Abstract

Java RMI provides an elegant and powerful model for invoking member functions on objects that exist in remote address spaces. Unfortunately, it is a Java-to-Java communication model, and in manyofthe scienti#c applications we would likeJava objects to interact with modules written in C++ or Fortran. This paper explores the design of RMI and extracts a subset of the RMI object model that is compatible with C++ and HPC++ remote object semantics. This RMI subset has been implemented to run over the Nexus runtime system and is being used as part of the LSA distributed linear system analyzer project. 1 Introduction Many high performance computing applications in the future will be designed and built as distributed systems based on an object component architecture. While some of the components in these systems will be built as Java clients and servers, many others will be built using Fortran and C++. In one such system, the Linear System Analyzer #LSA# #7#, about 22# of the source is...
