World's Fastest Supercomputer Is "A Souped-Up PlayStation 3"

The public got its first glimpse at the world's fastest supercomputer on Monday, a petaflop-capable machine described by an IBM executive as a "souped-up Sony PlayStation 3."

Roadrunner, developed by engineers from the Los Alamos National Laboratory and IBM Corporation, is twice as fast as IBM's Blue Gene computer, which is itself three times faster than any other supercomputer in the world. The system weighs 500,000 pounds, according to a CNN report, takes up 6000 square feet and uses 6948 dual-core processors, 12,960 cell engines, 57 miles of fiber-optic cable and 80 terabytes of memory. The whole thing costs $100 million.

Yet much of the technology behind all that power has been evolved from videogame consoles. David Turek, vice president of supercomputing programs at IBM, described Roadrunner as "a very souped-up PlayStation 3" in some ways, adding, "We took the basic chip design (of a PlayStation) and advanced its capability."

In both testing and real-world applications in classified nuclear weapons work, the computer achieved "petaflop" speeds, breaking the 1000 trillion operations per second mark. Turek called the performance "a huge and remarkable achievement," and said that only two years ago there were no actual applications in which a computer reach even 100 teraflops, only one-tenth of Roadrunner's speed. Despite its early work with nuclear stockpiles, Turek predicted the computer would have a wide-ranging impact in the future. "The technology will be pronounced in its employment across industry in the years to come," he said.

I bet that computer could play crysis with the graphics set to very high. but seriously, stop giving the PS3 credit, we don't give henry ford credit for the cars that are out today, even though they are improved on his design. Besides it uses THOUSANDS of improved ps3 proccessors

Actually, most people do give credit to Henry Ford for the modern automobile. Although I do agree that calling it souped-up PS3 is a bit of misstatement. The Cell was designed primarily for the PS3, but multi core processors have been around for years.

Petaflops, huh? Ignoring the incredible hilariousness of that word, that's damn impressive.

Roadrunner - Four PS3's duct-tapped together.

Ahem, I can't agree with the phrase "a very souped-up Playstation 3"... by my math, it's (12,960/3) or 4320 souped-up PS3s hooked up to several miles of cabling and some other doohickies.

I'd heard of at least one university's computer science lab buying up batches PS3s and clustering them into a Linux supercomputer when the budget wouldn't cover a more conventional supercomputer purchase... Roadrunner takes this to entirely new levels, though, and my hat is truly doffed to their bloodymindedness.

I bet it can't run Crysis on full.

"A Suped up Playstation 3" Good job IBM now go get that money Sony's paying you.

It makes sense that they'd actually be able to do something useful with Cell, though. After all, being the people that built the damned thing, they're the only ones who know how to effectively program for it.

Device sounds awesome. Must be where they stole the Internet from in Live Free or Die Hard. Also good to know that petabytes is what comes after terrabytes.

Funny how the 6,948 dual core Opterons don't get a mention (by name) in most sources I've seen. Clearly Sony have more to spend on their marketing than AMD.

The Opterons are being used as the CPUs in the machine, while the Cells are utilised as Maths Co-processors as far as I can tell.

Press Release
Armonk, NY - 09 Jun 2008: In 2006, the Department of Energy's National Nuclear Security Administration selected Los Alamos National Laboratory as the development site for Roadrunner and IBM as the computer's designer and builder. Roadrunner, named after the New Mexico state bird, cost about $100 million, and was a three-phase project to deliver the world's first "hybrid" supercomputer - one powerful enough to operate at one petaflop (one thousand trillion calculations per second). That's twice as fast as the current No.1 rated IBM Blue Gene system at Lawrence Livermore National Lab - itself nearly three times faster than the leading contenders on the current TOP 500 list of worldwide supercomputers.

* Roadrunner will primarily be used to ensure the safety and reliability of the nation's nuclear weapons stockpile. It will also be used for research into astronomy, energy, human genome science and climate change.

* Roadrunner is the world's first hybrid supercomputer. In a first-of-a-kind design, the Cell Broadband Engine® -- originally designed for video game platforms such as the Sony Playstation 3® -- will work in conjunction with x86 processors from AMD®.

* Made from Commercial Parts. In total, Roadrunner connects 6,948 dual-core AMD Opteron® chips (on IBM Model LS21 blade servers) as well as 12,960 Cell engines (on IBM Model QS22 blade servers). The Roadrunner system has 80 terabytes of memory, and is housed in 288 refrigerator-sized, IBM BladeCenter® racks occupying 6,000 square feet. Its 10,000 connections - both Infiniband and Gigabit Ethernet -- require 57 miles of fiber optic cable. Roadrunner weighs 500,000 lbs. Companies that contributed components and technology include; Emcore, Flextronics, Mellanox and Voltaire.

* Custom Configuration. Two IBM QS22 blade servers and one IBM LS21 blade server are combined into a specialized "tri-blade" configuration for Roadrunner. The machine is composed of a total of 3,456 tri-blades built in IBM's Rochester, Minn. plant. Standard processing (e.g., file system I/O) is handled by the Opteron processors. Mathematically and CPU-intensive elements are directed to the Cell processors. Each tri-blade unit can run at 400 billion operations per second (400 Gigaflops).

* The machine was built, tested and benchmarked in IBM's Poughkeepsie, N.Y. plant, home of the ASCI series of supercomputers the company built for the US government in the late 1990s. IBM's site in Rochester, Minn. constructed the specialized tri-blade servers. Software development was led by IBM engineers in Austin, Texas and by researchers in IBM's Yorktown Heights, N.Y. research lab. Roadrunner will be loaded onto 21 tractor trailer trucks later this summer when it is delivered to Los Alamos National Lab in New Mexico.

* Roadrunner operates on open-source Linux software from Red Hat.

* Energy Miser. Compared to most traditional supercomputer designs, Roadrunner's hybrid format sips power (3.9 megawatts) and delivers world-leading efficiency - 376 million calculations per watt. IBM expects Roadrunner to place among the top energy-efficient systems later in June when the Official "Green 500" list of supercomputers is issued.

* IBM is developing new software to make Cell-powered hybrid computing broadly accessible. Roadrunner's massive software effort targets commercial applications for hybrid supercomputing. With corporate and academic partners, IBM is developing an open-source ecosystem that will bring hybrid supercomputing to financial services, energy exploration and medical imaging industries among others.

Applications for Cell-based hybrid supercomputing include: calculating cause and effect in capital markets in real-time, supercomputers in financial services can instantly predict the ripple effect of a stock market change throughout the markets. In medicine, complex 3-D renderings of tissues and bone structures will happen in real-time, as patients are being examined.

How fast is a petaflop?
Roadrunner operates at speeds exceeding one petaflop -- one thousand trillion calculations per second -- or one million billion calculations per second; or one quadrillion calculations per second.

* Lots of laptops. That's roughly equivalent to the combined computing power of 100,000 of today's fastest laptop computers. You would need a stack of laptops 1.5 miles high to equal Roadrunner's performance.

* It would take the entire population of the earth, -- about six billion - each of us working a handheld calculator at the rate of one second per calculation, more than 46 years to do what Roadrunner can do in one day.

* In the past 10 years, supercomputer power has increased about 1,000 times. Today, just three of Roadrunner's 3,456 Tri-blade units have the same power as the 1998 fastest computer. A complex physics calculation that will take Roadrunner one week to complete, would have taken the 1998 machine 20 years to finish - it would be half done today! If it were possible for cars to improve their gas mileage over the past decade at the same rate that supercomputers have improved their cost and efficiency, we'd be getting 200,000 miles to the gallon today.
