Title: “Energy-Efficient Computing: The Role of Parallelism”
Over recent years, parallel computing has emerged in mobile devices, mainstream computers, and high-end servers as a means to reach aggressive performance targets while also maintaining acceptable power and thermal characteristics. As a result, current computer systems design — both at the software and hardware level — revolves around effective management of many different shared resources, such as processor cores, memory hierarchy capacity and bandwidth, or an overall power budget. This talk will discuss my group’s research in power-aware computing across several scales, particularly highlighting examples where effective management of shared resources leads to power, performance or parallelism improvements.
Margaret Martonosi is Professor of Computer Science at Princeton University, where she has been on the faculty since 1994. She also holds an affiliated faculty appointment in Princeton EE. 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 six granted US patents. Martonosi is a fellow of both IEEE and ACM. In 2010, she received Princeton University’s Graduate Mentoring Award.
