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.
25 C Nr - No. points in R for full process domain.
