Abstract

Dynamic parallel applications such as CFD-OG impose a new problem for distributed processing because of their dynamic resource requirements at run-time. These applications are difficult to adapt in the current distributed processing model (such as the Grid) due to a lack of interface for them to directly communicate with the runtime system and the delay of resource allocation. In this paper, we propose a novel mechanism, the Application Agent (AA) embedded between an application and the underlying conventional Grid middleware to support the dynamic resource requests on the fly. We introduce AA’s dynamic process management functionality and its resource buffer policies which efficiently store resources in advance to maintain the execution performance of the application. To this end, we introduce the implementation of AA.
