Abstract
The paper begins by considering what a grid computing environment might be, why it is demanded and how the authors' HP spmd programming fits into this picture. We then review our HP Java environment as a contribution towards programming support for high-performance grid-enabled environments. Future grid computing systems will need to provide programming models. In a proper programming model for grid-enabled environments and applications, high performance on multi-processor systems is a critical issue. We describe the features of HP Java, including run-time communication library, compilation strategies and optimization schemes. Through experiments, we compare HP Java programs against FORTRAN and ordinary Java programs. We aim to demonstrate that HP Java can be used “anywhere”—not only for high-performance parallel computing, but also for grid-enabled applications.
