The Titan's Overthrown. Tianhe-2 Supercomputer New #1

The National Supercomputer Center in Guangzho, China, will host the the world's fastest supercomputer by the end of the year. The Tianhe-2, English: "Milky Way-2", is capable of nearly double the floating-point performance of Titan albeit with slightly less performance per watt. The Tianhe-2 was developed by China's National University of Defense Technology.

Comparing new fastest computer with the former, China's Milky Way-2 is able to achieve 33.8627 PetaFLOPs of calculations from 17.808 MW of electricity. The Titan, on the other hand, is able to crunch 17.590 PetaFLOPs with a draw of just 8.209 MW. As such, the new Milky Way-2 uses 12.7% more power per FLOP than Titan.

Titan is famously based on the Kepler GPU architecture from NVIDIA, coupled with several 16-core AMD Opteron server processors clocked at 2.2 GHz. This concept of using accelerated hardware carried over into the design of Tianhe-2, which is based around Intel's Xeon Phi coprocessor. If you include the simplified co-processor cores of the Xeon Phi, the new champion is the sum of 3.12 million x86 cores and 1024 terabytes of memory.

... but will it run Crysis?

... if someone gets around to emulating DirectX in software, it very well could.

That's all fine and dandy - but do you what happened 44 freekin' years ago? ...we put a man on the moon..since then

How can you be #1 when it won't be online until the end of the year? Doesn't it have to be functional NOW to win NOW? I'm confused.

"Tianhe-2, or Milky Way-2, will be deployed at the National Supercomputer Center in Guangzho, China, by the end of the year."

By this logic, Maxwell cards are the fastest on the planet now...But um...They're not out until Next year. But they're the fastest dang it...LOL. It may be 2yrs ahead of schedule but it's about 6 months late to make a JUNE list right?

Yeah that confused me a bit too... but here's the thing: it has *been* online and benchmarked. It is not setup in its final location with its optimal networking and cooling configuration, etc., and as such will not be used until sometime before the end of the year. But, it was benchmarked.

AFAIK it did manage to secure a spot on the June list, though I don't know if it was #1 (as not all the cores were online for the benchmarks and rollout, there is also more programming efficiency work to be done to try to reach the theoretical peak performance level). It will eventually be moved to its final location once everything has been tested out. It will get a fancy new liquid cooling system in the final location as well :).

Can you run a minecraft server on it?

June 27, 2013 | 12:21 PM - Posted by Scott Michaud

Yeah, but that would be a bit of a waste. Minecraft Servers are only *barely* threaded.

Now if you want to run about 64,000 Minecraft servers, then this computer will be *amazing*. : D

Apparently we need a 1 Exaflop Supercomputer just to accurately predict the weather forecast. I doubt even that'll happen when we get to 10 or 100 Exaflops. Playing with so much raw horsepower is nice, but in reality what is all of this really accomplishing?

I'd be more curious to know of studies and things supercomputers are doing on a regular basis other than the known fact they're going to keep increasing in power every 6 months. People once questioned the F@H and what it was really doing for science, now F@H is much more open about it. Same needs to be said for supercomputers. Can they be justified? A vast amount of them are paid for by tax payers, regardless of nations, people should be able to see progress other than the, "We're #1!" factor.

A lot of them are being rented, for a very large fee as you might imagine, by the hour-or-whatever to science teams and what-have-you.

Because, some times, you just really want to know all the eigenvectors of a gigantic matrix.
