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

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.
