PROGRAM:

NAME


gtst - test the consistency of source graphs

SYNOPSIS


gtst [options] [gfile] [lfile]

DESCRIPTION


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', on input only).

OPTIONS


-h Display some help.

-V Display program version and copyright.

EXAMPLE


Test the consistency of graph brol.grf:

$ gtst brol.grf
