Highlights - June 2019

This is the 53rd edition of the TOP500.

For the first time only Petaflop systems made the list. The total aggregate performance of all 500 system has now risen to 1.56 Exaflops.

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 kept the first two positions in the TOP500 in the USA. The Summit system slightly improved it’s High Performance Linpack (HPL) since the last TOP500 listing half a year ago.  

The number of installations in China continues to rise strongly. 44.0 % of all system are now listed as being installed in China. The number of system listed in the USA remains near it's all time low at 23.2 %. However, systems in the USA are on average larger, which allowed the USA (38.5%) to stay close to China (29.9%) in terms of installed performance.

Highlights from the List

  • For the first time the TOP500 contains only Pflop-systems.

  • A total of 134 systems on the list are using accelerator/co-processor technology, down from 138 six months ago. 0 of these use NVIDIA Ampere chips, 62 use NVIDIA Volta, and there are now 0 systems with 17.

  • Intel continues to provide the processors for the largest share (95.60 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 1,021.00 Tflop/s mark on the Linpack benchmark.

  • The last system on the newest list was listed at position 406 in the previous TOP500.

  • Total combined performance of all 500 exceeded the Exaflop barrier with now 1.56 exaflop/s (Eflop/s) up from 1.41 exaflop/s (Eflop/s) 6 months ago.

  • The entry point for the TOP100 increased to 2,395,680.00 Pflop/s.

  • The average concurrency level in the TOP500 is 118,213 cores per system up from 118,173 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.

Corrections: The Shoubu system was removed from the TOP500 list after the TOP500 team was notified it was decommissioned and is no longer the most energy efficient system on the TOP500 list
