NAME

6       gtst - test the consistency of source graphs
7

SYNOPSIS

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

DESCRIPTION

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