Frontier Keeps Top Supercomputer Spot

The Frontier supercomputer.

Top500 coauthor Jack Dongarra acknowledged that not all the systems on the Top500 are being used for scientific computing, adding that one way to get a better sense of the real HPC machines is to look at the top 100 or 200 systems on the list.

The Frontier system at the U.S. Department of Energy's Oak Ridge National Laboratory remained the world's top supercomputer on the 60th Top500 list, clocking 1.102 exaflops and scoring highest on the HPL-MxP benchmark with 7.9 exaflops.

The third-highest-ranking supercomputer, Finland’s Lumi, had the second-highest HPL-MxP score with 2.2 exaflops, while Japan's second-ranked Fugaku supercomputer earned the third-highest HPL-MxP position with 2.0 exaflops.

Fugaku held its lead position on the High Performance Conjugate Gradients benchmark with 16 Linpack petaflops, while Frontier scored second with 14 petaflops.

Lumi grew its computational footprint, raising its score from 151.9 to 309.1 petaflops.
