Winner looking at his electricity bill:

Hey, I have worked on this exact machine before, neat to see they are finally decommissioning it. It would be a terrible purchase to actually use these days though, for the cost of moving and deploying it you could rock a few Hopper or Grace clusters that would outperform the cluster for less than half of the operating overhead.

I fully expect it to get parted out, the actual components would be far more useful on their own as cheap homelab systems, and would be a much better ROI versus using it as is. This thing is water cooled, just the plumbing would be a nightmare to deal with if you aren't set up for it, and if you are you would be better off going with a modern architecture anyway.

What were you using it for?

[–] [email protected] 13 points 6 months ago (1 children)

We were running meteorological models mostly, but I did have a colleague that was trying to use it to predict wildlife migratory patterns using topographical mapping. It was batched out on a few projects at any given time while I was there, it was essentially timeshares between a few different research departments.

Do you mean to tell me you didn't run Doom on that?!

[–] [email protected] 3 points 6 months ago

Haha, unfortunately no. None of the blades used a windowing system, so we technically wouldn't have been able to as there is no graphical output (well, the IPMI controllers could have, but that's kind of cheating). Although, as I'm thinking about it... We probably could have run it over ASCII graphics in a terminal... Man, that was a bit of a wasted opportunity, weather modelling is boring as hell.

Power consumption: 1.7 MW

I hope it stays decommissioned. We're burning up the planet too fast already, and old computers tend to be far less efficient than modern ones.

Pop up a solar farm and you are good to go, baby!

[–] [email protected] 12 points 6 months ago (2 children)

Yeah just need 10Mw+ of solar and like 40mwh of batteries to power it 24/7

Yeah, I saw the 4Mil BTU on another page, that's a lot of heat output

The specs seem to be just enough to run a Minecraft server that doesn't freeze when one player explores new chunks.

[–] [email protected] 23 points 6 months ago (1 children)

no use, minecraft server is single threaded. it won't hit 20TPS in an even slightly complex world no matter how much compute you throw at it

[–] [email protected] 12 points 6 months ago

Yeah but you can put the whole world on RAM disk.

Damn that’s crazy. When I was just out of college I built the touchscreen web app that promoted this thing in the lobby of UCAR. Looks like it’s still running for now: https://hpctv.ucar.edu

[–] IdiosyncraticIdiot 11 points 6 months ago (1 children)

That is a really cool resume item, ngl

Do you mind me asking the languages/frameworks backing it? (e.g. JavaScript/Node)

[–] [email protected] 10 points 6 months ago

Thanks! It was a Python backend that the data science team at UCAR built and a Vue.js front end.

[–] [email protected] 4 points 6 months ago

Neat application. Looks fun :D

[–] [email protected] 40 points 6 months ago

The price will only be exceeded by the power bill for the electricity needed to run it.

[–] [email protected] 36 points 6 months ago (2 children)

This thing is basically the size of my apartment.

Which means I have room! How much?

[–] [email protected] 4 points 6 months ago

Currently around $51k, reserve not yet met. Buyer responsible for transportation and cabling not included, fyi.

Who wants to go in with me on this?

New Lemmy server?

[–] [email protected] 21 points 6 months ago (1 children)

Let's turn it into a Lemmy server.

Killing a fly with canon there, aren’t you?

I call it future proofing.

I hope Matthew Broderick buys it.

And then programs it to play a nice game of chess

No, let's play Global Thermonuclear War

It's kind of lame that they need to junk the entire apparatus after only a decade. I get that processor technology moves on apace but we already know it does that so why doesn't a universal architecture exist where nodes can be added at will?

[–] [email protected] 26 points 6 months ago

It's more of an operating cost issue. It's almost decade-old hardware. It was efficient in its day, but compared to new hardware it just costs so much to run you would be better served investing in something with modern efficiency. It won't be junked, it will be parted out. If you are someone that wants a cheap homelab with infiniband and shitloads of memory you could pick up a blade for a fraction of what it would otherwise cost. I fully expect it to turn into thousands of reasonably powerful servers for the prosumer and nerd markets instead of running as a monolithic cluster.

A decade is a lifetime in technology. Moore's law had just ended when this was put together.

If you have too many "slow" modes in a super computer you'll hit a performance ceiling where everything is bottle necked by the speed of things that are not the CPU: memory, disk for swap, and network for sending partial results across nodes for further partial computing.

Seems like it's cheap to start the bidding at $2500 but the cheapest thing is probably the initial purchase price after moving it, buying the needed cabling, and electricity bills.

[–] [email protected] 23 points 6 months ago* (last edited 6 months ago) (1 children)

I bet manpower costs are significant as well. How many people are needed to run this thing? You probably need engineers with an esoteric set of skills to put it back together and manage it which would not be cheap.

Edit: I looked it up, it is running SUSE Enterprise Linux, so maybe management isn't as specialized as I expected.

Whoever buys it will most likely just part it out and sell it on ebay.

[–] [email protected] 14 points 6 months ago

It's all Broadwell Xeons. Sure, there's 8000 of 'em, but after you factor in purchase price, moving and storage costs, time spent parting out nodes, shipping costs, etc... I think you'd have a hard time breaking even, and for an end user you can get like 4x the FLOPS per socket at half the power consumption with current server CPUs.

No. But it will run NetBSD 😇

[–] [email protected] 7 points 6 months ago (2 children)

I'm guessing that it can run multiplayer Doom with ray tracing turned on.

I upvoted cause obligatory joke but there is a map that has like 100k enemies in it, I would like to try it out.

Please don't let crypto bros touch this

[–] sugar_in_your_tea 7 points 6 months ago

No need to worry, it'll have a terrible hash rate.

[–] [email protected] 17 points 6 months ago (1 children)

Just might be powerful enough for SolidWorks not to crash

[–] [email protected] 5 points 6 months ago

Not if you're running Monte Carlo

[–] [email protected] 14 points 6 months ago (1 children)

TIL that Silicon Graphics still exists...

[–] [email protected] 3 points 6 months ago

It doesn't. Bought by hpe.

[–] [email protected] 12 points 6 months ago

Let's just hope that it isn't bought up by Bitcoin miners . . .
