✨ gmtst ✨

so like… this is page gmtst(1) from the Scotch user's manual and bestie it's a whole vibe 💅 buckle up

🎀 NAME 🎀

gmtst — compute statistics on mappings

🦋 SYNOPSIS 🦋

gmtst [options] [gfile] [tfile] [mfile] [lfile]

🌸 DESCRIPTION 🌸

okay so the tea is that gmtst computes, in a sequential way, statistics on a static mapping. we're talking load imbalance ratio, edge dilation distribution, etc. 📊 and it literally yields the same results as the ones produced by the -vm option of the gmap(1) program. same numbers, different doorway, iykyk 🫶

the source graph file gfile can only be a centralized graph file — no cap, that's the rule. file tfile represents the target architecture onto which gfile was mapped. and here's the part where you gotta pay attention bestie 👀: if mapping file mfile was produced by gpart(1), the target architecture file you hand to 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 get stored in file lfile. and 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 '-' 💖

and now the fun part: 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'). iconic 🗜️

💜 OPTIONS 💜

  • -h — Display some help. (your lil safety net 🫶)
  • -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 target architecture description on the standard input of the gmtst command — pipes are the moment fr fr:

$ echo "cmplt num" | gmtst brol.grf - brol.map
