Java Users Discuss Research Issues at June Workshop

Over the past 2 1/2 years, researchers from eight CRPC institutions have been investigating the use of World Wide Web technology for computing, focusing on the role of Java in science and engineering simulation. The CRPC sponsored a Birds-of-a-Feather session at Supercomputing '96 in November and a workshop at Syracuse University in December to involve other members of the HPCC community in this research. This summer, a follow-up workshop was held to continue to identify critical issues in creating programming environments that have both attractive user interfaces and high-performance execution.

The June 21 Workshop on Java for Science and Engineering Computation was held in association with the ACM SIGPLAN Symposium on Principles and Practice of Parallel Programming (PPoPP) in Las Vegas. The workshop focused on obtaining a broad perspective on participant interests and views, as well as more technical discussions.

Co-chaired by CRPC researcher Geoffrey Fox of the Northeast Parallel Architectures Center (NPAC) and Wei Li of the University of Rochester, the workshop featured discussions on the issues of using Java in simulations where Fortran and C++ are now used. This included both classic Grand Challenge applications and libraries, and distributed simulation. Other topics included optimized Java native compilers for numerical kernels, interpreted Java "wrappers" for visualization, and research issues on the Java language, compilers, interpreters, and runtime systems.

In addition to Fox and Li, the program committee included CRPC researchers Marina Chen (Boston University), Ian Foster (Argonne National Laboratories), Dennis Gannon (Indiana University), and Joel Saltz (University of Maryland-College Park). Other members were Susan Flynn Hummel (IBM T. J. Watson Research) and Klaus Schauser (University of California-Santa Barbara).
