First-Ever Full Observable Universe Simulation

SESSION: Cosmology Applications

EVENT TYPE: Papers

TIME: 10:30AM - 11:00AM

SESSION CHAIR: Subhash Saini

AUTHOR(S):Jean-Michel Alimi, Vincent Bouillot, Yann Rasera, Vincent Reverdy, Pier-Stefano Corasaniti, Irène Balmès, Stéphane Requena, Xavier Delaruelle, Jean-Noël Richet

ROOM:255-EF

ABSTRACT:
We performed a massive N-body simulation of the full observable universe. This has evolved 550 billion particles on an Adaptive Mesh Refinement grid with more than two trillion computing points along the entire evolutionary history of the Universe, and across 6 orders of magnitudes length scales, from the size of the Milky Way to the whole observable Universe. To date, this is the largest and most advanced cosmological simulation ever run. It will have a major scientific impact and provide an exceptional support to future observational programs dedicated to mapping the distribution of matter and galaxies in the Universe. The simulation has run on 4752 (of 5040) thin nodes of BULL supercomputer CURIE, using 300 TB of memory for 10 million hours of computing time. 50 PBytes of rough data were generated throughout the run, reduced to a useful amount of 500 TBytes using an advanced and innovative reduction workflow.
