5:00 PM – Salvatori Auditorium (SAL-101) Reception

Over recent decades, power and energy issues have emerged as a fundamental challenge to computer systems design at all scales. In mobile computing, achieving high performance capabilities at low energy for long battery lifetimes is a central goal. At the data center level, power and thermal constraints are fundamental limiters in the scale, operating cost, and environmental impact of internet services and the data centers they run on.

This talk will touch on my group’s research in power-aware computing across these scales, including both hardware and software techniques for managing power-performance tradeoffs.

Margaret Martonosi is currently Professor of Electrical Engineering at Princeton University, where she has been on the faculty since 1994. She also holds an affiliated faculty appointment in Princeton CS. Martonosi’s research interests are in computer architecture and the hardware/software interface, with particular focus on power-efficient systems and mobile computing.

In the field of processor architecture, she has done extensive work on power modeling and management and on memory hierarchy performance and energy. This has included the development of the Wattch power modeling tool, the first architecture level power modeling infrastructure for superscalar processors. In the field of mobile computing and sensor networks, Martonosi led the Princeton ZebraNet project, which included two real-world deployments of tracking collars on Zebras in Central Kenya. In addition to numerous publications, she has co-authored a technical reference book on Power-Aware Computing and five granted US patents. Martonosi is a fellow of both IEEE and ACM.
