Japan Builds World's Fastest Computer

claylikethemud writes "The New York Times reports that Japan has built the world's most powerful supercomputer from "640 specialized nodes that are in turn composed of 5,104" NEC processors. The machine boasts the computing power equivalent to the 20 fastest American supercomputers combined, and with a top speed of 35.6 teraflops, outpaces the next fastest machine, the ASCI White Pacific, by more than factor of five. Applications include climate modeling, global warming prediction, and other non-weapons research."

Did anyone see this coming?

With all of the supercomputer posts on /. recently, I've seen a lot of talk about the various ASCI projects in the works by IBM and others. No one even mentioned this before. I'm glad to see that someone is building supercomputers for reasons other than nuclear weapons research though.

For some reason Japan isn't all that keen on nuclear weapons.

Interesting comment from the SJ Mercury

The accomplishment is also a dramatic statement of contrasting scientific and technology priorities in the United States and Japan. The Japanese machine was built to analyze climate change, including global warming, as well as weather and earthquake patterns. The United States has predominantly focused its efforts on building powerful computers for simulating weapons.

What surprises me is that this is the first we (Slashdot readers) have heard about it. There have been several headlines saying 'new supercomputer planned' with a story 'it will be quite fast, and finished in 2004'... but this new world's-fastest-computer just suddenly appeared without being preannounced.

Are any of the supercomputer projects in the pipeline expected to be faster than this?

That is probably why they don't have a military (I think they now have a token military but not a real one)

Actually, Japan has one of the largest military budgets in the world. They call their military the `Self Defense Forces', but it's the real thing, with big ships, tanks, fighter jets, and all that good stuff. No nukes though.

The US military budget is SO high, because when we go to war, we want to destroy weapons and remove evil doers with surgical precision. All the while making the locals love the US.
The US ideally would go to war where only weapons ould be destroyed and noone would get killed.
To acieve this goal our weapons have to be extremely high tech.
Oddly enough it's value of all human life, both ours and the people in the region we're fighting that makes our budget so huge.

Canadians of course!
You never know when some pesky Canadians on a training exercise in Afganistan will suddenly turn their weapons on an American F16.

So when does a computer...

...become a huge goddamned distributed-network-in-a-room?

Re:Non Weapon research??

[SuiteSisterMary]

The Japanese are only able to maintain a defensive force, not an army, so even if it was weapons research, it would only be for use in self defense.

Well, American policy has always been that it's nukes are purely defensive weapons (like the Peacekeepers) so the argument could be made..... Oh, I forgot. What's OK for America isn't OK for any other country.

Like that would do anything...

Okay, so then the Japanese complain about us dumping. Then what? Let's say they win in WTO hearings. How nice for them. Then the US just ignores it. Why? Because we can. What real punishment can the WTO provide?

The WTO is totally powerless, especially against the US. The only thing it provides is a common forum for working these issues out and for establishing a sort of trade best practices. But when you get right down to it, trade disputes are settled as they always have been, either through discussion, or through various embargoes, tariffs, etc. The WTO may add some legitimacy to a particular countries use of some tariffs, etc, but overall it doesn't provide any significant sanctioning ability.

That's the funny thing with all of the world governmental bodies. They have no real power, they mostly just serve as negotiating platforms. The real power continues to be held by individual nations and there's no evidence that they'll be giving up that power anytime soon.

Re:You do not know what you are talking about

[JabberWokky]

First off, it was a single line comment only semiserious. Second, you say I don't know what I'm talking about, and you quote an article (as you put it, "I like to cut and paste") that contains:

Nuclear weapons are the most sensitive issue in Japan, Japanese people are strongly against it. Since the nuclear accident in Ibaraki Prefecture in 1999, the most serious nuclear leakage accident, Japanese citizens have lost confidence about nuclear industry, they asked governments to reduce or stop nuclear power plant construction.

So how, exactly, do I "not know what I'm talking about"? --
