Perlmutter (supercomputer)

Perlmutter (also known as NERSC-9) is a supercomputer delivered to the National Energy Research Scientific Computing Center of the United States Department of Energy as the successor to Cori.^[2] It is being built by Cray and is based on their Shasta architecture which utilizes Zen 3 based AMD Epyc CPUs ("Milan") and Nvidia Tesla GPUs. Its intended use-cases are nuclear fusion simulations, climate projections, and material and biological research.^[3] Phase 1, completed May 27, 2022,^[4] reached 70.9 PFLOPS of processing power.^[5]
