Pegasus: Mapping Scientific Workflows onto the Grid

In this paper we describe the Pegasus system that can map complex workflows onto the Grid. takes an abstract description of a workflow and finds the appropriate data and Grid resources to execute the workflow. Pegasus is being released as part of the GriPhyN Virtual Data Toolkit and has been used in a variety of applications ranging from astronomy, biology, gravitational-wave science, and high-energy physics.
