Book excerpt: Distributed deadlock is a state where there exists among some processes running on different computers a cyclic wait to acquire some resources such that no process can proceed. Since a deadlock is a state that persists unless it is solved by some method, and the number and size of deadlocks increase substantially as the concurrency level or number of sites in a distributed system grows, we need an efficient approach to solve this problem. Distributed deadlock resolution consists of choosing a victim, aborting and restarting it. There has been no detailed study of resolution, despite the fact that deadlock detection does not complete its task without resolution. The performance analysis of different resolution strategies that have been proposed and new approaches for distributed deadlock resolution are the subject of this study. Different heuristic strategies (rules) to choose victims to break deadlocks are discussed and the direct and indirect goals that the rules were hypothesized to achieve are described. Various simulation runs (experiments) were conducted to analyze in depth the performance of the rules. The system throughput and the overhead of running the rules are evaluated and the effectiveness of each rule in achieving its goals are compared. The assessment of each rule under different system conditions is used to evaluate the possibility of incorporating more than one rule in deadlock resolution. This leads to the suggestion for use of a first-principles expert system to monitor and diagnose distributed systems, including the resolution of problems such as deadlocks. The rule base of such an expert system would include rules to choose the optimum victim to resolve a distributed deadlock.

This book was released on 2016 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Deadlock is a common phenomenon in software applications, yet it is ignored by most operating systems. Although the occurrence of a deadlocks in systems is not frequent, in some cases, the effects are drastic when deadlock occurs. The ongoing trend in processor technology indicates that future systems will have hundreds and thousands of cores. Due to this imminent trend in hardware development, the problem of deadlock has gained renewed attention in research. Deadlock handling techniques that are developed for earlier processors and distributed systems might not work well with multicore systems, due to their architectural differences. Hence, to maximize the utility of multicore systems, new programs have to be carefully designed and tested before they can be adopted for practical use. Many approaches have been developed to handle deadlock in multicore systems, but very little attention has been paid to comparing the performance of those approaches with respect to different performance parameters. To fulfil the above mentioned shortfalls, we need a flexible simulation testbed to study deadlock handling algorithms and to observe their performance differences in multicore systems. The development of such a framework is the main goal of this thesis. In the framework, we implemented a general a scenario, scenario for the Dining Philosopher’s problem and scenario for the Banker’s algorithm. In addition to these scenarios, we demonstrate the flexibility, soundness, and use of the proposed framework by simulating two different deadlock handling strategies – deadlock avoidance (the Banker’s algorithm) and deadlock detection (Dreadlocks). The deadlock detection is followed by deadlock recovery to resolve the detected deadlock. We also present result analysis for the different set of experiments performed on the implemented strategies. The proposed simulation testbed to study deadlocks in multicore systems is developed using Java."--Leaf i.

Download or read book Deadlock Resolution in Computer Integrated Systems written by MengChu Zhou and published by CRC Press. This book was released on 2018-10-08 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex computer-integrated systems offer enormous benefits across a wide array of applications, including automated production, transportation, concurrent software, and computer operating systems, computer networks, distributed database systems, and many other automated systems. Yet, as these systems become more complex, automated, distributed, and computing-intensive, the opportunity for deadlock issues rises exponentially. Deadlock modeling, detection, avoidance, and recovery are critical to improving system performance. Deadlock Resolution in Computer-Integrated Systems is the first text to summarize and comprehensively treat this issue in a systematic manner. Consisting of contributions from prominent researchers in the field, this book addresses deadlock-free models and scheduling, detection and recovery methods, the formulation of dynamic control policies, and comparison and industrial benchmark studies that evaluate various approaches. The editors lay the foundation for exploring deadlock issues with a typical example of an automated manufacturing process, illustrating three primary modeling methods (digraphs, Petri nets, and automata) and comparing their respective advantages and disadvantages. Providing all of the important models and resolution approaches, this book is the complete guide for electrical and control engineers and manufacturing, intelligent, and network systems designers to prevent and manage deadlock issues in their systems.

Available in PDF, EPUB and Kindle. Book excerpt: With the advent of distributed computing systems, the problem of deadlock, which has been essentially solved for centralized computing systems, has reappeared. Existing centralized deadlock detection techniques are either too expensive or they do not work correctly in distributed computing systems. Although several algorithms have been developed specifically for distributed systems, the majority of them have also been shown to be inefficient or incorrect. Additionally, although fault-tolerance is usually listed as an advantage of distributed computing systems, little has been done to analyze the fault tolerance of these algorithms. This thesis analyzes four published deadlock detection algorithms for distributed computing systems with respect ot their performance in the presence of certain faults. A new deadlock detection algorithm is then proposed whose efficiency and fault tolerance are adjustable. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Welcometotheproceedingsofthe2ndInternationalSymposiumonParalleland Distributed Processing and Applications (ISPA2004) which was held in Hong Kong, China, 13–15 December, 2004. With the advance of computer networks and hardware technology, parallel and distributed processing has become a key technology which plays an imp- tant part in determining future research and development activities in many academic and industrial branches. It provides a means to solve computati- ally intensive problems by improving processing speed. It is also the only - ableapproachtobuildinghighlyreliableandinherentlydistributedapplications. ISPA2004 provided a forum for scientists and engineers in academia and ind- try to exchange and discuss their experiences, new ideas, research results, and applications about all aspects of parallel and distributed computing. There was a very large number of paper submissions (361) from 26 countries and regions, including not only Asia and the Paci?c, but also Europe and North America. All submissions were reviewed by at least three program or technical committee members or external reviewers. It was extremely di?cult to select the presentations for the conference because there were so many excellent and interesting submissions. In order to allocate as many papers as possible and keep the high quality of the conference, we ?nally decided to accept 78 regular papers and 38 short papers for oral technical presentations. We believe that all of these papers and topics not only provide novel ideas, new results, work in progress and state-of-the-art techniques in this ?eld, but also stimulate the future research activities in the area of parallel and distributed computing with applications.
