Ensemble Manager
Current workflow planners allow only sequential or uncoordinated planning and execution of a single workflow. The Ensemble Manager coordinates and efficiently handles planning and executing 100’s to 1000’s of workflows simultaneously on the Grid.
The EM provides several operations to submit, plan, execute and monitor several workflows simultaneously. The workflows can be planned by Pegasus or sent directly to DAGMan. The workflows bring along with them all the context, so for example a DAX will bring with it a Transformation Catalog, Site Catalog, and Properties File.
