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.
IBM's Mira supercomputer tasked with simulating an entire universe in a fortnight
A universe that only exists in the mind of a supercomputer sounds a little far fetched, but one is going to come to live at the Argonne National Laboratory in October. A team of cosmologists is using IBM's Blue Gene/Q "Mira" supercomputer, the third fastest in the world, to run a simulation through the first 13 billion years after the big bang. It'll work by tracking the movement of trillions of particles as they collide and interact with each other, forming structures that could then transform into galaxies. As the project's only scheduled to last a fortnight, we're hoping it doesn't create any sentient characters clamoring for extra life, we've seen Blade Runner enough times to know it won't end well.
IBM's Mira supercomputer does ten petaflops with ease, inches us closer to exascale-class computing
Say hello to the Blue Gene/Q, or if you're looking for something a bit less intimidating, "Mira." That's IBM's latest and greatest concoction, a ten-petaflop supercomputer capable of running programs at ten quadrillion calculations a second. Hard to say who'd win between Mira and Watson, of course, but there's absolutely no question who'd come out on top if Mira were pitted against her predecessor Intrepid (hint: Mira's 20x faster). To put this all in perspective, IBM's chiming in with this: "If every man, woman and child in the United States performed one calculation each second, it would take them almost a year to do as many calculations as Mira will do in one second." Mira's next stop is at the US Department of Energy's Argonne National Laboratory, where it'll be used to tackle 16 projects in particular that were drawn from a pool of proposals to gain access to her capabilities. We're told that these include a range of initiatives -- from reducing energy inefficiencies in transportation and developing advanced engine designs to spurring advances in energy technologies -- and in time, it could lead to exascale-class computers "that will be faster than petascale-class computers by a factor of a thousand." And here we are getting excited about a 5GHz Core i7.
