Perlmutter (supercomputer)

Perlmutter (also known as NERSC-9) is a supercomputer scheduled to be delivered to the United States Department of Energy in 2020.[2] It is being built by Cray and is based on their upcoming Shasta architecture which is planned to utilize Zen 3 based AMD Epyc CPUs ("Milan") and next-generation Nvidia Tesla GPUs[3]. Its intended use-cases are nuclear fusion simulations, climate projections and material and biological research[4]. It is predicted to reach approximately 100 PFLOPS of processing power[5]
