Cray, the supercomputer maker, is building a supercomputer for the U.S. Navy that uses the AMD Epyc Rome processor and Nvidia’s Volta GPU. Built on the Shasta platform, it has a performance of 12.8 petaflops, making it one of the top 20 most powerful supercomputers in the world today.
The Cray Shasta computer is part of the Defense Department’s High Performance Computing Modernization Program and will be installed in the Navy DSRC at the Stennis Space Center in Mississippi. This will be the first machine in the program to provide more than 10 petaflops computing power. The supercomputer will be equipped with some important hardware, including 290304 AMD Epyc 7002 processor cores, 112 Nvidia Volta V100 GPUs, and 200 gigabit per second of the Cray Slingshot network interconnection. There is also incredible 590TB of memory and 14 petabytes of available storage, including 1 PB of NVMe-based SSD SSDs.
The system is expected to be operational in early 2021 and will be used for aircraft, ship and environment modeling. It can also be used for weather forecasting, such as tracking hurricanes and their intensity. As of Last November, the 148.6petaflop Summit system was the world’s most powerful supercomputer. It has 4,356 nodes, each containing two Power9 CPUs with 22 cores and six Nvidia Tesla V100 GPUs.
