Experimentations With CoRDAGe, A Generic Service For Co-Deploying and Re-Deploying Applications On Grids

Computer grids are made of thousands of heterogeneous physical resources that belong to different administration domains. This makes the use of the grid very complex. In this paper, we focus on deploying distributed applications at a large scale. As the application requirements may often not be anticipated, dynamic re-deployment is needed; if various applications have to co-operate within a workflow, they should also be co-deployed in a consistent way. In a previous paper, we have described the CORDAGE deployment model and its architecture. It meets the three properties of transparency, versatility, and neutrality. We report in this paper on its application to a real co-deployment over the GRID'5000 experimental platform, using different configurations, including multiple clients, multiple applications and multiple grid sites
