DEUS Full Observable {\Lambda}CDM Universe Simulation: the numerical
  challenge
  We have performed the first-ever numerical N- body simulation of the full
observable universe (DEUS "Dark Energy Universe Simulation" FUR "Full Universe
Run"). 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 order of magnitudes length scales, from
the size of the Milky Way to that of the whole observable universe. To date,
this is the largest and most advanced cosmological simulation ever run. It
provides unique information on the formation and evolution of the largest
structure in the universe and 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 more than 300 TB of memory for 10 million hours of
computing time. About 50 PBytes of data were generated throughout the run.
Using an advanced and innovative reduction workflow the amount of useful stored
data has been reduced to 500 TBytes.
