Today on In Case You Missed It: Virginia Tech researchers found they can better clean fruits and vegetables with electrified water bubbles. Japanese scientists are also harnessing the power of electricity, but this time putting it into a fork to sub...

University of Illinois’ Blue Waters supercomputer now running around the clock

University of Illinois' Blue Waters supercomputer now running around the clock

Things got a tad hairy for the University of Illinois at Urbana-Champaign's Blue Waters supercomputer when IBM halted work on it in 2011, but with funding from the National Science Foundation, the one-petaflop system is now crunching numbers 24/7. The behemoth resides within the National Center for Supercomputing Applications (NCSA) and is composed of 237 Cray XE6 cabinets and 32 of the XK7 variety. NVIDIA GK110 Kepler GPU accelerators line the inside of the machine and are flanked by 22,640 compute nodes, which each pack two AMD 6276 Interlagos processors clocked at 2.3 GHz or higher. At its peak performance, the rig can churn out 11.61 quadrillion calculations per second. According to the NCSA, all that horsepower earns Blue Waters the title of the most powerful supercomputer on a university campus. Now that it's cranking away around-the-clock, it'll be used in projects investigating everything from how viruses infect cells to weather predictions.

Alt-week 9.15.12: The ultimate wind machine, Egyptian Lego and the office of our dreams

Posted on by

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days.

Alt-week 9.15.12: The ultimate wind machine, Egyptian Lego and the office of our dreams

Sometimes we wonder, what would we have ended up doing if we didn't spend our time trawling the web for the week's best alternative tech stories? We could have been paleontologists, novelists, engineers, or if we were really lucky, worked for Google. Instead, here we are bringing you some of the more colorful tech-tales from the last seven days, which we're really not complaining about. That said though, at least on this occasion, we got to taste a bit of all the above. This is alt-week.

Researchers propose à la carte internet services, overhaul for web infrastructure

Researchers propose à la carte internet services, overhaul for web infrastructure

A quintet of researchers funded by the National Science Foundation have envisioned a new internet architecture, one where features could be purchased à la carte. The proposed framework would allow users to fine tune their experience by choosing from a variety of connection services. Let's say, for example, that a customer's connection is fine for browsing the web, but it doesn't pass muster for streaming content -- a service dedicated to video delivery could be added to close the gap. "Ultimately, this should make the internet more flexible and efficient, and will drive innovation among service providers to cater to user needs," report co-author Rudra Dutta told The Abstract. A piecemeal next-gen web is no easy feat, however, as it would require revamping the web's infrastructure with new protocols for choosing particular features, completing payments and monitoring network performance. The group's rough blueprint will be presented at a conference next week, but you can thumb through their short paper at the source.

10 Gigabit per-second connection between US and China demoed

Posted on by

Internet2You, sir or ma'am, should probably not get too excited. Chances are, this trans-Pacific 10 Gigabit link won't do you any good, personally. On the other hand, researchers working together across the oceanic divide have tons to cheer about. The China Education and Research Network, the National Science Foundation and Indiana University worked together with BGI, one of the largest genomics organizations in the world, to christen the connection by transferring 24 Gigabytes of genomic data from Beijing to UC Davis in under 30 seconds. As a benchmark, the same file was sent between the same locations over the regular ol' Internet and it took over 26 hours. The high-speed link should prove to be a major boon for genetic research and DNA sequencing.

White House aims to make internet ’90 percent cheaper’ to build, teams up with Mozilla for $500k competition

White House wants to make the internet '90 percent cheaper' to build, teams up with Mozilla for $500,000 competition

The government's US Ignite partnership aims to push the growth of next-generation broadband networks, teaming up with over 100 start-ups, universities and existing tech companies like HP, Comcast and Verizon for the project. The President is set to sign an executive order today that aims to cut the cost of broadband construction across federal roadways and properties by up to 90 percent. The White House is also is looking to improve "next-generation applications and (the) digital experience," running on networks that are a heady 100 times faster than what's in use today. The National Science Foundation has thrown in $250 million to assist the partnership's creation of a national 1-gigabit network that would connect together academic and developer hubs. Mozilla has decided to team up with the foundation to offer up a $500,000 prize pot for developers looking to help create the "internet of the future". The challenge aims on education, healthcare, public safety and other (admittedly broad) topics, with the top ideas capable of grabbing $15,000 from the prize fund. And if Google reckons gigabit networks are the way to go, who's the White House to argue?

Supercomputer gets a memory boost with 380 petabytes of magnetic tape

Supercomputer gets a memory boost with 380 petabytes of magnetic tape

Remember the Cray XK6 at the University of Illinois that drives the National Science Foundation's Blue Waters project? Well, it looks like it's getting a little memory upgrade, sorta. We're not talking a slick new SSD here, or even a sweet NAS, all that computational power requires nothing less than... tape. Okay, so it's actually a full storage infrastructure, and some of it -- 25 petabytes no less -- will be disk-based. The rest -- a not insignificant 380 petabytes -- will be the good old magnetic stuff. The idea is that the disk part will be used for instant access, with the tape section serving as "nearline" storage -- something between an archive and online solution. Spectra Logic is providing the tape, and says it'll take a couple of years to implement the whole lot. Once complete, the system will support the supercomputer's lofty tasks, such as understanding how the cosmos evolved after the Big Bang and, y'know designing new materials at the atomic level. And we thought we were excited about out next desktop.
