18 C--- Size of Tiling topology structures
19 C W2_maxNbFacets :: Maximum number of Facets (also and formerly called
20 C :: "domains" or "sub-domains") of this topology.
21 C W2_maxNeighbours :: Maximum number of neighbours any tile has.
22 C W2_maxNbTiles :: Maximum number of tiles (active+blank) in this topology
23 C W2_ioBufferSize :: Maximum size of Single-CPU IO buffer.
24 INTEGER W2_maxNbFacets
25 INTEGER W2_maxNeighbours
26 INTEGER W2_maxNbTiles
27 INTEGER W2_ioBufferSize
28 INTEGER W2_maxXStackNx
29 INTEGER W2_maxXStackNy
30 INTEGER W2_maxYStackNx
31 INTEGER W2_maxYStackNy
32
33 C--- Default values :
34 C (suitable for 6-face Cube-Sphere topology, compact global I/O format)
35 C W2_maxNbTiles = Nb of active tiles (=nSx*nSy*nPx*nPy) + Max_Nb_BlankTiles
36 C default assume a large Max_Nb_BlankTiles equal to Nb of active tiles
37 C resulting in doubling the tile number.
38 PARAMETER ( W2_maxNbFacets = 10 )
39 PARAMETER ( W2_maxNeighbours = 8 )
40 PARAMETER ( W2_maxNbTiles = nSx*nSy*nPx*nPy * 2 )
41 PARAMETER ( W2_ioBufferSize = W2_maxNbTiles*sNx*sNy )
42 PARAMETER ( W2_maxXStackNx = W2_maxNbTiles*sNx )
43 PARAMETER ( W2_maxXStackNy = W2_maxNbTiles*sNy )
44 PARAMETER ( W2_maxYStackNx = W2_maxNbTiles*sNx )
45 PARAMETER ( W2_maxYStackNy = W2_maxNbTiles*sNy )
46
47 C- Note: Overestimating W2_maxNbFacets and, to less extent, W2_maxNeighbours
48 C have no or very little effects on memory footprint.
49 C overestimated W2_maxNbTiles does not have large effect, except
50 C through ioBufferSize (if related to, as here).
