Communication Performance of Java-Based Parallel Virtual Machines

Message passing libraries such as Parallel Virtual Machine PVM and Message Passing Interface MPI provide a common Application Programming Interface API to implement parallel programs across multiple computers. Such libraries provide a means to program a collection of normally independent computers to work cooperatively on a single computation. However, for programs written in C and Fortran these collections of machines may provide a heterogenous set of computer architectures, requiring a di erent executable for each type of architecture. The Java language o ers a potentially machine-independent method of distributing the same code to perform the computations on di erent computer architectures. The communication performance between processors running Java programs is a crucial issue for this type of application. This paper compares the performance between tradition PVM implemented in C code, Java code interfaced to the traditional PVM libraries JavaPVM, and Java code that perfo...
