gmk_hy(1) Scotch user's manual gmk_hy(1)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 8-neighbor grid rather than a 4-neighâ
bor 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
