The power consumption of a large scale system ultimately limits its performance. Consuming less energy while preserving performance leads to better system utilization at scale. The is o-energy-efficiency model was proposed as a metric and methodology for explaining power and performance efficiency on scalable systems. For use in practice, we need to determine what parameters should be modified to maintain a desired efficiency. Unfortunately, without extension, the iso-energy-efficiency model cannot be used for this purpose. In this paper we extend the iso-energy-efficiency model to identify appropriate efficiency values for workload and power scaling on clusters. We propose the use of "correlation functions" to quantitatively explain the isolated and interacting effects of these two parameters for three representative applications: LINPACK, row-oriented matrix multiplication, and 3D Fourier transform. We show quantitatively that the iso-energy-efficiency model with correlation functions is effective at maintaining efficiency as system size scales.
