It features a systematic approach to the latest design techniques, providing analysis and implementation details for each parallel algorithm described in the book. Its fast, its easy and fewer course materials help minimise costs for your students. Like in the analysis of ordinary, sequential, algorithms, one is typically interested in asymptotic bounds on the resource consumption mainly time spent computing, but the analysis is performed in the presence of multiple processor units that cooperate to perform computations. These algorithms are well suited to todays computers, which basically perform operations in a sequential fashion. Introduction to parallel algorithms and architectures.

A parallel algorithm is an algorithm that can execute several instructions simultaneously on different processing devices and then combine all the individual outputs to produce the final result. Kumar and others published introduction to parallel computing. Basic communication operations latex sources and figures 5. Algorithms in which several operations may be executed simultaneously are referred to as parallel algorithms.
Similarly, many computer science researchers have used a socalled. Parallel searches using, sbut 2 concurrent binary searches, log and log goal. Written by an authority in the field, this book provides an introduction to the design and analysis of parallel algorithms. A parallel algorithm for a parallel computer can be defined as set of processes that may be executed simultaneously and may communicate with each other in order to solve a given problem. The emphasis is on the application of the pram parallel random access machine model of parallel computation, with all its variants, to algorithm analysis. The term processmay be defined as a part of a program that can be run on a processor.
