The Green 500: Trends in Energy-Efficient Supercomputing

With power being 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. 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. This BoF presents on-going improvements and case studies from sites that have made power submissions to the Green500.
