Google and NASA Snap Up D-Wave Quantum Computer 108

Posted by Unknown Lamer
from the at-least-we-think-they-did dept.
ananyo writes "D-Wave, the small company that sells the world's only commercial quantum computer, has just bagged an impressive new customer: a collaboration between Google, NASA and the non-profit Universities Space Research Association. The three organizations have joined forces to install a D-Wave Two, the computer company's latest model, in a facility launched by the collaboration — the Quantum Artificial Intelligence Lab at NASA's Ames Research Center. The lab will explore areas such as machine learning — useful for functions such as language translation, image searches and voice-command recognition. The Google-led collaboration is only the second customer to buy computer from D-Wave — Lockheed Martin was the first."

Why We Should Build a Supercomputer Replica of the Human Brain 389

Posted by Soulskill
from the brain-and-brain-what-is-brain dept.
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."

from the complicating-factors dept.
anzha writes "Horst Simon, Deputy Director of Lawrence Berkeley National Laboratory, has stood up at conferences of late and said the unthinkable: supercomputing is hitting a wall and will not build an exaFLOPS HPC system by 2020. This is defined as one that passes linpack with a performance of one exaFLOPS sustained or better. He's even placed money on it. You can read the original presentation here."

Japan Planning Exascale Computer For 2020 38

Posted by Soulskill
from the go-big-or-go-home dept.
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

Posted by Soulskill
from the let's-do-the-timewarp-again dept.
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."

Indiana University Dedicates Biggest College-Owned Supercomputer 83

Posted by samzenpus
from the getting-an-upgrade dept.
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."

Harvard Grid Computing Project Discovers 20k Organic Photovoltaic Molecules 125

Posted by Unknown Lamer
from the by-your-powers-combined dept.
Lucas123 writes "In June, Harvard's Clean Energy Project plans to release to solar power developers a list of the top 20,000 organic compounds, any one of which could be used to make cheap, printable photovoltaic cells (PVCs). The CEP uses the computing resources of IBM's World Community Grid for the computational chemistry to find the best molecules for organic photovoltaics culled the list from about 7 million. About 6,000 computers are part of the project at any one time. If successful, the crowdsourcing-style project, which has been crunching data for the past two-plus years, could lead to PVCs that cost about as much as paint to cover a one-meter square wall." The big thing here is that they've discovered a lot of organic molecules that have the potential for 10% or better conversion; roughly equivalent to the current best PV material, and twice as efficient as other available organic PV materials.

US Gov't Blocks Sales To Russian Supercomputer Maker 116

Posted by timothy
from the all-knowing-state dept.
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."

'Blue Waters' Supercomputer Lucky To Exist 39

Posted by Soulskill
from the your-new-parents-love-you-very-much dept.
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."

Too Much Gold Delays World's Fastest Supercomputer 111

Posted by timothy
from the other-people's-problems dept.
Nerval's Lobster writes "The fastest supercomputer in the world, Oak Ridge National Laboratory's 'Titan,' has been delayed because an excess of gold on its motherboard connectors has prevented it from working properly. Titan was originally turned on last October and climbed to the top of the Top500 list of the fastest supercomputers shortly thereafter. Problems with Titan were first discovered in February, when the supercomputer just missed its stability requirement. At that time, the problems with the connectors were isolated as the culprit, and ORNL decided to take some of Titan's 200 cabinets offline and ship their motherboards back to the manufacturer, Cray, for repairs. The connectors affected the ability of the GPUs in the system to talk to the main processors. Oak Ridge Today's John Huotari noted the problem was due to too much gold mixed in with the solder."

from the one-transistor-earthling-please dept.
Vigile writes "NVIDIA's new GeForce GTX TITAN graphics card is being announced today and is utilizing the GK110 GPU first announced in May of 2012 for HPC and supercomputing markets. The GPU touts computing horsepower at 4.5 TFLOPS provided by the 2,688 single precision cores, 896 double precision cores, a 384-bit memory bus and 6GB of on-board memory doubling the included frame buffer that AMD's Radeon HD 7970 uses. With a make up of 7.1 billion transistors and a 551 mm^2 die size, GK110 is very close to the reticle limit for current lithography technology! The GTX TITAN introduces a new GPU Boost revision based on real-time temperature monitoring and support for monitor refresh rate overclocking that will entice gamers and with a $999 price tag, the card could be one of the best GPGPU options on the market." HotHardware says the card "will easily be the most powerful single-GPU powered graphics card available when it ships, with relatively quiet operation and lower power consumption than the previous generation GeForce GTX 690 dual-GPU card."

