IBM turbo charges world's fastest supercomputer

Blue Gene has long division licked. Next: killer sudoku


IBM has unleashed a new iteration of its chess-playing powerhouse Blue Gene, which it also reckons is useful in academic and commercial fields like drug discovery and mineral exploration.

The Blue Gene/P supercedes the Blue Gene/L with faster Power PC cores, more memory and a symmetric multiprocessing (SMP) mode to support multi-threaded apps, as IBM scrambles to keep supercomputing in line with the coding vogue in cluster systems.

IBM says Blue Gene/P is three times more powerful than its predecessor, and seven times more energy efficient than its supercomputing bretheren. The firm has visions of flogging systems to financial institutions. Dave Turek, VP of deep computing said: "This is on course with an adoption cycle - from government labs to leading enterprises – that we’ve seen before in the high-performance computing market."

To that end, the software environment has been tweaked to provide better app support and system management. Blue Gene systems run a version of Linux.

Back on the silicon side of things, each two foot by two foot board in a Blue Gene/P setup comprises 32 chips, which each contain four Power PC 450s clocking 850MHz. The boards are stacked 32-high to build racks which will churn 13.9 teraflops. The petaflop configuration calls on 72 of these racks; a total of 294,912 processing cores. The modular system tops out at a 216-rack cluster delivering three petaflops.

According to IBM, for a pile of laptops to run at the same speed, it would have to be a mile and a half high [please address all pedantry to IBM, Computer Road, Big Corporation City, NY 10101, USA].

The US Department of Energy will be first to wrangle the beast, when Argonne National Laboratory lets it loose later this year. In the UK, the Science and Technology Facilities Council's Daresbury Laboratory in Cheshire is planning a deployment.®

  • DigitalOcean tries to take sting out of price hike with $4 VM
    Cloud biz says it is reacting to customer mix largely shifting from lone devs to SMBs

    DigitalOcean attempted to lessen the sting of higher prices this week by announcing a cut-rate instance aimed at developers and hobbyists.

    The $4-a-month droplet — what the infrastructure-as-a-service outfit calls its virtual machines — pairs a single virtual CPU with 512 MB of memory, 10 GB of SSD storage, and 500 GB a month in network bandwidth.

    The launch comes as DigitalOcean plans a sweeping price hike across much of its product portfolio, effective July 1. On the low-end, most instances will see pricing increase between $1 and $16 a month, but on the high-end, some products will see increases of as much as $120 in the case of DigitalOceans’ top-tier storage-optimized virtual machines.

  • GPL legal battle: Vizio told by judge it will have to answer breach-of-contract claims
    Fine-print crucially deemed contractual agreement as well as copyright license in smartTV source-code case

    The Software Freedom Conservancy (SFC) has won a significant legal victory in its ongoing effort to force Vizio to publish the source code of its SmartCast TV software, which is said to contain GPLv2 and LGPLv2.1 copyleft-licensed components.

    SFC sued Vizio, claiming it was in breach of contract by failing to obey the terms of the GPLv2 and LGPLv2.1 licenses that require source code to be made public when certain conditions are met, and sought declaratory relief on behalf of Vizio TV owners. SFC wanted its breach-of-contract arguments to be heard by the Orange County Superior Court in California, though Vizio kicked the matter up to the district court level in central California where it hoped to avoid the contract issue and defend its corner using just federal copyright law.

    On Friday, Federal District Judge Josephine Staton sided with SFC and granted its motion to send its lawsuit back to superior court. To do so, Judge Staton had to decide whether or not the federal Copyright Act preempted the SFC's breach-of-contract allegations; in the end, she decided it didn't.

  • US brings first-of-its-kind criminal charges of Bitcoin-based sanctions-busting
    Citizen allegedly moved $10m-plus in BTC into banned nation

    US prosecutors have accused an American citizen of illegally funneling more than $10 million in Bitcoin into an economically sanctioned country.

    It's said the resulting criminal charges of sanctions busting through the use of cryptocurrency are the first of their kind to be brought in the US.

    Under the United States' International Emergency Economic Powers Act (IEEA), it is illegal for a citizen or institution within the US to transfer funds, directly or indirectly, to a sanctioned country, such as Iran, Cuba, North Korea, or Russia. If there is evidence the IEEA was willfully violated, a criminal case should follow. If an individual or financial exchange was unwittingly involved in evading sanctions, they may be subject to civil action.

  • Meta hires network chip guru from Intel: What does this mean for future silicon?
    Why be a customer when you can develop your own custom semiconductors

    Analysis Here's something that should raise eyebrows in the datacenter world: Facebook parent company Meta has hired a veteran networking chip engineer from Intel to lead silicon design efforts in the internet giant's infrastructure hardware engineering group.

    Jon Dama started as director of silicon in May for Meta's infrastructure hardware group, a role that has him "responsible for several design teams innovating the datacenter for scale," according to his LinkedIn profile. In a blurb, Dama indicated that a team is already in place at Meta, and he hopes to "scale the next several doublings of data processing" with them.

    Though we couldn't confirm it, we think it's likely that Dama is reporting to Alexis Bjorlin, Meta's vice president of infrastructure hardware who previously worked with Dama when she was general manager of Intel's Connectivity group before serving a two-year stint at Broadcom.

  • Lithium production needs investment to keep pace with battery demand
    Report says $42b will need to be poured into industry over next decade

    Growing demand for lithium for batteries means the sector will need $42 billion of investment to meet the anticipated level of orders by the end of the decade, according to a report.

    Lithium is used in batteries that power smartphones and laptops, but there is also rising use in electric vehicles which is putting additional pressure on supplies.

    The report, Benchmark Mineral Intelligence, predicts that demand will reach 2.4 million tons of lithium carbonate equivalent by 2030, roughly four times the 600,000 tons of lithium forecast to be produced this year.
