fortran code to setup topology is now part of pkg/exch2, with new parameter 
6 
file "data.exch2". 
7 
None of the modified src file (from any sub.dir) is necessary (just SIZE.h 
8 
is enough) and therefore has not been updated. No additional parameter 
9 
is needed (can run without "data.exch2", using the default), except for 
10 
the last case (s176t_8x4) with blank tiles: data.exch2.16_blk 
11 
An other example with blanktiles can be foundi in: 
12 
verification/adjusment.cs32x32x1/input/data.exch2.mpi

Example of modified src code (from matlabtopologygenerator) corresponding 
16 
to different tiling of regular CS32 grid: 
17 

18 
 s6t_32x32 : 6 tiles, dimension of each tile: 32 x 32 ( 1x1 tile per face) 
19 
 s12t_16x32 : 12 tiles, dimension of each tile: 16 x 32 ( 2x1 tile per face) 
20 
 s12t_32x16 : 12 tiles, dimension of each tile: 32 x 16 ( 1x2 tile per face) 
21 
 s24t_16x16 : 24 tiles, dimension of each tile: 16 x 16 ( 2x2 tile per face) 
22 
 s24t_32x8 : 24 tiles, dimension of each tile: 32 x 8 ( 1x4 tile per face) 
23 
 s24t_8x32 : 24 tiles, dimension of each tile: 8 x 32 ( 4x1 tile per face) 
24 
 s192t_8x4 : 192 tiles, dimension of each tile: 8 x 4 ( 4x8 tile per face) 
25 
 s176t_8x4 : 176 tiles, same as s192t_8x4 with 16 blanktiles
