DescriptionIn June 2008, Roadrunner sped past the 1 petaflop/s milestone, clocking in at 1.026 petaflops/s. Ten short years later in June 2018, Summit has now taken over the as the world’s fastest supercomputer spot by achieving 122.3 petaflops/s. What is remarkable is that the over 100x scaling up of performance was achieved with less than 4x scaling of hardware power. In this talk, I will highlight the key advances in energy-efficiency that made possible this superscaling of performance with a particular focus on the influence of linear algebra and graph algorithms. I will also speculate on trajectories for their continued development to meet the demands of data centric computing as we face slow-downs in reducing the power consumption of transistors.
