C | The design here supports a three-dimensional model grid |
| 10 |
C | with indices I,J and K. The three-dimensional domain |
| 11 |
C | is comprised of nPx*nSx blocks (or tiles) of size sNx |
| 12 |
C | along the first (left-most index) axis, nPy*nSy blocks |
| 13 |
C | of size sNy along the second axis and one block of size |
| 14 |
C | Nr along the vertical (third) axis. |
| 15 |
C | Blocks/tiles have overlap regions of size OLx and OLy |
| 16 |
C | along the dimensions that are subdivided. |

C Voodoo numbers controlling data layout: |
| 21 |
C sNx :: Number of X points in tile. |
| 22 |
C sNy :: Number of Y points in tile. |
| 23 |
C OLx :: Tile overlap extent in X. |
| 24 |
C OLy :: Tile overlap extent in Y. |
| 25 |
C nSx :: Number of tiles per process in X. |
| 26 |
C nSy :: Number of tiles per process in Y. |
| 27 |
C nPx :: Number of processes to use in X. |
| 28 |
C nPy :: Number of processes to use in Y. |
| 29 |
C Nx :: Number of points in X for the full domain. |
| 30 |
C Ny :: Number of points in Y for the full domain. |
| 31 |
C Nr :: Number of points in vertical direction. |
