Performance engineers are beginning to explore software-level optimisation as a means to reduce the energy consumed when running their codes. This paper presents POSE, a mathematical and visual modelling tool which highlights the relationship between runtime and power consumption. POSE allows developers to assess whether power optimisation is worth pursuing for their codes. We demonstrate POSE by...
With recognizing power as a first-class citizen in the HPC community and the growth of software running on battery-driven devices, the need to evaluate software design based on the combined effects of energy and performance has become eminent. Despite of the numerous metrics to evaluate software performance, the study on how to evaluate software energy efficiency is still in its early stage. In this...
