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 8-neighbor grid rather than a 4-neighbor 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 (dim-1) 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
