Download or read book Expanding Symmetric Multiprocessor Capability Through Gang Scheduling written by and published by . This book was released on 1998 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Symmetric Multiprocessor (SMP) systems normally provide both space- sharing and time-sharing to insure high system utilization and good responsiveness. However the prevailing lack of concurrent scheduling for parallel programs precludes SMP use in addressing many large-scale problems. Tightly synchronized communications are impractical and normal time-sharing reduces the benefit of cache memory. Evidence gathered at Lawrence Livermore National Laboratory (LLNL) indicates that gang scheduling can increase the capability of SMP systems and parallel program performance without adverse impact upon system utilization or responsiveness.

Download or read book Multiprocessor Scheduling for Real Time Systems written by Sanjoy Baruah and published by Springer. This book was released on 2015-01-02 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of both theoretical and pragmatic aspects of resource-allocation and scheduling in multiprocessor and multicore hard-real-time systems. The authors derive new, abstract models of real-time tasks that capture accurately the salient features of real application systems that are to be implemented on multiprocessor platforms, and identify rules for mapping application systems onto the most appropriate models. New run-time multiprocessor scheduling algorithms are presented, which are demonstrably better than those currently used, both in terms of run-time efficiency and tractability of off-line analysis. Readers will benefit from a new design and analysis framework for multiprocessor real-time systems, which will translate into a significantly enhanced ability to provide formally verified, safety-critical real-time systems at a significantly lower cost.

Download or read book New Backfilling Algorithm for Multiprocessor Scheduling with Gang Scheduling written by R. Siyambalapitiya and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, we propose an efficient algorithm for the multiprocessor job scheduling problem. From a given list of jobs, jobs are queued according to the decreasing order of their durations. Depending upon the job duration, jobs are divided into multiple threads for processing. Multithread jobs are processed based on the concept of 'gang scheduling.' To minimize the idle time of the processors, backfilling approach is incorporated into the algorithm.
Download or read book Performance of a Few Gang Scheduling Algorithms for Multiprocessor Scheduling written by R. Siyambalapitiya and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, the performance of several approximation algorithms for multiprocessor scheduling is considered. Multiprocessor scheduling is an NP-hard problem which means that it may not be possible to design exact algorithms to solve this problem to optimality. Therefore, designing of approximation algorithms to solve this problem appears to be the only option available. The algorithms considered are designed incorporating the gang scheduling approach. An attempt is made to obtain solutions close to optimal using these algorithms. The study shows that these algorithms can be used to solve even large-scale problems occurring in practice.

Download or read book Slot Scheduling written by and published by . This book was released on 2005 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents slot scheduling, a approach to general-purpose CPU scheduling for multiprocessor systems. The chief virtues of slot scheduling are versatility (the ability to support a broad range of classes of schedulers) and intelligibility (allowing system designers to easily reason about interactions among different kinds of schedulers). In particular, slot scheduling is well-suited for meeting the needs of both real-time and gang-scheduled applications. These characteristics distinguish slot scheduling from existing scheduler proposals which tend to suffer from overspecialization and complexity. Slot scheduling achieves its goals by employing an explicit ``bulletin board'' representation of CPU allocation that decentralizes the task of scheduling from the kernel and permits scheduling logic to be carried out by applications themselves. We show that this approach is both feasible and efficient.

This book was released on 2010-10 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parallel processing has seen incredible growth with increasingly complex scientific & engg applications coming to their realm.Task scheduling, a key issue for its success,& design of efficient algorithms play a crucial role in it.Due to NP-completeness of the problem research efforts are mainly focussed at heuristic-based approaches to generate near-optimal schedules within reasonable time & resource constraints.Most of the heuristics, however, ignore practical aspect and/or compromise too much on complexity or performance.This monograph provides an in-depth insight into these issues.An overview of state-of-the-art scheduling, reflecting changing paradigms, is also provided.In addition, for scheduling DAG structured applications,3 efficient algorithms are presented & analyzed for homogeneous, heterogeneous & mixed-parallel computing environments.Selective-duplication heuristic is introduced and its usefulness in dealing with IPC overhead is shown in comparison to list, clustering and duplication-based heuristics.An A-cube performance model is suggested to comprehensively study behavior of algorithm, application & architecture in heterogeneous environment.
Download or read book Fault Tolerant Real Time Scheduling for Multiprocessor Systems written by Rakesh K Bansal and published by LAP Lambert Academic Publishing. This book was released on 2011-01 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Owing to advances in VLSI and other related technologies, real-time systems have come to an age where their presence is being felt in almost every facet of human life.There is a steady rising trend in the fraction of all processors, manufactured worldwide, that find their way to real-time applications. Most of these time and mission critical applications demand reliable processing environment to guarantee error free execution and completion within the respective time deadlines. Scheduling algorithms can provide low-cost solutions to fault-tolerance and graceful performance degradation by exploiting tradeoffs between space or time redundancy, timing accuracy, and quality of service. The intricacies of Primary- Backup fault-tolerance approach that works fine for independent task scheduling are explored for DAG structured applications through examples. This work contributes toward understanding and analyzing fault-tolerance issue for precedence-constrained real-time applications, on homogeneous and heterogeneous multiprocessing platforms, and developing a new 100% 1-fault-tolerant algorithm in this much desirable and critical research area.

It addresses most of the issues that need to be resolved in the design and development of continuously evolving, rich, diversified modern operating systems and describes successful implementation approaches in the form of abstract models and algorithms. This book is primarily intended for use in undergraduate courses in any discipline and also for a substantial portion of postgraduate courses that include the subject of operating systems. It can also be used for self-study.
