An anonymous reader writes "Last year tomography researchers of the ASTRA group at the University of Antwerp developed a desktop supercomputer with four NVIDIA GeForce 9800 GX2 graphics cards. The performance of the FASTRA GPGPU system was amazing; it was slightly faster than the university's 512-core supercomputer and cost less than 4000EUR. Today the researchers announce FASTRA II, a new 6000EUR GPGPU computing beast with six dual-GPU NVIDIA GeForce GTX 295 graphics cards and one GeForce GTX 275. The development of the new system was more complicated and there are still some stability issues, but tests reveal the 13 GPUs deliver 3.75x more performance than the old system. For the tomography reconstruction calculations these researchers need to do, the compact FASTRA II is four times faster than the university's supercomputer cluster, while being roughly 300 times more energy efficient."

An anonymous reader sends along this quote from New Scientist: "Google's web services may be considered cutting edge, but they run in warehouses filled with conventional computers. Now the search giant has revealed it is investigating the use of quantum computers to run its next generation of faster applications. Writing on Google's research blog this week, Hartmut Neven, head of its image recognition team, reveals that the Californian firm has for three years been quietly developing a quantum computer that can identify particular objects in a database of stills or video (PDF). Google has been doing this, Neven says, with D-Wave, a Canadian firm that has developed an on-chip array of quantum bits — or qubits — encoded in magnetically coupled superconducting loops."

1sockchuck writes "A supercomputing center in Quebec has transformed a huge concrete silo into the CLUMEQ Colossus, a data center filled with HPC clusters. The silo, which is 65 feet high with two-foot thick concrete walls, previously housed a Van de Graaf accelerator dating to the 1960s. It was redesigned to house three floors of server cabinets, arranged so cold air can flow from the outside of the facility through the racks and return via an interior 'hot core.' The construction and operation of the unique facility (PDF) are detailed in a presentation from CLUMEQ."

bleedingpegasus sends word that the US Air Force will be grabbing up 2,200 new PlayStation 3 consoles for research into supercomputing. They already have a cluster made from 336 of the old-style (non-Slim) consoles, which they've used for a variety of purposes, including "processing multiple radar images into higher resolution composite images (known as synthetic aperture radar image formation), high-def video processing, and 'neuromorphic computing.'" According to the Justification Review Document (DOC), "Once the hardware configuration is implemented, software code will be developed in-house for cluster implementation utilizing a Linux-based operating software."

kreyszig writes "The recent story of a cat brain simulation from IBM had me wondering if this was really possible as described. Now a senior researcher in the same field has publicly denounced IBM's claims." More optimisticaly, dontmakemethink points out an "astounding article about new 'Neurogrid' computer chips which offer brain-like computing with extremely low power consumption. In a simulation of 55 million neurons on a traditional supercomputer, 320,000 watts of power was required, while a 1-million neuron Neurogrid chip array is expected to consume less than one watt."

bennyboy64 contributes this excerpt from CRN Australia: "The CSIRO will this week launch a new supercomputer which uses a cluster of GPUs [pictures] to gain a processing capacity that competes with supercomputers over twice its size. The supercomputer is one of the world's first to combine traditional CPUs with the more powerful GPUs. It features 100 Intel Xeon CPU chips and 50 Tesla GPU chips, connected to an 80 Terabyte Hitachi Data Systems network attached storage unit. CSIRO science applications have already seen 10-100x speedups on NVIDIA GPUs."

judgecorp writes "UK company Iceotope has launched liquid-cooling technology which it says surpasses what can be done with water or air-cooling and can cut data centre cooling costs by up to 93 percent. Announced at Supercomputing 2009 in Portland, Oregon, the 'modular Liquid-Immersion Cooled Server' technology wraps each server in a cool-bag-like device, which cools components inside a server, rather than cooling the whole data centre, or even a traditional 'hot aisle.' Earlier this year, IBM predicted that in ten years all data centre servers might be water-cooled." Adds reader 1sockchuck, "The Hot Aisle has additional photos and diagrams of the new system."

