HPCG - November 2023

The TOP500 list has incorporated the High-Performance Conjugate Gradient (HPCG) benchmark results, which provide an alternative metric for assessing supercomputer performance. This score is meant to complement the HPL measurement to give a fuller understanding of the machine.

Like on the June 2023 list, Fugaku remains the leader with an HPCG benchmark of 16 PFlop/s. Frontier claimed the No. 2 spot with 14.05 HPCG-PFlop/s and No. 3 was taken by LUMI with 4.59 HPCG-PFlop/s.

Rmax and Rpeak values are in PFlop/s. For more details about other fields, check the TOP500 description.

Rpeak values are calculated using the advertised clock rate of the CPU. For the efficiency of the systems you should take into account the Turbo CPU clock rate where it applies.
