Perlmutter—also referred to as NERSC-9—is a supercomputer installed at the National Energy Research Scientific Computing Center, part of the United States Department of Energy. It succeeds the Cori system. Developed by Cray utilizing their Shasta platform, it incorporates Zen 3 architecture AMD Epyc processors ("Milan") alongside Nvidia Tesla graphics processing units. Its primary use cases encompass simulations of nuclear fusion, climate modeling, and research in materials science and biology. The initial phase, finalized on May 27, 2022, delivered a computational capacity of 70.9 PFLOPS.
Equipped with Nvidia A100 GPUs and AMD Milan CPUs, each node contains 256 GiB of memory. The system includes 35 petabytes of storage managed through a shared all-flash Lustre file system capable of 5 terabytes per second throughput. Perlmutter operates on a specialized Linux-based kernel and is named in honor of Nobel Prize winner Saul Perlmutter.
