Cray is building new Shasta Supercomputers. The first will be built for $146 million at Berkeley National Labs. It will use AMD Epyc processor and the next-generation Einstein Nvidia Tesla GPU accelerator. The “Perlmutter” NERSC-9 supercomputer will be installed in late 2020.
Cray has built a new interconnect, called “Slingshot”.
The current Cori NERSC-8 machine at LBNL is a Cray XC40 system using the company’s “Aries” interconnect. There are 14 cabinets. The Cori system has 32.3 peak petaflops using Xeon and Xeon Phi nodes. It cost $75 million, or $2,321 per teraflops
They are aiming for the Shasta supercomputer to have 3 to 4 times the processing power of the Cori.
Shasta should have 97 to 130 petaflops.
