A Database of Brains 25

aarondubrow writes "Researchers recently created OpenfMRI, a web-based, supercomputer-powered tool that makes it easier for researchers to process, share, compare and rapidly analyze fMRI brain scans from many different studies. Applying supercomputing to the fMRI analysis allows researchers to conduct larger studies, test more hypotheses, and accommodate the growing spatial and time resolution of brain scans. The ultimate goal is to collect enough brain data to develop a bottom-up understanding of brain function."

Hackers Spawn Web Supercomputer On Way To Chess World Record 130

New submitter DeathGrippe sends in an article from Wired about a new take on distributed computing efforts like SETI@Home. From Wired: "By inserting a bit of JavaScript into a webpage, Pethiyagoda says, a site owner could distribute a problem amongst all the site's visitors. Visitors' computers or phones would be running calculations in the background while they read a page. With enough visitors, he says, a site could farm out enough small calculations to solve some difficult problems. ... With this year's run on the value of Bitcoins — the popular digital currency — security expert Mikko Hyppönen thinks that criminals might soon start experimenting with this type of distributed computing too. He believes that crooks could infect websites with JavaScript code that would turn visitors into unsuspecting Bitcoin miners. As long as you're visiting the website, you're mining coins for someone else."

Full Details Uncovered on Chinese Tianhe-2 Supercomputer 56

An anonymous reader writes "With help from a draft report (PDF) from Oak Ridge National Laboratory's Jack Dongarra, who also spearheads the process of verifying the top of the pack supercomputer, we get a detailed look at China's Tianhe-2 system. As noted previously, the system will be housed at the National Supercomputer Center in Guangzhou and has been aimed at providing an open platform for research and education and to provide a high performance computing service for southern China. From Jack's details: '... was sent results showing a run of HPL benchmark using 14,336 nodes, that run was made using 50 GB of the memory of each node and achieved 30.65 petaflops out of a theoretical peak of 49.19 petaflops, or an efficiency of 62.3% of theoretical peak performance taking a little over 5 hours to complete.The fastest result shown was using 90% of the machine. They are expecting to make improvements and increase the number of nodes used in the test.'"

Researchers Determine Chemical Structure of HIV Capsid 90

adeelarshad82 writes "Researchers at the University of Illinois at Urbana-Champaign (UIUC) have determined the precise chemical structure of the HIV 'capsid,' a protein shell that protects the virus's genetic material and is a key to its virulence. The experiment involved mapping an incredible 64 million atoms to simulate the HIV capsid, pictured here. Interestingly no current HIV drugs target the HIV capsid and researchers believe that understanding the structure of the HIV capsid may hold the key to the development of new and more effective antiretroviral drugs. What makes this whole experiment even more fascinating is the use of Blue Waters, a Cray XK7 supercomputer with 3,000 Nvidia Tesla K20X GPU accelerators."

Motorola Building "Self-Aware" Smartphone 117

Nerval's Lobster writes "Back in the ancient days of 2009, Motorola Mobility earned considerable buzz with its Droid smartphone. Marketed as an iPhone alternative, the device featured a sliding QWERTY keyboard and a chunky black body that seemed positively Schwarzenegger-esque in comparison to its svelte Apple rival. But Motorola failed to translate that buzz into sustained momentum in the smartphone space. Instead, Samsung became the dominant Android smartphone manufacturer, battling toe-to-toe with Apple for market-share and profits. Even Google acquiring Motorola for the princely sum of $12.1 billion didn't really seem to alter the equation very much. Motorola CEO Dennis Woodside wants to change all that. In a May 29 talk at AllThingsD's D11 conference, he told the audience that Motorola has a 'hero phone' in the works, dubbed the Moto X—and that it's self-aware. 'It anticipates my needs,' he said, according to AllThingD's live blog of the event. But what does that actually mean? Thanks to embedded sensors, the phone knows when the user removes it from his or her pocket; in theory, that capability could serve broader applications, such as the phone recognizing where the user is located within a city and serving up content and applications accordingly. In fact, it sounds a bit like Google Now on steroids—or like the smartphone precursor to SkyNet, the supercomputer from the Terminator movies that's so intelligent, it decides that the world would be better off if it ruled over humanity."

