0006 C *==========================================================*
0007 C | SIZE.h Declare size of underlying computational grid.
0008 C *==========================================================*
0009 C | The design here supports a three-dimensional model grid
0010 C | with indices I,J and K. The three-dimensional domain
0011 C | is comprised of nPx*nSx blocks (or tiles) of size sNx
0012 C | along the first (left-most index) axis, nPy*nSy blocks
0013 C | of size sNy along the second axis and one block of size
0014 C | Nr along the vertical (third) axis.
0015 C | Blocks/tiles have overlap regions of size OLx and OLy
0016 C | along the dimensions that are subdivided.

0023 C OLx :: Tile overlap extent in X.
0024 C OLy :: Tile overlap extent in Y.
0025 C nSx :: Number of tiles per process in X.
0026 C nSy :: Number of tiles per process in Y.
0027 C nPx :: Number of processes to use in X.
0028 C nPy :: Number of processes to use in Y.
0029 C Nx :: Number of points in X for the full domain.
