The United States are at the top of the world of supercomputers in the ranking Top 500 of the most powerful systems.
O Frontier HPE Cray EX by ORNL with processors AMD is the “first real system exascale“. Its Frontier system Oak Ridge National Laboratory (ORNL) working with AMD EPYC CPU took first place from last year's champion, the system ARM A64X Fugaku of Japan.
It is still in the process of completion and testing at ORNL in Tennessee, and when completed will be used by the U.S. Air Force and the U.S. Department of Energy.
Ο Frontier, powered by the platform Hewlett Packard Enterprise (HPE) Cray EX, was also the top machine by far. This is the first (known) real system exascale, with a maximum 1,1 exaflops on the Linmark benchmark. Fugaku, meanwhile, managed less than half, 442 petaflops, which, however, was enough to keep it in first place for the previous two years.
Frontier was also the most efficient supercomputer. Working with just 52,23 gigaflops per watt, defeated the Japanese MN-3 system and took first place in the list Green500. "The fact that it's the fastest system in the world and the most energy efficient is simply amazing", Said the director of the ORNL laboratory, Thomas Zacharias, at a press conference.
Other machines at TOP10 include another system HPE Cray EX installed on EuroHPC in Finland (151,9 petaflops), the Summit system developed by IBM and using 22-core Power CPUs and NVIDIA Tesla V100 GPUs (148,8 petaflops) and Sierra of Lawrence Livermore, a smaller-scale version of Summit that reached 94,6 Pflop / s.
China held two places in the top ten with him Sunway TaihuLight from the National Research Center for Parallel Engineering & Computer Technology (NRCPC) and the Tianhe-2 to built by the National University of Defense Technology (NUDT) of China.
However, it is rumored that China already has no less than two exascale systems (according to the benchmark Linmark) in the new systems Sunway Oceanlite and Tianhe-3. However, due to the current state of semiconductor policy, China is reportedly not revealing new benchmarks or significant developments.
