Fishbowl teleseminar: Algorithmic Challenges for Greening Data Centers

March 20, 2012 @ 3:30 pm - 5:15 pm

Prof. Adam Wierman,
Assistant Professor
Dept. of Computing and Mathematical Sciences


Given the significant energy consumption of data centers, improving their energy efficiency is an important social problem.  However, energy efficiency is necessary but not sufficient for  sustainability, which demands reduced usage of energy from fossil fuels. In this talk, I will describe some recent work highlighting the algorithmic challenges associated with “greening” data centers. We will focus on two applications — (i) dynamic resizing within a data center and (ii) geographical load balancing across an Internet-scale system. In both contexts I will present our new algorithms, which provide significantly improved guarantees when compared with the “standard” approaches using Receding Horizon Control. Additionally, if time allows, I will briefly discuss the our recent progress toward the implementation and evaluation of these algorithms in industry data centers.
