Design and implementation of secured information services for the ASCI grid

Information services are an integral part of the grid architecture. It is the foundation of how resources are defined and their state known. More importantly, the user of the Grid gets a perspective of what a grid looks like, how it performs and what capabilities it has from information services. The Accelerated Strategic Computing Initiative (ASCI) has designed and deployed a set of grid services within the context of the ASCI program. We deploy information services by augmenting the Globus toolkit in order to meet the unique aspects of the ASCI grid. We describe the decisions made and processes developed to run a grid information service in the ASCI grid.
