Pleiades Generated The Largest and Most Realistic Simulations of Evolving Universe

With the help of NASA’s powerful supercomputer with the name Pleiades scientists have generated the largest and most realistic simulations of the evolving universe to date. By running the Bolshoi simulation code on Pleiades, researchers hope to explain how galaxies and other very large structures in the universe have changed since the Big Bang 13.7 billion years ago. The Bolshoi code took 18 days and millions of hours of computer time split up among more than 160,000 processors to finish running on Pleiades, which is the seventh most powerful supercomputer in the world. Bolshoi universe simulation, which is the most realistic view of the universe to date, was released in late September 2011.

The Bolshoi simulation code is designed to model the distribution of dark matter across a span of one billion light years. Dark matter is matter that neither emits nor scatters light or other electromagnetic radiation.
