I wonder who buys these. Crypto miners? My institution would make it nearly impossible to buy a secondhand supercomputer.

Recyclers.

any I've dealt with definitely wouldn't touch the 'you need to hire professional movers costing you $10k's of dollars to get it out of the facility' stipulation - they seem to prefer the 'where's the location of the storage shed' situation.

I wonder what the point of liquid cooling such a system was. Were they pressed for space?

Built in a bunker under a mountain, so reduced airflow, plus need to hide heat signatures from outside surveillance?

Also, likely they had infrastructure available, from the nuclear power they use.

There's a whole sub-industry of people bidding on government auctions in order to part out the stuff. I'd be pretty surprised if the whole cluster got reassembled. But people on a budget will buy those compute nodes, someone trying to keep their legacy IB network will snap up those switches, the racks, etc.

For those curious, Cheyenne is a supercomputer from 2016/2017 that launched on the 20th spot in the top500 super computers. It was decommissioned in 2023 after pandemic lead to a two year operation extension.

It has a peak compute of 5.34 petaflops, 313TB of memory, and gobbles 1.7MW.

Doesn't matter what conductor you use to move heat, the same amount of energy will have to be dispersed. And watercooling just implies more intermediate steps between the heatshield of the die and air. So I don't believe the heat signatures can really be helped.

This is a weather supercomputer, not a defense one.

r/homelab will have a field-day getting those nodes up, some people will want just one for practicality, some people will want at least a couple and a IB switch just for the novelty of it.

I can't imagine anyone from r/homelab has an SGI 8600 E-cell laying around that they could slap these blades into.
