Methodology of measurement for energy consumption of applications

Résumé

For IT systems, energy awareness can be improved in two ways, (i) in a static or (ii) in a dynamic way. The first way leads to building energy efficient hardware that runs fast and consumes only a few watts. The second way consists of reacting to instantaneous power consumption, and of taking decisions that will reduce this consumption. In order to take decisions, it is necessary to have a precise view of the power consumption of each element of an IT system. Nowadays, it is only possible to measure power at the outlet level, or - with larger efforts - a the hardware component level. It is still difficult to estimate the power consumption of single applications running on a computer. This work aims at evaluating the power consumption of single applications using indirect measurements. We describe a methodology for predicting the power consumption of a PC depending on performance counters, and then use these counters to predict the power consumption of a single process.
