Towards Sustainable Computing: Innovative Design and Management Strategies across the Computing Stack

Ayse Kivilcim Coskun

Assistant Professor of Electrical and Computer Engineering
Hariri Institute Junior Faculty Fellow

Abstract: Energy efficiency is a central issue in all computing domains. In data centers, operational and cooling costs impose significant sustainability challenges. In tandem, future processors are expected to run complex, highly performance demanding workloads, making the well-studied energy management policies inadequate. High power densities also increase the on-chip temperatures and thermal variations, both of which degrade system reliability and add to the system design complexity. Achieving orders of magnitude of energy efficiency improvements requires novel system and software design approaches coupled with dynamic techniques that recognize the hardware-software characteristics and understand the complex interplay among performance, energy, and temperature. This talk will discuss two closely-tied research thrusts: (1) designing 3D stacked architectures and the necessary runtime management strategies for them as means of improving processor energy efficiency; and (2) developing workload management and power capping methods in data centers to reduce the overall energy cost of computing.

Bio: Ayse Coskun was one of the first class of Junior Faculty Fellows for the Hariri Institute. She received her Ph.D. from University of California, San Diego in 2009. Her research interests cover temperature and energy management for computing hardware, 3D stacked architecture in chip design, and reliability analysis and optimization. Professor Coskun’s honors include the NSF CAREER Award (2012) and the Best Paper Award from the High Performance Embedded Computing (HPEC) Workshop (2011).