CWmike writes "As amazing as today's supercomputing systems are, they remain primitive and current designs soak up too much power, space and money. And as big as they are today, supercomputers aren't big enough — a key topic for some of the estimated 11,000 people now gathering in Portland, Ore. for the 22nd annual supercomputing conference, SC09, will be the next performance goal: an exascale system. Today, supercomputers are well short of an exascale. The world's fastest system at Oak Ridge National Laboratory, according to the just released Top500 list, is a Cray XT5 system, which has 224,256 processing cores from six-core Opteron chips made by Advanced Micro Devices Inc. (AMD). The Jaguar is capable of a peak performance of 2.3 petaflops. But Jaguar's record is just a blip, a fleeting benchmark. The US Department of Energy has already begun holding workshops on building a system that's 1,000 times more powerful — an exascale system, said Buddy Bland, project director at the Oak Ridge Leadership Computing Facility that includes Jaguar. The exascale systems will be needed for high-resolution climate models, bio energy products and smart grid development as well as fusion energy design. The latter project is now under way in France: the International Thermonuclear Experimental Reactor, which the US is co-developing. They're expected to arrive in 2018 — in line with Moore's Law — which helps to explain the roughly 10-year development period. But the problems involved in reaching exaflop scale go well beyond Moore's Law."

jbrodkin writes "SiCortex had an idea that it thought would take the supercomputing world by storm — build the most energy-efficient HPC clusters on the planet. But the recession, and the difficulties of penetrating a market dominated by Intel-based machines, proved to be too much for the company to handle. SiCortex ended up folding earlier this year, and its story may be a cautionary tale for startups trying to bring innovation to the supercomputing industry."

angry tapir writes "Asustek has unveiled its first supercomputer, the desktop computer-sized ESC 1000, which uses Nvidia graphics processors to attain speeds up to 1.1 teraflops. Asus's ESC 1000 comes with a 3.33GHz Intel LGA1366 Xeon W3580 microprocessor designed for servers, along with 960 graphics processing cores from Nvidia inside three Tesla c1060 Computing Processors and one Quadro FX5800."

coondoggie writes "The US Department of Energy said today it will spend $32 million on a project that will deploy a large cloud computing test bed with thousands of Intel Nehalem CPU cores and explore commercial offerings from Amazon, Microsoft and Google. Ultimately, the project, known as Magellan, will look at cloud computing as a cost-effective and energy-efficient way for scientists to accelerate discoveries in a variety of disciplines, including analysis of scientific data sets in biology, climate change and physics, the DOE stated. Magellan will explore whether cloud computing can help meet the overwhelming demand for scientific computing. Although computation is an increasingly important tool for scientific discovery, and DOE operates some of the world's most powerful supercomputers, not all research applications require such massive computing power. The number of scientists who would benefit from mid-range computing far exceeds the amount of available resources, the DEO stated."

CWmike writes "They aren't selling personal supercomputers at Best Buy just yet. But that day probably isn't too far off, as the costs continue to fall and supercomputers become easier to use. Silicon Graphics International on Monday released its first so-called personal supercomputer. The new Octane III system is priced from $7,995 with one Xeon 5500 processor. The system can be expanded to an 80-core system with a capacity of up to 960GB of memory. This new supercomputer's peak performance of about 726 GFLOPS won't put it on the Top 500 supercomputer list, but that's not the point of the machine, SGI says. A key feature instead is the system's ease of use."

angry tapir writes "The San Diego Supercomputer Center has built a high-performance computer with solid-state drives, which the center says could help solve science problems faster than systems with traditional hard drives. The flash drives will provide faster data throughput, which should help the supercomputer analyze data an 'order of magnitude faster' than hard drive-based supercomputers, according to Allan Snavely, associate director at SDSC. SDSC intends to use the HPC system — called Dash — to develop new cures for diseases and to understand the development of Earth."

Joshua writes "Researchers from Japan have calculated Pi to over 2.5 trillion decimals using the T2K Open Supercomputer (which is currently ranked 47th in the world according to a June, 2009 report from Top500.org). This new number more than doubles the previous record of about 1.2 trillion decimals set in 2002 by another Japanese research team. Unfortunately, there still seems to be no pattern."

destinyland writes "Can we imprint the circuitry of the human brain onto a silicon chip? It requires a computational capacity of 36.8 petaflops — a thousand trillion floating point operations per second — but a team of European scientists has already simulated 200,000 neurons linked up by 50 million synaptic connections. And their brain-chip is scaleable, with plans to create a superchip mimicking 1 billion neurons and 10 trillion synapses. Unfortunately, the human brain has 22 billion neurons and 220 trillion synapses. Just remember Ray Kurzweil's argument: once a machine can achieve a human level of intelligence — it can also exceed it."

