The Oak Ridge National Laboratory under the US Department of Energy launched the Summit computing complex, which claims to be the most powerful supercomputer in the world. Its performance is 200 petaflops, which is eight times better than its predecessor, the Titan supercomputer, built in the same laboratory. The reason for the appearance of such a monster is called the irrepressible appetites of scientists.
Summit is based on the IBM AC922 platform, which includes 4608 individual servers. Each of them is equipped with two 22-core IBM Power9 processors, plus 6 NVIDIA Tesla V100 GPUs, data transfer is provided by a two-channel Mellanox EDR 100 Gb / s InfiniBand communication backbone. An incredible 10 petabyte memory array and special high-speed data communication buses were created for the supercomputer.
Mentioning scientists was not just like that, Summit became the first supercomputer capable of processing the results of experiments from the category of "exascale calculations", from a billion billion calculations per second. A cherished dream for those working with high energy physics, AI and advanced medical issues. Summit, in particular, will help analyze all cancer cases in the United States and simulate materials that have not yet existed at the atomic level.
And if we abstract from practical tasks and move on to political ones, then this supercomputer is the first in a series of clusters, which, according to the plan of the US authorities, will turn into a new eco-system of supercomputers by 2021. It is needed so that the concept of "limit of computing power" ceases to be relevant, and tasks of any complexity would be solved in a working order, unlike in other countries. The name of this system has not yet been announced, but many will agree that Skynet suggests itself.
