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
