NCAR has announced that Hewlett Packard Enterprise (HPE) will build the next supercomputer to be installed at the NCAR-Wyoming Supercomputing Center in Cheyenne, Wyoming. 

The HPE Cray EX cluster will be delivered in the fall of 2021 and will become operational in early 2022. The 19.87-petaflops system, which NCAR plans to name soon, is expected to deliver about 3.5 times the scientific throughput of the current Cheyenne supercomputer. The new system will get 20% of its sustained computing capability from graphics processing units (GPUs), with the remainder coming from traditional central processing units (CPUs).

The system will have 2,488 traditional compute nodes, each with two 64-core AMD processors and 256 GB of memory, and 82 GPU nodes, each with four NVIDIA A100 GPUs, 40 GB HBM2 memory, and NVLink interconnect. The nodes will be linked by an HPE Cray Slingshot high-speed interconnect.
