NAME

6       gtst - test the consistency of source graphs
7

SYNOPSIS

9       gtst [options] [gfile] [lfile]
10
11

DESCRIPTION

13       The  gtst  program  checks,  in  a sequential way, the consistency of a
14       Scotch source graph and, in case of success,  outputs  some  statistics
15       regarding edge weights, vertex weights, and vertex degrees.
16
17       It  produces  the  very same results as the dgtst(1) program of the PT-
18       Scotch parallel distribution, but unlike this latter it  cannot  handle
19       distributed graphs.
20
21       Source  graph  file gfile can only be a centralized graph file. The re‐
22       sulting statistics are stored in file lfile. When file  names  are  not
23       specified,  data  is  read  from standard input and written to standard
24       output. Standard streams can also be explicitly represented by  a  dash
25       '-'.
26
27       When  the proper libraries have been included at compile time, gtst can
28       directly handle compressed graphs, both as input and output.  A  stream
29       is  treated  as  compressed  whenever its name is postfixed with a com‐
30       pressed file extension, such as in 'brol.grf.bz2' or '-.gz'.  The  com‐
31       pression  formats which can be supported are the bzip2 format ('.bz2'),
32       the gzip format ('.gz'), and the lzma format ('.lzma').
