gtst(1) Scotch user's manual gtst(1)NAMEgtst - test the consistency of source graphs
SYNOPSISgtst [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 com‐
pressed file extension, such as in 'brol.grf.bz2' or '-.gz'. The com‐
pression 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

$ gtst brol.grf
