Hey ORNL since its obvious the Jaguar supercomputer is no longer needed, do you mind shipping it to me? I could use a new one. Oh and would you include a nuclear reactor to power it? Much thanks..

Crysis at 100,000 fps.

I wonder how much faster it could run it using LN2.

But can it play Crysis?

OMFG

Reading the following comments indicates how poorly the population handles pure analytical research

You have some claiming this will crack AES encryption easily and anothers claiming it is impossible

Neither side has the evidence to show either argument

If anyone here can claim that this computer is needed to break AES encryption, you might want to supply the sourcecode to the AES encryption to first prove that the encryption needs to be cracked in the first place

If you cannot prove that the encryption is not backdoored to begin with then you will never be able to prove that this computer is needed to crack AES
---------------
The other side claims that AES cannot be cracked with this computer and make that claim with the same lack of information
---------------
Making wild conspiracy claims based on a lack of evidence and then claiming the other side is the conspiracy nutt is the height of idiocracy

Both sides claim the other is the conspiracy theorist yet neither side has done the research necessary to prove a damn thing

If you ever read that this or any other computer has cracked AES or any other encryption, you must first prove that the encryption is not backdoored to begin with before you can show that the computer cracked jack shit

I am not the conspiracy wacko in this forum!

You people are

Dude~ Who cares? I mean, really? Why get all so worked-up? Shit.

I would wager that he gets worked up because of all the misinformation out there, and rightly so. I would bet that BJM either works in the security field or has a large passion for it judging by his other posts. As we so frequently see here passion drives a lot of the conversations here on MPC and if you know that people are posting inaccurate info on something you are passionate about you try to correct it. As for who cares, I guess I do as I am taking the time to respond. His posts are fairly accurate, whether you agree or not is entirely up to you.

Anyone else surprised to see Opterons in the spec sheet? I'm actually pretty proud for my favorite little chip company. It would have made sense to have a few 7970s in there, too. The teslas are better per-watt, but GCN is a beast at GPU compute when wattage is no problem. Would have been a good addition to kick in when heavier loads find their ways into the calculations such as. Calculating the growing adsorbtion of sunlight as a particular glacier melts away comes to mind. GPU code was probably written in CUDA, though.

Not surprising at all. If you look at most super computers around the world the opteron has been a favorite CPU for a while. Simply it scales better than the xeon when you are talking 1000+ nodes. And the price to performance ratio is in AMD's pocket not Intel's. Dollar per dollar you get more for an opteron. Xeons are faster but far more costly for that gain. This is nothing new. Ever since Sparc processors lost traction, the opteron gained traction.

the intel xenon would have cost them an arm and a leg. then space would have been wasted with the extra invisible cores.

Negative. The choice to use Opterons and not Xeons was slated from the get go. It had nothing to do with cost but with design and planning. The design architecture for Jaguar was founded on the AMD Opteron platform in 2005 and the decision was to continue the design evolution using the same CPU structure for Titan.

PS - Xenon is an element (part of the noble gases); Xeon is the name of Intel's server/workstation CPUs.

Kinda of surprised. I would thought they used a non x86 chip for supercomputers and/or servers.

Sorry if it sounds i'm being an ass. Maybe I am.

Who believes this TITAN is really crunching 'climate change' numbers? That shit is laughable. As if the last one hundred years of collected weather data is usable to predict the fucking future? How old is the planet... hundreds of millions of years?

This TITAN is a massive decoder ring for the NSA- good luck with your PGP and the rest of it. This thing can brute force any conceivable encryption protocol to date. When can it start on my neighbors WPA PSK?

Budman_NC

The Earth is actually thousands of millions of years old... like about 4.5 billion years.

The TITAN is not nearly capable of brute forcing AES encryption. All of the supercomputers in the world today together would take years to brute force a single AES key. They do use some supercomputers to "simulate" the possible decryption algorithms for various encryption schemes, but they do this to look for flaws in their encryption schemes so that they can fix those flaws in order to make their data more secure, not to break the security of other people's data (although if they did find a major flaw in a common protocol I wouldn't be surprised if they did use it to access other people's data, that's just not their main goal).

