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 statis-
       tics 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 stan-
       dard 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 compres-
       sion formats which can be supported are the bzip2 format ('.bz2'), the gzip format ('.gz'), and the lzma format ('.lzma', on input only).
