Matching jobs with resources: an application-driven approach

We present a distributed matchmaking methodology based on a two-level (low-level and application-level) benchmarking, that allows the specification of both syntactic and performance requirements. In particular, we point out how the use of application-level benchmarks gives a more accurate characterization of resources, so enabling a better exploitation of Grid power. The proposed methodology relies on the use of standard description languages at both application and resource sides, to foster interoperability. Moreover, the proposed tool is independent of the underlying middleware, and its distributed structure supports scalability.
