Available in PDF, EPUB and Kindle. Book excerpt: In a distributed real-time system or communication network, tasks may need to be executed on more than one processor. For time-critical tasks, the timing constraints are typically given as end-to-end release times and deadlines. This thesis describes algorithms to schedule a class of systems where all the tasks execute on different processors in turn in the same order. This end-to-end scheduling problem is known as the flow-shop problem. We present several cases where the problem is tractable and evaluate two heuristic algorithms for the NP-hard general case. We generalize the traditional flow-shop model in two directions. First, we present two algorithms for scheduling flow shops where tasks can be serviced more than once by some processors. Second, we describe a technique to schedule flow shops that consist of periodic tasks and to analyze their schedulability. We generalize this technique and describe how it can be used to schedule distributed systems that can not be modeled by flow shops. We then describe how to combine local or global resource access protocols and end-to-end scheduling. Finally, we show that by using end-to-end scheduling we can simplify resource access protocols and thus increase the utilization of resources.

This book was released on 2012-12-06 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many real-time systems rely on static scheduling algorithms. This includes cyclic scheduling, rate monotonic scheduling and fixed schedules created by off-line scheduling techniques such as dynamic programming, heuristic search, and simulated annealing. However, for many real-time systems, static scheduling algorithms are quite restrictive and inflexible. For example, highly automated agile manufacturing, command, control and communications, and distributed real-time multimedia applications all operate over long lifetimes and in highly non-deterministic environments. Dynamic real-time scheduling algorithms are more appropriate for these systems and are used in such systems. Many of these algorithms are based on earliest deadline first (EDF) policies. There exists a wealth of literature on EDF-based scheduling with many extensions to deal with sophisticated issues such as precedence constraints, resource requirements, system overload, multi-processors, and distributed systems. Deadline Scheduling for Real-Time Systems: EDF and Related Algorithms aims at collecting a significant body of knowledge on EDF scheduling for real-time systems, but it does not try to be all-inclusive (the literature is too extensive). The book primarily presents the algorithms and associated analysis, but guidelines, rules, and implementation considerations are also discussed, especially for the more complicated situations where mathematical analysis is difficult. In general, it is very difficult to codify and taxonomize scheduling knowledge because there are many performance metrics, task characteristics, and system configurations. Also, adding to the complexity is the fact that a variety of algorithms have been designed for different combinations of these considerations. In spite of the recent advances there are still gaps in the solution space and there is a need to integrate the available solutions. For example, a list of issues to consider includes: preemptive versus non-preemptive tasks, uni-processors versus multi-processors, using EDF at dispatch time versus EDF-based planning, precedence constraints among tasks, resource constraints, periodic versus aperiodic versus sporadic tasks, scheduling during overload, fault tolerance requirements, and providing guarantees and levels of guarantees (meeting quality of service requirements). Deadline Scheduling for Real-Time Systems: EDF and Related Algorithms should be of interest to researchers, real-time system designers, and instructors and students, either as a focussed course on deadline-based scheduling for real-time systems, or, more likely, as part of a more general course on real-time computing. The book serves as an invaluable reference in this fast-moving field.

This book was released on 2012-12-06 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a selection of papers that focus on the state-of the-art in real-time scheduling and resource management. Preliminary versions of these papers were presented at a workshop on the foundations of real-time computing sponsored by the Office of Naval Research in October, 1990 in Washington, D.C. A companion volume by the title Foundations of Real-Time Computing: Fonnal Specifications and Methods complements this book by addressing many of the most advanced approaches currently being investigated in the arena of formal specification and verification of real-time systems. Together, these two texts provide a comprehensive snapshot of current insights into the process of designing and building real-time computing systems on a scientific basis. Many of the papers in this book take care to define the notion of real-time system precisely, because it is often easy to misunderstand what is meant by that term. Different communities of researchers variously use the term real-time to refer to either very fast computing, or immediate on-line data acquisition, or deadline-driven computing. This text is concerned with the very difficult problems of scheduling tasks and resource management in computer systems whose performance is inextricably fused with the achievement of deadlines. Such systems have been enabled for a rapidly increasing set of diverse end-uses by the unremitting advances in computing power per constant-dollar cost and per constant-unit-volume of space. End-use applications of deadline-driven real-time computers span a spectrum that includes transportation systems, robotics and manufacturing, aerospace and defense, industrial process control, and telecommunications.

This book was released on 1996 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In a distributed real-time system, a task may consist of a chain of subtasks which execute on different processors. In order to guarantee that all timing constraints are met in such a system, it is imperative to be able to determine the end-to-end response time for each task. This report focuses on distributed systems where tasks are periodic and scheduled according to fixed priority scheduling algorithms. Moreover, if a subtask has predecessors, every instance of the subtask is released as soon as the corresponding instance of the immediate predecessor subtask completes. This report describes an algorithm that can be used to find upper bounds on the end-to-end response times of tasks in such a distributed real-time system."

This book was released on 2000-06 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distributed systems have grown in popularity due to the rapid increase in networking of personal computers. A mixture of computers consisting of different architectures can be more powerful, reliable, and scalable than a single supercomputer. The problem of optimally scheduling jobs on a cluster of heterogeneous machines to minimize the time at which the last machine finishes is NP-complete. Nonetheless, the choice of a heuristic algorithm greatly affects the speed of solution. This work evaluates a greedy algorithm, an A* algorithm, and a simulated annealing algorithm applied to the heterogeneous scheduling problem with deadline and dependency constraints. Tradeoffs of speed and schedule quality were noted between the algorithms. The greedy algorithm produced results quicker than the A* and simulated annealing algorithms, but with a lower schedule quality. Because of these offsetting performance criteria, an analysis was conducted to determine which algorithms should be used for which input cases.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "This paper describes heuristic algorithms for scheduling preemptive, imprecise, composite tasks with input error and end- to-end timing constraints. Each composite task consists of a chain of component tasks, where each component task is made up of a mandatory part and an optional part. Whenever a component task uses imprecise input, the mandatory and optional parts of the component task may be extended in order to compensate for input error. We use a two-level scheduler. At the high level, the scheduler schedules the composite tasks preemptively on one processor, according to an existing algorithm for scheduling simple imprecise tasks. The result is the total amount of time budgeted to each composite task in order for all composite tasks to meet their end-to-end deadlines. The low-level scheduler then distributes the time budgeted for each composite task across its component tasks so as to minimize the output error of each composite task."

Available in PDF, EPUB and Kindle. Book excerpt: Welcome to IWQOS'97 in New York City! Over the past several years, there has been a considerable amount of research within the field of Quality of Service (QOS). Much of that work has taken place within the context of QOS support for distributed multimedia systems, operating systems, transport subsystems, networks, devices and formal languages. The objective of the Fifth International Workshop on Quality of Service (IWQOS) is to bring together researchers, developers and practitioners working in all facets of QOS research. While many workshops and conferences offer technical sessions on the topic QOS, none other than IWQOS, provide a single-track workshop dedicated to QOS research. The theme of IWQOS'97 is building QOS into distributed systems. Implicit in that theme is the notion that the QOS community should now focus on discussing results from actual implementations of their work. As QOS research moves from theory to practice, we are interested in gauging the impact of ideas discussed at previous workshops on development of actual systems. While we are interested in experimental results, IWQOS remains a forum for fresh and innovative ideas emerging in the field. As a result of this, authors were solicited to provide experimental research (long) papers and more speculative position (short) statements for consideration. We think we have a great invited and technical program lined up for you this year. The program reflects the Program Committees desire to hear about experiment results, controversial QOS subjects and retrospectives on where we are and where we are going.
