Detailed Description

Manage the partitioning of the domain.

This routine achieves a new partitioning of the grid where most of unused cells are discarded for the linear resolution

Coordinates of each process are set again, as well as neighbor process numbers in the new partitioning.

Finally, the routine computes for each process the number of processes to exchange.
