NAME

gmk_hy, gmk_m2, gmk_m3, gmk_ub2 - create source graphs

SYNOPSIS

gmk_hy [ options ] dim [ ofile ]

gmk_m2 [ options ] [ -g cfile ] dimX dimY [ ofile ]

gmk_m3 [ options ] [ -g cfile ] 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.

-g cfile

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
