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.

This book was released on 1971 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Processor-sharing models of time-shared computer systems are defined and some new results are presented. The major emphasis of this research is on the modeling and analysis of new models of time-shared computer systems and on the finding of some fundamental properties which apply to the average number of customers in the system and the average response time functions for a large class of time-shared computer systems. The family of selfish scheduling algorithms is defined and the Laplace transform of the response time functions are obtained. A family of scheduling algorithms whose performance ranges between that of the RR system and the FB system is constructed. A simple relationship between the time-dependent average number of customers in the system and the average response time functions for a large class of M/M/1 systems is formulated. Finally, some fundamental properties are established which apply to the average response time functions for all time-shared computer systems. (Author).

Book excerpt: Research Paper (postgraduate) 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. The processes will be having different CPU bursts and different priority levels allocated to them. The process with the least priority magnitude is always picked next. A process already allocated the processor can be preempted the CPU and allocation done to another process with higher priority when such a process arrives in the queue. SJF with non-preemptive operates in the normal procedure whereby the job with the least CPU burst in the waiting queue is always picked next for allocation of the CPU and the rest of the processes have to wait no matter their urgency. Based on the introduction above, it is essential to use the right CPU scheduling strategy to help us achieve

Download or read book An analysis of central processor scheduling in multiprogrammed computer systems digest edition written by Stanford University. Computer Science Department and published by . 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: The people of metropolitan cities use water, electricity, LPG like services as per their need and pay for that. The persons are able to avail these facilities with the available resources. Nowadays, the world is integrated with various servers connected through the internet having versatile service facilities that can be used to complete many tasks easily through web browsers. We don't need to have different capable servers for different tasks. In the present era almost everything is available over the internet. The user can easily search for the services available on the cloud, avails the required services through internet for the solution of particular problem, and pay for the availed services. When many servers with different services and capabilities are networked and made available for the users to access through internet with minimum resources. Cloud computing is a computing technology in which distributed servers are networked to allow usage of resources like hardware, software, storage, applications, computing power services, design, and development environments through web-based tools. Users can use these services using the pay-per-use model through the web browser without knowing the underlying architecture of the cloud. Cloud computing is a new internet-based computing technology that provides various services to the client's through efficient utilization of multiple resources distributed geographically. This mechanism results in economic and operational benefits to users and also to service providers. In this computing mechanism, scheduling usually plays a very important role. The goal of the scheduling principle is to reduce the cost by reducing the total computation time (i.e.makespan) of a task. To improve the efficiency of cloud services, a proper scheduling algorithm plays an important role. When a large number of users access the services of the cloud, then efficient scheduling of these services becomes a challenge. Therefore scheduling is an important and challenging problem in cloud computing. Overall, the purpose is to design a scheduling algorithm that makes efficient use of the available resources on cloud to perform computation, manages workload among the available resources, and improves the performance of the cloud.
