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 provide gmtst should describe a complete graph with the same number of vertices as
the requested number of parts, for instance by means of the 'cmpltnum' 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 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').
