate for a Grid Event and Message Service. It supports functionality of JMS (Java Message Service), shared event collaboration and events needed in computing portals. Garnet supports sharing of objects and over this summer will be integrated with the Access Grid. It allows both handheld and desktop devices to join in collaborative sessions as part of support of universal access. It is designed to provide a modular web collaboration service linking to other computing or education portals (e.g. Gateway or WebCT), visualization systems etc. Over the summer, we are testing the prototype (released in May) and especially focus on the XML event system linking both to an Enterprise Javabean middle tier and an Oracle backend.Garnet is designed to support either desktop or handheld clients and we have developed use of PDA's to control visualization on large screens. One innovative feature of our approach is support of shared SVG (Scalable Vector Graphics). Garnet has several features in common with JXTA and integration of our ideas with those of Peer-to-Peer networking sdeems very promising. We expect this project will become closer integrated with the Alliance and especially applications as it is relocated (as of July 2001) to Bloomington, Indiana and collaborates closely with existing portal group led by Gannon. At Indiana Fox leading the Pervasive Technology Laboratory for Community Grid computing; the NCSA work will leverage the $1M per year Lilly grant providing the core funding of this laboratory. Outreach: The collaboration technology is core to work with Indian Nation on building collaborative environments. We attended two multi-day meetings organized by the American Indian Higher Education Consortium AIHEC or rather their High technology Committee led by Tom Davis and Jack Briggs. We developed the concept of a "Digital Indigenous Homeland" designed to allow members of tribes participate in the modern economy from their homelands. We are preparing follow-on proposals We are working with structural mechanics group at NCSA with Gateway. We are working with the Earthquake forecasting community (GEM for General Earthquake Model and the NSF STC Center SCEC) on many computing and collaboration technologies. Leverage Work funded by DoD High Performance Computing Modernization Office in collaboration and computational portals. Uses subsystems from Argonee/NCSA (Access Grid) and Anabas (Shared Display) At Indiana Fox leading the Pervasive Technology Laboratory for Community Grid computing; the NCSA work will leverage the $1M per year Lilly grant providing the core funding of this laboratory.
