%T A Comparison of High Performance, Parallel Computing Java Packages %A Nan C. Schaller, Sidney W. Marshall, Yu\-Fong Cho %E Jan F. Broenink, Gerald H. Hilderink %B Communicating Process Architectures 2003 %X The high\-performance computing community has developed numerous Java packages that support parallel and distributed computing. Most of these packages are designed for the typical parallel message passing and shared memory architectural paradigms. This paper presents the results of a recent study that included a web search for such packages, describes the paradigms implemented in them, and evaluates their performance on a parallel, 4\-processor SMP machine using three benchmark programs that represent a mix of typical parallel applications, chosen from The Java Grande Benchmark Suite. A brief description of each package and a discussion its ease of installation and use are also provided.
