Abstract : The objective of the High Performance Distributed Systems Architecture (HPDSA) project are to integrate very high bandwidth networks with heterogeneous computer architectures (including parallel and specialized processors) and support multiple programming models with this system. The driving forces for this project are user demands for high- performance computing coupled with the availability of gigabit and high bandwidth networking. Command and control applications are increasingly requiring the capabilities of both specialized processors and supercomputer-class machines. These resources are often concentrated at computer centers while the data sources and users of these systems are geographically distributed. By linking users, data sources, and systems together with high-speed networks and distributed operating systems, we can substantially improve the quality of command and control information and provide that information to more people. A high-performance distributed operating system must satisfy a number of design goals to accomplish our architectural objectives. Foremost, it must be capable of accommodating a wide variety of computers, networks and programming languages.
