Ebook: Algorithms and Architectures for Parallel Processing: 8th International Conference, ICA3PP 2008, Cyprus, June 9-11, 2008 Proceedings

This book constitutes the refereed proceedings of the 8th International Conference on Algorithms and Architectures for Parallel Processing, ICA3PP 2008, held in Agia Napa, Cyprus, in June 2008.

The 31 revised full papers presented together with 1 keynote talk and 1 tutorial were carefully reviewed and selected from 88 submissions. The papers are organized in topical sections on scheduling and load balancing, interconnection networks, parallel algorithms, distributed systems, parallelization tools, grid computing, and software systems.

Abstract. As the ever-growing Internet applications in the emerging e-societyare centered in sharing of various types of digital contents, content delivery onthe Internet as a hot topic has been attracting most attentions. Web caching is animportant technology for improving the efficiency of content delivery. As anemerging technology en-route caching computes locations among caches on accesspaths to store copies of an object such that specified objectives (such assatisfying future access demands to the object) are achieved. In this talk, I willfirst give an overview on recent developments in efficient content delivery. Iwill then introduce our recent work in tackling this problem by applying thetechnique of en-route caching, and present efficient solutions to the problem insystems containing single server and multiple servers respectively. While theproblem is NP-hard in the general case, our solutions apply dynamic programmingtechnique and run in polynomial-time in the worst case for both unconstrainedand constrained cases in the network topologies of trees (for broadcastdelivery) and linear arrays (for point-to-point delivery) respectively. They areshown theoretically either optimal or convergent to optimal. Finally, I willshow some possible extensions of our solutions to other system settings.
