Connecting communities on the meta-scheduling level: The DGSI approach

The incompatibility on the meta-scheduling level proved to be a major hurdle for the coordinated cooperation of different Service Grids especially when focusing on the overall goal of better resource utilization. The D-Grid Scheduler Interoperability (DGSI)a is targeting these use cases with the conception and development of a standards-based interoperability layer for Grid level scheduling in Service Grids. By allowing the users of a community to distribute the workload among resources within the management domain of another community while keeping the individual, specialized scheduling solutions being run by the communities, it offers new perspectives for community collabora- tion, resource sharing, and efficient utilization.
