Which is the fastest of all the fastest supercomputers?
wsippel t1_iwfy16v wrote
Frontier, the first supercomputer to exceed 1 exaFLOPS/s, almost three times as fast as number two. Powered by Epyc CPUs and AMD Instinct compute accelerators.
Here's the current list: https://www.top500.org/lists/top500/2022/11/

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.
wsippel t1_iwg3vqe wrote
It's a lot, but the performance per watt is actually really good, and that's what matters. It's the sixth most energy efficient supercomputer: https://www.top500.org/lists/green500/2022/11/
nexus1011 t1_iwg1krr wrote
Look at the 2nd one on the list.
29,000 almost 30k KW of power!
Zeraleen t1_iwg64o3 wrote
30k kW, that is almost 30MW. wow!
Gnash_ t1_iwgf457 wrote
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
calvin4224 t1_iwgfzlw wrote
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!
Ok-disaster2022 t1_iwid396 wrote
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.
calvin4224 t1_iwror1m wrote
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?
Gnash_ t1_iwgk22o wrote
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?

Yeah I think it was

Yea maybe, but can it run Crysis?
MattLogi t1_iwga7wo wrote
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
Catlover419-20 t1_iwgfacd wrote
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
MattLogi t1_iwguqiu wrote
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.
Contortionietzsche t1_iwgark3 wrote
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.
Dodgy_Past t1_iwgrgw5 wrote
I was selling sun servers back then and customers never considered power consumption.
Diabotek t1_iwgf8be wrote
Lol, not even close. 30,000 kW * 720 hours * kW price.
MattLogi t1_iwguf3a wrote
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.

Data centers are generally located specifically where they can get cheap power.

Wouldn’t they lease it though 🤔 Idk any company that outright buys a server

You’re probably right.

It's a cluster. I forget if they've published the official number yet but I want to say it was something like 256 racks of servers. I turned down a job there last year.

If you include distributed computing then Folding@Home is probably the fastest in the world with 2.43 exaflops of power since 2020.

If you want your mind blown you should look into quantum computers! They're insane! They can create time crystals, that's crystals that can change state without the need to add energy or loss of energy creating true perpetual motion! And with time crystals we might be able to create even faster quantum computers by using them as quantum memory.
And even though I have no idea what any of it means, I am excited because this is real life sci-fi stuff! There's a great mini-series called DEVS where they use a quantum computer and it's nuts they exists in real life.
And you might say "yeah yeah everyone has said there's new tech on the horizon that will change the world but it always takes way longer for anything close to be developed" but check this out: The IDEA of time crystals was thought up just 10 years ago, since then they have not just been proven to exist but we can create them and yeah deep dive into everything quantum computers are doing it's just speeding up exponentially every day!
bigtallsob t1_iwgosoo wrote
Keep in mind that anything that appears to be "true perpetual motion" at first glance always has a catch that prevents it from being actual perpetual motion.
SAI_Peregrinus t1_iwhcom7 wrote
Perpetual motion is fine, perpetual motion you can extract enirgy from isn't. An object in a stable orbit with no drag (hypothetical truly empty space) around another object would never stop or slow down.
A time crystal is a harmonic oscillator that neither loses nor gains energy while oscillating. It's "perpetual motion" in the "orbits forever" sense, not the "free energy" sense. Also has nothing to do with quantum computers.
pterofactyl t1_iwinoyy wrote
Well no because for that “no drag” space to exist, it would need to be in an imaginary world, so perpetual motion does not exist either way.
MurderDoneRight t1_iwh3wgv wrote
True, a perpetual motion machine is impossible according to the laws of physics. But time crystals are not a machine, it's an entirely new kind of exotic matter on par with supersolids, superfluids and Bose-Einstein condensates!
bigtallsob t1_iwh8ebm wrote
Yeah, but you are dealing with quantum funkiness. There's always a catch, like with quantum entanglement, and how despite one's state affecting the other regardless of distance, you can't use it for faster than light communication, since the act of observing the state changes the state.
MurderDoneRight t1_iwhacjs wrote
Yeah, like I mentioned in my first comment I don't really know anything so you may be right too. 😉
But I don't know, there's a lot of cool discoveries being done right now anyway. I did read up on quantum entanglement too because of this years Nobel prize winner in physics who used it to prove that the universe is not "real". How crazy is that?
SAI_Peregrinus t1_iwhc0ph wrote
Time crystals have no direct relation to quantum computers.
Quantum computers currently are very limited, but may be able to eventually compute Fourier Transforms in an amount of time that's a polynomial function of the input size (aka polynomial time), even for large inputs. That would be really cool! There are a few other problems they can solve for which there's no known classical polynomial time algorithm, but the Quantum Fourier Transform (QFT) is the big one. AFAIK nobody has yet managed to even factor the number 21 with a quantum computer, so they're a tad impractical still. Also there's no proof that classical computers can't do everything quantum computers can do just as efficiently (i.e. that BQP ≠ P), but it is strongly suspected.
Quantum annealers like D-wave's do exist now, but solve a more limited set of problems, and can't compute the QFT. It's not certain whether they're even any faster than classical computers.
I've made several enormous simplifications above.

Devs was an imperfect show, but good enough to be measured against one.
It deserved a bigger audience & should get a watch.
