A team of researchers from the Laboratoire Univers et Théorie has performed the first-ever computer model simulation of the structuring of the entire observable universe, from the Big Bang to the present day. Using GENCI’s new supercomputer CURIE, this unprecedented simulation followed the evolution of 550 billion particles, which will shed light on the nature of dark energy and its effects on cosmic structure formation, and hence on the distribution of dark matter and galaxies in the universe.
The implementation of this exceptional project would not have been possible without the powerful resources made available to the researchers by the “Grand Equipement National de Calcul Intensif ” (GENCI), whose new supercomputer CURIE is equipped with more than 92,000 CPUs and can perform 2 Petaflops. The CURIE supercomputer is housed and operated by the CEA at the ” Très Grand Centre de Calcul, at Bruyères-le-Châtel (Essonne). Designed by Bull, it is one of the world’s five most powerful supercomputers.
