NAME

       acpl - compile a target architectures

SYNOPSIS

       acpl [options] [itfile] [otfile]

DESCRIPTION

       The acpl program compiles a decomposition-defined target architecture file itfile of type 'deco 0' into a
       compiled decomposition-defined target architecture of type 'deco 1', stored in file otfile.

       Compiling  a  decomposition-defined architecture amounts to computing the distance matrix of all possible
       subdomains, from the distance matrix of all terminal subdomains provided in the 'deco 0'  format.   Since
       this  computation is internally performed every time a 'deco 0' format is read, and is quadratic in time,
       pre-compiling the target architecture by means of acpl can  save  some  time  when  repeatedly  computing
       mappings on a large decomposition-defined 'deco 0' target architecture.

       When  the proper libraries have been included at compile time, acpl 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).

       Since  decomposition-defined  target  architecture  files have a size which is quadratic in the number of
       target vertices, because of the distance matrix structures, using compressed files to store them may save
       a lot of space, especially for compiled target architecture files.

EXAMPLE

       Create a compiled cube-connected-cycle target architecture of dimension 4, and save it under the  gzip(1)
       format  to  file  'ccc4c.tgt.gz'.  The  dash  '-'  standard file name is used so that the 'deco 0' target
       architecture description produced by amk_ccc(1) is read from the standard input, through the pipe.

           $ amk_ccc 4 | acpl - ccc4c.tgt.gz
