This book constitutes the refereed proceedings of the 7th International Conference on Algorithms and Architectures for Parallel Processing, ICA3PP 2007, held in Hangzhou, China in June 2007.

The 39 revised full papers presented together with 1 keynote talk and 3 invited lectures were carefully reviewed and selected from 176 submissions. Focussing on two broad areas of parallel and distributed computing, i.e., architectures, algorithms and networks, and systems and applications, the papers are organized in topical sections on parallel algorithms, parallel architecture, grid computing, peer-to-peer technologies, and advanced network technologies.
