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."

An anonymous reader writes "Passing the Turing test is the holy grail of artificial intelligence (AI) and now researchers claim it may be possible using the world's fastest supercomputer (IBM's Blue Gene). This version of the Turing test pits a human conversing with a synthetic character powered by Rascals software crafted at Rensselaer Polytechnic Institute. RPI is aiming to pass AI's final exam this fall, by pairing the most powerful university-based supercomputing system in the world with its new multimedia group which is designing a holodeck, a la Star Trek."

hasu notes that scientists at the National Institute for Materials Science at Tsukuba in Japan have created a device, consisting of 17 duroquinone molecules on a gold surface, that can in theory encode 4.3 billion outcomes. The "device" does not constitute a practical computer, since it requires both a scanning tunneling microscope and operation near absolute zero. A single duroquinone is surrounded by sixteen others, and weak chemical bonds allow a pulse to the central molecule to shift all seventeen molecules in a variety of ways. Each duroquinone has four different "settings," so a single pulse can have 4^16 possible outcomes. As a demonstration the researchers docked 8 other nano-devices to their 17-molecule computer. It is unclear how well they have characterized the inputs that result in 4.3 billion different outputs. They are working on a 3D design that would have 1,024 duroquinone molecules surrounding a central one.

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."

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."

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."

The Narrative Fallacy writes "Scott Aaronson has posted a draft of his article from this month's Scientific American on the limitations of quantum computers (PDF) discussing the question: Will quantum computers let us transcend the human condition and become as powerful as gods, or are they a physical absurdity destined to be exposed as the twenty-first century's perpetual-motion machine? Aaronson says that while a quantum computer could quickly factor large numbers, and thereby break most of the cryptographic codes used on the Internet today, there's reason to think that not even a quantum computer could solve the crucial class of NP-complete problems efficiently. Aaronson contends that any method for solving NP-complete problems in polynomial time may violate the laws of physics and that this may be a fundamental limitation on technology no different than the second law of thermodynamics or the impossibility of faster-than-light communication."

anzha writes "It seems that that Linux Networx, the pioneering Linux supercomputing company, has gone belly up. SGI announced that it has bought the core assets of LNXI. Furthermore, the rumors are that the doors were locked and employees were just given their paychecks. This analysis, on the other hand, claims that SGI has 'made employment offers to many LNXI engineers.' It's unclear what kind of support will be extended to customers of LNXI's Clusterworx Advanced products. What does this mean for the future of Linux supercomputing?"

An anonymous reader writes "IBM has published a research paper describing an initiative called Project Kittyhawk, aimed at building "a global-scale shared computer capable of hosting the entire Internet as an application." Nicholas Carr describes the paper with the words "Forget Thomas Watson's apocryphal remark that the world may need only five computers. Maybe it needs just one." Here is the original paper."

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."

Weather Storm writes "DOE's Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program supports computationally intensive, large-scale research projects at a governmental level. They recently awarded 265 million processor-hours to 55 scientific projects, the largest amount of supercomputing resource awards donated in the DOE's history and three times that of last year's award. The winners were chosen based on their potential breakthroughs in the areas of science and engineering research, and the suitability of the project for using supercomputers. This year's INCITE applications ranged from developing nanomaterials to advancing the nation's basic understanding of physics and chemistry, and from designing quieter cars to improving commercial aircraft design. The next round of the INCITE competition will be announced this summer. Expansion of the DOE Office of Science's computational capabilities should approximately quadruple the 2009 INCITE award allocations to close to a billion processor hours."

bmsleight writes "The Guardian has a story on the HECToR, The largest supercomputer in the UK — around five times more powerful than its predecessor, HPCx, which is also at the University of Edinburgh. It measures up well internationally, sitting at 17 in the top500.org list of the most powerful computers in the world."

