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.
DECam: Gazing deep into the final frontier in search of dark energy
The National Optical Astronomy Observatory (NOAO) puts it into perspective right away: "Eight billion years ago, rays of light from distant galaxies began their long journey to Earth." It's important to hold that fact in mind, as we marvel at the first images from deep in the belly of our universe to arrive from the Chile-based Dark Energy Camera (DECam). As that name might suggest, peering at remote galaxies for purely visual gratification isn't the camera's primary purpose. The result of eight years of planning and hard work, involving engineers and scientists from three continents, the DECam is mounted on the Victor M. Blanco Telescope at the Cerro Tololo Inter-American Observatory in Chile. Sitting atop a 7,200-foot mountain, the camera is part of the Dark Energy Survey, which intends to gather information on over 300 million galaxies. The goal is to better understand dark energy -- a concept that represents our best explanation for why the universe's rate of expansion is speeding up, rather than slowing due to gravity. Gaze past the break for the background on the project.
IBM and NCSA end their Blue Waters affair, go back to just being supercomputing friends
It seems that IBM and the National Center for Supercomputing Applications at the University of Illinois have hit a snag in their once fruitful relationship. After nearly four years of partnering for the Blue Waters petascale supercomputer, the NCSA's recently released a joint statement explaining that IBM's "terminated" its involvement with the project. If you'll recall, IBM was supplying its latest Power7 rigs to get all that data flowing, but the company's now decided that Ol' Blue will require more resources than initially anticipated. Apparently, there were talks to try and keep the spark alive, but since those fell through both have decided to return each others CDs and hoodies assets involved with the project (per contract terms): IBM gives back the money, while the NCSA returns any hardware supplied. The two plan on remaining in touch for future endeavours, and the NCSA doesn't appear to be too down either as it'll be consulting with the National Science Foundation to keep Blue Waters afloat. You'll find the official statement in the source link below, but we've included a video rendition of how we'd like to imagine it past the break. [Photo credit: kosheahan]
NCSA prepares for Blue Waters petascale supercomputer, and we've got the video to prove it
How often do you get to see an unboxing of this magnitude? Our buddy Bill at the NCSA (National Center for Supercomputing Applications at the University of Illinois) has been kind enough to hit us up with a video that shows the arrival and installation of the facility's new IBM 780 hardware at the National Petascale Computing Facility. This hardware will allow scientists to prep code in anticipation of the Blue Waters -- which, as previously reported, will be the largest publicly accessible supercomputer in the world when it goes online in 2011, thanks to its over 16,000 Power7 nodes.
