Book excerpt: Doctoral Thesis / Dissertation from the year 2013 in the subject Computer Science - General, grade: 90, University of Mosul (College of Computer Sciences And Mathematics), language: English, abstract: Now a day completed real-time systems are distributed. One of the working area of real-time scheduling is distributed scheduling. Task scheduling in distributed systems is dealt with two levels: on the level of each processor (local scheduling), and on the level of the allocation of tasks to processors (global scheduling). In this thesis, a distributed real-time system with fault tolerance has been designed and called Fault Tolerance Distributed Real Time System FTDRTS. The system consists of heterogeneous processors act as servers and clients connected together via LAN communication network. This system has two types of scheduling schemes: (1) global model scheduling, (2) independent model scheduling for scheduling tasks in real time distributed manner. The time utility function TUF has been developed and called the DTUF (Developed TUF) function. This function gives another dimension and used to priorities’ tasks, based on whether they are Urgent or Important, or both, or neither. A fault tolerance protocol called DRT-FTIP (Distributed Real Time – Fault Tolerance Integrity Protocol) has been developed. This protocol increases the integrity of the scheduling in distributed real time systems. The proposed Distributed Real-Time system with its scheduling algorithms and integrity protocol have been designed using the Java Remote Method Invocation (RMI) and use the Flight Reservation System as a case study. The simulation results of this proposed distributed realtime system using global scheduling algorithm gives Deadline Satisfaction Ratio (DSR) equal 95%. While Accrued Utility Ratio (AUR) equal 0.7286.

This book was released on 2018-08-09 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the previous work on load balancing and scheduling in distributed environments was concerned with homogeneous systems and homogeneous loads. Several of the results indicated that random policies are as effective as other more complex load allocation policies. The effects of heterogeneity on scheduling algorithms for hard real time systems is examined. A distributed scheduler specifically to handle heterogeneities in both nodes and node traffic is proposed. The performance of the algorithm is measured in terms of the percentage of jobs discarded. While a random task allocation is very sensitive to heterogeneities, the algorithm is shown to be robust to such non-uniformities in system components and load.

Book Synopsis Bounding the End-to-end Response Times of Tasks in a Distributed Real-time System Using the Direct Synchronization Protocol by : Jun Sun
Download or read book Bounding the End-to-end Response Times of Tasks in a Distributed Real-time System Using the Direct Synchronization Protocol written by Jun Sun and published by . 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."

Book Synopsis Task scheduling in hard real-time distributed systems on a synchronized single-channel broadcasting network by : Ying Hao
Download or read book Task scheduling in hard real-time distributed systems on a synchronized single-channel broadcasting network written by Ying Hao and published by . This book was released on 1991 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "This paper proposes a new scheme for global scheduling in a distributed system using a synchronized single-channel broadcasting network. Unlike existing solutions, our scheme does not require complete global state information to be collected for a node, which has an unschedulable aperiodic task, to find a node which can execute the task. The nodes are organized in our system in a logical ring fashion to synchronize the global scheduling process. To evaluate the performance of our scheme, two protocols are developed. Simulation results show the performance of the scheme close to an ideal distributed system, in which the centralized global scheduler takes care of aperiodic tasks without any communication and task migration overhead."
Book Synopsis Formal Methods Applied to Complex Systems by : Jean-Louis Boulanger
Download or read book Formal Methods Applied to Complex Systems written by Jean-Louis Boulanger and published by John Wiley & Sons. This book was released on 2014-07-22 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents real-world examples of formal techniques in an industrial context. It covers formal methods such as SCADE and/or the B Method, in various fields such as railways, aeronautics, and the automotive industry. The purpose of this book is to present a summary of experience on the use of “formal methods” (based on formal techniques such as proof, abstract interpretation and model-checking) in industrial examples of complex systems, based on the experience of people currently involved in the creation and assessment of safety critical system software. The involvement of people from within the industry allows the authors to avoid the usual confidentiality problems which can arise and thus enables them to supply new useful information (photos, architecture plans, real examples, etc.).
