Supercomputer Built With 8 GPUs 232

FnH writes "Researchers at the University of Antwerp in Belgium have created a new supercomputer with standard gaming hardware. The system uses four NVIDIA GeForce 9800 GX2 graphics cards, costs less than €4,000 to build, and delivers roughly the same performance as a supercomputer cluster consisting of hundreds of PCs. This new system is used by the ASTRA research group, part of the Vision Lab of the University of Antwerp, to develop new computational methods for tomography. The guys explain the eight NVIDIA GPUs deliver the same performance for their work as more than 300 Intel Core 2 Duo 2.4GHz processors. On a normal desktop PC their tomography tasks would take several weeks but on this NVIDIA-based supercomputer it only takes a couple of hours. The NVIDIA graphics cards do the job very efficiently and consume a lot less power than a supercomputer cluster."

Modeling Supernovae With a Supercomputer 64

A team of scientists at the University of Chicago will be using 22 million processor-hours to simulate the physics of exploding stars. The team will make use of the Blue Gene/P supercomputer at Argonne National Laboratory to analyze four different scenarios for type Ia supernovae. Included in the link is a video simulation of a thermonuclear flame busting its way out of a white dwarf. The processing time was made possible by the Department of Energy's INCITE program. "Burning in a white dwarf can occur as a deflagration or as a detonation. 'Imagine a pool of gasoline and throw a match on it. That kind of burning across the pool of gasoline is a deflagration,' Jordan said. 'A detonation is simply if you were to light a stick of dynamite and allow it to explode.' In the Flash Center scenario, deflagration starts off-center of the star's core. The burning creates a hot bubble of less dense ash that pops out the side due to buoyancy, like a piece of Styrofoam submerged in water."

Purdue Plans a 1-Day Supercomputer "Barnraising" 97

An anonymous reader points out an article which says that "Purdue University says it will only need one day to install the largest supercomputer on a Big Ten campus. The so-called 'electronic barn-raising' will take place May 5 and involved more than 200 employees. The computer will be about the size of a semi trailer. Vice President for Information Technology at Purdue Gerry McCartney says it will be built in a single day to keep science and engineering researchers from facing a lengthy downtime." Another anonymous reader adds "To generate interest on campus, the organizers created a spoof movie trailer called 'Installation Day.'"

Cray, Intel To Partner On Hybrid Supercomputer 106

An anonymous reader writes "Intel convinced Cray to collaborate on what many believe will be the next generation of supercomputers — CPUs complemented by floating-point acceleration units. NVIDIA successfully placed its Tesla cards in an upcoming Bull supercomputer, and today we learn that Cray will be using Intel's x86 Larrabee accelerators in a supercomputer that is expected to be unveiled by 2011. It's a new chapter in the Intel-NVIDIA battle and a glimpse at the future of supercomputers operating in the petaflop range. The deal has also got to be a blow to AMD, which has been Cray's main chip supplier."

Matrix-Like VR Coming in the Near Future? 249

Anonymongoose writes "A researcher at Brookhaven National Lab reckons it could be just a few years before computers can pass through the uncanny valley. The article refers to this as a 'Graphics Turing Test': 'a computer can be considered intelligent if it can create an artificial world capable of fooling a person into believing it is the real thing.' Michael McGuigan has been performing some interesting experiments using Brookhaven's Blue Gene/L supercomputer and has shown that it can produce realistic lighting effects in real time. McGuigan's original research paper (pdf) is available online."

Building the World's 4th Fastest Supercomputer 75

ngkabra writes "In November 2007, a previously unheard of supercomputer called EKA, built by CRL, India came out of nowhere to become the 4th fastest supercomputer in the world. It is also the only supercomputer in the top 10 that hasn't taken any government funding — which means it has no strings attached against commercial exploitation. That is one of the reasons why Yahoo! chose EKA for the cloud computing research that they announced at the Hadoop Summit earlier this week. Yesterday, I attended a presentation by the team that built EKA, and they touched upon a lot of the technical details of EKA, and the challenges faced in designing and building it, which makes for interesting reading."

Sun Turns to Lasers to Speed Up Computer Chips 130

alphadogg writes to mention that Sun is attempting to move from the typical design of multiple small chips back to a unified single-wafer design. "The company is announcing today a $44 million contract from the Pentagon to explore replacing the wires between computer chips with laser beams. The technology, part of a field of computer science known as silicon photonics, would eradicate the most daunting bottleneck facing today's supercomputer designers: moving information rapidly to solve problems that require hundreds or thousands of processors."

A New Concept in Supercomputers 113

Steve Kerrison writes "With the power of CPUs ever-increasing and the number of cores in a system increasing too, having a supercomputer sit under your desk is no longer a pipe dream. But generally speaking, the extreme high end of modern computing consists of a big ugly box housing that generates a lot of noise. A UK system integrator has developed a concept PC that blows that all away. The eXtreme Concept PC (XCP) has quite a romantic design story, with inspiration coming from concept cars and the sarcophagus-like Cray T90. The end result is a system that resembles a Cylon — computing power never looked so ominous. Although just a concept, the company behind the design reckons there could be a (small) market for the systems, with varying levels of compute power accompanied by appropriate (say, LN2) cooling."

