Book Synopsis Multiprocessor Scheduling for Real-Time Systems by : Sanjoy Baruah
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.

Book Synopsis Issues in Multiprogrammed Multiprocessor Scheduling by : Scott T. Leutenegger
Download or read book Issues in Multiprogrammed Multiprocessor Scheduling written by Scott T. Leutenegger and published by . This book was released on 1990 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Minimizing spin-waiting is achieved by coscheduling processes within a job, or by using a thread management package that avoids preemption of processes that hold spinlocks.) We also find that allocation of processing power among competing jobs is a more important characteristic of a scheduling policy than preemption frequency for a wide range of preemption overhead values. Our studies are done by simulating abstract models of the system and the workloads."
Book Synopsis Energy-aware Scheduling on Multiprocessor Platforms by : Dawei Li
Download or read book Energy-aware Scheduling on Multiprocessor Platforms written by Dawei Li and published by Springer Science & Business Media. This book was released on 2012-10-19 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiprocessor platforms play important roles in modern computing systems, and appear in various applications, ranging from energy-limited hand-held devices to large data centers. As the performance requirements increase, energy-consumption in these systems also increases significantly. Dynamic Voltage and Frequency Scaling (DVFS), which allows processors to dynamically adjust the supply voltage and the clock frequency to operate on different power/energy levels, is considered an effective way to achieve the goal of energy-saving. This book surveys existing works that have been on energy-aware task scheduling on DVFS multiprocessor platforms. Energy-aware scheduling problems are intrinsically optimization problems, the formulations of which greatly depend on the platform and task models under consideration. Thus, Energy-aware Scheduling on Multiprocessor Platforms covers current research on this topic and classifies existing works according to two key standards, namely, homogeneity/heterogeneity of multiprocessor platforms and the task types considered. Under this classification, other sub-issues are also included, such as, slack reclamation, fixed/dynamic priority scheduling, partition-based/global scheduling, and application-specific power consumption, etc.

Download or read book Self-scheduling, Data Synchronization and Program Transformation for Multiprocessor Systems written by Peiyi Tang and published by . This book was released on 1989 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The limitation of vector supercomputing and of device speed has led to the development of multiprocessor supercomputers. Although large tightly-coupled shared-memory multiprocessor systems have become feasible, such systems cannot be considered successful, unless their numerous processors can coordinate with each other efficiently for a wide range of applications. Advanced software techniques and their supports from system architectures are keys to the success of modern multiprocessor supercomputers. This dissertation first concentrates on two important software issues for large multiprocessor systems: processor scheduling and data synchronization. Self-scheduling, an efficient dynamic heuristic scheduling, is a practical solution to the scheduling problem of multiprocessor systems. We propose several self-scheduling schemes which can be used by a compiler to generate self-scheduling object codes for parallel programs. Since busy-waiting is used to enforce cross-iteration data dependences, deadlocks in self-scheduling are possible. We identify the conditions that allow deadlock-free self-scheduling for different self-scheduling models and propose the use of an appropriate scheduling order for allocating processors to prevent deadlocks. Self-scheduling order also has significant impact on the performance of parallel loops with cross-iteration data dependences. We propose the shortest-delay self-scheduling (SDSS) order based on Doacross delays determined by cross-iteration data dependences. We show by simulation that SDSS can offer near-optimal performance in most cases. A compile-time program transformation for SDSS is also presented. Data synchronization is necessary to enforce cross-iteration data data dependences. We propose a set of data-level synchronization instructions to support data synchronization. Compiler algorithms for generating these data-level synchronization instructions for different types of subscript functions are presented. The last part of the dissertation addresses an architecture issue of large multiprocessor systems: "hot-spot" contention. We suggest the use of software combining to distribute "hot-spot" addressings. A number of software combining algorithms for different access patterns, such as barrier synchronization, fetch-and-add type of operations and semaphore P/V operations, are presented.

Book Synopsis Scheduler-Conscious Synchronization by : University of Rochester. Dept. of Computer Science
Download or read book Scheduler-Conscious Synchronization written by University of Rochester. Dept. of Computer Science and published by . This book was released on 1994 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Efficient synchronization is important for achieving good performance in parallel programs, especially on large-scale multiprocessors. Most synchronization algorithms have been designed to run on a dedicated machine, with one application process per processor, and can suffer serious performance degradation in the presence of multiprogramming. Problems arise when running processes block or, worse, busy-wait for action on the part of a process that the scheduler has chosen not to run. In this paper we describe and evaluate a set of scheduler- conscious synchronization algorithms that perform well in the presence of multiprogramming while maintaining good performance on dedicated machines. We consider both large and small machines, with a particular focus on scalability, and examine mutual-exclusion locks, reader-writer locks, and barriers. The algorithms we study fall into two classes: those that heuristically determine appropriate behavior and those that use scheduler information to guide their behavior. We show that while in some cases either method is sufficient, in general sharing information across the kernel-user interface both eases the design of synchronization algorithms and improves their performance."
Book Synopsis Multiprocessor Systems-on-Chips by : Ahmed Jerraya
Download or read book Multiprocessor Systems-on-Chips written by Ahmed Jerraya and published by Morgan Kaufmann. This book was released on 2005 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern system-on-chip (SoC) design shows a clear trend toward integration of multiple processor cores on a single chip. Designing a multiprocessor system-on-chip (MPSOC) requires an understanding of the various design styles and techniques used in the multiprocessor. Understanding the application area of the MPSOC is also critical to making proper tradeoffs and design decisions. Multiprocessor Systems-on-Chips covers both design techniques and applications for MPSOCs. Design topics include multiprocessor architectures, processors, operating systems, compilers, methodologies, and synthesis algorithms, and application areas covered include telecommunications and multimedia. The majority of the chapters were collected from presentations made at the International Workshop on Application-Specific Multi-Processor SoC held over the past two years. The workshop assembled internationally recognized speakers on the range of topics relevant to MPSOCs. After having refined their material at the workshop, the speakers are now writing chapters and the editors are fashioning them into a unified book by making connections between chapters and developing common terminology. *Examines several different architectures and the constraints imposed on them *Discusses scheduling, real-time operating systems, and compilers *Analyzes design trade-off and decisions in telecommunications and multimedia applications
