Autotuning has demonstrated the potential to improve portability between different HPC systems by automating tedious machine specific optimizations. In this talk, I will review some success stories of using auuto-tuning. I will also talk about the challenges facing scaling auto-tuning up to larger applications and systems. Finally, I will describe how auto-tuning can be used for tuning energy consumption in addition to speed.
Jeffrey K. Hollingsworth is a Professor 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.
Dr. Hollingsworth's research seeks to develop a unified framework to
understand the performance of large systems and focuses in performance
measurement and auto tuning. He is Editor in chief of the journal Parallel
Computing, was general chair of the SC12 conference, and is Chair of ACM
SIGHPC.
