Argonne’s Superstar Supercomputer

Posted on by

Q. When do you expect Mira to be up and running?
A. Our hope is that we will receive the machine sometime in the third quarter of 2012 or early in 2013. Then it will take us three or four months to stand it up. It’s made up of 48 racks that weigh 2 tons each, so it takes a while to wheel it in, put it in place and wire it up.

Q. What are some cool projects being run on the supercomputer right now?
A. There is a current study on concrete that is pretty exciting. Concrete production is a $100 billion a year industry in the U.S. and generates a lot of carbon dioxide. A researcher from the National Institute of Standards and Technology is using the computer to figure out how to design better concrete that produces less out-gassing.

Phoenix NAP’s Response to Kasim Reed Shows Its Unreliability as a Data Center

Posted on by

Instead of blowing off the letter as patently contradicted by section 230, Phoenix NAP took the entire Lipstick Alley web site off line without any notice. In response to a strong protest, Phoenix NAP acknowledged that its failure to give notice was a mistake in process, but it had no sympathy for Lipstick Alley’s legal rights; PhoenixNAP told me that it takes claims of defamation seriously and, without regard to the merits of the dispute, its customers must “resolve the issue with the complaining party.”

EXT4 Data Corruption Bug Hits Stable Linux Kernels

Posted on by

As a warning for those who are normally quick to upgrade to the latest stable vanilla kernel releases, a serious EXT4 data corruption bug worked its way into the stable Linux 3.4, 3.5, and 3.6 kernel series.

via [Phoronix] EXT4 Data Corruption Bug Hits Stable Linux Kernels.

The reason why the problem happens rarely is that the effect of the buggy commit is that if the journal’s starting block is zero, we fail to truncate the journal when we unmount the file system. This can happen if we mount and then unmount the file system fairly quickly, before the log has a chance to wrap. After the first time this has happened, it’s not a disaster, since when we replay the journal, we’ll just replay some extra transactions. But if this happens twice, the oldest valid transaction will still not have gotten updated, but some of the newer transactions from the last mount session will have gotten written by the very latest transacitons, and when we then try to do the extra transaction replays, the metadata blocks can end up getting very scrambled indeed.

PlayStation 3: The Final Hack?

Posted on by

The release of the new custom firmware – and the LV0 decryption keys in particular – poses serious issues. While Sony will almost certainly change the PSN passphrase once again in the upcoming 4.30 update, the reveal of the LV0 key basically means that any system update released by Sony going forward can be decrypted with little or no effort whatsoever. Options Sony has in battling this leak are limited – every PS3 out there needs to be able to decrypt any firmware download package in order for the console to be updated (a 2006 launch PS3 can still update directly to the latest software). The release of the LV0 key allows for that to be achieved on PC, with the CoreOS and XMB files then re-encrypted using the existing 3.55 keys in order to be run on hacked consoles.

Wifi sniffing digital picture frame

After gutting the laptop and putting it in a custom picture frame, Driftnet, a program that listens network traffic and picks out images from TCP streams, was installed. [AUTUIN] tested his build with an open wireless connection in his building. The results provided a wonderful narrative that started with pictures from news sites than slowly devolved to pictures from a hot-or-not style website, an online dating site and finally pictures from the inevitable conclusion of that browsing session.

Wayland 1.0 Officially Released

Posted on by

In terms of actual Wayland adoption, Ubuntu developers may try again to have Wayland become the Ubuntu System Compositor for Ubuntu 13.04 in April, but I wouldn’t be surprised at all to see that delayed until Ubuntu 13.10 one year from now. Wayland is making nice progress and it’s becoming likely that it will succeed the X.Org Server on the modern Linux desktop, but there’s still much work ahead. Even the Wayland adoption within Fedora and the other more experimental / bleeding-edge Linux distributions has been slow.

Recycled photons set fresh quantum computing record

Laing’s team is also working towards that end. As part of the recycling technique, the researchers chained together two logic gates – a first for an optical quantum computer and an essential step in terms of hardware for building more complex devices. “To me, this achievement is more important than factoring 21, although to do so is an excellent demonstration of the technique’s power,” says Browne.

Moving from love-hate to hate-hate

Since the early 2000s, Samsung has been involved in designing of Apple’s A-range of chips as the main manufacturer. Samsung technologies contributed in the development of the A6 predecessors A5 and A5X, thanks to a broad agreement between the two companies. It now appears that the structure of the deal has been dramatically adjusted.

via Moving from love-hate to hate-hate.

As the patent war deepens, the two companies have seen a faster deterioration of their business partnership. Apple has already reduced its memory chip orders from Samsung for the iPhone 5 as it intends to widen its supply chain.

Unlike memory chips, which just read and write data, application processors control an entire computing system, therefore processor chips are more profitable.

Is Qualcomm the New AMD? Or the Next Intel?

Posted on by

With the news that Qualcomm will take over the CES keynote spot previously held by Microsoft, it really became clear what a dominant player the company has become. Quietly, while no one was paying attention, it’s become the second-most important semiconductor maker in the U.S.

via Is Qualcomm the New AMD? Or the Next Intel?.

Qualcomm started life in 1985 as a maker of cellular communications semiconductors, and it hasn’t strayed far from that formula. It’s pretty much the go-to company for CDMA chips and is now taking a lead in 4G LTE as well. So why would a company that’s so vertical become Intel’s biggest competitor? Because of where the two are headed.

Tier 1 Carriers Tackle Telco SDN

That approach tallies with the new network vision laid out by Michel’s colleague, Axel Clauberg, DT’s vice president of IP Architecture and Design, earlier this year. That vision sees SDN protocols being deployed in data centers and access networks but not in telecom operator core networks. (See DT Unveils New Network Vision.)
