How does the processor distrib react to a change in change_box

Hi Everyone,

For my simulations I'm slowly growing the simulation domain using a change_box command with scaling in the z direction.

The docs tell me that "the mapping of processors to the simulation box is not changed from its initial 3d configuration".

Does this mean that the processors on the z boundaries of the domain get the extra simulation domain? If so, is there a clever way to perform a "fools" load balancing step?

Thanks in advance,

Victor
