A Japanese supercomputer called Fugaku, installed in the city of Kobe by the government-sponsored Riken institute, took first place in a twice-yearly speed ranking that was released on Monday.

The Japanese machine carried out 2.8 times more calculations a second than an IBM system at Oak Ridge National Laboratory in Tennessee, which Fugaku bumped to second place in the so-called Top 500 list.

Fugaku also attained top spots in other rankings that test computers on different workloads, including Graph 500, HPL-AI, and HPCG. No previous supercomputer has ever led all four rankings at once.

The Top500 list, compiled by researchers in the United States and Germany, is being released to coincide with a supercomputing event that is ordinarily held in Frankfurt but that is going virtual this year because of the coronavirus pandemic.
