NAME
gmk_hy, gmk_m2, gmk_m3, gmk_ub2  create source graphs
SYNOPSIS
gmk_hy [options] dim [ofile]
gmk_m2 [options] [gcfile] dimX dimY [ofile]
gmk_m3 [options] [gcfile] dimX dimY dimZ [ofile]
gmk_ub2 [options] dim
DESCRIPTION
The
gmk_* programs create source graph files for some common,
regular topologies.
gmk_hy creates a hypercube of dimension dim.
gmk_m2 creates a 2D regular grid of dimensions dimX and dimY.
gmk_m3 creates a 3D regular grid of dimensions dimX, dimY and dimZ.
gmk_ub2 creates an unoriented de Bruijn graph of dimension dim.
OPTIONS
 b base

For gmk_m2 and gmk_m3 only. Output graphs with base
value set to base. Default value is 0.
 e

For gmk_m2 only. Build a 8neighbor grid rather than a
4neighbor grid.
 gcfile

For gmk_m2 and gmk_m3 only. Output graph vertex
coordinates (that is, geometry data to be used by
gout(1)) in file cfile.
 h

Display some help.
 t

For gmk_m2 and gmk_m3 only. Create torus graphs, that
is, graphs such that there exist loop edges between
vertices of rank 0 and (dim1) in every dimension.
 V

Display program version and copyright.
EXAMPLE
Create a 5x7 grid along with its geometry:
$ gmk_m2 5 7 g/tmp/m5x7.xyz /tmp/m5x7.grf
