Compiling Explicitly Parallel Programs

Abstract : This report documents the Titanium language and system for high-performance parallel scientific computing. Titanium uses Java as its base, thereby leveraging the advantages of that language and allowing the focus on parallel computing issues. The main additions to Java are immutable classes, multi-dimensional arrays, an explicitly parallel SPMD model of computation with a global address space, and zone-based memory management. The features and design approach of Titanium are discussed, including an application: a three-dimensional adaptive mesh refinement parallel Poisson solver.
