US government builds exascale supercomputer

for Nuclear safety service
The US Department of Energy has set aside $ 600 million for the construction of a third exascale supercomputer. Cray is going to build the supercomputer for the National Nuclear Security Administration, which manages the US nuclear weapons arsenal.

The new supercomputer cluster is named El Capitan can, according to the US ministry, continue to provide a computing power of 1.5 exaflops. The system must be completed by the end of 2022. Cray is going to build the supercomputer on the basis of his Shasta platform, where each compute blade consists of four nodes . It is not yet known what hardware will come in and how many blades the exascale cluster will consist of. This is probably hardware that is not yet available and has not yet been announced.

Cray already has two other assignments from the US Department of Energy for the construction of exascale super computers for scientific research. It is about the Aurora with Intel hardware and the Frontier with AMD hardware . The Aurora consists of Xeon processors, Optane memory and Intel Xe gpus and receives a calculation power of one exaflops. Epyc processors and Radeon accelerators end up in the Frontier and the cluster must be capable of handling 1.5 exaflops. That system therefore seems to be just as fast as the El Capitan supercomputer, but it is specifically stated for that new cluster that the computing power of 1.5 exaflops can be delivered continuously and that the peak performance is even higher.

The three systems that Cray is building for the US government are 1.5 billion dollars in total. All three clusters use the Shasta platform that uses the Slingshot interconnect developed by Cray for interconnections. Cray also announces Tuesday to develop a new software platform for its exascale clusters.

El Capitan is made for the NNSA, the part of the US Department of Energy that is responsible for all nuclear weapons in the country and the drive of nuclear submarines and aircraft carriers. The national nuclear security service says it will use the computing power to investigate the maintenance of the current nuclear arsenal.

The coming exascale computers offer a computing power of at least one exaflops, or 10 18 floating operations per second . This makes them much faster than the current supercomputers in use. The US Department of Energy’s IBM Summit system is currently the fastest supercomputer with a performance of 143.5 petaflops and a peak of 200.8 petaflops. China has set itself the goal of having an exascale supercomputer ready by 2020 and would like to use its own processors for this. Details about the construction of Tianhe-3 appeared in May.
