Energy efficiency in HPC data centers: Latest advances to build the path to exascale

Abstract

Nowadays, moderating energy consumption and building eco-friendly computing infrastructure is a major goal in large data centers. Moreover, data center energy usage has risen dramatically over the past decade and will continue to grow in-step with the High Performance Computing (HPC) intensive workloads which are at the heart of our modern life. The recent advances in the technology has driven the data center into a new phase of expansion featuring solutions with higher density. To this end, much has been done to increase server efficiency and IT space utilization. In this chapter, we will provide a state-of-the-art overview as regards energy-efficiency in High Performance Computing (HPC) facilities while describing the open challenges the research community has to face in the coming years to enable the building and usage of an Exascale platform by 2020.
