NAME

7       atst - test the consistency of target architectures
8

SYNOPSIS

10       atst [options] [afile] [lfile]
11

DESCRIPTION

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