Events: 10th HPCG Performance List
10th HPCG Performance List
HPCG Performance List was announced at a BOF at SC18

The HPCG results continue to be integrated into the TOP500 list. The 10th edition of the HPCG list of results contains the complete list of submissions some of which might have not made the TOP500 list.

The 10th edition of the bi-annual High Performance Conjugate Gradients (HPCG) Benchmark list was announced on November 13, 2018 at the SC18 conference in Dallas, TX, USA. The session entitled HPCG Benchmark Update took place on Tuesday, November 13, 2018 in Room D167 at 12:15pm in Kay Bailey Hutchison Convention Center Dallas.

This is the tenth 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 over four years ago, containing only 15 entries. Since then, HPCG list was released bi-annually and the number of entries has steadily increased as the new results became available. The current list contains 140 entries as HPCG continues to gain traction in the HPC community.

It is now customary that the new list contains entries from many of the TOP500's highest ranked systems, mainly the top-50. The current list is no exception. However, the HPCG ranking continues to provide a significantly different ordering of the machines when compared with the TOP500 ranking. A major change in TOP500 ranking is now reflected in the HPCG results. Summit and Sierra supercomputers lead the HPCG list with their score breaking the 1 Pflop/s barrier and almost approaching 3 Pflop/s for the number 1 system.

Summary highlights from the 10th HPCG list include:

  • Only US and Japanese systems in top 5.
  • A few large machines received upgrades and higher HPCG scores including Piz Daint, Electra, SuperMUC, Endeavor.
  • The first ARM system made appearance on the list. It is called Astra and is hosted at Sandia National Laboratories.
  • More than 140 systems are now recorded on the list despite retirement of some machines from the previous list.
