Summary of the results from the scalability test (Sect. 3.4.1). Left panel: scaling of the 90% completeness limit (in terms of mass) with the number of particles in the domain. Dashed grey lines correspond to a constant number of particles. Dark red (light red) lines represent the results for the two base grid sizes according to the legend. Middle panel: scaling of the wall time taken by ASOHF with number of particles. Dashed grey lines correspond to a scaling Right panel: scaling of the maximum RAM used ASOHF with number of particles. Dashed grey lines correspond to a constant amount of RAM per particle.
