A PID-Controlled Power Manager for Energy Efficient Web Clusters

Abstract

Large data centers using high-end processors operating continuously around the clock are major energy consumers. Long periods of idling due to low workload will cause a waste in energy because the processors are active but not doing any useful work. A cluster of low-end embedded processors could continuously match its computational capacity with the… (More)
