The US has long been the leader in the supercomputer field, first through Cray's almost uninterrupted dominance of the field, and later through a variety of technology companies. Japan made major strides in the field in the 1980s and 90s, with China becoming increasingly active in the field. As of June 2020, the fastest supercomputer on the TOP500 supercomputer list is Fugaku, in Japan, with a LINPACK benchmark score of 415 PFLOPS, followed by Summit, by around 266.7 PFLOPS. The US has four of the top 10; China and Italy have two each, Switzerland has one. In June 2018, all combined supercomputers on the list broke the 1 exaFLOPS mark.
