NAME

6       atst - test the consistency of target architectures
7

SYNOPSIS

9       atst [options] [afile] [lfile]
10

DESCRIPTION

12       The  atst  program  checks  the  consistency of a Scotch decomposition-
13       defined target architecture and, in case of success, outputs some  sta‐
14       tistics regarding the number of target vertices and the length of paths
15       linking them. Target architectures define the topology  of  the  target
16       graphs used by static mapping programs gmap(1) and dgmap(1).
17
18       The  resulting statistics are stored in file lfile. When file names are
19       not specified, data is read from standard input and written to standard
20       output.  Standard  streams can also be explicitly represented by a dash
21       '-'.
22
23       When the proper libraries have been included at compile time, atst  can
24       directly handle compressed files, both as input and output. A stream is
25       treated as compressed whenever its name is postfixed with a  compressed
26       file  extension,  such  as in 'brol.tgt.bz2' or '-.gz'. The compression
27       formats which can be supported are the bzip2 format ('.bz2'), the  gzip
28       format ('.gz'), and the lzma format ('.lzma', on input only).