CWmike writes "Russia's launch of Sputnik in 1957 triggered a crisis of confidence in the US that helped drive the creation of a space program. Now, Russia is comparing the US's achievements in supercomputing with theirs, and they don't like what they see. In a speech on Tuesday, Russia's President, Dmitry Medvedev, criticized his country's IT industry almost to the point of sarcasm for failing to develop supercomputing technology, and urged a dramatic change in Russia's use of high-performance computing. Medvedev, at the opening address of a Security Council Meeting on Supercomputers in Moscow, told attendees that 476 out of the 500 supercomputers on the Top500 list were manufactured in the United States. 'Therefore, in general, our situation is very difficult,' he said."

Ponca City, We love you writes "The NY Times has the story of researchers at Sandia National Laboratories creating what is in effect a vast digital petri dish able to hold one million operating systems at once in an effort to study the behavior of botnets. Sandia scientist Ron Minnich, the inventor of LinuxBIOS, and his colleague Don Rudish have converted a Dell supercomputer to simulate a mini-Internet of one million computers. The researchers say they hope to be able to infect their digital petri dish with a botnet and then gather data on how the system behaves. 'When a forest is on fire you can fly over it, but with a cyber-attack you have no clear idea of what it looks like,' says Minnich. 'It's an extremely difficult task to get a global picture.' The Dell Thunderbird supercomputer, named MegaTux, has 4,480 Intel microprocessors running Linux virtual machines with Wine, making it possible to run 1 million copies of a Windows environment without paying licensing fees to Microsoft. MegaTux is an example of a new kind of computational science, in which computers are used to simulate scientific instruments that were once used in physical world laboratories. In the past, the researchers said, no one has tried to program a computer to simulate more than tens of thousands of operating systems."

BBCWatcher writes "In CPU news, IBM says that its POWER7 servers will start shipping in the first half of 2010, on schedule or perhaps even a few months early if you believe Wikipedia. Moreover, upgrades from a wide variety of POWER6 models will be mere CPU swaps, with the upgraded servers keeping their same serial numbers. (Bean counters like that.) POWER7 sports up to 8 cores per die, 4 threads per core, a clock speed a Hertz or two above 4 GHz, 45 nm process manufacturing, on-chip DDR3, and up to 1,000 micropartitions per machine. IBM claims that POWER7 will offer about 256 Gflops per die and two to three times the performance per watt as POWER6. IBM wants to keep taking orders now for its POWER6 gear (duh), so its sales reps are allegedly ready and eager to deal on 6-cum-7 packages. And it looks like that cunning plan could work rather well given Sun's Rock CPU cancellation and HP's delay of Tukwila Itanium to 2010. (Is anybody still in the server CPU race except IBM, Intel, and maybe AMD?) In 2006, POWER7 won the contest for a DARPA supercomputing R&D grant of $244 million, so you could say that each US citizen is in for about a dollar already."

An anonymous reader recommends an Ars Technica account of a breakthrough in efforts toward quantum computing. German scientists have managed to get cesium atoms in a state called a "quantum walk": basically a superposition of all the possible states of a particle. "Quantum walks were first proposed by physicist Richard Feynman and are, in terms of probability, the opposite of a random walk. A random walk might be modeled by a person flipping a coin, and for each flip he steps left for heads and right for tails. In this case, his most probable location is the center, with the probability distribution tapering off in either direction. A quantum walk involves the use of internal states and superpositions, and results in the hypothetical person 'exploring' every possible position simultaneously." In the abstract of the paper from Science (subscription needed for full-text access), the researchers say: "Our system allows the observation of the quantum-to-classical transition and paves the way for applications, such as quantum cellular automata."

Myrrh writes "Though an official announcement has not yet been made, it would appear that the BOINC project as a whole has exceeded two petaflop/s performance. The top page features this legend: '24-hour average: 2,793.53 TeraFLOPS.' According to last month's Top500 list of supercomputers, BOINC's performance is now beating that of the fastest supercomputer, RoadRunner, by more than a factor of two (with the caveat that BOINC has not been benchmarked on Linpack)."
