operating system assignments

Virginia International University School of Computer Information Systems CMP 641 Operating Systems Fall 2016 (HW Assignment 2) Review the attached paper by Anchal Thakur and Ravinder Thakur (2015) titled “Multicore Efficient Scheduling for Operating System to Avoid Congestion In Client-Server Architecture” issued by IEEE International Conference on Green Computing and Internet of Things (ICGCIoT). To support multitasking operating system in the domain of multicore processor scheduling and synchronization, the authors noted that their proposed application is applicable to the application level, which can also be extended to the web level and mobile based applications (Thakur & Thakur, 2015). Abrite Inc., a software development company, has received a contract to design a start-of-the-art operating system to be implemented on real time systems to accelerate scientific, analytics, engineering, and enterprise applications. Additionally, the applications are expected to achieve high performance by using more cores, hardware threads, and higher memory to meeting the growing demands for convenience, performance, and efficiency. Based on your reading in the paper, answer the following questions and provide reasons to support your recommendation: a) Summarize the OS scheduling policies (e.g. FCFS, SRT, SPN, RR, etc.) and recommend the most reliable and efficient policy for this new operating system. b) Which of the process scheduling algorithms is most likely to lead to starvation? c) A scheduling algorithm assigns priority proportional to the waiting time of a process. Every process starts with the lowest priority. The scheduler re-evaluates the process priorities every T time units and decides the next process to schedule. Discuss this concept with respect to the authors’ position. You should limit your responses to ONLY ONE two pagea in length, well-organized and well-written to conform to VIU Guide to Writing and APA Requirements. Note: ALL submissions should be converted to PDF file format. Failure to confirm to this requirement may earn you zero credit. In support of your response, cite at least four (4) credible outside sources, as well as the textbook, for a total of at least five (5) sources. Place these in a reference page formatted in accordance with APA style. This reference page does not count toward the total page requirement. Ensure that you match in-text citation with the list of references in the reference page. 1 Note the following carefully: 1. ALL submissions should be converted to PDF file format. Failure to confirm to this requirement may earn you zero credits. 2. Please keep in mind that you are honor-bond not to communicate the question/answer with others. Just copying words from resources will not give you full credits. 3. For full credit, use your own words. 4. Ensure that you revisit and review the Academic Dishonesty Policy and Procedures from within the course room or the VIU website. 5. This assignment MUST be turned in before the deadlines to receive credits. Missing classes does NOT excuse you from meeting the deadlines. No exception please! References Thakur, A. & Thakur, R. (2015). Multicore efficient scheduling for operating system to avoid congestion in client-server architecture. International Conference on Green Computing and Internet of Things (ICGCIoT)/IEEE. 2
