"for sure" is a bit of an overbid :) If the overall cost is dominated by
computation over the range of N of interest, then the scaling properties of
the computation will dominate the overall scaling.

Refs 11 and 12 from section 4.9.2 of the manual have the kind of content
you are seeking, IIRC.

Hi Andrew,
maybe it is true on single processor simulations.
It is false for sure when we talk about multicpu simulations because in
this case each cpu has
comunicate with each other and the implementations of this step makes a
huge difference between
the different codes.

Hi,
Please forgive me for this slightly off-topic question. Suppose I use the
particle mesh Ewald algorithm for the computation of electrostatic
interactions. It is often mentioned in the literature that the PME
algorithm scales as O(N logN), and that the electrostatic interactions are
the most
