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’).

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
