NAME

       atst - test the consistency of target architectures

SYNOPSIS

       atst [options] [afile] [lfile]

DESCRIPTION

       The  atst  program  checks  the consistency of a Scotch decomposition-defined target architecture and, in
       case of success, outputs some statistics regarding the number of target vertices and the length of  paths
       linking  them.  Target  architectures  define  the  topology  of the target graphs used by static mapping
       programs gmap(1) and dgmap(1).

       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, atst can directly handle compressed  files,
       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.tgt.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).
