Deploying CORBA Components on a Computational Grid: General Principles and Early Experiments Using the Globus Toolkit

The deployment of high bandwidth wide-area networks has led computational grids to offer a very powerful computing resource. In particular, this inherently distributed resource is well-suited for multiphysics applications. To face the complexity of such applications, the software component technology appears to be a very adequate programming model. However, to take advantage of the computational power of grids, component-based applications should be automatically deployed in computational grids. Based on the CORBA component specifications for the deployment of components, which seem to currently be the most complete, this paper proposes a detailed process for component deployment in computational grids. It also reports on early experiments on deploying CORBA components in a computational grid using the Globus Toolkit 2.4
