gmtst - compute statistics on mappings
gmtst [options] [gfile] [tfile] [mfile] [lfile]
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 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 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, on

Display statistics on mapping brol.map of graph brol.grf onto target
$ 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 architecture and of the shell pipe command
to provide the complete target architecture description on the
standard input of the gmtst command:
$ echo "cmplt num" | gmtst brol.grf - brol.map
gmap(1), gout(1), gtst(1).
