This note describes an algorithm for broadcasting a message on the \(n\)-dimensional hypercube in optimal time ( \(n\) time units) and optimal communication ( \(2^{n}-1\) messages) in the presence of up to \(n-2\) arbitrary node or edge faults, assuming the set of faults is known to all nodes of the
computing. Therefore, it is necessary to compute important primitive functions even in the presence of faults. The hypercube network is quite robust [2,20]; in fact, at least n faults are needed to disconnect Q n into two components. The symmetry and robustness of hypercube can be exploited to compu
We consider broadcasting a message from one node of a tree to all other nodes. In the presence of up to k link failures the tree becomes disconnected, and only nodes in the connected component C containing the source can be informed. The maximum ratio between the time used by a broadcasting scheme B
We discuss the fault tolerance of an information disseminating scheme in a processor network called a binary jumping network. The following results are shown. Let \(N\) be the number of processors in the network. When \(N\) is a power of \(2, \log _{2} N+f+1\) rounds suffice for broadcasting in the
