Granular CPU power measurement for SMP clusters

One of the key challenges in optimizing CPU power consumption at the program level is the difficulty of precisely measuring the power consumption of the CPU (as distinct from other system components) during the various phases of a program's execution. This paper presents a scalable CPU power measurement framework with its associated reporting and data acquisition components that can be used to accurately measure program-related CPU power consumption on symmetric multiprocessor (SMP) cluster systems.
