gtst - test the consistency of source graphs SYNOPSIS
gtst [options] [gfile] [lfile] DESCRIPTION
The gtst program checks, in a sequential way, the consistency of a Scotch source graph and, in case of success, outputs some statistics regarding edge weights, vertex weights, and vertex degrees. It produces the very same results as the dgtst(1) program of the PT-Scotch parallel distribution, but unlike this latter it cannot handle distributed graphs. Source graph file gfile can only be a centralized graph file. 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 input only). OPTIONS

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 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 input only). OPTIONS

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 target architecture description on the standard input of the gmtst com- mand: $ echo "cmplt num" | gmtst brol.grf - brol.map SEE ALSO
