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.
