Video: Introduction to the Cheyenne Supercomputer

Brian Vanderwende, UCAR

Cheyenne is a new 5.34-petaflops, high-performance computer built for NCAR by SGI. Cheyenne be a critical tool for researchers across the country studying climate change, severe weather, geomagnetic storms, seismic activity, air quality, wildfires, and other important geoscience topics.

In this video, Brian Vanderwende from UCAR describes typical workflows in the NCAR/CISL Cheyenne HPC environment as well as performance and operational differences between the Yellowstone and Cheyenne systems.

The Cheyenne system was released for production work on January 12, 2017. Built on the SGI ICE XA cluster platform, the Cheyenne supercomputer features 145,152 latest-generation Intel Xeon processor cores in 4,032 dual-socket nodes (36 cores/node) and 313 TB of total memory.

Topics in this video include:

  • Technical specifications for Cheyenne and the expanded GLADE file systems
  • The Cheyenne computing environment
  • Accessing software, including compilers and MPI libraries
  • Submitting batch jobs using the PBS scheduler