And of course the TITAN is being used to simulate weather data. How do you think we know that there was an ice age 100,000 years ago? Just because we didn't have a scientist sitting at a desk copying down temperatures 10,000 years ago doesn't mean we can't still figure out that data today. Ever heard of core samples? Or fossils? Carbon-dating? We have much more than 100 years of data. We have weather data from the beginning of Earth itself. The TITAN is being used to calculate the correlations and patterns between different aspects of this data so that we can better understand how weather works and make more accurate predictions about the future.

See, this is exactly what's wrong with most American's. Instead of reading an article like this and doing some critical creative thinking about it, how technology can help the human race progress, maybe doing some of your own research into the science behind this, and maybe even coming up with some potentially brilliant ideas of your own, you immediately jump straight to conspiracy theory and propaganda.

Good Lord I'm grateful to be Canadian.

AES was defeated long ago with a hacked ps3 running linux. it killed it in a months time. posting in a linux quarterly mag.

avatar

Cregan89

lol no it wasn't...

avatar

flyup

So you think that because we have core samples that indicate an ice age, TITAN can somehow predict the future. This massive machine is only as good as its worst programmer. Your Canadian fallacy is as misinformed as your crazy smoked meats you got up there.

Do Canadian's have Windows for Weather or something we Americans aren't aware of?

Dude, just STFU. You're embarrassing your country and giving people like Carolyn more ammo to hate America with.

I'm embarrassing my country: http://peterldg.tumblr.com/

hehehe.

Who the fuck is Carolyn and why should I care?

Andrew.Hodge

However you spell that. That was the word that my phone automatically chose. What the hell was the link? You take pictures? Blog? You have still failed to prove a point.

Andrew.Hodge

Love the little anti-American subrant at the end there. If you think flyup is a normal American, you have been spending your time around the wrong Americans.

Cregan89

I know it was a little uncalled for, it just drives me nuts when I read an interesting article about technology and then the "flyup's" of the world automatically jump to "NSA conspiracy!".

And ohhh I know that flyup isn't a "normal" American. I have plenty of intelligent American friends, relatives, and co-workers who would be thoroughly embarrassed of flyup. But while flyup isn't a "normal" American, he is extremely close to being an "average" American. I mean 46% of Americans don't believe in evolution! That is a downright terrifying statistic.

Considering these 46% of the American population get to vote for the President of the most powerful country in the world, their thought process not only screws over the USA, but it screws over the entire world, including Canada. And as such, I feel it is my civil duty to engage this 46% in some form of critical thinking, one at a time, for the sake of humanity.

avatar

Andrew.Hodge

That is a completely legitimate stance to take. Countries' politics are always intertwined when they're as close as America and Canada. What really gets me, though, is the anti-americanisim that runs rampant on the internet that pretty much consists of either "I hate you because its cool to where I'm from" or else jealousy rants. It wears on me, seeing people preaching their hate against america all over the internet. I have developed this knee jerk reaction lately because of this.

Carlidan

Don't blame Americans Cregan. Blame religion! It's not just Americans, I bet you have crazy religious Canadians who also believe the same shit as fly. Religion stops them to believe that Earth is billions of years old.

avatar

Cregan89

Yes of course Canada has their crazy religious people, what country doesn't... Ours just take up a significantly lower percentage of our population.

avatar

Carlidan

I can't disagree with that. :(

tony2tonez

They are already building that in Utah, but the public does not care to stop it. Goodbye to AES-256

Carlidan

Yes they are using it to predict climate change. You seem not to understand what they are predicting. You seem to think they are predicting weather everyday for the next 50 years. If you think that, then you don't understand science. What they are predicting how much the weather is going to go up by degrees in 1, 10, 20 years. They can do that by factors of data collect by past weather patterns, arctic glaciers disappearing, more tornadoes,earthquakes,hurricanes than the past, etc... They make a model of all of it in the computer. It crunches all that data and makes a prediction, with percentage of what the weather will be. Like say 70% the weather will go up 1 degree in the next 5 years. Or that 80 that state, the water level with go up 1 inch in the next 10 years. It's called predictions. And usual it's right. It's call math and science. But you seem not to understand that. :(
