A fine grain modeling of a simulation e.g. by every cell of the simulation domain
can lead to unnecessary communication overhead, since peers are exchanging
possibly more messages than is really necessary.
The solution is a graph partitioning of the communication graph and a unified
communication of these partitions. This should decrease the number of
communication calls between peers while still sticking to fine grain modeling
of the simulation, which is really handy.