Supercomputers At TACC Getting a Speed Boost 14

Nerval's Lobster writes "The Texas Advanced Computing Center (TACC) at The University of Texas at Austin is going to get a major speed boost this summer, and it won't come from new CPUs. Internet2, the research project that acts as a test bed for new Internet technologies, will take TACC's massive computing system from 10GB to 100GB of Ethernet throughput. TACC supercomputers are regularly found near the top of the Top 500 supercomputer list, which ranks the world's fastest supercomputers. But while the supercomputers were fast, the connectivity wasn't quite up to snuff. So TACC began the emigration to the Internet2 network. TACC is a key partner in the UT Research Cyberinfrastructure, which provides a combination of advanced computing, high-bandwidth network connectivity, and large data storage to all 15 of the UT system schools. So not only is TACC upgraded to Internet2s 100GB and 8.8 terabit-per-second optical network, platform, services and technologies, so is the entire UT system. 'This Internet2 bandwidth upgrade will enable researchers to achieve a tenfold increase in moving data to/from TACC's supercomputing, visualization and data storage systems, greatly increasing their productivity and their ability to make new discoveries,' TACC director Jay Boisseau wrote in a statement."

Computer Network Piecing Together a Jigsaw of Ancient Jewish Lore 127

First time accepted submitter aravenwood writes "The New York Times and the Times of Israel report today that artificial intelligence and a network of 100 computers in a basement in Tel Aviv University are being used to match 320,000 fragments of documents dating as far back as the 9th century in an attempt to reassemble the original documents. Since the trove of documents from the Jewish community of Cairo was discovered in 1896 only about 4000 of them have been pieced together, and the hope is that the new technique, which involves taking photographs of the fragments and using image recognition and other algorithms to match the language, spacing, and handwriting style of the text along with the shape of the fragment to other fragments could revolutionize not only the study of this trove documents, which has been split up into 67 different collections around the world since its discovery, but also how humanities disciplines study documents like these. They expect to make 12 billion comparisons of different fragments before the project is completed — they have already performed 2.8 billion. Among the documents, some dating from 950, was the discovery of letters by Moses Maimonides and that Cairene Jews were involved in the import of flax, linen, and sheep cheese from Sicily."

Some Scientists Question Whether Quantum Computer Really Is Quantum 170

gbrumfiel writes "Last week, Google and NASA announced a partnership to buy a new quantum computer from Canadian firm D-Wave Systems. But NPR news reports that many scientists are still questioning whether new machine really is quantum. Long-time critic and computer scientist Scott Aaronson has a long post detailing the current state of affairs. At issue is whether the 512 quantum bits at the processor's core are 'entangled' together. Measuring that entanglement directly destroys it, so D-Wave has had a hard time convincing skeptics. As with all things quantum mechanical, the devil is in the details. Still it may not matter: D-Wave's machine appears to be far faster at solving certain kinds of problems (PDF), regardless of how it works."

NWS Announces Big Computer Upgrade 161

riverat1 writes "After being embarrassed when the Europeans did a better job forecasting Sandy than the National Weather Service Congress allocated $25 million ($23.7 after sequestration) in the Sandy relief bill for upgrades to forecasting and supercomputer resources. The NWS announced that their main forecasting computer will be upgraded from the current 213 TeraFlops to 2,600 TFlops by fiscal year 2015, over a twelve-fold increase. The upgrade is expected to increase the horizontal grid scale by a factor of 3 allowing more precise forecasting of local features of weather. The some of the allocated funds will also be used to hire some contract scientists to improve the forecast model physics and enhance the collection and assimilation of data."

Why We Should Build a Supercomputer Replica of the Human Brain 393

An anonymous reader sends this excerpt from Wired: "[Henry] Markram was proposing a project that has bedeviled AI researchers for decades, that most had presumed was impossible. He wanted to build a working mind from the ground up. ... The self-assured scientist claims that the only thing preventing scientists from understanding the human brain in its entirety — from the molecular level all the way to the mystery of consciousness — is a lack of ambition. If only neuroscience would follow his lead, he insists, his Human Brain Project could simulate the functions of all 86 billion neurons in the human brain, and the 100 trillion connections that link them. And once that's done, once you've built a plug-and-play brain, anything is possible. You could take it apart to figure out the causes of brain diseases. You could rig it to robotics and develop a whole new range of intelligent technologies. You could strap on a pair of virtual reality glasses and experience a brain other than your own."

