back to article Supercomputers need standard shot glass to measure out juice

The biggest challenge in getting to the next level of supercomputer performance – Exascale – is the massive amounts of electricity these systems will consume. On a smaller scale, energy consumption also inhibits HPC installations. The problem isn’t just getting enough plugs from your walls to the grid; it’s also the cost of …

Perhaps they should get one of these new 'smart meters'

Apparently that will tell then where they can save power...

Not if it's running on one of the above to calculate the savings!

Units, units, units!

What's that in Hamsters?

Re: Units, units, units!

depends on how you are using the hamsters...

Option 1. Running in wheel

Option 2. Burning to generate steam

Hampsters (was Re: Units, units, units!)

Option 3. Glass cage, lines of coke(or other stimulant) on the floor, electrodes sprinkled through-out

The other 39 options

Or perhaps piezo floor tiles to generate /free energy/?

Locate in Montreal

Hydro Quebec makes power for about 1c/kwh, NewYork pays 5 or so, but if you want to attract new business in the province I'm sure they would cut a sweet deal. Quebec is already a leader in aluminium production.

interruptable...

Caterpilar make a number of large UPSes. We have 1.5MW of their backup units onsite at $orkplace and they get a lot larger than that.

Given the incremental cost over power conditioning the generation plant is trivial cost compared with cost of losing power (even on a 99.999% reliable power supply).

Getting rid of the MW once the computers have finished with it is another (expensive) issue.

Re: interruptable...

Perhaps they should locate them in a country like Sweden where district heating is very common, or Norway where it is becoming common, then all, or at least a lot, of the waste heat can be used for space heating and keeping pavements clear in the winter.

Re: interruptable...

The problem is what do you do with it in Summer?

You end up with a massive cooling plant that is shut down over the winter, when you have to heat it to stop it freezing up!

Summer? I take you don't know much about Scandinavia. It is now only 10 deg. C in the midle of June here in Norway 40km south of Oslo. And the cooling plant would not be shut down in the winter it would be used to transfer the waste heat to a district heating system via an industrial scale heat pump of the same sort that we use to pump heat out of the river here to warm up pavements to keep them ice free.

Re: interruptable...

Getting rid og MW? You just need a resistor with some fracking big cooling fins. I always wanted to buy one of those for the times when leccy spot prices go negative (Like Germany, Late night, Lots of wind),

Paris, 'cause she's hot, too.

The point is not to get rid of waste heat

The point is to use it to use the heat somewhere where the alternative would have been to use electricity or fuel to produce heat anyway. For example, by preheating water going into a district (or large building) water heating system. If you can use the heat produced by a supercomputer to "offset" the power use by another part of your building, then you are legitimately saving that energy, and can subtract it from the amount of power your data centre eats.
