Book excerpt: Abstract: "Considerable research has produced a plethora of efficient methods of exploiting parallelism on dedicated machines. On typical real systems, however, some of the important assumptions that lead to efficiency on a dedicated machine either do not hold or cause other problems on a machine which is time or space shared. Foremost among these assumptions is that the number of processors available to a parallel job is constant throughout the execution of the job. Maintaining such consistency in a real multiprogramming system can lead to poor utilization of the machine. This thesis will address issues involving the efficient exploitation of parallelism in a multiprogramming environment including OS support for user level scheduling and dynamic granularity control. Implementation of some of these techniques in the nanoThreads thread library will be discussed, as well as other details of the implementation of nanoThreads."
Book Synopsis Toward Efficient Scheduling for Parallel Real-time Tasks on Multiprocessors by : Son Ngoc Dinh

Available in PDF, EPUB and Kindle. Book excerpt: Modern real-time applications are becoming more demanding computationally while their temporal requirements, dictated by the physical world, often remain unchanged. This coupled with the increasing prevalence of multiprocessors in real-time systems necessitates that highly computation-demanding real-time tasks need to be parallelized to exploit the parallelism offered by the underlying hardware, in order to satisfy their temporal constraints. Scheduling parallel real-time tasks, however, introduces a new layer of complexity due to the allowance for intra-task parallelism. This dissertation addresses the problem of scheduling parallel real-time tasks in which tasks may (or may not) access shared non-processor resources, such as in-memory buffers or data structures. Specifically, for independent tasks, we propose new scheduling algorithms and schedulability analyses for parallel tasks with these characteristics, under federated and global scheduling.Experimental results show that the proposed algorithms and analyses improve the previously introduced methods. For parallel tasks that may access shared non-processor resources, we present a blocking analysis for two different types of spinlocks; through evaluations, we make a recommendation for a preferable ordering of locks. We also study practical runtime parallel scheduler designs for soft real-time applications and present a design that is more suitable for soft real-time systems.

Available in PDF, EPUB and Kindle. Book excerpt: A new model for task scheduling that dramatically improves the efficiency of parallel systems Task scheduling for parallel systems can become a quagmire of heuristics, models, and methods that have been developed over the past decades. The author of this innovative text cuts through the confusion and complexity by presenting a consistent and comprehensive theoretical framework along with realistic parallel system models. These new models, based on an investigation of the concepts and principles underlying task scheduling, take into account heterogeneity, contention for communication resources, and the involvement of the processor in communications. For readers who may be new to task scheduling, the first chapters are essential. They serve as an excellent introduction to programming parallel systems, and they place task scheduling within the context of the program parallelization process. The author then reviews the basics of graph theory, discussing the major graph models used to represent parallel programs. Next, the author introduces his task scheduling framework. He carefully explains the theoretical background of this framework and provides several examples to enable readers to fully understand how it greatly simplifies and, at the same time, enhances the ability to schedule. The second half of the text examines both basic and advanced scheduling techniques, offering readers a thorough understanding of the principles underlying scheduling algorithms. The final two chapters address communication contention in scheduling and processor involvement in communications. Each chapter features exercises that help readers put their new skills into practice. An extensive bibliography leads to additional information for further research. Finally, the use of figures and examples helps readers better visualize and understand complex concepts and processes. Researchers and students in distributed and parallel computer systems will find that this text dramatically improves their ability to schedule tasks accurately and efficiently.

