A Comprehensive Guide to Measuring the Power and Energy of Modern Systems
Chapman & Hall/CRC Computational Science Series

This book presents methods and devices for measuring power and energy consumption on modern computer systems. It describes how power is consumed on a computer system, and how each component can be isolated to accurately measure its power consumption. The authors will include descriptions of commonly used methods for power measurement, as well as their respective advantages and disadvantages. Each chapter will also provide step-by-step examples that the readers can follow and replicate. A section on the history of power and energy issues for computing systems, and a survey of the latest publications on energy efficient computing will also be included, along with lab exercise examples.
