However, compiled architecture files are read much more efficiently, as they are
directly loaded into memory without further processing. Since the compilation
time of a target architecture graph evolves as the square of its number of
vertices, precompiling with
acpl
can save some time when many mappings
are to be performed onto the same large target architecture.

Description
The
amk
* programs make target graphs. Each of them is devoted to a
specific topology, for which it builds target graphs of any dimension.
These programs are an alternate way between algorithmically-coded built-in
target architectures and decompositions computed by mapping with
amk grf
.
Like built-in target architectures, their decompositions are algorithmically
computed, and like
amk grf
, their output is a decomposition-defined target
architecture file. These programs allow the definition and testing of new
algorithmically-coded target architectures without coding them in the core of
the mapper.
Program
amk ccc
outputs the target architecture file of a Cube-Connected-
Cycles graph of dimension
dim
.
Vertex (
l, m
) of CCC(
dim
), with
0
≤
l < dim
and 0
≤
m <
2
dim
, is linked to vertices ((
l
−
1) mod
dim, m
),
((
l
+ 1) mod
dim, m
), and (
l, m
⊕
2
l
), and is labeled
l
×
2
dim
+
m
.
⊕
denotes
the bitwise exclusive-or binary operator, and
a
mod
b
the integer remainder
of the euclidian division of
a
by
b
.
Program
amk fft2
outputs the target architecture file of a binary Fast-
Fourier-Transform graph of dimension
dim
.
Vertex (
l, m
) of FFT(
dim
),
with 0
≤
l
≤
dim
and 0
≤
m <
2
dim
, is linked to vertices (
l
−
1
, m
),
(
l

mod 2
l
−
1
), (
l

l

, m
⊕
2
l
), if they exist, and is labeled
l
