SUMMARY:Superscaling Performance through Energy-Efficient Supercomputing
DESCRIPTION:Padma Raghavan (Vanderbilt University)\n\nIn June 2008, Roadru
 nner 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 th
 e 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 highlig
 ht the key advances in energy-efficiency that made possible this superscal
 ing of performance with a particular focus on the influence of linear alge
 bra 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.\n\nRegis
