Using Kexec Allows Starting Linux In PlayStation 4 70

jones_supa writes: Team fail0verflow, the hacker group who made Sony PlayStation 4, has introduced another method to start Linux in the game console. Instead of the previous exploit which was based on a security hole in an old PS4 firmware version, the new trick allows a kexec call to start Linux through Orbis OS (the FreeBSD-based system software of PS4). The code can be found in GitHub. Maybe this will lead to more and better PlayStation clusters.

Biological Supercomputers Powered By ATP Could Be A Reality Some Day (dispatchtribunal.com) 66

hypnosec writes: Our cells are powered by Adenosine triphosphate (ATP) and according to a new study, they could be a power source for the next generation of biological supercomputers capable of processing information very quickly and accurately using parallel networks in the same way that massive electronic super computers do. Published in the Proceedings of the National Academy of Sciences (PNAS), the paper describes a model of biological computer that is effectively a very complex network in a very small area, and is based on a combination of geometrical modeling and engineering know-how (on the nano scale). Researchers involved with the study claim that it is the first step in showing that this kind of biological supercomputer can actually work.

Marvin Minsky, Pioneer In Artificial Intelligence, Dies at 88 (nytimes.com) 76

An anonymous reader sends word that Marvin Lee Minsky, co-founder of the Massachusetts Institute of Technology's AI laboratory, has died. The Times reports: "Marvin Minsky, who combined a scientist’s thirst for knowledge with a philosopher’s quest for truth as a pioneering explorer of artificial intelligence, work that helped inspire the creation of the personal computer and the Internet, died on Sunday night in Boston. He was 88. Well before the advent of the microprocessor and the supercomputer, Professor Minsky, a revered computer science educator at M.I.T., laid the foundation for the field of artificial intelligence by demonstrating the possibilities of imparting common-sense reasoning to computers."

Seymour Cray and the Development of Supercomputers (linuxvoice.com) 54

An anonymous reader writes: Linux Voice has a nice retrospective on the development of the Cray supercomputer. Quoting: "Firstly, within the CPU, there were multiple functional units (execution units forming discrete parts of the CPU) which could operate in parallel; so it could begin the next instruction while still computing the current one, as long as the current one wasn't required by the next. It also had an instruction cache of sorts to reduce the time the CPU spent waiting for the next instruction fetch result. Secondly, the CPU itself contained 10 parallel functional units (parallel processors, or PPs), so it could operate on ten different instructions simultaneously. This was unique for the time." They also discuss modern efforts to emulate the old Crays: "...what Chris wanted was real Cray-1 software: specifically, COS. Turns out, no one has it. He managed to track down a couple of disk packs (vast 10lb ones), but then had to get something to read them in the end he used an impressive home-brew robot solution to map the information, but that still left deciphering it. A Norwegian coder, Yngve Ådlandsvik, managed to play with the data set enough to figure out the data format and other bits and pieces, and wrote a data recovery script."

Quantum Computer Security? NASA Doesn't Want To Talk About It (csoonline.com) 86

itwbennett writes: At a press event at NASA's Advanced Supercomputer Facility in Silicon Valley on Tuesday, the agency was keen to talk about the capabilities of its D-Wave 2X quantum computer. 'Engineers from NASA and Google are using it to research a whole new area of computing — one that's years from commercialization but could revolutionize the way computers solve complex problems,' writes Martyn Williams. But when questions turned to the system's security, a NASA moderator quickly shut things down [VIDEO], saying the topic was 'for later discussion at another time.'

