I could have used that for my H.264 recoding needs! :iagree: :smiley:

Titan will be used to develop more efficient engines, biofuels, [B]and model climate change.[/B]
With the amount of power that thing is consuming, it may just be responsible for climate change. :slight_smile:

Seriously though, that’s a mighty impressive piece of hardware.

According to another BBC article(http://www.bbc.co.uk/news/18033970):
“A focus on maximising performance per watt led Nvidia to take the unusual step of making the cores in its new Kepler architecture run about a third slower than their equivalents in its previous generation of chips.”

and

“Nvidia says that its technology will allow Titan to be more than twice as powerful as the current record holder- Fujitsu’s K Computer in Japan - and also more than three times as energy efficient.”

Yeah but.
Each Tesla GPU module has a TDP of 225W, and there is 18,688 of them in Titan, plus 18,688 CPU’s. That’s 4.2 Mega watts of power for the GPU’s alone.
Even if it is 3 times more energy efficient, that’s still a hell of a lot of power to consume.

True. However I believe there is still at least one nuclear reactor at Oak Ridge. Along with an experimental solar energy farm. In addition, and i could be wrong on this, but I think they can tap into the TVA power grid, so they can also utilize coal and hydroelectricity. So I’m betting they are covered on the power front.

It is a lot of power though.
