gtst - test the consistency of source graphs
gtst [options] [gfile] [lfile]
The
gtst program checks, in a sequential way, the consistency of a Scotch
source graph and, in case of success, outputs some statistics regarding edge
weights, vertex weights, and vertex degrees.
It produces the very same results as the
dgtst(1) program of the
PT-Scotch parallel distribution, but unlike this latter it cannot handle
distributed graphs.
Source graph file
gfile can only be a centralized graph file. The
resulting statistics are stored in file
lfile. When file names are not
specified, data is read from standard input and written to standard output.
Standard streams can also be explicitly represented by a dash '-'.
When the proper libraries have been included at compile time,
gtst can
directly handle compressed graphs, both as input and output. A stream is
treated as compressed whenever its name is postfixed with a compressed file
extension, such as in 'brol.grf.bz2' or '-.gz'. The compression formats which
can be supported are the bzip2 format ('.bz2'), the gzip format ('.gz'), and
the lzma format ('.lzma').
