13 The acpl program compiles a decomposition-defined target architecture
14 file itfile of type 'deco 0' into a compiled decomposition-defined tar‐
15 get architecture of type 'deco 1', stored in file otfile.
16
17 Compiling a decomposition-defined architecture amounts to computing the
18 distance matrix of all possible subdomains, from the distance matrix of
19 all terminal subdomains provided in the 'deco 0' format. Since this
20 computation is internally performed every time a 'deco 0' format is
21 read, and is quadratic in time, pre-compiling the target architecture
22 by means of acpl can save some time when repeatedly computing mappings
23 on a large decomposition-defined 'deco 0' target architecture.
24
25 When the proper libraries have been included at compile time, acpl can
26 directly handle compressed files, both as input and output. A stream is
27 treated as compressed whenever its name is postfixed with a compressed
28 file extension, such as in 'brol.tgt.bz2' or '-.gz'. The compression
29 formats which can be supported are the bzip2 format ('.bz2'), the gzip
30 format ('.gz'), and the lzma format ('.lzma').
31
32 Since decomposition-defined target architecture files have a size which
33 is quadratic in the number of target vertices, because of the distance
34 matrix structures, using compressed files to store them may save a lot
35 of space, especially for compiled target architecture files.

43 Create a compiled cube-connected-cycle target architecture of dimension
44 4, and save it under the gzip(1) format to file 'ccc4c.tgt.gz'. The
45 dash '-' standard file name is used so that the 'deco 0' target archi‐
46 tecture description produced by amk_ccc(1) is read from the standard
47 input, through the pipe.
