Notes. Each row corresponds to a particular test, characterised by the number of particles (Npart) and the base grid size (Nx). For each Npart, the mass function is truncated at 
and 
are thus generated. For each run, we report the number of haloes detected by AS0HF (
), the 90% completeness limit (in mass and number of particles;
and 
respectively), the execution (wall) time and the peak RAM usage. The last column gives the peak RAM per particle.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
