Titanium: A High-Performance Java Dialect
Source: University of California
Titanium is a language and system for high-performance parallel scientific computing. Titanium uses Java as its base, thereby leveraging the advantages of that language and allowing programmers to focus attention on parallel computing issues. The main additions to Java are immutable classes, multidimensional arrays, an explicitly parallel SPMD model of computation with a global address space, and zone-based memory management. This paper discusses these features and design approach, and reports progress on the development of Titanium, including the current driving application: a three-dimensional adaptive mesh refinement parallel Poisson solver.
