BUTTERFLY NETWORK Butterfly network is a network with 2q nodes and q + 1 columns as an unfolded q-cube in order to facilitate the discussion‚ visualization‚ and analysis of hypercube routing algorithms. However‚ a butterfly network can be viewed as a parallel processing architecture in its own right. A butterfly architecture (Fig. A‚ left) has p = 2 q(q + 1) processors of maximum degree d = 4‚ a diameter of 2q = ∪(log p)‚ and a bisection width of ( – 1)2 q+1 + 0(2 q) = ∪(p/log p). A wrapped
