Opis

Understanding distributed computing is not an easy task. This is due to the many facets of uncertainty one has to cope with and master in order to produce correct distributed software. Considering the uncertainty created by asynchrony and process crash failures in the context of message-passing systems, the book focuses on the main abstractions that one has to understand and master in order to be able to produce software with guaranteed properties. These fundamental abstractions are communication abstractions that allow the processes to communicate consistently (namely the register abstraction and the reliable broadcast abstraction), and the consensus agreement abstractions that allows them to cooperate despite failures. As they give a precise meaning to the words "communicate" and "agree" despite asynchrony and failures, these abstractions allow distributed programs to be designed with properties that can be stated and proved. Impossibility results are associated with these abstractions. Hence, in order to circumvent these impossibilities, the book relies on the failure detector approach, and, consequently, that approach to fault-tolerance is central to the book.

Michel Raynal is a professor of computer science at the University of Rennes, France. His main research interests are the basic principles of distributed computing systems. Michel Raynal is the author of numerous papers on distributed algorithms and a world leading re[1]searcher in the domain of distributed computing. He has chaired the program committee of the major conferences on the topic, such as the IEEE Int’l Conference on Distributed Computing Systems (ICDCS), the Symposium on Distributed Computing (DISC), the Int’l Colloquium on Structural Information and Communication Complexity (SIROCCO), and the Int’l Conference on Principles of Distributed Systems (OPODIS). He has also served on the program committees of many international conferences, and he is the recipient of several “Best Paper” awards. Michel Raynal has been invited by many universities all over the world to give lectures on distributed computing.