Japan Planning Exascale Computer For 2020 38

Nerval's Lobster writes "Japan has thrown its hat into the ring for exascale computing, reported the country's newspapers. The goal: achieve one exaFLOPS of performance by 2020. Japan's finance ministry has agreed to begin work next fiscal year on a supercomputer with a performance capability 100 times that of the K computer, a 10-petaFLOPS computer that debuted as the most powerful supercomputer in the world in 2011. The midterm report for the new supercomputer was concluded Thursday, the Asahi Shimbun business daily reported. The Japan Times was slightly more conservative, reporting that the Education, Culture, Sports, Science and Technology Ministry will seek funding to design the new machine in its fiscal 2014 budget request — implying that the project has not necessarily been approved. The science ministry is hoping to keep the cost of the new supercomputer below the ¥110 billion mark ($1.08 billion) that was required to develop the K computer, the paper reported. (Slashdot couldn't find any evidence that the project had been approved on the ministry Webpage, although the K computer was mentioned several times in a discussion of public-private partnerships.)"

Sequoia Supercomputer Sets Record With 'Time Warp' 39

Nerval's Lobster writes "The 'Sequoia' Blue Gene/Q supercomputer at the Lawrence Livermore National Laboratory (LLNL) has topped a new HPC record, helped along by a new 'Time Warp' protocol and benchmark that detects parallelism and automatically improves performance as the system scales out to more cores. Scientists at the Rensselaer Polytechnic Institute and LLNL said Sequoia topped 504 billion events per second, breaking the previous record of 12.2 billion events per second set in 2009. The scientists believe that such performance enables them to reach so-called "planetary"-scale calculations, enough to factor in all 7 billion people in the world, or the billions of hosts found on the Internet. 'We are reaching an interesting transition point where our simulation capability is limited more by our ability to develop, maintain, and validate models of complex systems than by our ability to execute them in a timely manner,' Chris Carothers, director of the Computational Center for Nanotechnology Innovations at RPI, wrote in a statement."

Putin Reportedly Comments On T-Platform Supercomputer Flap 49

Nerval's Lobster writes "In March, the U.S. Department of Commerce's Bureau of Industry and Security added T-Platforms' businesses in Germany, Russia and Taiwan to the 'Entity List,' which includes those believed to be acting contrary to the national security or foreign policy interests of the United States. Commerce felt, according to the notice, that T-Platforms may be illegally assisting the Russian military and/or its nuclear program. In the meantime, Russian president Vladimir Putin has reportedly weighed in on the T-Platforms question. 'That's right. The use of political levers for unfair competition,' Putin said, according to RBTH.ru. 'Our European colleagues are independent people and they claim they want to work with us in certain spheres, yet they act as though they are absolutely dependent and unable to make their own decision. Is that so?' It's odd that Putin was quoted talking about 'European colleagues' when the Americans were responsible for cutting T-Platforms off."

Indiana University Dedicates Biggest College-Owned Supercomputer 83

Indiana University has replaced their supercomputer, Big Red, with a new system predictably named Big Red II. At the dedication HPC scientist Paul Messina said: "It's important that this is a university-owned resource. ... Here you have the opportunity to have your own faculty, staff and students get access with very little difficulty to this wonderful resource." From the article: "Big Red II is a Cray-built machine, which uses both GPU-enabled and standard CPU compute nodes to deliver a petaflop -- or 1 quadrillion floating-point operations per second -- of max performance. Each of the 344 CPU nodes uses two 16-core AMD Abu Dhabi processors, while the 676 GPU nodes use one 16-core AMD Interlagos and one NVIDIA Kepler K20."

