6 gmtst - compute statistics on mappings

9 gmtst [options] [gfile] [tfile] [mfile] [lfile]
10
13 The gmtst program computes, in a sequential way, statistics on a static
14 mapping, such as load imbalance ratio, edge dilation distribution, etc.
15 It yields the same results as the ones produced by the -vm option of
16 the gmap(1) program.
17 Source graph file gfile can only be a centralized graph file. File
19 tfile represents the target architecture onto which gfile was mapped.
20 If mapping file mfile was produced by gpart(1), the target architecture
21 file to provide gmtst should describe a complete graph with the same
22 number of vertices as the requested number of parts, for instance by
23 means of the 'cmplt num' algorithmically-described architecture. The
24 resulting statistics are stored in file lfile. When file names are not
25 specified, data is read from standard input and written to standard
26 output. Standard streams can also be explicitly represented by a dash
27 '-'.
28 When the proper libraries have been included at compile time, gtst can
30 directly handle compressed graphs, both as input and output. A stream
31 is treated as compressed whenever its name is postfixed with a com‐
32 pressed file extension, such as in 'brol.grf.bz2' or '-.gz'. The com‐
33 pression formats which can be supported are the bzip2 format ('.bz2'),
34 the gzip format ('.gz'), and the lzma format ('.lzma').

42 Display statistics on mapping brol.map of graph brol.grf onto target
43 architecture brol.tgt:
44 $ gmtst brol.grf brol.tgt brol.map
46 Display statistics on partitioning brol.map of graph brol.grf into num
48 parts. Note the use of the complete graph algorithmically-described ar‐
49 chitecture and of the shell pipe command to provide the complete target
50 architecture description on the standard input of the gmtst command:
51 $ echo "cmplt num" | gmtst brol.grf - brol.map
