C !ROUTINE: SIZE.h
C !INTERFACE:
C include SIZE.h
C !DESCRIPTION: \bv
C *==========================================================*
C | SIZE.h Declare size of underlying computational grid.
C *==========================================================*
C | The design here supports a three-dimensional model grid
C | with indices I,J and K. The three-dimensional domain
C | is comprised of nPx*nSx blocks (or tiles) of size sNx
C | along the first (left-most index) axis, nPy*nSy blocks
C | of size sNy along the second axis and one block of size
C | Nr along the vertical (third) axis.
C | Blocks/tiles have overlap regions of size OLx and OLy
C | along the dimensions that are subdivided.
C *==========================================================*

C Voodoo numbers controlling data layout:
C sNx :: Number of X points in tile.
C sNy :: Number of Y points in tile.
C OLx :: Tile overlap extent in X.
C OLy :: Tile overlap extent in Y.
C nSx :: Number of tiles per process in X.
C nSy :: Number of tiles per process in Y.
C nPx :: Number of processes to use in X.
C nPy :: Number of processes to use in Y.
C Nx :: Number of points in X for the full domain.
C Ny :: Number of points in Y for the full domain.
C Nr :: Number of points in vertical direction.
