Abstract: With 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.
