Frontier Supercomputer Retains Lead on TOP500 List


The Frontier system is the first U.S. supercomputer to achieve exascale performance.

The Frontier system at Oak Ridge National Laboratory (ORNL) is the top-performing supercomputer in the world, according to the recently released 60th edition of the TOP500 list.

Frontier is the first U.S. supercomputing system with a performance exceeding one EFlop/s, the report says. “Frontier is the clear winner of the race to exascale, and it will require a lot of work and innovation to knock it from the top spot.”

The Top 5

  • Frontier — The HPE Cray EX system is installed at ORNL in Tennessee, “where it is operated for the Department of Energy (DOE). It currently has achieved 1.102 EFlop/s using 8,730,112 cores,” says the report.
  • Fugaku — The Fugaku system installed at the RIKEN Center for Computational Science in Kobe, Japan remains at #2 with an HPL score of 0.442 EFlop/s.
  • LUMI — This HPE Cray EX system at the EuroHPC center at CSC in Finland underwent a major upgrade to hold on to the #3 spot, with a score of 0.309 EFlop/s.
  • Leonardo — At #4, the new Leonardo system installed at EuroHPC/CINECA in Bologna, Italy scored 0.174 EFlop/s with 1,463,616 cores. 
  • Summit — This IBM-built system, also at ORNL, rounds out the top five with a score of 148.8 Pflop/s on the HPL benchmark.
