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

12:00 AM - 11:15 AM on Friday, November 1, 2013
Location: Torg 2150

by Dr. Ayse Coskun, Boston University

Abstract:
image 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 novel 3D stacked architectures and the necessary runtime management strategies for improving processor energy efficiency; and (2) developing workload management and power regulation methods in data centers to reduce the overall energy cost of computing.
