Embedding of tree networks into hypercubes

Angela Y Wu
1985 Journal of Parallel and Distributed Computing  
The hypercube is a good host graph for the embedding of networks of processors because of its low degree and low diameter.  ...  Graphs such as trees and arrays can be embedded into a hypercube with small dilation and expansion costs, but there are classes of graphs which can be embedded into a hypercube only with large expansion  ...  relations are preserved.  ...

Embeddings into Hyper Petersen Networks: Yet Another Hypercube-Like Interconnection Topology

Sajal K. Das, Sabine Öhring, Amit K. Banerjee

Fault-Tolerant Optimal Broadcast Algorithm For The Hypercube Topology

Lokendra Singh Umrao, Ravi Shankar Singh
2015 Zenodo  
This paper presents an optimal broadcast algorithm for the hypercube networks. The main focus of the paper is the effectiveness of the algorithm in the presence of many node faults.  ...  For the optimal solution, our algorithm builds with spanning tree connecting the all nodes of the networks, through which messages are propagated from source node to remaining nodes.  ...  Any process in hypercube topology can be the root. We present a new way of construction of optimal spanning tree and show its strong relation with the binomial tree.  ...

HyperCast: A Protocol for Maintaining Multicast Group Members in a Logical Hypercube Topology [chapter]

Jörg Liebeherr, Tyler K. Beam
1999 Lecture Notes in Computer Science  
We use measurement experiments of an implementation of the protocol on a networked computer cluster to quantitatively assess the performance of the protocol for multicast group sizes up to 1024 members  ...  Recently, we proposed the use of a control topology, which organizes multicast group members in a logical n-dimensional hypercube, and transmits all control information along the edges of the hypercube  ...  For example, we plan to use the tree embedding algorithm from Section 3 to provide ARQ error control.  ...

Balanced spanning trees in complete and incomplete star graphs

Tzung-Shi Chen, Yu-Chee Tseng, Jang-Ping Sheu
1996 IEEE Transactions on Parallel and Distributed Systems  
In this paper, we show how to construct in a complete star graph an asymptotically balanced spanning tree, and in an incomplete star graph a near-balanced spanning tree.  ...  Efficiently solving the personalized broadcast problem in an interconnection network typically relies on finding an appropriate spanning tree in the network.  ...  The star graph has been considered as an attractive alternative to the widely accepted hypercube as the network architecture for parallel processing.  ...

Fully normal algorithms for incomplete hypercubes

V.K. Prabhala, N.A. Sherwani
