ORNL XT Jaguar uses over 45,000 quad-core Opteron's

Supercomputers are used in science and research to perform very complex calculations and simulations that are needed in scientific research. Research often involves modeling climate change and other projects.

The Cray XT Jaguar supercomputer installed at the Department of Energy's Oak Ridge National Laboratory (ORNL) was upgraded recently to increase its performance significantly. The supercomputer is now capable of 1.64 petaflops per second. A petaflop is quadrillion mathematical calculations per second.

The upgrade makes the XT Jaguar the first petaflop system in the world dedicated to open research. One of the first calculations achieved a sustained performance of more than 1.3 petaflops.

Dr. Raymond L. Orbach, the DOE Under Secretary for Science said in a statement, "Jaguar is one of science's newest and most formidable tools for advancement in science and engineering. It will enable researchers to simulate physical processes on a scale never seen before, and approach convergence for dynamical processes never thought possible. High end computation will become the critical third pillar for scientific discovery, along with experiment and theory."

The upgrades to the supercomputer were a four year project that the DOE says came in on time and on budget. The sustained petascale performance the computer achieved isn’t the first time an ORNL supercomputer has set records for performance. In 1998, another ORNL team was the first to achieve sustained terascale performance for science.

The updates to the Jaguar supercomputer included the addition of 200 Cray XT5 cabinets to the existing 84 XT4 cabinets used in the Jaguar machine. The computer uses over 45,000 of the latest AMD quad-core Opteron processors and has 362 terabytes of memory and a ten petabytes file system.

In June, the fastest supercomputer in the land was capable of 1.026 petaflops.

Always love when the super computer gets more powerful.

Anyone know what build of an OS it uses?

I was JUST about to post a comment asking for NOTHING about Crysis. I thought this dead horse was beaten to a pulp already. Apparently, SOMEONE thinks we need horse purée.

Haha, yes, but it might live so long, since the game still demands pretty massive GPU power to run in it's full glory.

That's undoubtedly the next revision in the works. It takes a long time to design, budget and build a petaflop machine, so they aren't right on the bleeding edge of chip tech. The earlier versions of Intel CPUs still were less power efficient than Opterons in general, and that's why they were the darling of the HPC crowd. Power use and heat dissipation are the real prime concerns of these giant machines, not simply pure CPU speed.

The Opterons are also very well known for their scaling performance.

The opterons were probably the best thing around when they were in the design phase of this thing...aka 2-3 years ago.

The Opterons are STILL the best for this system...
While Nehalems will (hopefully) support NUMA architectured systems like this, the C2D does not.
It will take a few years before we even see Nehalem NUMA systems because of the testing that will be required, followed by the design and build.

Can you imagine 45,000 Core2 Quads sharing a 1333MHz FSB ;)

Opteron is (was?) the HPC darling for power-performance level which was mainly due to the incredible scaling offered by its hyper-transport architecture. (also attractive was that HPC makers built machines with the ability to nearly double performance by 'simply' swapping out say older Dual Core Opterons for Quads in the future.)

i7's new bus system should get Intel back into the HPC game in a big way I'd imagine.

Horse purée? Is there a pulpless version? I've been thinking about getting a juicer, but I hate pulp in my horse juice.

For some reason I didn't expect a Crysis comment, that will teach me.

I doubt the overhead due to emulation will be too high though. Even 50% overhead will probably be acceptable when you have terrabytes of memory.

Go figure haha.

It would be quite awesome I think to have whatever setup they use as an available install for home computers to see what they could process... sort of like Folding @home but setup your own instructions as well.

Your home computer would be worthless with it. It is setup for true parallel processing between all those processors with minimal loss. So, unless you have a serious multi-processor setup (at least triple digits), no go.

Doesn't mean you can't grab a stripped down Linux (Gentoo would be good) and enjoy the efficiency and Fold@Home.

Ahh see I have that covered. I have 200 PII proccessors. (okay not really)

I think it would just be cool to see what they use and be able to use it as well, that way if you are in college in a field that may work with the system, you can experiment on what would work well and what wouldn't.

Not a damn Intel processor no where near this monster. I just read that article again and mention of Intel POS processors

Awesome, do you think...

That a computer like this will provide enough statistical data to the Anti Nuclear Power nitwits to curb their worries and show them it is the future? ;)

Impressive processing power nontheless. I hope they put it towards something useful like I mentioned above.

are you saying that you made your decision about nuclear based on data? meaning you only made the decision once you saw the "data"

Well, technically nuclear is now, I would lean toward fusion being the future, ha.

The thing is, the future is inevitable. It will happen. Time will progress. Why deny what will occur later when you can accept it now? ;)

They measured it's acceleration?

The supercomputer is now capable of 1.64 petaflops per second. A petaflop is quadrillion mathematical calculations per second.

So they measured petaflops per second, eh? That would be quadrillion mathematical calculations per second^2, I guess? That's impressive accleration, maybe?

Sorry, gotta go - I've got to put my PIN number into the ATM machine.....

I liked the questions asking; How much energy does 1.3 petaflops use just so the DOE can calculate much energy they can save?

Note that these are published tests, usually by the builders with the owners' permission. I can think of some 'owners' that may not want to publish, or even acknolowedge that their system exists
