NAME

       amk_ccc, amk_fft2, amk_hy, amk_m2, amk_p2 - create target architectures

SYNOPSIS

       amk_ccc [options] dim [tfile]

       amk_fft2 [options] dim [tfile]

       amk_hy [options] dim [tfile]

       amk_m2 [options] dimX [dimY] [tfile]

       amk_p2 [options] [wght0] [wght1] [tfile]

DESCRIPTION

       The amk_* programs create target architecture files for some common, regular topologies.

       amk_ccc creates a decomposition-defined cube-connected-cycle topology of dimension dim. The decomposition
       is performed first by bisection along the dimensions of the hypercube, then  along  the  remaining  cycle
       graphs.

       amk_fft2   creates   a  decomposition-defined  fast-Fourier-transform  topology  of  dimension  dim.  The
       decomposition is performed by recursive bisection of the vertices, by descending dimension (that is,  bit
       number in the labeling of the vertices).

       amk_hy  creates  a  decomposition-defined  hypercube  topology  of  dimension  dim.  The decomposition is
       performed by recursive bisection of the vertices, by descending dimension (that is,  bit  number  in  the
       labeling  of  the  vertices).  Save  for  experimentation  purposes,  this  program is deprecated, as the
       algorithmically-defined 'hcub' target architecture is a more convenient and efficient  way  to  represent
       hypercube architectures.

       amk_m2  creates  a  decomposition-defined  2D  regular  grid  topology  of  dimensions dimX and dimY. The
       decomposition is performed by recursive splitting along the dimensions, either  by  cutting  the  longest
       one, or by one-way dissection, depending on the '-m' option flag. Save for experimentation purposes, this
       program is deprecated, as the algorithmically-defined 'mesh2D' and 'mesh3D' target  architectures  are  a
       more convenient and efficient way to represent 2D and 3D grid architectures.

       amk_p2  creates  a  weighted path graph topology comprising only two vertices of weights wght0 and wght1.
       This is just a helper program, which builds a 'wcmplt' algorithmically-defined complete  graph  with  two
       vertices. It may be used to compute weighted bisections of a graph.

OPTIONS

       -mmeth For amk_m2 only. Perform either recursive dissection or one-way dissection, according to the given
              method flag:

              n      perform nested dissection (default).

              o      perform one-way dissection (cut across Y, then X).

       -h     Display some help.

       -V     Display program version and copyright.

EXAMPLE

       Create a cube-connected-cycle target architecture of dimension 4, and save it to file 'ccc4.tgt'.

           $ amk_ccc 4 ccc4.tgt

       Run gmap to compute a bisection, into two parts of respective weights 3 and 5, of  graph  'brol.grf'  and
       save the resulting mapping to file 'brol.map'. The dash '-' standard file name is used so that the target
       architecture description is read from the standard input, through the pipe.

           $ amk_p2 3 5 | gmap brol.grf - brol.map
