HPCG Performance List announced at ISC 2021

The new HPCG Performance List was announced at the ISC 2021 virtual event. The session entitled HPCG Benchmark Update took place on Wednesday, June 30, 2021.

Some of the HPCG results are now integrated into the TOP500 list. The main HPCG list of results contains the complete list of submissions some of which might have not made the TOP500 list due to a number of factors like low HPL benchmark result or missing the submission deadline.

The bi-annual High Performance Conjugate Gradients (HPCG) Benchmark list was announced on June 30, 2020 at the ISC 2020 conference.

This is the fifteenth 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 six 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 nearly 200 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, mainly top-50 systems — in total, there are now 92 systems shared between the lists. The current list is no exception. However, the HPCG ranking continues to provide a significantly different ordering of the machines when compared to the TOP500 ranking. A major change in TOP500 ranking is now reflected in the HPCG results. Fugaku system from Japan leads the list with over 13 Pflop/s of achieved performance. Summit is still in second position but Sierra supercomputer was now replaced with the new entry: Perlmutter. More than half of top-10 entries now break the 1 Pflop/s barrier.

Summary highlights from the 15th HPCG list include:

• The Fugaku housed at RIKEN continues as #1 system.
• Entering the top-10 part of the list now requires performance exceeding three-quarters of a Peta-flop.
