Weak scaling comparison of phew using 1,024 tasks to find structure in a \(\pmb{512^{3}}\) and a \(\pmb{1{,}024^{3}}\) particle cosmological box. The phew runtimes for the \(1{,}024^{3}\) box are divided by a factor of 8 for comparison with the runtimes for the 5123 box. Increasing the size of the dataset improves the scaling of phew for large numbers of MPI tasks.
