Abstract

MPI and PVM have been widely accepted for parallel programming and several implementations have been reported for clusters of UNIX workstations, supercomputers and parallel machines. In the recent past there has been an increasing use of MPI and PVM in clusters of personal computers running the Windows operating system. Traditionally, parallel programs have been developed in Fortran and C. However, the extraordinary success of the Java language has raised an impressive hype among the community of software programmers, in such a way that it seems quite promising that parallel programmers could also use Java in their applications. This can be assured if the communication libraries (PVM and MPI) could also provide a Java interface, thereby complementing the existing C and Fortran programming interfaces.
In this paper, we describe the implementation of Java interface for WMPI, a Windows-based implementations of MPI that have been developed and supported by our group. We show some details about the implementation, a MPI programming example using Java and we present some experimental results that compare the performance of Java WMPI, Java WPVM and the C programs counterparts.
