This book was released on 1972 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simple finite source model is used to gain insight into the effect of central processor scheduling in multiprogrammed computer systems. CPU utilization is chosen as the measure of performance and this decision is discussed. A relation between CPU utilization and flow time is developed. It is shown that the shortest-remaining-processing-time discipline maximizes both CPU utilization and I/O utilization for the queueing model M/G/1/n. An exact analysis of processor utilization using shortest-remaining-processing-time scheduling for systems with two jobs is given and it is observed that the processor utilization is independent of the form of the processing time distribution. The effect of the CPU processing time distribution on performance is discussed. The results are used to compare several scheduling disciplines of practical interest. An approximate expression for CPU utilization using shortest-remaining-processing-time scheduling in systems with N jobs is given. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: Research Paper from the year 2011 in the subject Computer Science - Commercial Information Technology, grade: A, Massachusetts Institute of Technology, language: English, abstract: CPU scheduling is a technique used by computer operating systems to manage the usage of the computer's central processing unit. In a multi-programming environment whereby several processes are running on the same processor, it is essential to use scheduling criteria to avoid collisions in the computer's operations. This will help users in a given information technology oriented firm to share server spaces and resources like printers and file storage spaces. In the multi-tasking environment, a program called CPU scheduler selects one of the ready processes and allocates the processor to it. There are a number of occasions when a new process can or must be chosen to run: When a running process block and changes its state to 'Blocked', When a timer for a running process expires, When a waiting process unblocks and changes its state to 'Ready', and When a running process terminates and changes its state to 'Exit' (Wikipedia, 2013). Different types of scheduling programs referred to as algorithms can be employed in CPU scheduling instances. Among the most popular scheduling algorithms is Shortest Job First (SJF). SJF gives the processor to the process with the shortest next time allocation known as the burst. If there are processes with similar CPU bursts in the event queue, the scheduler uses First Come First Served algorithm which allocates the first process to arrive in the queue to the processor regardless of its burst time. It operates under the assumption that the length of the next CPU burst of each of the processes in ready queue is known (CPU scheduling, 2013). The SJF algorithm can be used in both pre-emptive and non-preemptive methods. The algorithm can be preemptive or not. Shortest Job First with preemption uses priority measure to determine the next process to be given the CPU.

This book was released on 1996 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Gang scheduling is a resource management scheme for parallel and distributed systems that combines time-sharing with space- sharing to ensure short response times for interactive tasks and high overall system throughput. In this paper, we present and analyze a queueing theoretic model for a general gang scheduling scheme that forms the basis of a multiprogramming environment currently being developed for IBM's SP2 parallel system and for clusters of workstations. Our model and analysis can be used to tune our scheduler in order to maximize its performance on each hardware platform."

Research Division and published by . This book was released on 1995 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In this paper, we analyze three general classes of space-sharing scheduling policies under a workload representative of large- scale scientific computing. These policies differ in the manner in which processors are partitioned among the jobs as well as the way in which jobs are prioritized for execution on the partitions. We propose new adaptive and dynamic policies that differ from previously proposed policies in that, in their scheduling decisions, they can make use of user-supplied information about the resource requirements of submitted jobs. We examine the performance characteristics of these policies from both the system and user perspectives. Our results indicate that existing static schemes do not perform well under varying workloads, and that to provide good performance for such workloads the system scheduling policy must distinguish between jobs with large differences in execution times. We show that a judiciously parameterized dynamic space-sharing policy can outperform adaptive policies from both the system and user perspectives. Moreover, obtaining good performance under adaptive policies requires a priori knowledge of the job mix submitted to the system. Dynamic policies do not require prior information about the workload and are therefore preferable in unpredictable environments."
