# acpl(1)

compile a target architectures

## 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.**

## OPTIONS

- **-h**

  **Display some help.**

- **-V**

  **Display program version and copyright.**

## EXAMPLE

**Create a compiled cube-connected-cycle target architecture** **of dimension 4, and save it under the [gzip(1)](/gzip/1.md) 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)](/amk_ccc/1.md) is read from the standard input,** **through the pipe.**

```
    $ amk_ccc 4 | acpl - ccc4c.tgt.gz
```
