چکیده

The binary hypercube, or n-cube, has been widely used as the interconnection network in parallel computers. However, the major drawback of the hypercube is the increase in the number of communication links for each node with the increase in the total number of nodes in the system. This paper introduces a new interconnection network for large-scale distributed memory multiprocessors called dual-cube. This network mitigates the problem of increasing number of links in the large-scale hypercube network while keeps most of the topological properties of the hypercube network. We investigate the topological properties of the dualcube, compare them with other hypercube-like networks, and establish the basic routing and broadcasting algorithms for dual-cubes.

Performance Analysis of a New Neural Network for Routing in Mesh Interconnection Networks

Routing is one of the basic parts of a message passing multiprocessor system. The routing procedure has a great impact on the efficiency of a system. Neural algorithms that are currently in use for computer networks require a large number of neurons. If a specific topology of a multiprocessor network is considered, the number of neurons can be reduced. In this paper a new recurrent neural ne...

Metacube – A New Interconnection Network for Large Scale Parallel Systems

The hypercube has been widely used as the interconnection network for parallel computers. However, in hypercubes, the number of communication links for each node is a logarithmic function of the total number of nodes. Therefore, the hypercube is not a good candidate for an interconnection network for a very large parallel computer that might contain hundreds of thousands of nodes due to IC tech...

خواص متریک و ترکیبیاتی مکعب‌های فیبوناتچی و لوکاس

An n-dimensional hypercube, Q_n, is a graph in which vertices are binary strings of length n where two vertices are adjacent if they differ in exactly one coordinate. Hypercubes and their subgraphs have a lot of applications in different fields of science, specially in computer science. This is the reason why they have been investigated by many authors during the years. Some of their subgraphs ...

Fault-Tolerant Routing and Disjoint Paths in Dual-Cube: A New Interconnection Network

In this paper, we introduce a new interconnection network, the dual-cube, its topological properties, and the routing/broadcasting algorithms in the dual-cube. The advanced subjects such as fault-tolerant routing and constructing multiple disjoint paths in dual-cubes are also included in this paper. The binary hypercube, or r-cube, can connect 2r nodes. In contrast, a dual-cube with r links for...
