Parallel and Distributed Computation: Numerical Methods
This book was originally published by PrenticeHall in 1989, and republished by Athena Scientific in 1997 in
paperback form. It can be purchased from Athena Scientific or
it can be freely downloaded in scanned form, including the problem solution manual (730 pages,
about 55 Megs).
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.
