AMD and Cray are building the 'world's most powerful supercomputer'
The US may be set to hang onto the crown of having the world's most powerful supercomputer for some time. Cray Computing and AMD are building an exascale machine with the Oak Ridge National Laboratory. The system is set to debut in 2021, the same year Cray and Intel are scheduled to deliver the Aurora exascale supercomputer to the Argonne National Laboratory.
Tiny light-up barcodes help researchers identify DNA molecules
How do you identify one molecule among tens of thousands? Traditionally, scientists dye molecules in various colors. But what if each individual molecule had its own unique identifier? Researchers at Duke University are trying to make that a reality by labeling molecules with short strands of light-up DNA. The team discussed their invention, which they deem "temporal barcodes", in a paper published this month in the journal ACS Synthetic Biology.
Researchers accidentally turn carbon dioxide into ethanol
Science has a long and storied history of looking for one thing but finding something better instead. Penicillin, radioactivity, science boxes...I mean microwave ovens -- all of these discoveries came in the the search for something else. On Monday, researchers at the Oak Ridge National Laboratory in Tennessee announced that they too had unintentionally discovered something incredible: a means of transforming carbon dioxide directly into ethanol using a single catalyst.
IBM's new computers may change how we process big data
IBM HQ. INT. DAY. An oppressive curtain of rain beats down against the window of this small meeting room in IBM's New York HQ. Two IBM scientists are engaging in excited conversation with a representative from the DEPARTMENT OF ENERGY while a third IBM employee sits at one end, removed from the action, chewing their pen and staring out of the window. DOE REPRESENTATIVE: What do you mean $300 million won't get me the two supercomputers I need? SCIENTIST #1: You're generating too much data. There isn't enough bandwidth for it all to go through. DOE REPRESENTATIVE: I don't understand. You're the supercomputer company, make it happen!
Cray's Jaguar supercomputer upgraded with NVIDIA Tesla GPUs, renamed Titan
Cray's Jaguar (or XK7) supercomputer at Oak Ridge National Laboratory has been loaded up with the first shipping NVIDIA Tesla K20 GPUs and renamed Titan. Loaded with 18,688 of the Kepler-based K20s, Titan's peak performance is more than 20 petaflops. Sure, the machine has an equal number of 16-core AMD Opteron 6274 processors as it does GPUs, but the Tesla hardware packs 90 percent of the entire processing punch. Titan is roughly ten times faster and five times more energy efficient than it was before the name change, yet it fits into the same 200 cabinets as its predecessor. Now that it's complete, the rig will analyze data and create simulations for scientific projects ranging from topics including climate change to nuclear energy. The hardware behind Titan isn't meant to power your gaming sessions, but the NVIDIA says lessons learned from supercomputer GPU development trickle back down to consumer-grade cards. For the full lowdown on the beefed-up supercomputer, hit the jump for a pair of press releases.
Nanocones make solar cells more efficient, sinister looking
Going green is de rigeur, so the sun is becoming a much-preferred source of power. However, solar cells' inefficient harvesting of heliacal energies is a major reason they haven't usurped the power of petroleum. Good thing the big brains at Oak Ridge National Laboratory are looking to change that with nanocone-based solar technology. The teeny-tiny cones are made of zinc oxide and create "an intrinsic electric field distribution" to improve electrical charge transport within solar cells. We aren't sure what that means, but we do know the prickly-looking design provides a 3.2 percent light-to-power conversion efficiency that's a substantial improvement over the meager 1.8 percent offered by today's flat photovoltaics made of similar materials. That's 80 percent more efficient, and 100 percent more awesome.
Cray Jaguar leaps past IBM Roadrunner as world's fastest supercomputer and pun generator (video)
Cray has finally clawed IBM back from the lead position on the Top500 Supercomputer chip-measuring contest. After just missing out on the title to IBM's Roadrunner last year, Cray's XT5 supercomputer (aka, Jaguar) at Oak Ridge National Lab in Tennessee received an update from quad- to six-core Opteron processors to boast a 2.3 petaflop per second performance peak (theoretical) and 1.75 petaflops as measured by the Linpack benchmark; a feat requiring almost a quarter million AMD cores. IBM's Roadrunner, the very first supercomputer to race past the petaflop per second threshold, managed just 1.042 petaflops by comparison. Remember, one petaflop per second is equivalent to one quadrillion calculations per second. Of course, chip makers put their own spins on the list by noting that 4 of the top 5 systems depend on AMD for performance while Intel can be found powering 402 of the Top500. Video of the AMD processor upgrade procedure can be found after the break.
ORNL's laser-based surveillance / monitoring system takes on RFID
Amazingly, the Oak Ridge National Laboratory (ORNL) is actually not located in the UK, but we wouldn't doubt if the latest development to emerge from its confines somehow ends up across the pond. Nevertheless, scientists at the lab have developed a Laser-Based Item Monitoring System that "addresses surveillance requirements in places where video would be unacceptable because of the presence of proprietary information or other privacy concerns." Essentially, this optical monitoring system uses low-cost reflective tags placed on objects, and then maps the precise location of high-value items to sense tampering. The laser can purportedly detect minute changes (movements of less than a centimeter) by utilizing "a high-resolution two-axis laser scanner capable of looking at a 60-degree field of view in 0.0005-degree increments," meaning that it can divide its field of view into more than 10 billion individual pointing locations. The crew also noted that this system was generally superior to bar code and RFID alternatives as the LBIMS would not be susceptible to jamming or interception, but there's no word just yet on when the Department of Energy (or anyone else) will be putting this stuff to good use.[Via Smartmobs, photo courtesy of Primidi]
