HPCG - November 2021

The TOP500 list has incorporated the High-Performance Conjugate Gradient (HPCG) Benchmark results, which provide an alternative metric for assessing supercomputer performance and is meant to complement the HPL measurement.

The HPCG results here are very similar to the last list. Fugaku was the clear winner with 16.0 HPCG-petaflops, while Summit retained its No. 2 spot with 2.93 HPCG-petaflops. Perlmutter, a USA machine housed at Lawrence Berkeley National Laboratory, took the No. 3 spot with 1.91 HPCG-petaflops.
