DescriptionWith power becoming a first-order design constraint on-par with performance, it is important to measure and analyze energy-efficiency trends in supercomputing. To raise the awareness of greenness as a first-order design constraint, the Green500 seeks to characterize the energy-efficiency of supercomputers for different metrics, workloads, and methodologies. Based on this characterization, it also provides a ranking of the most energy-efficient supercomputers in the world. This BoF discusses trends across the Green500 and highlights from the current Green500 list.

In addition, the Green500, Top500, and Energy Efficient HPC Working Group have been working together on improving power measurement methodology and this BoF presents case studies from sites that have made power submissions that meet the highest quality level of measurement methodology. This highest quality level requires a full-system energy measurement and improves the accuracy and reproducibility of the information reported on the Green500 list compared to lower quality measurements.

The goals of this BoF are multi-fold: (1) analyze and announce the latest Green500 List, (2) present technical details and analysis on three of the most energy-efficient supercomputers, and (3) present case studies on improving quality and accuracy aspects of the power measurement methodology.
