“Pegasus at the Edge: Supporting Edge-to-Cloud Scientific Workflows”

Tuesday 14 February, 2.05pm – 2.40pm

Abstract

Scientific workflows are now a common tool used by domain scientists in a number of disciplines. They are appealing because they enable users to think at a high level of abstraction, composing complex applications from individual application components. This talk focuses on the Pegasus workflow management system, which automates the process of executing workflows on modern cyberinfrastructure. It takes high-level, resource-independent descriptions and maps them onto the available heterogeneous resources: campus clusters, high-performance computing resources, high-throughput resources, clouds, and now the edge. This talk will describe the key concepts used in the Pegasus WMS and how they allowed the system to incorporate the edge as a computing platform for scientific workflows.

Bio

Ewa Deelman received her PhD in Computer Science from the Rensselaer Polytechnic Institute in 1998. Following a postdoc at the UCLA Computer Science Department she joined the University of Southern California’s Information Sciences Institute (ISI) in 2000, where she is serving as a Research Director and is leading the Science Automation Technologies group. She is also a Research Professor at the USC Computer Science Department and an AAAS and IEEE Fellow.

The USC/ISI Science Automation Technologies group explores the interplay between automation and the management of scientific workflows that include resource provisioning and data management. Dr. Deelman pioneered workflow planning for computations executing in distributed environments. Her group has led the design and development of the Pegasus Workflow Management software and conducts research in job scheduling and resource provisioning in distributed systems, workflow performance modeling, provenance capture, and the use of cloud platforms for science.

Dr. Deelman is the founder of the annual Workshop on Workflows in Support of Large-Scale Science (WORKS), which is held in conjunction with the SC conference. In 2015, Dr. Deelman received the HPDC Achievement Award for her contributions to the area of scientific workflows and in 2022 she received the Euro-Par Achievement Award for her outstanding contributions to parallel computing.
