Power Management from Handhelds to DataCenters: Chasing the Next 10X Improvements

Опубликовано 7 сентября 2016, 16:28

Energy and power are increasingly becoming critical challenges in the design of future computing systems. The SmartPower project at hp labs seeks to address these challenges through holistic solutions, across multiple levels of the system, and optimized for the overall end-user experience. In this talk, I will motivate the power management challenge and present a systematic taxonomy of inefficiencies that lead to overconsumption of power. I will then present results from four major projects that address these inefficiencies - energy-aware user interfaces, heterogeneity-based architectures, ensemble-level power control, and integrated IT/facilities resource provisioning. Though these approaches straddle different market segments and different levels of the system, they all achieve dramatic improvements, with factors of two to twenty reduction in the power consumption. I will conclude with a discussion of some of the toolsets developed as part of this project and ongoing and future work.
