An Incremental Methodology for Energy Measurement and Modeling

This paper presents an empirical approach to measuring and modeling the energy consumption of multicore processors.The modeling approach allows us to find a breakdown of the energy consumption among a set of key hardware components, also called HW nodes. We explicitly model the front-end and the back-end in terms of the number of instructions executed. We also model the L1, L2 and L3 caches. Furthermore, we explicitly model the static and dynamic energy consumed by the the uncore and core components. From a software perspective, our methodology allows us to correlate energy to the executed code, which helps find opportunities for code optimization and tuning.
