Code coupling using Parallel CORBA objects

Abstract

This paper describes an approach for scientific code coupling using CORBA objects. Our approach is based on an extension of CORBA, called PaCO (Parallel CORBA Object), to support efficiently the encapsulation of parallel codes into distributed objects. With such extension, a parallel code can be seen as a collection of identical CORBA objects. Our extension to CORBA modifies only the Interface Definition Language (IDL) syntax by adding new language constructs. These new keywords allow the specification of several aspects associated with a collection of objects. We developed a new IDL compiler that generates stubs and skeletons to manage collections of objects transparently to the users. Parallel CORBA objects have been used within an industrial application from Aerospatiale Matra in the field of Electromagnetic simulation. The paper gives some performance results. © 2001 by Springer Science+Business Media New York.
