http://www.theatlantic.com/technolog...verses/262639/Next month, one of the world's fastest supercomputers will run the largest, most complex universe simulation ever attempted.
Mira is powered by 768,000 cores spread across 48 blade racks. It has eight petaflops of processing power, and at its peak theoretical performance is able to perform 10 quadrillion floating point operations per second. Oh, and it has nearly a petabyte of RAM.
The simulation will cram more than 12 billion years worth of cosmic evolution into just two weeks, tracking trillions of particles as they slowly coalesce into the web-like structure that defines our universe on a large scale. Cosmic simulations have been around for decades, but the technology needed to run a trillion-particle simulation only recently became available.
