Parallel and Distributed Computation: Numerical Methods

Dimitri P. Bertsekas and John N. Tsitsiklis

This book was originally published by Prentice-Hall in 1989, and republished by Athena Scientific in 1997 in paperback form, and in 2015 in hardcover. The paperback version will be discontinued sometime in mid-2015. Both the paperback and hardcover versions can be purchased from Athena Scientific. The book can be freely downloaded in scanned form (735 pages, about 55 Megs). The problem solution manual may also be freely downloaded.

The book is a comprehensive and theoretically sound treatment of parallel and distributed numerical methods. It focuses on algorithms that are naturally suited for massive parallelization, and it explores the fundamental convergence, rate of convergence, communication, and synchronization issues associated with such algorithms.
