I'm not just describing strong scaling. I'm describing a cost-effective way to achieve it; that's what really matters.
Why have subsets of nodes for post-simulation cleanup? Why not just run that cleanup on the same nodes you used for simulation? Or other general nodes? Otherwise, you've got two sets of nodes which are used at lower utilization than they would normally be.
