[Conference News] Researchers Simulate Observable Universe

Over the past decades, new cosmological observations have given scientists a clearer picture of the universe. Researchers are looking for ways to conduct simulations using this data.

A French research team presented a paper at the 2012 International Conference for High Performance Computing, Networking, Storage, and Analysis (SC12) in which they reported performing the first-ever numerical N-body simulation of the full observable universe. The simulation entailed 550 billion particles on an adaptive mesh-refinement grid with more than 2 trillion computing points along the entire evolutionary history of the universe and across six order-of-magnitude length scales, from the size of the Milky Way to that of the observable universe.

First-Ever Full Observable Universe Simulation” and other papers from SC12 are available to both IEEE Computer Society members and paid subscribers via the Computer Society Digital Library.

If you don't want to shell out USD 19 for this nicety, it's available at the arxiv, too (totally legit):
