Reply to comment by wsippel in AMD Now Powers 101 of the World's Fastest Supercomputers by Avieshek

21,000 kilowatts of power. That's a lot, right? I read a story recently about a company that bought a Sun Enterprise 10000 server and an executive shut it down when they got the electricity bill.

Look at the 2nd one on the list.

29,000 almost 30k KW of power!

30k kW, that is almost 30MW. wow!

My Factorio factory only consumes 9 MW and I had to build 3 nuclear reactors, just to keep the power up at night. That’s one big supercomputer

irl a nuclear Generator has around 1 GW (1000MW). But 30MW is still about 6 Land based Wind turbines running at full load. It's a lot!

Physics wise you can run a GW reactor at 30 W and it will essentially last forever from a fuel standpoint, just the turbines and such have to re engineered to that lower output.

But there are smaller reactors. I believe for example the Ford class supercarriers run on 4x250w reactors.

I don't think that's how nuclear fission works.

Also, 4x250 Watts will run your kettle but not a ship :P

So the guy above a lying little shit or?

Factorio is a video game, did you really think I went out and built 3 reactors all by myself

also was the uncalled for insult really necessary?

What’s it power draw? Isn’t something like 30000 kWh only like $3000 a month? Which sure isn’t cheap but if you’re buying these super computers, I feel like $3000 is a drop in the bucket for them

Edit: yup, made a huge mistake in calculation. Much much larger number

Nono, that means 30000kWh is for 1h of operation. For one month of 24/7 at 30 days you‘d need 21.600.000 kWh or 21.600 mWh, or 2.741.040€ at 12,69ct/kWh. So $2.75M if Im correct

Yeah I messed up! I was think W as I do the calculation a lot with my computers at home so I always divide by 1000 to get kWh. Like you said this is 30000kWh! Oof yeah that’s a big bill.

True. Frontier is for the US department of energy right? The company that bought the E10K probably was not. AFAIK the E10K requires a 100 amp power line and back in those days (late 90’s) I don’t think performance per watt was a thing they worried about, could be wrong though.

I was selling sun servers back then and customers never considered power consumption.

Lol, not even close. 30,000 kW * 720 hours * kW price.

Oooo yeah I did a major mistake in calculation. I’m so used to calculating W with home computers and dividing by 1000 to get my KWH…this is 30000KwH! Ooooof! Yeah that’s a huge bill. Makes a lot more sense now lol

Diabotek t1_iwh5jxx wrote

Yeah 30000kW is an insanely massive number. The amount of power required to run that for an hour, could power my stack for 7 years.

It’s easy to power when you’re oak ridge and have your own nuclear power plant.
