The first simulation of the full observable universe has been completed by the DEUS team using 76056 cores of Curie Thin (80000 CPUs) supercomputer of the GENCI agency at TGCC center in France. The project has been selected among other grand-challenges in all domain of computational science by the PRACE call for tier-0 machines. The simulation has followed the evolution of 550 billion particles in a 21 Gpc/h simulation box for a concordance LCDM model. To realize this immense simulation the DEUS team has used at its extreme capacity Curie Thin designed by Bull. This run, which is the first out of three expected by the project, has produce 1.2 Petabytes of data, which consist of full-sky light cones (constructed without replica) from z=0 to z=30, 15 snapshots at several redshifts and a subsample of 2 Gpc/h at every coarse integration time step. A preliminary analysis has shown that at z=0 the Universe should not contain more than 6 clusters with mass larger than 10^15 solar masses.
To date, this is the largest cosmological simulations ever run.
