Scalable system software: a component-based approach

The growth in computing resources at scientific computing centers has created new challenges for system software. These multi-teraflop systems often exceed the capabilities of the system software and require new approaches to accommodate these large processor counts. The costs associated with development and maintenance of this software are also significant impediments, which are compounded by a lack of interoperability because of site-specific enhancements. The Scalable System Software project seeks to address these issues through a component based approach to system software development. An overview of this design and the benefits of such an approach will be discussed in this paper.
