11/2018 Highlights

  • Summit and Sierra improved in performance and brought the #1 and #2 spot back to the USA

  • The No 7 system SuperMuc is newly installed. A few other systems (No 1, 2, 6) improved in performance.

  • Summit, an IBM-built system at the Oak Ridge National Laboratory (ORNL) in Tennessee, USA, remains at the #1 spot with an improved performance of 143.5 Pflop/s on the HPL benchmark, which is used to rank the TOP500 list. Summit has 4,356 nodes, each one housing two Power9 CPUs with 22 cores each and six NVIDIA Tesla V100 GPUs each with 80 streaming multiprocessors (SM). The nodes are linked together with a Mellanox dual-rail EDR InfiniBand network.

  • Sierra, a system at the Lawrence Livermore National Laboratory, CA, USA moved up one rank and is now listed at #2. It’s architecture is very similar to the new #1 systems Summit. It is build with 4,320 nodes with two Power9 CPUs and four NVIDIA Tesla V100 GPUs. Sierra achieved 94.6 Pflop/s.

  • Sunway TaihuLight, a system developed by China’s National Research Center of Parallel Computer Engineering & Technology (NRCPC) and installed at the National Supercomputing Center in Wuxi, which is in China's Jiangsu province was in the lead for 2 years, but was mow pushed to the #3 position with 93 Pflop/s.

  • Tianhe-2A (Milky Way-2A), a system developed by China’s National University of Defense Technology (NUDT) and deployed at the National Supercomputer Center in Guangzho, China was upgraded earlier this year by replacing the Xeon PHI accelerators with the new proprietary Matrix-2000 chips. It is now the No. 4 system with 61.4 Pflop/s.

  • The No. 5 is the Piz Daint, a Cray XC50 system installed at the Swiss National Supercomputing Centre (CSCS) in Lugano, Switzerland and the most powerful system in Europe.
