Recent versions of scotch are rarely available in packaged form for ready installation on GNU/Linux distributions and so the sources are generally required.

\fBgtst \fP- test the consistency of source graphs

.SH DESCRIPTION
|
|
The \fBgtst\fP 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.
|
|
.PP
|
|
It produces the very same results as the \fBdgtst\fP(1) program of the
|
|
PT-Scotch parallel distribution, but unlike this latter it cannot
|
|
handle distributed graphs.
|
|
.PP
|
|
Source graph file \fIgfile\fP can only be a centralized graph file. The
|
|
resulting statistics are stored in file \fIlfile\fP. 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 '-'.
|
|
.PP
|
|
When the proper libraries have been included at compile time, \fBgtst\fP
|
|
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).
