- A 2-D torus and a binary hypercube are both k-ary n-cubes.
- In the torus, n=2, in the binary hypercube, k=2.
-
- Nonetheless, that difference in radix/dimension has such
- implications that saying they are basically the same doesn't
- really help a lot :-).

- Check out the performance analysis by Bill Dally in IEEE TC
- June 91 (I think). "Performance Analysis of k-ary n-cubes)
- (I have a subsequent, more general, analysis if you are interested).
