Scheduling Workflow Applications in Image-guided Surgery

This paper describes new strategies for scheduling and executing workflow applications on Grid resources using the Unifying Infrastructure in Image-guided Surgery (UIIS). Workflow scheduling is based on heuristic scheduling strategies that use combined computational and memory hierarchy application component performance models. The workflow is executed using a novel strategy to bind and launch the application onto heterogeneous resources. We apply these strategies in the context of launching image-guided surgery, a Bio-imaging workflow application, onto the Grid.
