NAME

6       gmk_hy, gmk_m2, gmk_m3, gmk_ub2 - create source graphs
7

SYNOPSIS

9       gmk_hy [options] dim [ofile]
10
11       gmk_m2 [options] [-gcfile] dimX dimY [ofile]
12
13       gmk_m3 [options] [-gcfile] dimX dimY dimZ [ofile]
14
15       gmk_ub2 [options] dim
16

DESCRIPTION

18       The  gmk_*  programs create source graph files for some common, regular
19       topologies.
20
21       gmk_hy creates a hypercube of dimension dim.
22
23       gmk_m2 creates a 2D regular mesh of dimensions dimX and dimY.
24
25       gmk_m3 creates a 3D regular mesh of dimensions dimX, dimY and dimZ.
26
27       gmk_ub2 creates an unoriented de Bruijn graph of dimension dim.

OPTIONS

30       -b base
31              For gmk_m2 and gmk_m3 only. Output graphs with base value set to
32              base. Default value is 0.
33
34       -e     For  gmk_m2 only. Build a 8-neighbor grid rather than a 4-neigh‐
35              bor grid.
36
37       -gcfile
38              For gmk_m2 and gmk_m3  only.  Output  graph  vertex  coordinates
39              (that is, geometry data to be used by gout(1)) in file cfile.
40
41       -h     Display some help.
42
43       -t     For gmk_m2 and gmk_m3 only. Create torus graphs, that is, graphs
44              such that there exist loop edges between vertices of rank 0  and
45              (dim-1) in every dimension.
46
47       -V     Display program version and copyright.

EXAMPLE

50       Create a 5x7 grid along with its geometry:
51
52             $ gmk_m2 5 7 -g/tmp/m5x7.xyz /tmp/m5x7.grf
