Abstract

In this chapter we describe an end-to-end workflow management system that enables scientists to describe their large-scale analysis in abstract terms, then maps and executes the workflows in an efficient and reliable manner on distributed resources. We describe Pegasus and DAGMan and various workflow restructuring and optimizations they perform and demonstrate the scalability and reliability of the approach using applications from astronomy, gravitational-wave physics, and earthquake science.
