7th HPCG Performance list released - HPCG results are integrated into the TOP500 list

21 Jun 2017 Frankfurt - The High Performance Conjugate Gradients (HPCG) Benchmark list has been announced at ISC'17. This is the seventh list produced for the emerging benchmark designed to complement the traditional High Performance LINPACK (HPL) benchmark used as the official metric for ranking the TOP 500 systems. The first HPCG list was announced at ISC'14 three years ago, containing only 15 entries. Release 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 systems, but continues to provide a significantly different ordering. Of particular node 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 (ISC16) to fourth (SC16) to fifth on the current HPCG list. For HPL, the Sunway system was about 3 times faster than the second place system, the Tianhe-2. For HPCG, it is about 2 times slower than the fastest machine.

The seventh HPCG Performance List has been presented at ISC'17 on June 2017.

The highlights are the following:

  • the HPCG list of supercomputing sites now features 110 entries, the 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 third on the list.
  • the Sunway TaihuLight system is ranked 5th for HPCG, despite being ranked 1st for the TOP500.
  • the HPCG list has been integrated into the TOP500 list for the first time.
