Running many quick cosmological simulations

A large number of cosmological simulations is important for evaluating
uncertainties in large-scale structure measurements. I present recent
methods of quick large-scale structure simulations, and my work
of generating 600 realisations of mock galaxy catalogues for the
WiggleZ Dark Energy Survey using the COmoving Lagrangian Acceleration
(COLA) method. This simulation method can compute large-scale
structure reasonably well with only 10 time steps. With these mock
catalogs, we updated the Baron Acoustic Oscillation (BAO) cosmic
distance measurement improved by the 'reconstruction' technique.
