Synopsis
Excerpt from On the Shadow Cpu Approximation for Modelling Priority Scheduling in Computer Systems
We shall use a model proposed by [sevc, 77] that contains very little of the complexity of an actual system but still reflects the intrinsic difficulty of analytically approaching priority scheduling. flue queuing network is a closed cyclic uetggtg_of two servers: a cpu and an i/o server. There are just two cystomer classes, with class 1 having pre-emptive priority over class -the cpu, while all scheduling is fcfs at the i/o. That L(jiept-rlazl processor will be devoted to class 1 whenever a class 1_job; is, availahle for service. Within each class jobs are served irpyfcejsiggdetfl'og-ixhe average service times at the i/o are the same (x3) ffxyboghggiasse§~hut the average cpu service times (bemeen i/o -t-=for the two classes (xi for class i, i Jobs always teturn to the cpu after being served at the i/o. We assume, for simplicity, that the service time distribution of the i/o is exponential (of rate u3 X51) and the cpu service for class 1 is exponential (rate 1 Xfl). For class 2 the same holds, when the cpu service time distribution is conditional to the event of absence of class 1 jobs from the cpu.

Print on DemandSeller: Forgotten Books, London, United Kingdom
Seller rating 5 out of 5 stars
Paperback. Condition: New. Print on Demand. This book delves into a problem in computer science - that of performance evaluation in computer systems - and proposes a sound methodology to address it. The author presents queuing network models as cost-effective tools for performance evaluation. The insights presented in this book enhance our understanding of priority scheduling models and their limitations, using shadow CPU-based techniques. The author provides an optimal approximation to the priority model, which is pessimistic for the performance of the high priority class and admits a product form solution. The book also includes a suboptimal model that is computationally efficient and outperforms the original shadow CPU technique. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Seller Inventory # 9781332173198_0
