3     C /==========================================================\
4     C | SIZE.h Declare size of underlying computational grid. |
5     C |==========================================================|
6     C | The design here support a three-dimensional model grid |
7     C | with indices I,J and K. The three-dimensional domain |
8     C | is comprised of nPx*nSx blocks of size sNx along one axis|
9     C | nPy*nSy blocks of size sNy along another axis and one |
10     C | block of size Nz along the final axis. |
11     C | Blocks have overlap regions of size OLx and OLy along the|
12     C | dimensions that are subdivided. |
13     C \==========================================================/
14     C Voodoo numbers controlling data layout.
15     C sNx - No. X points in sub-grid.
16     C sNy - No. Y points in sub-grid.
17     C OLx - Overlap extent in X.
18     C OLy - Overlat extent in Y.
19     C nSx - No. sub-grids in X.
20     C nSy - No. sub-grids in Y.
21     C nPx - No. of processes to use in X.
22     C nPy - No. of processes to use in Y.
23     C Nx - No. points in X for the total domain.
24     C Ny - No. points in Y for the total domain.
