Title:		"Towards Energy Efficient Database Computing"

Date:		Monday, 20 September 2010

Time:		4:00pm - 5:00pm

Venue:		Lecture Theater F (near lifts 25/26), HKUSt

Abstract:

Rising energy costs in large data centers drive the agenda for energy
efficient computing. Towards this goal, it is critical to understand the
interplay between energy consumption and performance in database
servers. The first part of the talk will focus on quantifying the role
of database software in the overall energy efficiency of a server. Then,
I will present the results of a recent study (SIGMOD'10) on the power
usage profiles of database operators and I will discuss the effect of
different configuration parameters on the energy efficiency of a
database system. The last part of the talk will cover ongoing work in
improving the energy efficiency of a cluster dedicated to an analytic
parallel database system.
