Highlights

This is the 52nd edition of the TOP500.

Two IBM build systems called Summit and Sierra and installed at DOE’s Oak Ridge National Laboratory (ORNL) in Tennessee and Lawrence Livermore National Laboratory in California brought back the first two positions in the TOP500 to the USA. Both system improved their High Performance Linpack (HPL) since they appeared on the TOP500 listing half a year ago. 

The number of installations in China continues to rise strongly. 45 percent of all system are now listed as being installed in China. The number of system listed in the USA continues to decline and has now reached an all time low of 22 percent.  However, systems in the USA are on average larger, which allowed the USA (38%) to stay ahead of China (31%) in terms of installed performance.

The impact of the new technology of the Summit and Sierra system is also visible in the HPCG benchmark rating and the Green 500. Both system hold the top positions on the HPCG ranking ahead of Japans K-Computer as No 3. On the Green 500, which is traditionally dominated by smaller and more experimental system, they managed to be listed at No 6 and No 8. The Green 500 is again lead by the Shoubu System B at RIKEN in Japan.

Highlights from the List

  • There are 429 systems with performance greater than a petaflop/s on the list, up from 272 six months ago.

  • A total of 138 systems on the list are using accelerator/co-processor technology, up from 110 six months ago. 64 of these use Nvidia Pascal chips, 46 use NVIDIA Volta, and there are now 13 systems with Nvidia Kepler.

  • Intel continues to provide the processors for the largest share (95.20 percent) of TOP500 systems.

  • We have incorporated the HPCG benchmark results into the Top500 list to provide a more balanced look at performance.

  • The 2 top DOE systems Sierra and Summit also lead with respect to HPCG performance. They are followed by the Japanese K-Computer, which due to its balanced architecture and comparable high memory bandwidth remains the No 3 on the HPCG list.

  • Japanese systems continue to take leading roles in the Green500. However, the top 2 DOE systems Sierra and Summit also make the top10 in the Green500 and demonstrate the progress in performance efficiency.

  • The entry level to the list moved up to the 874.8 Tflop/s mark on the Linpack benchmark.

  • The last system on the newest list was listed at position 342 in the previous TOP500.

  • Total combined performance of all 500 exceeded the Exaflop barrier with now 1.41 exaflop/s (Eflop/s) up from 1.21 exaflop/s (Eflop/s) 6 months ago.

  • The entry point for the TOP100 increased to 1.97 Pflop/s.

  • The average concurrency level in the TOP500 is 118,173 cores per system up from 116,111 six months ago.

About the TOP500 List

The first version of what became today’s TOP500 list started as an exercise for a small conference in Germany in June 1993. Out of curiosity, the authors decided to revisit the list in November 1993 to see how things had changed. About that time they realized they might be onto something and decided to continue compiling the list, which is now a much-anticipated, much-watched and much-debated twice-yearly event.
