Book Synopsis Fault-Tolerant Message-Passing Distributed Systems by : Michel Raynal
Download or read book Fault-Tolerant Message-Passing Distributed Systems written by Michel Raynal and published by Springer. This book was released on 2018-09-08 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the most important fault-tolerant distributed programming abstractions and their associated distributed algorithms, in particular in terms of reliable communication and agreement, which lie at the heart of nearly all distributed applications. These programming abstractions, distributed objects or services, allow software designers and programmers to cope with asynchrony and the most important types of failures such as process crashes, message losses, and malicious behaviors of computing entities, widely known under the term "Byzantine fault-tolerance". The author introduces these notions in an incremental manner, starting from a clear specification, followed by algorithms which are first described intuitively and then proved correct. The book also presents impossibility results in classic distributed computing models, along with strategies, mainly failure detectors and randomization, that allow us to enrich these models. In this sense, the book constitutes an introduction to the science of distributed computing, with applications in all domains of distributed systems, such as cloud computing and blockchains. Each chapter comes with exercises and bibliographic notes to help the reader approach, understand, and master the fascinating field of fault-tolerant distributed computing.

Download or read book Distributed Computing Through Combinatorial Topology written by Maurice Herlihy and published by Newnes. This book was released on 2013-11-30 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distributed Computing Through Combinatorial Topology describes techniques for analyzing distributed algorithms based on award winning combinatorial topology research. The authors present a solid theoretical foundation relevant to many real systems reliant on parallelism with unpredictable delays, such as multicore microprocessors, wireless networks, distributed systems, and Internet protocols. Today, a new student or researcher must assemble a collection of scattered conference publications, which are typically terse and commonly use different notations and terminologies. This book provides a self-contained explanation of the mathematics to readers with computer science backgrounds, as well as explaining computer science concepts to readers with backgrounds in applied mathematics. The first section presents mathematical notions and models, including message passing and shared-memory systems, failures, and timing models. The next section presents core concepts in two chapters each: first, proving a simple result that lends itself to examples and pictures that will build up readers' intuition; then generalizing the concept to prove a more sophisticated result. The overall result weaves together and develops the basic concepts of the field, presenting them in a gradual and intuitively appealing way. The book's final section discusses advanced topics typically found in a graduate-level course for those who wish to explore further. - Named a 2013 Notable Computer Book for Computing Methodologies by Computing Reviews - Gathers knowledge otherwise spread across research and conference papers using consistent notations and a standard approach to facilitate understanding - Presents unique insights applicable to multiple computing fields, including multicore microprocessors, wireless networks, distributed systems, and Internet protocols - Synthesizes and distills material into a simple, unified presentation with examples, illustrations, and exercises

Book Synopsis Quantum Computing: Physics, Blockchains, And Deep Learning Smart Networks by : Melanie Swan
Download or read book Quantum Computing: Physics, Blockchains, And Deep Learning Smart Networks written by Melanie Swan and published by World Scientific. This book was released on 2020-03-20 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum information and contemporary smart network domains are so large and complex as to be beyond the reach of current research approaches. Hence, new theories are needed for their understanding and control. Physics is implicated as smart networks are physical systems comprised of particle-many items interacting and reaching criticality and emergence across volumes of macroscopic and microscopic states. Methods are integrated from statistical physics, information theory, and computer science. Statistical neural field theory and the AdS/CFT correspondence are employed to derive a smart network field theory (SNFT) and a smart network quantum field theory (SNQFT) for the orchestration of smart network systems. Specifically, a smart network field theory (conventional or quantum) is a field theory for the organization of particle-many systems from a characterization, control, criticality, and novelty emergence perspective.This book provides insight as to how quantum information science as a paradigm shift in computing may influence other high-impact digital transformation technologies, such as blockchain and machine learning. Smart networks refer to the idea that the internet is no longer simply a communications network, but rather a computing platform. The trajectory is that of communications networks becoming computing networks (with self-executing code), and perhaps ultimately quantum computing networks. Smart network technologies are conceived as autonomous self-operating computing networks. This includes blockchain economies, deep learning neural networks, autonomous supply chains, self-piloting driving fleets, unmanned aerial vehicles, industrial robotics cloudminds, real-time bidding for advertising, high-frequency trading networks, smart city IoT sensors, and the quantum internet.
