The United States is back in first place. on the list of the 500 most powerful supercomputers in the world. has achieved it with Frontier, installed at the Oak Ridge National Laboratory. This supercomputer, which runs on AMD EPYC CPUs, and has taken it from Japan, which until now had Fugakua system with ARM A64X, not only its most powerful supercomputer, but also the fastest in the world.
Frontier is still in the process of being integrated and testing at its Tennessee location, but some details about it are already known. For example, who will be in charge of operating it in the first place: the Air Force and the Department of Energy of the United States.
This supercomputer is powered by HPE’s Cray EX platform, is the first known true hexascalar system, reaching a power of 1.1 hexaflops on the Linmark benchmark. For its part, Fugaku has a much lower power: 442 petaflops, which has nevertheless been enough for it to have remained at the top of the list of the most powerful supercomputers in the world for two years.
As well as being the most powerful supercomputer, Frontier is also the most efficient. It works at 52.23 Gigaflops per watt, surpassing the most efficient computer so far on the Green500 list: the also Japanese MN-3.
Aside from the top spot, the United States also has other supercomputers in the top 10 on the list. Specifically, those who occupy the fourth, fifth, seventh and eighth places on the list, which has just been announced at the International Supercomputing Conference. The systems located in Europe have not behaved badly either.
finnish supercomputer LUMI ranks third on the list, ahead of the American Summit, and the French adastra, the second most powerful supercomputer in Europe, ranks tenth. As it happens, both are also based on HPE’s Cray EX platform, using the 3rd generation EPYC chip as CPUs and Instinct GPUs.
