GENCI Receives Honors in 2012 HPCwire Readers’ Choice Award

Posted on 15 November 2012 by Pierre Picard

HPCwire2012GENCI is honored for the “Best use of HPC in edge HPC application” for its contribution using the CURIE bullx supercomputer, for the first full Universe simulation, Observatoire de Paris


Annual HPCwire Awards demonstrate achievements of excellence within the HPC community at the SuperComputing Conference held this year in Salt Lake City, Utah.



Part of the Dark Energy Universe Simulation (DEUS – Full Universe Run) project, the full universe simulation ran on the CURIE supercomputer, owned by Grand Equipement National de Calcul Intensif (GENCI), the French national HPC organization. It is the first calculation of the entire observable Universe, from the Big Bang to the present day. The work entailed the simulation of 550 billion particles. The simulation will aid large projects and observational mapping of our Universe. A key objective is to help gain a better understanding of the nature of dark energy and of its influence on the structure of the Universe, as well as the origin of the distribution of dark matter and galaxies.

The team of researchers from the Laboratoire Univers et Théorie (LUTH, Observatoire de Paris/CNRS/Université Paris Diderot) is directed by Jean-Michel Alimi[1]. The first simulation was completed in April 2012.

The implementation of DEUS was made possible thanks to the powerful resources made available to the researchers by GENCI; most notably, CURIE, a bullx supercomputer with more than 92,000 processors and capable of achieving 2 million billion operations per second (2 Petaflops). Designed by Bull, CURIE is currently one of the most powerful supercomputers in the world. The highly-coveted HPCwire Readers’ Awards hold the unique distinction of being recognized as the most prestigious acknowledgment given by the HPC community to its own each year.
