 The initial distribution of particles used in our tests is extracted and
 resampled from low-redshift outputs of the EAGLE project \cite{Schaye2015}, a
 large suite of state-of-the-art cosmological simulations. By selecting outputs
-at late times, we constructed a simulation setup which is representative of the

-highly-clustered and no longer uniformly distributed. This distribution of

 100 time-steps and average the wall clock time of these time-steps after having
