The fast growth of high bandwidth wide area networks has allowed the building of grids, which are constituted of PC clusters and/or parallel machines. Grids enable the design on new numerical simulation applications. For example, it is now feasible to couple several scientific codes to obtain a multi-physic application. In order to handle the complexity of such applicatio- ns, software component technology appears very appealing. However, most current software component models do not provide any support to transparently and efficiently embed parallel codes into components. This paper describes a first study of GridCCM, an extension to the CORBA Component Model to support parallel components. The feasibility of the model was evaluate thanks to the implementation of the model above two CCM prototypes. Preliminary performance results show that bandwidth is efficiently aggregated.
