Pegasus Soars on NSF Wings

Viterbi Team to Improve Automated Workflow System

Ewa Deelman’s Information Sciences Institute (ISI) team will use its share of a three-year, $1.7 million National Science Foundation (NSF) grant to improve the usability and breadth of support of its automated task organization and execution system. The grant was issued by NSF’s Office of Cyberinfrastructure.

“We’re now in a position to work with more communities and more users, including those using Open Science Grid and TeraGrid, to bring Pegasus technologies to their computing work,” says Deelman.

Pegasus allows researchers to translate complex computational tasks into workflows that link and manage ensembles of dependent tasks and related data files.

“Pegasus automatically chains dependent tasks together, so that a single scientist can complete complex computations that once required many people,” explains Deelman. “It compiles not only software and data, but also the expertise of the people who developed the software.”
