Energy efficiency is an important quality of computing systems. Researchers try to analyze, model, and predict the energy efficiency and power consumption of systems. Such research requires energy efficiency and power measurements, as well as measurement methodologies. Many such methodologies exist. However, they do not account for multiple load levels and workload combinations. In this paper, we introduce the SPEC power methodology and the tools implementing this methodology. We discuss the PTDaemon power measurement tool and the Chauffeur power benchmarking framework. We present the SPEC Server Efficiency Rating Tool (SERT), the workloads it contains and introduce the industry-standard compute efficiency benchmark SPECpower_ssj2008. Finally, we show some examples of how the SPEC power tools have been used in research so far.
