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).

OPTIONS
