NAME

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

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]

DESCRIPTION

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

OPTIONS

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

EXAMPLE

51       Create a 5x7 grid along with its geometry:
52
53           $ gmk_m2 5 7 -g/tmp/m5x7.xyz /tmp/m5x7.grf
54
