A study of the effectiveness of CPU consolidation in a virtualized multi-core server system
Inkwon Hwang, Timothy Kam, Massoud Pedram · 2012
The focus of this paper is on dynamic power management in virtualized multi-core server systems. The paper starts by analyzing the effect of virtualization and CPU consolidation on power dissipation and performance (latency) of such systems, and concludes by presenting two new CPU consolidation algorithms for multi-core servers. The paper also reports an extensive set of experimental results founded on a realistic multi-core server system setup and well-developed benchmarks, i.e., SPEC2K and SPECWeb2009 and obtained through hardware measurements.
