Sequoia supercomputer breaks simulation speed record, 41 times over
While we've seen supercomputers break records before, rarely have we seen the barrier smashed quite so thoroughly as by Lawrence Livermore National Laboratory's Sequoia supercomputer. Researchers at both LLNL and Rensselaer Polytechnic Institute have used planet-scale calculations on the Blue Gene/Q-based cluster to set an all-time simulation speed record of 504 billion events per second -- a staggering 41 times better than the 2009 record of 12.2 billion. The partnership also set a record for parallelism, too, by making the supercomputer's 1.97 million cores juggle 7.86 million tasks at once. If there's a catch to that blistering performance, it's not knowing if Sequoia reached its full potential. LLNL and RPI conducted their speed run during an integration phase, when Sequoia could be used for public experiments; now that it's running classified nuclear simulations, we can only guess at what's possible.
Stanford seizes 1 million processing cores to study supersonic noise
In short order, the Sequoia supercomputer and its 1.57 million processing cores will transition to a life of top-secret analysis at the National Nuclear Security Administration, but until that day comes, researchers are currently working to ensure its seamless operation. Most recently, a team from Stanford took the helm of Sequoia to run computational fluid dynamics simulations -- a process that requires a finely tuned balance of computation, memory and communication components -- in order to better understand engine noise from supersonic jets. As an encouraging sign, the team was able to successfully push the CFD simulation beyond 1 million cores, which is a first of its kind and bodes very well for the scalability of the system. This and other tests are currently being performed on Sequoia as part of its "shakeout" period, which allows its caretakers to better understand the capabilities of the IBM BlueGene/Q computer. Should all go well, Sequoia is scheduled to begin a life of government work in March. In the meantime, you'll find a couple views of the setup after the break.

Google brings five California-based US National Parks into Street View
Taking a virtual tour of the Amazon or Antarctica? Totally doable with Street View. But some of America's finest National Parks? Yeah, those have been a long time coming. Today, Google announced the inclusion of five California-based US National Parks in Street View, and for those who haven't had the opportunity (of a lifetime) to visit, they're absolutely worth a look. Starting at the top, Redwoods National Park provides a street level look at some of the world's most mysterious trees, while those looking for even more Treebeard-type characters can point their browser to Sequoia & Kings Canyon National Parks. Naturally, Yosemite and Joshua Tree (shown above) are included as well, and the 360-degree views Google's cadre of motorcars managed to capture really do a fairly astounding job at capturing the splendor. The toughest part? Knowing which one to traverse first.
