HEURISTIC ALGORITHMS FOR DESIGNING SELF-REPAIRING PROTECTION TREES IN MESH NETWORKS


ABSTRACT:

Protection trees have been used in the past for restoring multicast and Uni-cast traffic in networks in various failure scenarios. In this paper we focus on shared self-repairing trees for page link protection in Uni-cast mesh networks. Shared protection trees have been proposed as a relatively simple approach that is easy to reconfigure and could provide sub-second restoration time ....etc

Mesh Algorithms in Parallel Processing

¢ Parallel processing is processing a task with several processing units, or many processors

¢ Most powerful computers contain two or more processing units that share among themselves the jobs submitted for processing

¢ Several operations are performed simultaneously, so the time taken by a computation can be reduced.

¢ A problem to be solved is broken into a no.of subproblems. These subproblems are now solved simultaneously, each on different processors. The results are then combi ....etc

A VLSI DESIGN CONCEPT FOR PARALLEL ITERATIVE ALGORITHMS
Abstract:
Modern VLSI manufacturing technology has kept shrinking down to the nanoscale level with a very fast trend.
Integration with the advanced nano-technology now makes it possible to realize advanced parallel iterative algorithms directly which was almost impossible 10 years ago. In this paper,
we want to discuss the influences of evolvin ....etc

There are a growing number of people who want to use remotely sensed data and GIS data. What is needed is a large-scale processing and storage system that provides high bandwidth at low cost.

Scalable computing clusters, ranging from a cluster of (homogeneous or heterogeneous) PCs or workstations, to SMPs, are rapidly becoming the standard platforms for high-performance and large-scale computing. To utilize the resources of a parallel computer, a problem had to be algorithmically expressed as comprising a set of concurrently executing sub-p ....etc

Abstract—In this paper, we show that the hexagonal mesh networks developed in the early 1990s are a special case of the EJ networks that have been considered more recently. Using a node addressing scheme based on the EJ number system, we give a shortest path routing algorithm for hexagonal mesh networks. We also extend the known efficient one-to-all broadcasting algorithm on hexagonal mesh networks to algorithms for one-to-one personalized broadcasting, all-to-all broadcasting, and all-to-all personalized broadcasting algorithms. Their time c ....etc

ABSTRACT

Over the past four decades the computer industry has experienced four generations of development. The first generation used Vacuum Tubes (1940 – 1950s) to discrete diodes to transistors (1950 – 1960s), to small and medium scale integrated circuits (1960 – 1970s) and to very large scale integrated devices (1970s and beyond). Increases in device speed and reliability and reduction in hardware cost and physical size have greatly enhanced computer performance ....etc

I. INTRODUCTION
Parallel Processing refers to the concept of speeding-up the execution of a program by dividing the program into multiple fragments that can execute simultaneously, each on its own processor. A program being executed across n processors might execute n times faster than it would using a single processor.
Traditionally, multiple processors were provided within a specially designed parallel computer; along these lines, Linux now supports SMP systems (often sold as servers) in which multiple processors ....etc
