Summit at ORNL still No. 2 supercomputer

The Summit supercomputer at Oak Ridge National Laboratory remained the fastest system in the United States and the second-most powerful in the world in the biannual TOP500 list released Monday.

Fugaku in Kobe, Japan, remained No. 1, where it has been since June 2020. The 442-petaflop system has been at the top of the list four consecutive times.

Summit, an IBM system, was the world’s most powerful supercomputer from June 2018 to November 2019, when the U.S. Department of Energy had the two fastest systems in the world. DOE still has the second and third most powerful supercomputers, Summit at number two and Sierra at Lawrence Livermore National Laboratory in California at number three.

Fugaku is installed at the Riken Center for Computational Science. It was co-developed by Riken and Fujitsu, and it has 7,630,848 cores. It is based on Fujitsu’s custom ARM A64FX processor, TOP500 said. Fugaku uses a Fujitsu interconnect known as Tofu D to transfer data between nodes.

TOP500 said Fugaku’s 442-petaflop performance on a benchmark test makes it three times as powerful as Summit, which has 2,414,592 cores. The TOP500 list uses a benchmark test to rank the world’s most powerful supercomputers.
