Largest-Ever Simulation of the Universe Revealed - Technology Review
The latest computer model of the cosmos involves 400 billion particles in a box about two thirds of the volume of the universe
… Today, Juhan Kim at the Korea Institute for Advanced Study in Seoul, and a few pals, show just how far this technique has come. These guys have carried out the largest simulation of the universe ever undertaken, consisting of 374 billion particles in a box some 10 gigaparsecs across. That’s roughly equivalent to about two thirds the size of the observable universe.
This took some 20 days of computing time on the Tachyonii supercomputer in Korea, the 26th fastest in the world in the last set of rankings.