Intel Launches 72-Core Knight's Landing Xeon Phi Supercomputer Chip (hothardware.com) 179

MojoKid writes: Intel announced a new version of their Xeon Phi line-up today, otherwise known as Knight's Landing. Whatever you want to call it, the pre-production chip is a 72-core coprocessor solution manufactured on a 14nm process with 3D Tri-Gate transistors. The family of coprocessors is built around Intel's MIC (Many Integrated Core) architecture which itself is part of a larger PCI-E add-in card solution for supercomputing applications. Knight's Landing succeeds the current version of Xeon Phi, codenamed Knight's Corner, which has up to 61 cores. The new Knight's Landing chip ups the ante with double-precision performance exceeding 3 teraflops and over 8 teraflops of single-precision performance. It also has 16GB of on-package MCDRAM memory, which Intel says is five times more power efficient as GDDR5 and three times as dense.

Immersion Cooling Drives Server Power Densities To Insane New Heights (datacenterfrontier.com) 80

1sockchuck writes: By immersing IT equipment in liquid coolant, a new data center is reaching extreme power densities of 250 kW per enclosure. At 40 megawatts, the data center is also taking immersion cooling to an entirely new scale, building on a much smaller proof-of-concept from a Hong Kong skyscraper. The facility is being built by Bitcoin specialist BitFury and reflects how the harsh economics of industrial mining have prompted cryptocurrency firms to focus on data center design to cut costs and boost power. But this type of radical energy efficiency may soon be key to America's effort to build an exascale computer and the increasingly extreme data-crunching requirements for cloud and analytics.

IBM's Watson Is Now Analyzing Your Vacation Photos 117

jfruh writes: IBM's Jeopardy-winning supercomputer Watson is now suite of cloud-based services that developers can use to add cognitive capabilities to applications, and one of its powers is visual analysis. Visual Insights analyzes images and videos posted to services like Twitter, Facebook and Instagram, then looks for patterns and trends in what people have been posting. Watson turns what it gleans into structured data, making it easier to load into a database and act upon — which is clearly appealing to marketers and just as clearly carries disturbing privacy implications.

NASA's Hurricane Model Resolution Increases Nearly 10-Fold Since Katrina 89

zdburke writes: Thanks to improvements in satellites and on-the-ground computing power, NASA's ability to model hurricane data has come a long way in the ten years since Katrina devastated New Orleans. Their blog notes, "Today's models have up to ten times the resolution than those during Hurricane Katrina and allow for a more accurate look inside the hurricane. Imagine going from video game figures made of large chunky blocks to detailed human characters that visibly show beads of sweat on their forehead." Gizmodo covered the post too and added some technical details, noting that, "the supercomputer has more than 45,000 processor cores and runs at 1.995 petfalops."

China To Impose Export Control On High Tech Drones and Supercomputers 67

hackingbear writes: Following similar hi-tech export restriction policies in the U.S. (or perhaps in response to the U.S. ban on China,) China will impose export control on some drones and high performance computers starting on August 15th, according to an announcement published on Friday by China's Ministry of Commerce and the General Administration of Customs. The ban includes (official documents in Chinese) drone that can take off in wind speed exceeding 46.4km/hour or can continuously fly for over 1 hour as well as electronic components specifically designed or modified for supercomputers with speed over 8 petaflops. Companies must acquire specific permits before exporting such items. Drones and supercomputers are the two areas where China is the leader or among the top players. China is using its rapidly expanding defense budget to make impressive advances in (military) drone technology, prompting some to worry that the United States' global dominance in the market could soon be challenged. The tightening of regulations comes two weeks after an incident in disputed Kashmir in which the Pakistani army claimed to have shot down an Indian "spy drone", reportedly Chinese-made. China's 33-petaflops Tianhe-2, currently the fastest supercomputer in the world, while still using Intel Xeon processors, makes use of the home-grown interconnect, arguably the most important component of modern supercomputers.

