Abstract
 

The power efficiency of PC-class and server systems has been on a steady decline over the past few years, due to a combination of fabrication challenges, focus on MHz and instruction-level parallelism, and overall lack of attention to energy savings outside of the portable market.

In this talk I will discuss the increasing relevancy of power and cooling costs on large-scale server farms, as well as the adequacy of different power management techniques for such a platform.

 
 
 
Bio
 

Andre Barroso is a Principal Engineer at Google, where he currently leads the Platforms group. At Google he has focused on improving the efficiency and robustness of Google's Web services, including the development of load balancers and RPC networking libraries, optimization of the index-serving code base, and the design of Google's computing platform.

Prior to Google he was a member of the Research Staff at Compaq and Digital Equipment Corporations, where his group published extensively on processor and memory system design for database and web server workloads. While at Compaq, he co-architected and designed the Piranha system, a scalable shared-memory multiprocessor based on single-chip multiprocessing.

Luiz holds a Ph.D. in Computer Engineering from USC and M.Sc./B.Sc. degrees in Electrical Engineering from PUC-Rio, Brazil.
