Pegasus

Pegasus (Planning for Execution in Grids) is a workflow mapping engine that automatically maps high-level workflow descriptions onto distributed resources. It takes a description of computational tasks to be performed and adds the necessary data transfers and data registration tasks (optionally). Pegasus uses the Condor DAGMan execution engine to execute on Condor pools, and clusters managed by PBS and LSF. Pegasus can optimize the workflow performance and reliability.
