ABSTRACT A new augmented binary-tree multiprocessor architecture, called LAB-tree, is proposed. It consists of an n-level full/binary tree augmented with (2n-2) redundant links. The short and regular redundant links improve several properties of the full/binary tree, such as increased tolerance, reduced traffic congestion and efficient routing of messages. It is shown that there exist at least two node-disjoint paths between every pair of nodes in the LAB-tree. In fact, all nonfaulty nodes remain connected in the presence of one faulty node at each level of the tree. The LAB-tree supports simple shortest-path routing algorithms which distribute messages evenly over links. The LAB-tree can be constructed modularly in VLSI by interconnecting modules or smaller size.
