Talk Title: New Rules: Sustaining Performance Scaling in a Physical World

Abstract: As industry moves to increasingly small feature sizes, performance scaling will become increasingly dominated by the physics of the computing environment. Sustaining performance scaling will require understanding, characterizing, and collaboratively managing the multi-physics and multi-scale (nanoseconds to milliseconds) transient interactions between the delivery, dissipation, and removal (cooling) of power and their impact on system level performance. There are fundamental trade-offs to be made in processor design at the microarchitectural level between performance, energy/power, reliability, and packaging. In particular, these tradeoffs become increasingly pronounced with heterogeneity and diversity of application workloads. This talk will describe how interacting physical phenomena, e.g., thermal coupling, i) limits performance scaling, ii) drives application-driven microarchitecture-level tradeoffs, and iii) leads to operational principles for energy-efficient heterogeneous many core architectures. In particular, the talk will cover some exemplar implementations on modern integrated CPU-GPU architectures.

Biography: Sudhakar Yalamanchili earned his Ph.D. degree in Electrical and Computer Engineering from the University of Texas at Austin. Upon graduation, he joined Honeywell's Systems and Research Center in Minneapolis working on embedded multiprocessor architectures. He joined the ECE faculty at Georgia Tech in 1989 where he is now a Regents Professor and Joseph M. Pettit Professor of Computer Engineering. He is the author of two texts on VHDL-based simulation modeling and synthesis, and co-author with J. Duato and L. Ni, of Interconnection Networks: An Engineering Approach, Morgan Kaufman, 2003. His current research foci lie in addressing the software challenges of heterogeneous architectures and solutions to power and thermal issues in many core architectures and systems. Since 2003 he has been a Co-Director of the NSF Industry University Cooperative Research Center on Experimental Computer Systems at Georgia Tech. Dr. Yalamanchili regularly contributes professionally on editorial boards and program committees in high performance computing and computer architecture. He is a Fellow of the IEEE.