Stanford Uses Million-Core Supercomputer To Model Supersonic Jet Noise 66

Posted by Soulskill

coondoggie writes "Stanford researchers said this week they had used a supercomputer with 1,572,864 compute cores to predict the noise generated by a supersonic jet engine. 'Computational fluid dynamics simulations test all aspects of a supercomputer. The waves propagating throughout the simulation require a carefully orchestrated balance between computation, memory and communication. Supercomputers like Sequoia divvy up the complex math into smaller parts so they can be computed simultaneously. The more cores you have, the faster and more complex the calculations can be. And yet, despite the additional computing horsepower, the difficulty of the calculations only becomes more challenging with more cores. At the one-million-core level, previously innocuous parts of the computer code can suddenly become bottlenecks.'"

from the go-big-or-go-home dept.
Nerval's Lobster writes "The U.S. Department of Science has presented a difficult challenge to vendors: deliver a supercomputer with roughly 10 to 30 petaflops of performance, yet filled with energy-efficient multi-core architecture. The draft copy (.DOC) of the DOE's requirements provide for two systems: 'Trinity,' which will offer computing resources to the Los Alamos National Laboratory (LANL), Sandia National Laboratories (SNL), and Lawrence Livermore National Laboratory (LLNL), during the 2016-2020 timeframe; and NERSC-8, the replacement for the current NERSC-6 'Hopper' supercomputer first deployed in 2010 for the DOE facilities. Hopper debuted at number five in the list of Top500 supercomputers, and can crunch numbers at the petaflop level. The DOE wants a machine with performance at between 10 to 30 times Hopper's capabilities, with the ability to support one compute job that could take up over half of the available compute resources at any one time."

Three-Mile-High Supercomputer Poses Unique Challenges 80

from the hamsters-have-trouble-at-that-altitude dept.
Nerval's Lobster writes "Building and operating a supercomputer at more than three miles above sea level poses some unique problems, the designers of the recently installed Atacama Large Millimeter/submillimeter Array (ALMA) Correlator discovered. The ALMA computer serves as the brains behind the ALMA astronomical telescope, a partnership between Europe, North American, and South American agencies. It's the largest such project in existence. Based high in the Andes mountains in northern Chile, the telescope includes an array of 66 dish-shaped antennas in two groups. The telescope correlator's 134 million processors continually combine and compare faint celestial signals received by the antennas in the ALMA array, which are separated by up to 16 kilometers, enabling the antennas to work together as a single, enormous telescope, according to Space Daily. The extreme high altitude makes it nearly impossible to maintain on-site support staff for significant lengths of time, with ALMA reporting that human intervention will be kept to an absolute minimum. Data acquired via the array is archived at a lower-altitude support site. The altitude also limited the construction crew's ability to actually build the thing, requiring 20 weeks of human effort just to unpack and install it."

Einstein@Home Set To Break Petaflops Barrier 96

Posted by Unknown Lamer
from the onward-upward dept.
hazeii writes "Einstein@home, the distributed computing project searching for the gravitational waves predicted to exist by Albert Einstein, looks set to breach the 1 Petaflops barrier around midnight UTC tonight. Put into context, if it was in the Top500 Supercomputers list, it would be in at number 24. I'm sure there are plenty of Slashdot readers who can contribute enough CPU and GPU cycles to push them well over 1,000 teraflops — and maybe even discover a pulsar in the process." From their forums: "At 14:45 we had 989.2 TFLOPS with an increase of 1.3 TFLOPS/h. In principle that's enough to reach 1001.1 TFLOPS at midnight (UTC) but very often, like yesterday, between 22:45 and 22:50 there occurs a drop of about 5 TFLOPS. So we will have very likely hit 1 PFLOPS in the early morning tomorrow. "
