Organization of the Thesis

The outline of this thesis is as follows. Chapter 2 provides a general overview of the Java Grande Forum, its activities, and processes. The Java Grande Forum is a group looking at general issues for large-scale computing in Java. We also discuss Java for scientific parallel programming issues and look at work related to Java Grande in Chapter 2. Chapter 3 introduce the design of our HPJava framework and its core features. HPJava is a programming language extended from Java to support SPMD parallel programming style. In Chapter 4, we discuss the design of the mpiJava API, an object-oriented Java interface to MPI, and the issues associated with its development. Chapter 5 describes use of the Java object serialization model for marshalling communication data in Java bindings of MPI. Chapter 6 presents applications and analyzes the performance of Ising model simulation implemented using mpiJava, and compared with Fortran and C versions. Finally, Chapter 7 contains conclusion and the directions for future work.
