Pegasus is an open-source workflow management system.[1][2][3] It provides the necessary abstractions for scientists to create scientific workflows[4] and allows for transparent execution of these workflows on a range of computing platforms including high performance computing clusters, clouds, and national cyberinfrastructure.[5][6] In Pegasus, workflows are described abstractly as directed acyclic graphs (DAGs) using a provided API for Jupyter Notebooks, Python, R, or Java.[7] During execution, Pegasus translates the constructed abstract workflow into an executable workflow[8][9] which is executed and managed by HTCondor.[10][11]

Pegasus is being used in a number of different disciplines including astronomy, gravitational-wave physics, bioinformatics, earthquake engineering, and helioseismology.[12] Notably, the LIGO Scientific Collaboration has used it to directly detect a gravitational wave for the first time.[8][13][14]

Area of applications

Application examples:[5][6]

History

The development of Pegasus started in 2001.
