NSF Funds Rev Up Pegasus Grid Workflow Engine

September 20, 2007

Ewa Deelman's ISI team will use its share of a 3-year $1.7 million NSF Office of Cyberinfrastructure grant to improve the usability and breadth of support of their automated task organization and execution system.

"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," said 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 different people," explained Deelman. "It compiles not only software and data, but also the expertise of the people who developed the software."
