27 January 2021 - New NCAR supercomputer to be built by Hewlett Packard Enterprise

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).
