C /==========================================================\
C | SIZE.h Declare size of underlying computational grid. |
C |==========================================================|
C | The design here support a three-dimensional model grid |
C | with indices I,J and K. The three-dimensional domain |
C | is comprised of nPx*nSx blocks of size sNx along one axis|
C | nPy*nSy blocks of size sNy along another axis and one |
C | block of size Nz along the final axis. |
C | Blocks have overlap regions of size OLx and OLy along the|
C | dimensions that are subdivided. |

C Voodoo numbers controlling data layout.
C sNx - No. X points in sub-grid.
C sNy - No. Y points in sub-grid.
C OLx - Overlap extent in X.
C OLy - Overlat extent in Y.
C nSx - No. sub-grids in X.
C nSy - No. sub-grids in Y.
C nPx - No. of processes to use in X.
C nPy - No. of processes to use in Y.
C Nx - No. points in X for the total domain.
C Ny - No. points in Y for the total domain.
C Nr - No. points in Z for full process domain.
