The Illustris project is an international collaboration of scientists to simulate galaxy formation in the universe since the Big Bang in a comprehensive physical computer model based on the latest scientific information.[1][2][3][4][5][6][7]


A large-scale structure simulation of the universe - similar to the Illustris project.

The Illustris project includes large-scale cosmological simulations of the evolution of the Universe, spanning initial conditions of the Big Bang, to the present day, 13.8 billion years later. Modeling, based on the most precise data and calculations currently available, are compared to actual findings of the observable universe in order to better understand the nature of the universe, including galaxy formation, dark matter and dark energy.[1][2][3][4][5][6][7]

Computational Resources[edit]

The main Illustris simulation was run on the Curie supercomputer at CEA (France), the SuperMUC supercomputer at the Leibniz Computing Center (Germany) and a supercomputer at MIT (United States).[1][8] A total of 19 million CPU hours was required, using 8,192 CPU cores.[1] The peak memory usage was approximately 25 TB of RAM.[1] A total of 136 snapshots were saved over the course of the simulation, totaling over 230 TB cumulative data volume.[2]
