SUMMARY:The Euclid Flagship Simulations
DESCRIPTION:Minisymposium\nComputer Science and Applied Mathematics, Physi
 cs\n\nThe Euclid Flagship Simulations\n\nStadel, Potter\n\nUpcoming large 
 scale structure surveys such as Euclid, DES, LSST, WFIRST will measur
 e the result of billions of years of evolution from the small linear fluct
 uations observed in the Cosmic Microwave Background (CMB). On the ver
 y largest scales these fluctuations are still evolving linearly, but most&
 nbsp;of the leverage on cosmological parameters from these surveys comes f
 rom smaller, highly non-linear scales. Only numerical N-body simulati
 ons capture this non-linear evolution with the required precision. These a
 re, however, very expensive when they must meet the upcoming survey requir
 ements. I will present recent significant advances in our ability to use m
 odern hybrid supercomputers to greatly accelerate these simulations. Of pr
 incipal importance are algorithmic advances as well as optimization of <em
 >all</em> system resources. We have performed two of the World's largest s
 imulations of this type, called the Euclid Flagship Simulations, with 4 <e
 m>trillion</em> (FS2) particles evolving under their own self-gravity. The
 se simulations are used to generate a virtual universe of galaxies that is
  designed to match as closely as possible the expected signal of Euclid, a
 llowing us to quantify all systematics and to assess the performance of th
 e mission in determining the nature of dark matter, dark energy and possib
 le extensions to General Relativity.
