Integrated MPI and Java for Scientific and Commercial Parallel and Distributed Applications

70 Integrated MPI and Java for Scientific and Commercial Parallel and Distributed Applications--MPI Software Technology, Inc., 1 Research Blvd. Suite 201, Starkville, MS 39759-9741; (601) 320-4300 Mr. George Crawford, Principal Investigator Dr. Anthony Skiellum, Business Official DOE Grant No. DE-FG02-97ER82434 Amount: $75,000 A Department of Energy mission is to develop advanced software tools and systems for effective utilization with high-performance computer systems. This project will design an efficient, portable, and scalable Application Programming Interface (API) and runtime environment for high-performance computing through the integration of the Message-Passing Interface (MPI) standard specification and concepts with Java. Various approaches to integrating the MPI programming model and the Java model will be undertaken. Specifically, object-oriented design issues will be investigated, as will the appropriateness of MPI in the several Java programming sub-models with evaluation keyed to potential applications, such as web servers. Phase I entails the design of an object-oriented interface for Java, design of competing efficient runtime environments for MPI Java applications, and evaluations of these runtime environments using appropriate performance metrics. A market study into the commercial and governmental opportunities for early and long-term adoption of this technology will be conducted. Phase II will entail the development of prototypes that demonstrate Phase I designs, performance and other metrics-based analysis of these prototypes, as well as cooperation with early adopters in government and industry. Commercial Applications and Other Benefits as described by the awardee: If successful, this research would provide a new, scalable programming model to Java programmers, and bring Java to users of high performance programming systems, where MPI is currently common. Software developers who currently use Java and want to access scalability will benefit (web servers, scalable Internet services, defense applications).
