Box partition

Each partition is a rectangular region of the global domain, described by the global offset of its upper left corner, and its local extents in the X and Y dimensions. The global extent in the X dimension must also be given. In this case, we have ig_paral(1:5):

Figure [*] illustrates a Box partition over 3 processes.
