7th HPCG Performance List

7th HPCG Performance List

HPCG Performance List was announced at a BOF at ISC 2017

HPCG results are now integrated into the TOP500 list.

The High Performance Conjugate Gradients (HPCG) Benchmark list was announced on June 21, 2017 at ISC 2017. This is the seventh list produced for the benchmark designed to complement the traditional High Performance LINPACK (HPL) benchmark used as the official metric for ranking the TOP500 systems. The first HPCG list was announced at ISC 2014 three years ago, containing only 15 entries. Since then HPCG list was released twice a year, the number of entries has steadily increased. The current list contains 110 entries as HPCG continues to gain traction in the HPC community.

The 7th list contains entries from many of the TOP500's highest ranked, mainly top 50 systems, but continues to provide a significantly different ordering. Of particular note is the ranking of the Sunway TaihuLight, which remains at the top of the HPL list for the third time, but has dropped from third (ISC 2016) to fourth (SC16) and back to third on the current HPCG list. For HPL, the Sunway system was about 3 times faster than the second place system (Tianhe-2). For HPCG, it is about 2 times slower than the fastest machine.

The highlights from the 7th HPCG list:

  • HPCG list of supercomputing sites now features 110 entries, most majority of them from the very top of the TOP500 list.
  • The Riken/Fujitsu K Computer is in first place, a spot it claimed at SC16.
  • The upgraded Piz Daint system from CSCS is fourth on the list.
  • The Sunway TaihuLight system is ranked 3rd for HPCG, despite being ranked 1st for TOP500.
  • The HPCG list has been integrated into the TOP500 list for the first time.
  • The relative difference of the third and fourth system is less than 1% and they were jointly recognized at the BOF.
