gmtst(1) Scotch user's manual gmtst(1)NAMEgmtst - compute statistics on mappings
SYNOPSISgmtst [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 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 com‐
pressed file extension, such as in 'brol.grf.bz2' or '-.gz'. The com‐
pression 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
architecture 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
architecture and of the shell pipe command to provide the complete tar‐
get architecture description on the standard input of the gmtst com‐
mand:
$ echo "cmplt num" | gmtst brol.grf - brol.map
