Hypertree: A Multiprocessor Interconnection Topology
Goodman, Sequin · IEEE Transactions on Computers · 1981
A new interconnection topology for incrementally expansible multicomputer systems is described, which combines the easy expansibility of tree structures with the compactness of the n-dimensional hypercube. The addition of n-cube links to the binary tree structure provides direct paths between nodes which have frequent data exchange in algorithms such as sorting and fast Fourier transforms (FFT's). The derivation of a family of such Hypertree structures is outlined, and the basic properties such as average path length, uniformity of the distribution of message traffic, and routing algorithms are analyzed.
