Titan supercomputer displaces IBM's Sequoia as world's fastest

The U.S. Department of Energy's Oak Ridge National Laboratory (ORNL) is now home to the world's fastest supercomputer, according to the latest Top500 list. Aptly dubbed Titan, the Cray-built system knocked off IBM's Sequoia after only six months in the...

Perhaps intel should build a super computer running intel processor and built-in graphics and call it wintel super computer.

and nvidia should build its own calling it NV (because envy is owned by hp)

The worlds fastest computer runs off AMD!? I'd have lost that bet.
Titan is the "old" Jaguar supercomputer updated with Nvidia Tesla K20X co-processors. As for why Opterons are still used as opposed to Intel Xeon, this may provide some insight:
Incidentally, the Opteron processors used in the system are dual-chip CPUs based on the Bulldozer microarchitecture. We asked Sumit Gupta, General Manager for Tesla Accelerated Computing at Nvidia, why those CPU were chosen for this project, given the Xeon's current dominance in the HPC space. Gupta offered an interesting insight into the decision. He told us the contracts for Titan were signed between two and three years ago, and "back then, Bulldozer looked pretty darn good."
Titan - as in Titanic? Well good sail then!
Did you think that up all by yourself ?

I thought the Chinese had the world's fastest supercomputer. Or is that just the one with the loudest mufflers?
The Chinese used to have the fastest, but Titan has the new paint job that puts the Chinese to shame. I hear that the Chinese are looking to source a tail spoiler, some chrome rims and a good subwoofer, which should entail that they regain top spot.
If it's irony you want, then irony you'll get.. Did you know that "Megaupload's" seized files were hosted by "Carpathia's" servers?

Thanks, though I fear we've fallen short of the high bar that VitalyT has set
I think it was Satchel Paige that said, "don't look back, there's always somebody gaining on you".

It's such a rare and blissful thing when one reply works for two different quotes....

But, speaking of "supercomputers", I bought a Core i3-3225 with a Gigabyte Z77X-UD3H (ATX) board for $215.00 US. The i3 has the 4000 series graphics. My question is, "will that graphic chip supply 1080p porn to my TV without complaint, or any appreciable stuttering? I hate it when an IGP locks up in mid-shag....

What's low is the creators' imagination for the name. It's just as original as calling it "The Best Supercomputer". Google for Titan products, you'll find millions. Ironically, half of them did do the Titanic thing :)

Hah, well, it's more like it runs off Nvidia. The AMD processors are just there for a few minor tasks that the GPU still can't quite deal with well, so they obviously went with the cheapest option for that, instead of the highest performing :p

completely wrong actually, except for the cost saving, the main reason they went with AMD CPUS was because jaguar was AMD, and they were not going to need to switch out the boards. Anandtech had a very well done article about titan two weeks ago. The new CPUs have have 16 Cores per CPU(jaguar was 12, and the new ones are based off the new Bulldozer architecture), there are 4 cpus and 4 gpus per board. For most of what Titans doing at this time its still very CPU core reliant, but the GPUS will become more and more key as the researchers code it into there programing.
