On June 22, a new TOP500 of supercomputers was published, with a new leader. The Japanese Fugaki supercomputer, built on 52 (48 computing + 4 under OS) core A64FX processors, took first place, overtaking the previous leader, the Summit supercomputer built on Power9 and NVIDIA Tesla in the Linpack test. This supercomputer runs Red Hat Enterprise Linux 8 with a Linux-based hybrid kernel and McKernel.
ARM processors are used in only four computers from the TOP500, and 3 of them are built on Fujitsu's A64FX.
Despite the use of processors on the ARM architecture, the new computer is only in 9th place in terms of energy efficiency with a parameter of 14.67 Gflops / W, while the leader in this category, the MN-3 supercomputer (395th place in the TOP500), provides 21.1 Gflops / W.
After the commissioning of Fugaki, Japan, with only 30 supercomputers from the list, provides about a quarter of the total computing power (530 Pflops out of 2.23 Eflops).
The most powerful computer in Russia, "Christofari", which is part of the Sberbank cloud platform, is in 36th place and provides approximately 1.6% of the maximum performance of the new leader.
