On Tuesday, the US Basic Companies Administration started an auction for the decommissioned Cheyenne supercomputer, situated in Cheyenne, Wyoming. The 5.34-petaflop supercomputer ranked because the 20th most powerful on the earth on the time of its set up in 2016. Bidding began at $2,500, however its worth is at present $270,085.
The supercomputer, which formally operated between January 12, 2017, and December 31, 2023, on the NCAR-Wyoming Supercomputing Center, was a strong (and as soon as thought-about energy-efficient) system that considerably superior atmospheric and Earth system sciences analysis.
“In its lifetime, Cheyenne delivered over 7 billion core-hours, served over 4,400 customers, and supported almost 1,300 NSF awards,” writes the College Company for Atmospheric Analysis (UCAR) on its official Cheyenne information page. “It performed a key position in schooling, supporting greater than 80 college programs and coaching occasions. Practically 1,000 tasks have been awarded for early-career graduate college students and postdocs. Maybe most tellingly, Cheyenne-powered analysis generated over 4,500 peer-review publications, dissertations and theses, and different works.”
UCAR says that Cheynne was initially slated to get replaced after 5 years, however the Covid-19 pandemic severely disrupted provide chains, and it clocked in two further years in its tour of responsibility. The public sale web page says that Cheyenne lately skilled upkeep limitations because of defective fast disconnects in its cooling system. Because of this, roughly 1 % of the compute nodes have failed, primarily because of ECC errors within the DIMMs. Given the expense and downtime related to repairs, the choice was made to public sale off the elements.
With a peak efficiency of 5,340 teraflops (4,788 Linpack teraflops), this SGI ICE XA system was able to performing greater than 3 billion calculations per second for each watt of vitality consumed, making it 3 times extra energy-efficient than its predecessor, Yellowstone. The system featured 4,032 dual-socket nodes, every with two 18-core, 2.3-GHz Intel Xeon E5-2697v4 processors, for a complete of 145,152 CPU cores. It additionally included 313 TB of reminiscence and 40 petabytes of storage. Your complete system in operation consumed about 1.7 megawatts of energy.
Simply to match, the world’s top-rated supercomputer in the intervening time—Frontier at Oak Ridge Nationwide Labs in Tennessee—incorporates a theoretical peak efficiency of 1,679.82 petaflops, contains 8,699,904 CPU cores, and makes use of 22.7 megawatts of energy.
The GSA notes that potential consumers of Cheyenne ought to be conscious that skilled movers with acceptable gear will likely be required to deal with the heavy racks and elements. The public sale contains seven E-Cell pairs (14 whole), every with a cooling distribution unit (CDU). Every E-Cell weighs roughly 1,500 kilos. Moreover, the public sale options two air-cooled Cheyenne Administration Racks, every weighing 2,500 kilos, that include servers, switches, and energy models.
As of this writing, 23 potential consumers have bid on this computing monster up to now. The public sale closes on Could 3 at 6:11 pm Central Time in case you’re excited by bidding. However do not get too excited by photographs of the in depth cabling: Because the public sale web site notes, “fiber optic and CAT5/6 cabling are excluded from the resale bundle.”
