The US General Services Administration, an independent agency of the US government tasked with supporting and helping the basic functioning aspects of federal agencies, has officially auctioned off its Cheyenne Supercomputer. The 5.34-petaflops system located at the NCAR-Wyoming Supercomputing Center (NWSC) in Cheyenne, Wyoming, was the 20th most powerful supercomputer in the world in 2016, and as of November 2023, it's ranked 160th.

Despite its seemingly low ranking the Cheyenne Supercomputer is still a powerful beast of a computer with capabilities such as carrying out 5.34 quadrillion calculations per second. The supercomputer was typically used to carry out weather predictions and predicting natural disasters.

Under its hood is where it gets really interesting, as Cheyenne features 8,064 Intel "Broadwell" Xeon processors (18-core 2.3GHz E5-2697v4) for a total core count of 145,152. Memory is another astonishing number, as Cheyenne has 313,344GB of DDR4-2400 ECC single-rank memory and 224 IB Switches. Keeping all this cool is 28 water-cooled E-Racks across 14 E-Cells, making each bay weighing approximately 1,500 lbs.

Components of the Cheyenne Supercomputer

  • Installed Configuration: SGI ICEâ„¢ XA.
  • E-Cells: 14 units weighing 1500 lbs. each.
  • E-Racks: 28 units, all water-cooled
  • Nodes: 4,032 dual socket units configured as quad-node blades
