US Navy gets supercomputer with AMD Epyc and Nvidia Volta V100 chips

The US Navy is getting a Cray Shasta supercomputer with a peak computing power of 12.8 petaflops. The computing power comes from AMD Epyc 7002 processors and 112 Nvidia V100 GPUs.

The Navy Department of Defense Supercomputing Resource Center does not disclose which Epyc 7002 models the supercomputer will receive and how many processors it will be, but it does say that it involves 290,304 cores and that there are 112 Volta V100 general-purpose graphics processing units.

The supercomputer will also receive Cray Slingshot interconnects, with a bandwidth of 200Gbit/s, 590TB of memory and 14 petabytes of storage, of which 1 petabyte is nvme-ssd storage. With an Rpeak of 12.8 petaflops, the respective Cray Shasta would enter the top 25 of the current Top500 list of the world’s most powerful supercomputers. However, the system is not expected to be ready until early 2021, by which time the list will look different.

The Navy will use the supercomputer to create climate, weather and ocean models that can assist the fleet in their work. In addition, the computing power will be available for the design of ships and aircraft for the American defense.