Book Synopsis Concurrent Crash-Prone Shared Memory Systems by : Raynal Michel
Download or read book Concurrent Crash-Prone Shared Memory Systems written by Raynal Michel and published by Springer Nature. This book was released on 2022-05-31 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theory is what remains true when technology is changing. So, it is important to know and master the basic concepts and the theoretical tools that underlie the design of the systems we are using today and the systems we will use tomorrow. This means that, given a computing model, we need to know what can be done and what cannot be done in that model. Considering systems built on top of an asynchronous read/write shared memory prone to process crashes, this monograph presents and develops the fundamental notions that are universal constructions, consensus numbers, distributed recursivity, power of the BG simulation, and what can be done when one has to cope with process anonymity and/or memory anonymity. Numerous distributed algorithms are presented, the aim of which is being to help the reader better understand the power and the subtleties of the notions that are presented. In addition, the reader can appreciate the simplicity and beauty of some of these algorithms.

Book excerpt: Not your usual post-apocalyptic story. In the near future, a chemical attack destroys the ozone layer, forcing survivors into the sprawling five-tier underground city of Orion. For Kaz Winters, the move marks deep change. Within a week, her father, a lab technician, vanishes. Soon after, she and her mother are relocated to the city's lowest level. Life at the bottom is brutal in a city where the poor are barely tolerated. But it's not just inequality Kaz must face. A deadly radiation-borne disease called the Scourge spreads, claiming victims indiscriminately. When her mother falls ill, a desperate Kaz must steal the medicine to save her. Her luck changes when she stumbles upon her father's journal, which hints at a potential cure for the Scourge. However, the key to it lies beyond the tightly controlled world of Orion. The choice for Kaz is brutally simple. Do nothing or venture to the surface—a place no one is meant to survive. Get your copy of Dawn Impact today! Get ready for a gripping, post-apocalyptic adventure packed with rich characters and a tense, dystopian atmosphere. Perfect for fans of Kyla Stone, Franklin Horton, T.L. Payne, and Grace Hamilton.
Book Synopsis Be sparse! Be dense! Be robust! by : Sorge, Manuel
Download or read book Be sparse! Be dense! Be robust! written by Sorge, Manuel and published by Universitätsverlag der TU Berlin. This book was released on 2017-05-31 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis we study the computational complexity of five NP-hard graph problems. It is widely accepted that, in general, NP-hard problems cannot be solved efficiently, that is, in polynomial time, due to many unsuccessful attempts to prove the contrary. Hence, we aim to identify properties of the inputs other than their length, that make the problem tractable or intractable. We measure these properties via parameters, mappings that assign to each input a nonnegative integer. For a given parameter k, we then attempt to design fixed-parameter algorithms, algorithms that on input q have running time upper bounded by f(k(q)) * |q|^c , where f is a preferably slowly growing function, |q| is the length of q, and c is a constant, preferably small. In each of the graph problems treated in this thesis, our input represents the setting in which we shall find a solution graph. In addition, the solution graphs shall have a certain property specific to our five graph problems. This property comes in three flavors. First, we look for a graph that shall be sparse! That is, it shall contain few edges. Second, we look for a graph that shall be dense! That is, it shall contain many edges. Third, we look for a graph that shall be robust! That is, it shall remain a good solution, even when it suffers several small modifications. Be sparse! In this part of the thesis, we analyze two similar problems. The input for both of them is a hypergraph H , which consists of a vertex set V and a family E of subsets of V , called hyperedges. The task is to find a support for H , a graph G such that for each hyperedge W in E we have that G[W ] is connected. Motivated by applications in network design, we study SUBSET INTERCONNECTION DESIGN, where we additionally get an integer f , and the support shall contain at most |V| - f + 1 edges. We show that SUBSET INTERCONNECTION DESIGN admits a fixed-parameter algorithm with respect to the number of hyperedges in the input hypergraph, and a fixed-parameter algorithm with respect to f + d , where d is the size of a largest hyperedge. Motivated by an application in hypergraph visualization, we study r-OUTERPLANAR SUPPORT where the support for H shall be r -outerplanar, that is, admit a edge-crossing free embedding in the plane with at most r layers. We show that r-OUTER-PLANAR SUPPORT admits a fixed-parameter algorithm with respect to m + r , where m is the number of hyperedges in the input hypergraph H. Be dense! In this part of the thesis, we study two problems motivated by community detection in social networks. Herein, the input is a graph G and an integer k. We look for a subgraph G' of G containing (exactly) k vertices which adheres to one of two mathematically precise definitions of being dense. In mu-CLIQUE, 0 < mu <= 1, the sought k-vertex subgraph G' should contain at least mu time k choose 2 edges. We study the complexity of mu-CLIQUE with respect to three parameters of the input graph G: the maximum vertex degree delta, h-index h, and degeneracy d. We have delta >= h >= d in every graph and h as well as d assume small values in graphs derived from social networks. For delta and for h, respectively, we obtain fixed-parameter algorithms for mu-CLIQUE and we show that for d + k a fixed-parameter algorithm is unlikely to exist. We prove the positive algorithmic results via developing a general framework for optimizing objective functions over k-vertex subgraphs. In HIGHLY CONNECTED SUBGRAPH we look for a k-vertex subgraph G' in which each vertex shall have degree at least floor(k/2)+1. We analyze a part of the so-called parameter ecology for HIGHLY CONNECTED SUBGRAPH, that is, we navigate the space of possible parameters in a quest to find a reasonable trade-off between small parameter values in practice and efficient running time guarantees. The highlights are that no 2^o(n) * n^c -time algorithms are possible for n-vertex input graphs unless the Exponential Time Hypothesis fails; that there is a O(4^g * n^2)-time algorithm for the number g of edges outgoing from the solution G; and we derive a 2^(O(sqrt(a)log(a)) + a^2nm-time algorithm for the number a of edges not in the solution. Be robust! In this part of the thesis, we study the VECTOR CONNECTIVITY problem, where we are given a graph G, a vertex labeling ell from V(G) to {1, . . . , d }, and an integer k. We are to find a vertex subset S of V(G) of size at most k such that each vertex v in V (G)\S has ell(v) vertex-disjoint paths from v to S in G. Such a set S is useful when placing servers in a network to satisfy robustness-of-service demands. We prove that VECTOR CONNECTIVITY admits a randomized fixed-parameter algorithm with respect to k, that it does not allow a polynomial kernelization with respect to k + d but that, if d is treated as a constant, then it allows a vertex-linear kernelization with respect to k. In dieser Dissertation untersuchen wir die Berechnungskomplexität von fünf NP-schweren Graphproblemen. Es wird weithin angenommen, dass NP-schwere Probleme im Allgemeinen nicht effizient gelöst werden können, das heißt, dass sie keine Polynomialzeitalgorithmen erlauben. Diese Annahme basiert auf vielen bisher nicht erfolgreichen Versuchen das Gegenteil zu beweisen. Aus diesem Grund versuchen wir Eigenschaften der Eingabe herauszuarbeiten, die das betrachtete Problem handhabbar oder unhandhabbar machen. Solche Eigenschaften messen wir mittels Parametern, das heißt, Abbildungen, die jeder möglichen Eingabe eine natürliche Zahl zuordnen. Für einen gegebenen Parameter k versuchen wir dann Fixed-Parameter Algorithmen zu entwerfen, also Algorithmen, die auf Eingabe q eine obere Laufzeitschranke von f(k(q)) * |q|^c erlauben, wobei f eine, vorzugsweise schwach wachsende, Funktion ist, |q| die Länge der Eingabe, und c eine Konstante, vorzugsweise klein. In den Graphproblemen, die wir in dieser Dissertation studieren, repräsentiert unsere Eingabe eine Situation in der wir einen Lösungsgraph finden sollen. Zusätzlich sollen die Lösungsgraphen bestimmte problemspezifische Eigenschaften haben. Wir betrachten drei Varianten dieser Eigenschaften: Zunächst suchen wir einen Graphen, der sparse sein soll. Das heißt, dass er wenige Kanten enthalten soll. Dann suchen wir einen Graphen, der dense sein soll. Das heißt, dass er viele Kanten enthalten soll. Zuletzt suchen wir einen Graphen, der robust sein soll. Das heißt, dass er eine gute Lösung bleiben soll, selbst wenn er einige kleine Modifikationen durchmacht. Be sparse! In diesem Teil der Arbeit analysieren wir zwei ähnliche Probleme. In beiden ist die Eingabe ein Hypergraph H, bestehend aus einer Knotenmenge V und einer Familie E von Teilmengen von V, genannt Hyperkanten. Die Aufgabe ist einen Support für H zu finden, einen Graphen G, sodass für jede Hyperkante W in E der induzierte Teilgraph G[W] verbunden ist. Motiviert durch Anwendungen im Netzwerkdesign betrachten wir SUBSET INTERCONNECTION DESIGN, worin wir eine natürliche Zahl f als zusätzliche Eingabe bekommen, und der Support höchstens |V| - f + 1 Kanten enthalten soll. Wir zeigen, dass SUBSET INTERCONNECTION DESIGN einen Fixed-Parameter Algorithmus