INTEROPERABILITY OF GRID COMPONENT MODELS: GCM AND CCA CASE STUDY ∗

Abstract This paper presents a case study in the generic design of Grid component models. It defines a framework allowing two component systems, one running in a CCA environment, and another running in a Fractal environment, to interact as if they were elements of the same system. This work demonstrates the openness of both Fractal and CCA component models. It also gives a very generic and exhaustive overview of the interaction strategies that can be adopted to allow full integration of these two models, like strategies for reusing in Fractal single components from the CCA world and connecting a Fractal system to an already running CCA assembly. Finally, it presents the implementation and results of investigation of interoperability between two given component frameworks: MOCCA and ProActive. In generall, this paper presents the key concepts useful to make any two component models interoperate
