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.
