Weak System Models for Distributed Agreement Problems
Broschiertes Buch
This book investigates theoretical aspects of system models for agreement problems in fault-tolerant distributed computing. A distributed system is a collection of processes that communicate with each other by sending messages over a network. Achieving agreement among these processes despite failures is a difficult but important problem. Care must be taken when choosing a system model as a too restrictive model will be applicable to very few systems, whereas too relaxed assumptions might severely reduce the set of problems that can be solved. Part I of this book provides an introduction to the context of this work, discusses related literature and describes the basic system assumptions. Part II introduces the Asynchronous Bounded-Cycle model which is entirely time-free but nevertheless sufficient to solve fault-tolerant consensus despite Byzantine faults. Part III presents an in-depth treatment of algorithms and models for solving the k-set agreement problem which requires processes to agree on at most k distinct values.…mehr

?Robinson is an author with amazing empathy, a snare-trap ear for dialogue, and a clear eye for the telling detail.??Michael Connelly One of the world's greatest suspense writers returns with the 27th novel featuring the legendary detective Alan Banks in the mystery series Stephen King calls ?the best now on the market.? When property developer Connor Clive Blaydon is found dead, Detective Superintendent Alan Banks and his Yorkshire team dive into the investigation. As luck would have it, someone had installed a cache of spy-cams all around his luxurious home. The team hope that they'll find answers?and the culprit?among the video recordings. Instead of discovering Connor's murderer, however, the grainy and blurred footage reveals another crime: a brutal rape. If they can discover the woman's identity, it could lead to more than justice for the victim; it could change everything the police think they know about Connor and why anyone would want him dead. Meanwhile, tensions are rising between Banks and his friend, Zelda. A super recognizer?able to recognize faces significantly better than most people?Zelda is determined to bring the men who abused her to justice. But stirring up the murky waters of the past will put her in far greater danger than ever before, and Banks worries that he won't be able to stop her from plunging too deep before it's too late.…mehr