Debian Cluster Replaces Supercomputer For Weather Forecasting 160

wazza brings us a story about the Philippine government's weather service (PAGASA), which has recently used an eight-PC Debian cluster to replace an SGI supercomputer. The system processes data from local sources and the Global Telecommunication System, and it has reduced monthly operational costs by a factor of 20. Quoting: "'We tried several Linux flavours, including Red Hat, Mandrake, Fedora etc,' said Alan Pineda, head of ICT and flood forecasting at PAGASA. 'It doesn't make a dent in our budget; it's very negligible.' Pineda said PAGASA also wanted to implement a system which is very scalable. All of the equipment used for PICWIN's data gathering comes off-the-shelf, including laptops and mobile phones to transmit weather data such as temperature, humidity, rainfall, cloud formation and atmospheric pressure from field stations via SMS into PAGASA's central database."

Supercomputer Adds Credence to Standard Model 120

ScienceDaily is reporting that researchers at the University of Edinburgh and Southampton in cooperation with partners from Japan and the US have shed some light on the Standard Model of physics using a new computer model. "The project's enormously complex calculations relate to the behavior of tiny particles found in the nuclei of atoms, known as quarks. In order to carry out these calculations, the researchers first designed and built a supercomputer that was among the fastest in the world, capable of tens of trillions of calculations per second. The computations themselves have taken a further three years to complete. Their result shows that the Standard Model's claim to be the best theory invented holds firm. It raises the stakes for the riddle to be solved by experiments at the Large Hadron Collider at CERN, which will switch on later this year. Physicists' efforts to confront Standard Model predictions using the most powerful computers available with the most precise experiments offer no clues about what to expect."

Half-Petaflop Supercomputer Deployed In Austin 130

SethJohnson writes "Thanks to a $59 million National Science Foundation grant, there's likely to be a new king of the High Performance Computing Top 500 list. The contender is Ranger, a 15,744 Quad-Core AMD Opteron behemoth built by Sun and hosted at the University of Texas. Its peak processing power of 504 teraflops will be shared among over 500 researchers working across the even larger TeraGrid system. Although its expected lifespan is just four years, Ranger will provide 500 million processor hours to projects attempting to address societal grand challenges such as global climate change, water resource management, new energy sources, natural disasters, new materials and manufacturing processes, tissue and organ engineering, patient-specific medical therapies, and drug design."

Sandia Wants To Build Exaflop Computer 144

Dan100 brings us an announcement that Sandia and Oak Ridge National Laboratories are setting their sights on an exaflop supercomputer. Researchers from the two laboratories jointly launched the Institute for Advanced Architectures to facilitate development. One of the problems they hope to solve is how to provide each core of each processor with enough data so that cycles aren't going to waste. "The idea behind the institute — under consideration for a year and a half prior to its opening — is 'to close critical gaps between theoretical peak performance and actual performance on current supercomputers,' says Sandia project lead Sudip Dosanjh. 'We believe this can be done by developing novel and innovative computer architectures.' The institute is funded in FY08 by congressional mandate at $7.4 million."

Cellphone App Developed that Could Allow For 'Pocket Supercomputers' 73

Jack Spine writes "A robotics researcher at Accenture has given a demonstration of a 'Pocket Supercomputer' — a phone behaving like a thin client. It can be used to send images and video of objects in real time to a server where they can be identified and linked to relevant information, which can then be sent back to the user. 'The camera on the phone is used to take a video of an object — such as a book ... By offloading the processing from a mobile device onto a server, there are few limits on the size and processing power available to be used for the storage and search of images.' To pinpoint the features necessary to identify an object, the image is run through an algorithm called Scale-Invariant Feature Transform, or SIFT, a technology developed by academic David Lowe. The software extracts feature points from a jpeg and makes a match against images in the database. If a match exists then the software on the server retrieves information and sends it back to the user's phone. A 'three-dimensional' image of an object can also be uploaded onto the phone, to look at the virtual object from different angles. The motion-tracking technology Accenture uses for this is a free library of algorithms called Open Computer Vision."

Researchers Simulate Building Block of Rat's Brain 224

slick_shoes passes on an article in the Guardian about the Blue Brain project in Switzerland that has developed a computer simulation of the neocortical column — the basic building block of the neocortex, the higher functioning part of our brains — of a two-week-old rat. (Here is the project site.) The model, running on an IBM Blue Gene/L supercomputer, simulates 10,000 neurons and all their interconnections. It behaves exactly like its biological counterpart. Thousands of such NCCs make up a rat's neocortex, and millions a human's. "Project director Henry Markram believes that with the state of technology today, it is possible to build an entire rat's neocortex. From there, it's cats, then monkeys and finally, a human brain."

Computer Model Points To the Missing Matter 97

eldavojohn writes "There exists a little-known problem of missing regular matter that has perhaps been overshadowed by the mysteries of dark matter and dark energy. Computer models show that there should be about 40% more regular matter than we see... so where is it? From the article: 'The study indicated a significant portion of the gas is in the filaments — which connect galaxy clusters — hidden from direct observation in enormous gas clouds in intergalactic space known as the Warm-Hot Intergalactic Medium, or WHIM, said CU-Boulder Professor Jack Burns... The team performed one of the largest cosmological supercomputer simulations ever, cramming 2.5 percent of the visible universe inside a computer to model a region more than 1.5 billion light-years across.' This hypothesis will be investigated and hopefully proved/disproved when telescopes are completed in Chile and the Antarctic. The paper will be up for review in this week's edition of the the Astrophysical Journal."
