Cray supercomputer named world's fastest

Nov 12, 2012
A Cray supercomputer at the US government's Oak Ridge National Laboratory was named Monday the world's fastest, overtaking an IBM supercomputer at another American research center.

A Cray supercomputer at the US government's Oak Ridge National Laboratory was named Monday the world's fastest, overtaking an IBM supercomputer at another American research center.

The ranking released by researchers from the United States and Germany found that Titan, a Cray XK7 system installed at Oak Ridge in Tennessee, achieved 17.59 , or quadrillions of calculations per second.

Titan, which gets funding from the US Department of Energy, is used for research in energy, climate change, efficient engines, materials and other scientific research.

Titan knocked the IBM Sequoia at the Lawrence Livermore National Laboratory in California into second place. It could only manage 16.32 petaflops.

Rounding out the top five were Fujitsu's K computer at the Riken Advanced Institute for in Kobe, Japan; an IBM /Q system named Mira at the Argonne National Laboratory in Chicago, and another IBM BlueGene/Q system named Juqueen at the Forschungszentrum Juelich in Germany.

Researchers said 251 of the 500 systems were in the United States, with 105 in Europe and 123 in Asia, including 72 in China.

Intel provided the processors for 76 percent of the systems while AMD was used in 12 percent and IBM in 10.6 percent.

The announcement came from the TOP500 list compiled by the University of Mannheim, Germany; the Lawrence Berkeley National Laboratory and the University of Tennessee.

It's a shame the climate change whores would waste the time/expense of such a marvelous machine.

is used for research in energy

Don't be fooled. When the DoE researches 'energy' we're talking research into maximizing yield of fission/fusion warheads.

I live in Perth, Western Australia & am on the periphery of the discussion re AGW, we've had significant changes over the last 30 years especially sea level as have my friends who travel to Tuvalu
http://en.wikiped...i/Tuvalu
They have been concerned with sea level rises since 1970's

Try try to understand, the earth is essentially a closed system in respect of atmospherics ie. Gases, fluids and heat.

I know its hard for you to understand & appreciate that the release of so many hundreds of billions of tonnes of CO2 over the course of the last 200 plus years has resulted in a small rise in sea level & temperature which has accelerated over the last 50 years.

When you do, just the basic physics, you very soon realise the huge capacity of water to soak up heat causes all sorts of discontinuities whilst heat load reaches different equilibria, not least of which is expansion of water & greater glacial runoff.

Wakeup.


@ Mike

I have lived through too many enviro-scams to ever believe in AGW. There are too many dollars at stake, too many research-whores trying to capitalize on funding; too many shysters at the top flying their private jets all-the-while preaching to us little people to reduce our lifestyle, to reduce our dreams and aspirations - Hell, they even chastise Chinese people for wanting to own an automobile!

AGW is a shady, profit-driven industry. It's leaders are proven untrustworthy and their scam relies on and promotes social class division. AGW "researchers" are 100% on the payroll in some form. AGW is funded by taxes collected by heavy-handed governmental force from people who can least afford it.

All proposed "solutions" to AGW will be borne by a consumer base least able to afford it. Meanwhile the (AGW) industry leaders get rich - exactly the financial scenario liberals detest.

I agree someone needs to wake up, but it ain't me.

ScooterG, lmao you were crying about people infringing on your right to be racist. How about you try civility and you might get some back.

Racism in and of itself is not illegal in America. If an American chooses to hate a particular race, that's their business - butt out.

You are clearly confusing those that can or might or do, in some way, exploit a (range of) scenario(s) VS probabilistic apparent causes of such scenario, your rhetoric similar to McCarthy era in USA, much vitriol & complaint but negligible actuality.

I recently met a meteorologist who came to Perth, Western Australia only about 5 years ago from overseas who had made up his mind AGW was unlikely & one piece of 'evidence' he pointed to was the minimal rise of sea levels at our Swan River estuary.

I pointed out he has forgotten about the rotation of the earth at 1000mph or so will mean much higher comparative sea level rise nearer the equator. He had time to check this with industry associates overseas such as in India, Africa, Philipines etc

Suffice it to say, his classic view of his science precluded consideration of pecuniary factors which show sea level rises at the poles will be substantially reduced in comparison with the equator.

He now accepts AGW & its rise.

I am a sceptically of AGW. However I don't subscribe to the whole vast conspiracy behind all of the AGW research. (Granting some of the research and researchers have been piss poor.)

The financial motive to skew the data in favor of AGW just isn't there. If it was a matter of spending money to achieve a desired result it defies logic to assume someone would spend more to slew data than the energy companies. Look at the financials from just the big oil companies Dutch Royal Shell, Exxon Mobile, Chevron, Tesoro, etc. If money is the motivation they combined could literally provide hundreds of billions of dollars in funding.

I accepted AGW right up until that boson at Penn State got outed for flat out lying and hiding data that was counter to AGW. That is NOT how scientific research is conducted. That is how propoganda is produced, then the real credability buster was when they found that he hadn't acted improperly after an investigation?

That said my real issue is with the models they use to simulate global climate. They ignore factors like aerosols (we don't know if they are net contributors or mitigators) and all of them fail miserably when it comes to accurately portraying past changes to global climate. Why then is it assumed they will do a better job predicting shifts in the future?

I do strongly believe we need to stop polluting the planet with CO2. Ocean acidification is very real our species gets a great deal of our food from the ocean and the oceans also produce more oxygen than all the trees and shrubs on land. That IMHO is a far bigger threat to our species than us turning the earth into Venus with our SUV's.

Whats the point, its also not illegal to be stupid and not illegal to bring up pointless associations about stupid and ignorance ?

One wonders what you are achieving by pointing to yourself in this way !

@dav_daddy
The situation is far more complex than that, just because AGW is accepted by the bulk of scientists in the field doesnt mean there arent one or two who are incompetent in respect of intellectual property and its misuse. There are unfortunate commercial pressures some feeble individuals are susceptible to no matter where the truth lies.

To change ones mind on the whim of an incompetent tactic doesnt change the bulk of evidence, to arbitrarily do so against prevailing evidence is idiocy or extreme ignorance of science, we are on a science forum arent we, we dont expect too many people here to be ignorant and starting using this forum as form of unthinking chat.

Liberals abhor anyone (especially Christians) who would impose their moral and ethical beliefs on others, yet they (libs) are the first to condemn anyone who they think might be a racist.

Liberals judging the judgmental - LOL - the epitome of hypocrisy.

And I retract my previous post regarding your civility.
