Parallel Java: A Unified API for Shared Memory and Cluster Parallel Programming in 100% Java
Alan Kaminsky · 2007
Parallel Java is a parallel programming API whose goals are (1) to support both shared memory (thread-based) parallel programming and cluster (message-based) parallel programming in a single unified API, allowing one to write parallel programs combining both paradigms; (2) to provide the same capabilities as OpenMP and MPI in an object oriented, 100% Java API; and (3) to be easily deployed and run in a heterogeneous computing environment of single-core CPUs, multi-core CPUs, and clusters thereof. This paper describes parallel Java's features and architecture; compares and contrasts parallel Java to other Java-based parallel middleware libraries; and reports performance measurements of parallel Java programs.