inkslinger77 writes "A team of ten MIT students powered a supercomputer for twenty minutes by pedaling bicycles. They duly claimed the world record for human-powered computing (HPC). They powered a SiCortex SC648 supercomputer with a Linux cluster of 648 CPUs and almost 1TB of main memory in a single cabinet. The system is low-powered and draws 1,200 watts without needing special power supplies or cooling..."

malachiorion writes "The Tunguska event, an explosion on June 30, 1908, cleared an 800-sq.-mi. swath of Siberian forest. Was it a UFO crash? An alien weapons test? Now, Sandia National Laboratories has released its own explanation for the Tunguska event. Using supercomputers to create a 3D simulation of the explosion, the Department of Energy-funded nuke lab has determined that Tunguska was, indeed, the explosion of a relatively small asteroid. The simulation videos are well worth checking out — they show a fireball slamming into the earth from the asteroid's air burst. The researchers caution that we should be keeping watch for many more small, potentially earth-impacting asteroids than we are currently tracking."

Stochastism writes "In yet another small step toward realistic quantum computing Australian researchers have developed a light based 4-qubit quantum computer. It has already calculated the prime roots of fifteen, three and five. 'The quantum circuit pioneered by the Queensland researchers involves using a laser to send "entangled" photons through a linear optical circuit ... The Queensland research group acknowledged that the theorised code cracking ability of quantum computers may be why Australian quantum computer research is in part funded by a US government defence intelligence agency, the Defense Advanced Research Projects Agency (DARPA).'"

Stony Stevenson writes with the news that, despite a ban on US PC hardware, Iranian techs have built an enormously powerful supercomputer from 216 AMD processors. The Linux-cluster machine has a 'theoretical peak performance of 860 gig-flops'. "The disclosure, made in an undated posting on [the University of] Amirkabir's Web site, brought an immediate response Monday from AMD, which said it has never authorized shipments of products either directly or indirectly to Iran or any other embargoed country."

Via Game|Life, a story on The Age site suggests that password crackers are really enjoying their PlayStation 3s ... and not because Ratchet is a great game. An NZ-based security researcher stated at a local security conference that the supercomputing power of the PS3 is being put to more nefarious uses than Folding@home. "Speed is important to "brute force" password cracking, which relies on guessing all possible combinations of the characters that make up the password. The accelerated technique means passwords protecting Office, PDF, ZIP and Lotus Notes ID files can be cracked with breathtaking speed. However, many other password types are handled more securely in software and remain unaffected by Breese's claimed speed increase." Sony does have some good news this week, though. Either the holiday season or a price drop here in the states has led to a massive sales increase.

An anonymous reader writes "Russian police seized Garry Kasparov, the Russian chess champion, for staging a political rally against Vladimir Putin. IBM's Deep Blue computer was the first to beat a world champion when it defeated Kasparov, who is one of the strongest players in history." He's also been a giant critic of the Russian administration which is increasingly restricting free speech.

An anonymous reader writes to tell us that Physicists from both the University of Surrey and Salford University have devised a method to trap a multi-colored rainbow of light inside a prism. "Previous attempts to slow and capture light have involved extremely low or cryogenic temperatures, have been extremely costly, and have only worked with one specific frequency of light at a time. The technique proposed by Professor Hess and Mr Kosmas Tsakmakidis involves the use of negative refractive index metamaterials along with the exploitation of the Goos Hänchen effect, which shows that when light hits an object or an interface between two media it does not immediately bounce back but seems to travel very slightly along that object, or in the case of metamaterials, travels very slightly backwards along the object."

Stony Stevenson writes "Canadian researchers have promised to squeeze "decades" of cancer research into just two years by harnessing the power of a global PC grid. The scientists are the first from Canada to use IBM's World Community Grid network of PCs and laptops with the power equivalent to one of the globe's top five fastest supercomputers. The team will use the grid to analyze the results of experiments on proteins using data collected by scientists at the Hauptman-Woodward Medical Research Institute in Buffalo, New York. The researchers estimate that this analysis would take conventional computer systems 162 years to complete."
