    MojoKid writes “When AMD announced the high-end Radeon HD 7970, a lower cost Radeon HD 7950 based on the same GPU was planned to arrive a few weeks later. The GPU, which is based on AMD’s new architecture dubbed Graphics Core Next, is manufactured using TSMC’s 28nm process and features a whopping 4.31 billion transistors. In its full configuration, found on the Radeon HD 7970, the Tahiti GPU sports 2,048 stream processors with 128 texture (more…)



  • Installation of Blue Waters Petaflop Supercomputer Begins
    By on January 30, 2012 | Comments Off  Comments

    An anonymous reader writes “The National Center for Supercomputing Applications at the University of Illinois is finally getting the troubled Blue Waters supercomputer installed. After IBM walked away from the project after 3 years of planning, Cray stepped in to pick up the $188 million contract. Now, in around 9 months time, Blue Waters should be fully operational and achieve performance of 1 petaflop or more. As for the hardware… (more…)

  • Chromium-Based Spinoffs Worth Trying

    snydeq writes “InfoWorld’s Serdar Yegulalp takes an in-depth look at six Chromium-based spinoffs that bring privacy, security, social networking, and other interesting twists to Google’s Chrome browser. ‘When is it worth ditching Chrome for a Chromium-based remix? Some of the spinoffs are little better than novelties. Some have good ideas implemented in an iffy way. But a few point toward some genuinely new directions for both Chrome and (more…)

  • Book Review: OpenCL Programming Guide

    asgard4 writes “In recent years GPUs have become powerful computing devices whose power is not only used to generate pretty graphics on screen but also to perform heavy computation jobs that were exclusively reserved for high performance super computers in the past. Considering the vast diversity and rapid development cycle of GPUs from different vendors, it is not surprising that the ecosystem of programming environments has flourished (more…)

  • Scientists Create World’s Tiniest “Ear”
    By on January 16, 2012 | Comments Off  Comments

    sciencehabit writes “If you’ve ever wondered what a virus sounds like, or what noise a bacterium makes when it moves between hosts, you may soon get your chance to find out. Scientists have created the world’s tiniest ear. The ‘nano-ear,’ a microscopic particle of gold trapped by a laser beam, can detect sound a million times fainter than the threshold for human hearing. Researchers suggest the work could open up a whole new field of ‘acoustic (more…)

  • New CO2 Harvester Could Help Scrub the Air
    By on January 10, 2012 | Comments Off  Comments

    sciencehabit sends this excerpt from ScienceNOW: “Researchers in California have produced a cheap plastic capable of removing large amounts of carbon dioxide (CO2) from the air. Down the road, the new material could enable the development of large-scale batteries and even form the basis of ‘artificial trees’ that lower atmospheric concentrations of CO2 in an effort to stave off catastrophic climate change.”

  • Thick Dust Alters NASA Mars Rover Plans
    By on January 6, 2012 | Comments Off  Comments

    coondoggie writes “NASA’s long-running Mars rover Opportunity is getting ready for the harsh Martian winter, but this year for the first time in its nearly eight-year history it needs a sunnier location to continue its work. NASA said the rover, which depends on solar power for energy, is sitting just south of Mars’ equator and has worked through four Martian southern hemisphere winters. Being closer to the equator than its now defunct (more…)
