Portable Parallel CORBA Objects: an Approach to Combine Parallel and Distributed Programming for Grid Computing

With the availability of Computational Grids, new kinds of applications that will soon emerge will raise the problem of how to program them on such computing systems. In this paper, we advocate a programming model that is based on a combination of parallel and distributed programming models. Compared to previous approaches, this work aims at bringing SPMD programming into CORBA. For example, we want to interconnect two MPI codes by CORBA without modifying MPI or CORBA. We show that such an approach does not entail any loss of performance compared to previous approaches that required modification to the CORBA standard
