IBM and NVIDIA give US supercomputers a brain boost

US supercomputers are having to grow up, with a wider set of tasks the machines at Lawrence Livermore and Oak Ridge National Laboratories are being asked to do by the researchers, national security teams, and others given access to them demanding a change in architecture in order to keep them flexible. IBM and NVIDIA are upgrading two supercomputers - Sierra at Lawrence Livermore, and Summit at Oak Ridge - using IBM's support for the open-source OpenPOWER standard, increasing the interconnect speed of the CPU and GPU processors responsible for doing all the heavy-duty crunching. In fact, so the companies claim, there'll be as much as a tenfold cut in processing time for real-world applications.

NVIDIA talks smarter supercomputers for better AI

NVIDIA talks smarter supercomputers for better AI

NVIDIA has discussed its plans to push supercomputer technology and enable much more intelligent artificial intelligence (AI), demonstrating its CUDA for Machine Leaning system. Discussing image detection, gesture and speech recognition, recommendation engines, and more, NVIDIA set out its stall for why its GPUs are the natural platform for AI.

Google gives an update on D-Wave 2 quantum computer benchmark status

Google gives an update on D-Wave 2 quantum computer benchmark status

As a tech company, Google has been known to branch out into different areas of interests, from self-driving cars to smart wearable technology and, more recently, to robotics. One thing it has dipped its toe in also quite recently is the field of quantum computing, having jointly purchased a fancy D-Wave 2 supercomputer. Now its A.I. Lab Team is trying to give an update on just how much that $10 million expenditure is worth.

Scientists trace superconductivity anomalies to a single point

Scientists trace superconductivity anomalies to a single point

Superconducting materials that function at room temperature make electrons behave unpredictably. The electrons sometimes arrange themselves in lines or around atoms in an asymmetrical arrangement. This is one reason superconductors have not proliferated into everyday use -- an advance that would render everything from power lines to personal computers far, far more efficient. But two scientists now say they have discovered the cause of those anomalies in zero-resistance systems and are now working on a practical way to get rid of them.

NVIDIA Tesla K40 accelerator is world’s fastest for supercomputers

NVIDIA Tesla K40 accelerator is world’s fastest for supercomputers

NVIDIA has outed its most powerful GPU-based processing accelerator to-date, the Tesla K40, and it's headed to supercomputers in 2014. Mustering up to 40x the performance of the last-gen K20X, the K40 delivers 1.43 teraflops of processing power from its 2,880 CUDA cores and 12GB of GDDR5 memory. There'll be plenty of opportunity for it to show what it can do, too; NVIDIA has inked a collaboration with IBM that will see the two company's silicon sharing supercomputer space from next year.

Tianhe-2 Chinese supercomputer snatches No.1 place from USA

Tianhe-2 Chinese supercomputer snatches No.1 place from USA

China's Tianhe-2 supercomputer has reclaimed the top spot for speed, almost twice as fast as the previous reigning champion, the US's Titan. Tianhe-2, unsurprisingly the follow-up to the Tianhe-1A which grabbed pole position back in 2010, is capable of 33.86 petaflops per second of processing, ranking organization TOP500 confirms, far ahead of the 17.59 petaflops per second Titan is capable of.

Bitcoin mining operation tops world’s fastest supercomputers

Bitcoin mining operation tops world’s fastest supercomputers

Bitcoin, the online currency that looks to revolutionize how we look at money in an online environment, is rising in popularity. However, in order to create Bitcoins, you have to mine them first, meaning that you give up a certain amount of computational power in order to process the creation of Bitcoins (similar to Folding@Home). In fact, Bitcoin mining is such a huge thing right now, that the entire mining network is faster than most of the world's fastest supercomputers combined.

Indiana University’s petaflop supercomputer bucks public trend

Indiana University’s petaflop supercomputer bucks public trend

Indiana University's new petaflop supercomputer is the first supercomputer to be a "dedicated university resource." It has been named Big Red II, and is a big replacement to IU's previous supercomputer, Big Red, which reached speed of 28 teraflops, drastically slower than Big Red II's one petaflop speeds. Big Red II will be used to help students and staff members with their research on various subjects.
