  1. Lecture 11.1 Top 500 EN 600.320/420/620 Instructor: Randal Burns 5 March 2018 Department of Computer Science, Johns Hopkins University

  2. TOP500 http://ornl.gov/info/ornlreview/v45_3_12/images/a04_p10_lrg.jpg  Fastest 500 computing machines According to LINPACK benchmark – Supposed to be general purpose –  Controversial Other metrics represent other problems – Graph500: data-intensive supercomputing – Green500: best computing power per watt –  Currently “ Sunway TaihuLight ” Xiwu Chine 93 TFlops, 10,649,000 cores, 15,371 kW – All Chinese hardware – Lecture 3: Parallel Architectures

  3. Top500 Growth (Exascale coming) Lecture 3: Parallel Architectures

  4. Top500: Flops/KW Lecture 3: Parallel Architectures

  5. Top 500 Evolution Lecture 3: Parallel Architectures

  6. Who has supercomputers?  Industry increasingly Lecture 3: Parallel Architectures

  7. Green 500  MFlops/watt – Power efficiency will be the limited factor in reaching exascale computing – Also co-branded as environmentally friendly  Lists dominated by heterogeneous computers – #1 = Shoubu (RIKEN) 6673.84 MFLOPS/Watt – Intel Xeon with PEZY-SCnp accelerators Lecture 3: Parallel Architectures
