HPCG - June 2021

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

Fugaku, the clear winner of the TOP500, stayed consistent with last year's results with 16.0 HPCG-petaflops. Summit also stuck with the results from last year, with Summit achieving 2.93 HPCG-petaflops and Perlmutter, a new system, benchmarking with 1.91 HPCG-petaflops.

HPL-AI Results

The HPL-AI benchmark seeks to highlight the convergence of HPC and artificial intelligence (AI) workloads based on machine learning and deep learning by solving a system of linear equations using novel, mixed-precision algorithms that exploit modern hardware.

Much like the TOP500, RIKEN's Fugaku system is leading the pack here. As stated, this machine is considered by some to be the first "Exascale" supercomputer. Fugaku demonstrated this new level of performance on the new HPL-AI benchmark with 2 Exaflops
