NAME
     gmtst - compute statistics on mappings

SYNOPSIS
     gmtst [options] [gfile] [tfile] [mfile] [lfile]

DESCRIPTION
     The  gmtst  program  computes,  in a sequential way, statistics on a static
     mapping, such as load imbalance ratio, edge dilation distribution, etc.  It
     yields  the  same	results  as  the  ones produced by the -vm option of the
     gmap(1) program.

     Source graph file gfile can only be a centralized graph  file.  File  tfile
     represents  the target architecture onto which gfile was mapped. If mapping
     file mfile was produced by gpart(1), the target architecture file	to  pro-
     vide  gmtst  should  describe a complete graph with the same number of ver-
     tices as the requested number of parts, for instance by means of the 'cmplt
     num' algorithmically-described architecture. 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  di-
     rectly  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.

EXAMPLES
     Display statistics on mapping brol.map of graph brol.grf onto target archi-
     tecture brol.tgt:

	 $ gmtst brol.grf brol.tgt brol.map

     Display statistics on partitioning brol.map  of  graph  brol.grf  into  num
     parts.  Note the use of the complete graph algorithmically-described archi-
     tecture and of the shell pipe command to provide the complete target archi-
     tecture description on the standard input of the gmtst command:

	 $ echo "cmplt num" | gmtst brol.grf - brol.map
