“…Its strength is to offer the same interface to very different networks. Such platform is being used as a runtime for code coupling applications based on the concept of parallel CORBA objects [18,6] for which there is a need to simultaneously use a middleware (CORBA) and a runtime (MPI). …”

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.

“…The specification does not deal with dynamic selection of resources for parallel computing. The PaCO [35,36] and PaCO þ þ [19,18] systems from the PARIS project in France are implemented within the CORBA [17] framework to encapsulate MPI applications in RPC systems. The data distribution and redistribution mechanisms in PaCO are much more robust than in GrADSolve and support invocation of remote parallel applications either from sequential or parallel client programs.…”

“…Though there are a large number of RPC systems that support remote invocation of parallel applications [15,16,22,29,35,37,38], the selection of resources for the execution of parallel applications in these systems does not take into account the dynamic load aspects that are associated with Computational Grids. Some of the parallel RPC systems [8,18,21,22,26,[28][29][30]35] are mainly concerned with providing robust and efficient interfaces for the service providers to integrate their parallel applications into the systems, and for the end users to remotely use these parallel services.…”

Although some existing Remote Procedure Call (RPC) systems provide support for remote invocation of parallel applications, these RPC systems lack powerful scheduling methodologies for the dynamic selection of resources for the execution of parallel applications. Some RPC systems support parallel execution of software routines with simple modes of parallelism. Some RPC systems statically choose the configuration of resources for parallel execution even before the parallel routines are invoked remotely by the end user. These policies of the existing systems prevent them from being used for remotely solving computationally intensive parallel applications over dynamic computational Grid environments. In this paper, we discuss a RPC system called GrADSolve that supports execution of parallel applications over Grid resources. In GrADSolve, the resources used for the execution of parallel application are chosen dynamically based on the load characteristics of the resources and the characteristics of the application. Application-level scheduling is employed for taking into account both the application and resource properties. GrADSolve also stages the user's data to the end resources based on the data distribution used by the end application. Finally, GrADSolve allows the users to store execution traces for problem solving and use the traces for subsequent solutions. Experiments are presented to prove that GrADSolve's data staging mechanisms can significantly reduce the overhead associated with data movement in current RPC systems. Results are also presented to demonstrate the usefulness of utilizing the execution traces maintained by GrADSolve for problem solving. r