This book was released on 2010-03-14 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overview and Goals This book is dedicated to scheduling for parallel processing. Presenting a research ?eld as broad as this one poses considerable dif?culties. Scheduling for parallel computing is an interdisciplinary subject joining many ?elds of science and te- nology. Thus, to understand the scheduling problems and the methods of solving them it is necessary to know the limitations in related areas. Another dif?culty is that the subject of scheduling parallel computations is immense. Even simple search in bibliographical databases reveals thousands of publications on this topic. The - versity in understanding scheduling problems is so great that it seems impossible to juxtapose them in one scheduling taxonomy. Therefore, most of the papers on scheduling for parallel processing refer to one scheduling problem resulting from one way of perceiving the reality. Only a few publications attempt to arrange this ?eld of knowledge systematically. In this book we will follow two guidelines. One guideline is a distinction - tween scheduling models which comprise a set of scheduling problems solved by dedicated algorithms. Thus, the aim of this book is to present scheduling models for parallel processing, problems de?ned on the grounds of certain scheduling models, and algorithms solving the scheduling problems. Most of the scheduling problems are combinatorial in nature. Therefore, the second guideline is the methodology of computational complexity theory. Inthisbookwepresentfourexamplesofschedulingmodels.

Book Synopsis Task Scheduling for Multi-core and Parallel Architectures by : Quan Chen
Download or read book Task Scheduling for Multi-core and Parallel Architectures written by Quan Chen and published by Springer. This book was released on 2017-11-23 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents task-scheduling techniques for emerging complex parallel architectures including heterogeneous multi-core architectures, warehouse-scale datacenters, and distributed big data processing systems. The demand for high computational capacity has led to the growing popularity of multicore processors, which have become the mainstream in both the research and real-world settings. Yet to date, there is no book exploring the current task-scheduling techniques for the emerging complex parallel architectures. Addressing this gap, the book discusses state-of-the-art task-scheduling techniques that are optimized for different architectures, and which can be directly applied in real parallel systems. Further, the book provides an overview of the latest advances in task-scheduling policies in parallel architectures, and will help readers understand and overcome current and emerging issues in this field.

Download or read book An Infrastructure for Efficient Parallel Job Execution in Terascale Computing Environments written by International Business Machines Corporation. Research Division and published by . This book was released on 1998 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Recent Terascale computing environments, such as those in the Department of Energy Accelerated Strategic Computing Initiative, present a new challenge to job scheduling and execution systems. The traditional way to concurrently execute multiple jobs in such large machines is through space-sharing: each job is given dedicated use of a pool of processors. Previous work in this area has demonstrated the benefits of sharing the parallel machine's resources not only spatially but also temporally. Time-sharing creates virtual processors for the execution of jobs. The scheduling is typically performed cyclically and each time-slice of the cycle can be considered an independent virtual machine. When all tasks of a parallel job are scheduled to run on the same time-slice (same virtual machine), gang-scheduling is accomplished. Research has shown that gang-scheduling can greatly improve system utilization and job response time in large parallel systems. We are developing GangLL, a research prototype system for performing gang-scheduling on the ASCI Blue-Pacific machine, an IBM RS/6000 SP to be installed at Lawrence Livermore National Laboratory. This machine consists of several hundred nodes, interconnected by a high-speed communication switch. GangLL is organized as a centralized scheduler that performs global decision-making, and a local daemon in each node that controls job execution according to those decisions. The centralized scheduler builds an Ousterhout matrix that precisely defines the temporal and spatial allocation of tasks in the system. Once the matrix is built, it is distributed to each of the local daemons using a scalable hierarchical distributions scheme. A two-phase commit is used in the distribution scheme to guarantee that all local daemons have consistent information. The local daemons enforce the schedule dedicated by the Ousterhout matrix in their corresponding nodes. This requires suspending and resuming execution of tasks and multiplexing access to the communication switch. Large supercomputing centers tend to have their own job scheduling systems, to handle site specific conditions. Therefore, we are designing GangLL so that it can interact with an external site scheduler. The goal is to let the site scheduler control spatial allocation of jobs, if so desired, and to decide when jobs run. GangLL then performs the detailed temporal allocation and controls the actual execution of jobs. The site scheduler can control the fraction of a shared processor that a job receives through an execution factor parameter. To quantify the benefits of our gang-scheduling system to job execution in a large parallel system, we simulate the system with a realistic workload. We measure performance parameters under various degrees of time-sharing, characterized by the multiprogramming level. Our results show that higher multiprogramming levels lead to higher system utilization and lower job response times. We also report some results from the initial deployment of GangLL on a small multiprocessor system."
