Efficiency of Distributed Parallel Processing Using Java RMI, Sockets, and CORBA

Overview

Software development is proceeding at a remarkable rate. Many new tools are available to the researcher in parallel and distributed processing. These tools include PVM, MPI, and Java. But, recently, a more general tool, Common Object Request Broker Architecture, (CORBA) has appeared. Since it allows a general view of remote object invocation, and hence another look at distributed parallel programming, CORBA is enjoying considerable attention. This paper considers CORBA and Java, focusing on the overhead and efficiency of Java sockets, Java RMI, and Java's interface to CORBA.
