Top: Nemesis bridge time step δtnem versus computation time for an identical cluster containing 20 subsystems. Blue points correspond to a cluster with density ρ ~ 103 M⊙ pc−3, while red and purple points ρ ~ 102 M⊙ pc−3. Dashed lines indicate curves with exponent α = −0.5. Bottom: number of children Nchd versus time taken to simulate an identical cluster to 100 kyr, tsim.
