Algorithms for Mutual Exclusion

by Michel Raynal

The problem of mutual exclusion - or of defining fundamental operations so that it is possible to resolve conflicts resulting from several concurrent processes sharing the resources of a computer system - has emerged over the last 20 years as a prime example of the difficulties associated with parallel or distributed programming. The implementation of a mutual exclusion mechanism, therefore, is a very real phenomenon that faces every designer of operating systems as well as applications programmers who use services provided by computer systems built around several processing units, or linked by a network.This book presents a remarkable survey of a vast field of concrete and highly complex research on algorithms for parallel or distributed control. Since parallelism makes it difficult to understand the behavior or to analyze the properties of algorithms that can solve these problems, all of the algorithms have been rewritten in a single language and restructured so that they are easy to understand and compare. The book systematically stresses the principles guiding their design, provides arguments to prove their validity and gives quantitative data allowing their assessment. Preface.
