Computing Web portals have been used to provide user interfaces to the grid, and the architecture of these systems is beginning to support pluggable component services. The Open Grid Computing Environments Collaboratory led by Dr. Marlon Pierce, one of the PI's, provides a general architecture and several basic services for Grid Portals. We will develop several new portal capabilities following the general OGCE component model and will leverage OGCE compatible portal middleware such as GridPort. The Project Manager and visualization services described above will include a prominent portal interface component to group-based services. We will contribute all developed components back to the OGCE so that they may be shared with the Portal community. Examples of user interfaces supported by the portal will be future generations of the WEB-IS system, currently used to analyze mantle convection data and earthquake clusters.
