Biography:
Jeffrey K. Hollingsworth is a Professor and Associate Chair of the Computer Science Department at the University of Maryland, College Park. He also has an appointment in the University of Maryland Institute for Advanced Computer Studies and the Electrical and Computer Engineering Department. He received his PhD and MS degrees in computer sciences from the University of Wisconsin. He received a B.S. in Electrical Engineering from the University of California at Berkeley. He joined the faculty of the University of Maryland in 1994.
Dr. Hollingsworth’s research seeks to develop a unified framework to understand and optimize the performance of large systems and focuses in several areas. First, he developed new approach, called dynamic instrumentation, to permit the efficient measurement of large parallel applications. Second, he has developed an auto-tuning framework called Active Harmony that can be used to tune kernels, libraries, or full applications. Third, he is investigating the interactions between different layers of software and hardware to understand how they influence performance and how to map data between these layers of abstraction.
He has served on the board of directors of the Computing Research Association. He is Editor in chief of the journal Parallel Computing, and is the general chair of the SC12 conference (the largest HPC conference in the world with over 10,000 attendees).