US Gov't Blocks Sales To Russian Supercomputer Maker 116

Nerval's Lobster writes "T-Platforms, which manufactured the fastest supercomputer in Russia (and twenty-sixth fastest in the world), has been placed on the IT equivalent of the no-fly list. In March, the U.S. Department of Commerce's Bureau of Industry and Security added T-Platforms' businesses in Germany, Russia and Taiwan to the 'Entity List,' which includes those believed to be acting contrary to the national security or foreign policy interests of the United States. U.S. IT companies are essentially banned from doing business with T-Platforms, especially with regards to HPC hardware such as microprocessors, which could be used for what the government views as illegal purposes. The rule, discovered by HPCWire, was published in March. According to the rule, Commerce's End-User Review Committee (ERC) believes that T-Platforms may be assisting the Russian government and military conduct nuclear research — which, given historical tensions between the two countries, apparently falls outside the bounds of permitted use. An email address that T-Platforms listed for its German office bounced, and Slashdot was unable to reach executives at its Russian headquarters for comment."

Dell, Raymond Unveil 'One Smartwatch Per Child'; Icahn Erupts 34

An anonymous reader writes "As Dell's (DELL:NASDAQ GS) board reviews three competing proposals for taking the company private, including a $24.4 billion deal led by founder and CEO Michael Dell and Silver Lake Partners, the company has announced it is entering the suddenly crowded smartwatch sweepstakes along with Apple, Google, and Samsung. The twist is that Dell's product will target the low end of the market — the extreme low end, in the words of CEO Dell, because 'that's where most of the world's customers are'. Dell's smartwatch, projected to cost just 19.99 USD ($319.99 before Dell's mail-in rebate) will allow children in developing countries to communicate via voice and text, collaborate on school activities, and perform native-to-English voice and text translations with the help of Dell's new ARM supercomputer. Dell says premium models will also perform translations in the reverse direction, i.e. English-to-native. Open Source advocate Eric S. Raymond, who joined Dell for the conference call, stated 'this is the beginning of what I call the Bazaar Wrist model of the mobile Internet. It'll be a battle of ideas against what I call the Office Tower Wrist model that Apple and Google will be selling.' Billionaire investor Carl Icahn, who recently launched a rival bid for Dell, labeled the product an 'a pig in the poke' as well as a 'distraction and extreme waste of shareholder value', adding that his $7.44 Wal-Mart watch 'works just great for me and probably anyone else'."

'Blue Waters' Supercomputer Lucky To Exist 39

Nerval's Lobster writes "One could argue that the University of Illinois' "Blue Waters" supercomputer, scheduled to officially open for business March 28, is lucky to be alive. The 11.6 petaflop supercomputer, commissioned by the University and the National Science Foundation (NSF), will rank in the upper echelon of the world's fastest machines—its compute power would place it third on the current list, just above Japan's K Computer. However, the system will not be submitted to the TOP500 list because of concerns with the way the list is calculated, officials said. University officials and the NSF are lucky to have a machine at all. That's due in part to IBM, which reportedly backed out of the contract when the company determined that it couldn't make a profit. The university then turned to Cray, which would have had to replace what was presumably a POWER or Xeon installation with the current mix of AMD CPUs and Nvidia GPU coprocessors. Allen Blatecky, director of NSF's Division of Advanced Cyberinfrastructure, told Fox that pulling the plug was a 'real possibility.' And Cray itself had to work to find the parts necessary for the supercomputer to begin at least trial operations in the fall of 2012."

World's Most Powerful Private Supercomputer Will Hunt Oil and Gas 135

Nerval's Lobster writes "French oil conglomerate Total has inaugurated the world's ninth-most-powerful supercomputer, Panega. Its purpose: seek out new reservoirs of oil and gas. The supercomputer's total output is 2.3 petaflops, which should place it about ninth on today's TOP500 list, last updated in November. The announcement came as Dell and others prepare to inaugurate a new supercomputer, Stampede, in Texas on March 27. What's noteworthy about Pangea, however, is that it will be the most powerful supercomputer owned and used by private industry; the vast majority of such systems are in use by government agencies and academic institutions. Right now, the most powerful private supercomputer for commercial use is the Hermit supercomputer in Stuttgart; ranked 27th in the world, the 831.4 Tflop machine is a public-private partnership between the University of Stuttgart and hww GmbH. Panega, which will cost 60 million Euro ($77.8 million) over four years, will assist decision-making in the exploration of complex geological areas and to increase the efficiency of hydrocarbon production in compliance with the safety standards and with respect for the environment, Total said. Pangea will be will be stored at Total's research center in the southwestern French city of Pau."