in Hinsicht auf die Zahl der Hyperkanten im Eingabegraph erlaubt, und einen Fixed-Parameter Algorithmus in Hinsicht auf f + d, wobei d die Größe einer größten Hyperkante ist. Motiviert durch eine Anwendung in der Hypergraphvisualisierung studieren wir r-OUTERPLANAR SUPPORT, worin der Support für H r-outerplanar sein soll, das heißt, er soll eine kantenkreuzungsfreie Einbettung in die Ebene erlauben mit höchstens r Schichten. Wir zeigen, dass r-OUTERPLANAR SUPPORT einen Fixed-Parameter Algorithmus in Hinsicht auf m + r zulässt, wobei m die Anzahl der Hyperkanten im Eingabehypergraphen H ist. Be dense! In diesem Teil der Arbeit studieren wir zwei Probleme, die durch Community Detection in sozialen Netzwerken motiviert sind. Dabei ist die Eingabe ein Graph G und eine natürliche Zahl k. Wir suchen einen Teilgraphen G' von G, der (genau) k Knoten enthält und dabei eine von zwei mathematisch präzisen Definitionen davon, dense zu sein, aufweist. In mu-CLIQUE, 0 < mu <= 1, soll der gesuchte Teilgraph G' mindestens mu mal k über 2 Kanten enthalten. Wir studieren die Berechnungskomplexität von mu-CLIQUE in Hinsicht auf drei Parameter des Eingabegraphen G: dem maximalen Knotengrad delta, dem h-Index h, und der Degeneracy d. Es gilt delta >= h >= d für jeden Graphen und h als auch d nehmen kleine Werte in Graphen an, die aus sozialen Netzwerken abgeleitet sind. Für delta und h erhalten wir Fixed-Parameter Algorithmen für mu-CLIQUE und wir zeigen, dass für d + k wahrscheinlich kein Fixed-Parameter Algorithmus existiert. Unsere positiven algorithmischen Resultate erhalten wir durch Entwickeln eines allgemeinen Frameworks zum Optimieren von Zielfunktionen über k-Knoten-Teilgraphen. In HIGHLY CONNECTED SUBGRAPH soll in dem gesuchten k-Knoten-Teilgraphen G' jeder Knoten Knotengrad mindestens floor(k/2) + 1 haben. Wir analysieren einen Teil der sogenannten Parameter Ecology für HIGHLY CONNECTED SUBGRAPH. Das heißt, wir navigieren im Raum der möglichen Parameter auf der Suche nach einem vernünftigen Trade-off zwischen kleinen Parameterwerten in der Praxis und effizienten oberen Laufzeitschranken. Die Highlights hier sind, dass es keine Algorithmen mit 2^o(n) * poly(n)-Laufzeit für HIGHLY CONNECTED SUBGRAPH gibt, es sei denn die Exponential Time Hypothesis stimmt nicht; die Entwicklung eines Algorithmus mit O(4^y * n^2 )-Laufzeit, wobei y die Anzahl der Kanten ist, die aus dem Lösungsgraphen G' herausgehen; und die Entwicklung eines Algorithmus mit 2^O(sqrt(a) log(a)) + O(a^2nm)-Laufzeit, wobei a die Anzahl der Kanten ist, die nicht in G' enthalten sind.

This book was released on 2020-02-05 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive analysis of Brooks-Iyengar Distributed Sensing Algorithm, which brings together the power of Byzantine Agreement and sensor fusion in building a fault-tolerant distributed sensor network. The authors analyze its long-term impacts, advances, and future prospects. The book starts by discussing the Brooks-Iyengar algorithm, which has made significant impact since its initial publication in 1996. The authors show how the technique has been applied in many domains such as software reliability, distributed systems and OS development, etc. The book exemplifies how the algorithm has enhanced new real-time features by adding fault-tolerant capabilities for many applications. The authors posit that the Brooks-Iyengar Algorithm will to continue to be used where fault-tolerant solutions are needed in redundancy system scenarios. This book celebrates S.S. Iyengar's accomplishments that led to his 2019 Institute of Electrical and Electronics Engineers' (IEEE) Cybermatics Congress "Test of Time Award" for his work on creating Brooks-Iyengar Algorithm and its impact in advancing modern computing.

Book Synopsis Distributed Computing by : David Peleg
Download or read book Distributed Computing written by David Peleg and published by SIAM. This book was released on 2000-01-01 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents the locality-sensitive approach to distributed network algorithms-the utilization of locality to simplify control structures and algorithms and reduce their costs. The author begins with an introductory exposition of distributed network algorithms focusing on topics that illustrate the role of locality in distributed algorithmic techniques. He then introduces locality-preserving network representations and describes sequential and distributed techniques for their construction. Finally, the applicability of the locality-sensitive approach is demonstrated through several applications. Gives a thorough exposition of network spanners and other locality-preserving network representations such as sparse covers and partitions. The book is useful for computer scientists interested in distributed computing, electrical engineers interested in network architectures and protocols, and for discrete mathematicians and graph theorists.
