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.
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.