19-Year-Old's Supercomputer Chip Startup Gets DARPA Contract, Funding 150

An anonymous reader writes: 19-year-old Thomas Sohmers, who launched his own supercomputer chip startup back in March, has won a DARPA contract and funding for his company. Rex Computing, is currently finishing up the architecture of its final verified RTL, which is expected to be completed by the end of the year. The new Neo chips will be sampled next year, before moving into full production in mid-2017.The Platform reports: "In addition to the young company’s first round of financing, Rex Computing has also secured close to $100,000 in DARPA funds. The full description can be found midway down this DARPA document under 'Programming New Computers,' and has, according to Sohmers, been instrumental as they start down the verification and early tape out process for the Neo chips. The funding is designed to target the automatic scratch pad memory tools, which, according to Sohmers is the 'difficult part and where this approach might succeed where others have failed is the static compilation analysis technology at runtime.'"

Cray To Build Australia's Fastest Supercomputer 54

Bismillah writes: US supercomputer vendor Cray has scored the contract to build the Australian Bureau of Meteorology's new system, said to be capable of 1.6 petaFLOPS and with an upgrade option in three years' time to hit 5 petaFLOPS. From the iTnews story: "The increase in capacity will allow the BoM to deal with growth in the 1TB of data it collects every day, which it expects to increase by 30 percent every 18 months to two years. It will also allow the agency to collect new areas of information it previously lacked the capacity for. 'The new observation platforms that are coming online are bringing quite a lot more data,' supercomputer program director Tim Pugh told iTnews.

Preserving Radio Silence At the Square Kilometer Array 27

johnslater writes: The Guardian has a story on the radio silence requirements at the Square Kilometer Array in Australia. The RF requirements for the SKA are far more stringent than at the US National Radio Quiet Zone at Greenbank, to such an extent that the specialized supercomputers to control the array have specially shielded data centers, and the as-yet-unbuilt supercomputer to process the data will be located hundreds of miles away in Perth. To quote Dr John Morgan in the article: "You can guarantee that the thing that SKA will be remembered for ... is going to be the thing you have not thought of. It's the unknown unknown."

Supercomputing Cluster Immersed In Oil Yields Extreme Efficiency 67

1sockchuck writes: A new supercomputing cluster immersed in tanks of dielectric fluid has posted extreme efficiency ratings. The Vienna Scientific Cluster 3 combines several efficiency techniques to create a system that is stingy in its use of power, cooling and water. VSC3 recorded a PUE (Power Usage Efficiency) of 1.02, putting it in the realm of data centers run by Google and Facebook. The system avoids the use of chillers and air handlers, and doesn't require any water to cool the fluid in the cooling tanks. Limiting use of water is a growing priority for data center operators, as cooling towers can use large volumes of water resources. The VSC3 system packs 600 teraflops of computing power into 1,000 square feet of floor space.

Baidu Forced To Withdraw Last Month's ImageNet Test Results 94

elwinc writes: Back in mid-May, Baidu, a computer research and services organization in Mainland China, announced impressive results on the ImageNet "Large Scale Visual Recognition Challenge," besting results posted by Google and Microsoft. Turns out, Baidu gamed the system, creating 30 accounts and running far more than the 2 tests per week allowed in the contest. Having been caught cheating, Baidu has been banned for a year from the challenge. I believe all competitors are using variations on the convolutional neural network, AKA deep network. Running the test dozens of times per week might allow a competitor to pre-tune parameters for the particular problem, thus producing results that might not generalize to other problems. All of which makes it quite ironic that a Baidu scientist crowed "Our company is now leading the race in computer intelligence!"

US Blocks Intel From Selling Xeon Chips To Chinese Supercomputer Projects 229

itwbennett writes: U.S. government agencies have stopped Intel from selling microprocessors for China's supercomputers, apparently reflecting concern about their use in nuclear tests. In February, four supercomputing institutions in China were placed on a U.S. government list that effectively bans them from receiving certain U.S. exports. The institutions were involved in building Tianhe-2 and Tianhe-1A, both of which have allegedly been used for 'nuclear explosive activities,' according to a notice (PDF) posted by the U.S. Department of Commerce. Intel has been selling its Xeon chips to Chinese supercomputers for years, so the ban represents a blow to its business.
