NSF National Center for Atmospheric Research
Resource Type: Compute
User Guide: https://arc.ucar.edu/docs
Recommended Use: Through the ACCESS program, NSF NCAR accepts Explore ACCESS or Discover ACCESS requests from U.S.-based researchers with an NSF award in the Earth system sciences or <i>related to</i> Earth system science. Derecho is also available to graduate students, postdocs, and new faculty whose Earth system science–related work does not have external support. Derecho can also be used in a classroom or instructional setting. Additional Derecho allocation options, including opportunities for large-scale projects are managed separately by NSF NCAR.

Description: The Derecho supercomputer is a 19.87-petaflops HPE Cray EX cluster with 2,488 nodes, each with two 64-core AMD EPYC 7763 Milan processors, for a total of 323,712 processor cores. Each node has 256 GB DDR4 memory per node. The Derecho nodes are connected by an HPE Slingshot v11 high-speed interconnect in a dragonfly topology. The NSF National Center for Atmospheric Research (NCAR) operates the Derecho system to support Earth system science and related research by researchers at U.S. institutions.
