This book was released on 2012-12-06 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advent of the world-wide web and web-based applications have dramatically changed the nature of computer applications. Computer system design, in the light of these changes, involves understanding these modem workloads, identifying bottlenecks during their execution, and appropriately tailoring microprocessors, memory systems, and the overall system to minimize bottlenecks. This book contains ten chapters dealing with several contemporary programming paradigms including Java, web server and database workloads. The first two chapters concentrate on Java. While Barisone et al.'s characterization in Chapter 1 deals with instruction set usage of Java applications, Kim et al.'s analysis in Chapter 2 focuses on memory referencing behavior of Java workloads. Several applications including the SPECjvm98 suite are studied using interpreter and Just-In-Time (TIT) compilers. Barisone et al.'s work includes an analytical model to compute the utilization of various functional units. Kim et al. present information on locality, live-range of objects, object lifetime distribution, etc. Studying database workloads has been a challenge to research groups, due to the difficulty in accessing standard benchmarks. Configuring hardware and software for database benchmarks such as those from the Transactions Processing Council (TPC) requires extensive effort. In Chapter 3, Keeton and Patterson present a simplified workload (microbenchmark) that approximates the characteristics of complex standardized benchmarks.

Available in PDF, EPUB and Kindle. Book excerpt: The report presents a comprehensive set of hierarchically organized modular analytical models developed for the performance evaluation of multiprogrammed virtual-memory time-shared computer systems using demand paging. The hierarchy of models contains a user behavior model, a secondary memory model, a program behavior model, a processor model, and a total system model. This thesis is particularly concerned with the last three models. The program behavior model developed in this thesis permits one to estimate the frequency of paging expected on a given processing system. The processor model enables one to evaluate the throughput of a given multi-processor multi-memory processing system under multiprogramming. Finally, the total system model allows us to derive the response time distribution of an entire computer system under study. The report includes two PL/I programs. (Author).

Download or read book Workload Characterization of Computer Systems and Computer Networks written by Giuseppe Serazzi and published by North Holland. This book was released on 1986 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally recognized that the characteristics of workload processing requests are among those parameters that critically affect the behaviour of a computer system. Therefore, the quantitative description of the processing requests, i.e. the workload characterization, is of fundamental importance in all performance evaluation problems, and is indispensable in the design of useful workload models. Now, for the first time, all problems related to workload characterization and modeling have been gathered together and analyzed in one volume. This book presents both the basic principles and the state-of-the-art in workload characterization of computer systems and computer networks, with special emphasis on experimental aspects. The methodologies and techniques currently used to characterize workloads for performance evaluation studies (tuning, design, selection, and capacity planning) are all adequately described.

This book was released on 2012-12-06 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formal study of program behavior has become an essential ingredient in guiding the design of new computer architectures. Accurate characterization of applications leads to efficient design of high performing architectures. Quantitative and analytical characterization of workloads is important to understand and exploit the interesting features of workloads. This book includes ten chapters on various aspects of workload characterizati on. File caching characteristics of the industry-standard web-serving benchmark SPECweb99 are presented by Keller et al. in Chapter 1, while value locality of SPECJVM98 benchmarks are characterized by Rychlik et al. in Chapter 2. SPECJVM98 benchmarks are visited again in Chapter 3, where Tao et al. study the operating system activity in Java programs. In Chapter 4, KleinOsowski et al. describe how the SPEC2000 CPU benchmark suite may be adapted for computer architecture research and present the small, representative input data sets they created to reduce simulation time without compromising on accuracy. Their research has been recognized by the Standard Performance Evaluation Corporation (SPEC) and is listed on the official SPEC website, http://www. spec. org/osg/cpu2000/research/umnl. The main contribution of Chapter 5 is the proposal of a new measure called locality surface to characterize locality of reference in programs. Sorenson et al. describe how a three-dimensional surface can be used to represent both of programs. In Chapter 6, Thornock et al.

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."

Available in PDF, EPUB and Kindle. Book excerpt: The study presents a formal model of multiprogrammed systems based on an empirical analysis of operations at a commercial teleprocessing installation. In particular, the study analyzes the interactive effects on system thruput of job mix, local (operator) scheduling, and monitor design in a multiprogrammed environment. The analysis shows that job mix effects considerably influence system performance and decreasing them will result in increased thruput. (Author).
Download or read book Workload Modeling for Computer Systems Performance Evaluation written by Dror G. Feitelson and published by Cambridge University Press. This book was released on 2015-03-23 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliable performance evaluations require the use of representative workloads. This is no easy task since modern computer systems and their workloads are complex, with many interrelated attributes and complicated structures. Experts often use sophisticated mathematics to analyze and describe workload models, making these models difficult for practitioners to grasp. This book aims to close this gap by emphasizing the intuition and the reasoning behind the definitions and derivations related to the workload models. It provides numerous examples from real production systems, with hundreds of graphs. Using this book, readers will be able to analyze collected workload data and clean it if necessary, derive statistical models that include skewed marginal distributions and correlations, and consider the need for generative models and feedback from the system. The descriptive statistics techniques covered are also useful for other domains.

Available in PDF, EPUB and Kindle. Book excerpt: Database Concurrency Control: Methods, Performance and Analysis is a review of developments in concurrency control methods for centralized database systems, with a quick digression into distributed databases and multicomputers, the emphasis being on performance. The main goals of Database Concurrency Control: Methods, Performance and Analysis are to succinctly specify various concurrency control methods; to describe models for evaluating the relative performance of concurrency control methods; to point out problem areas in earlier performance analyses; to introduce queuing network models to evaluate the baseline performance of transaction processing systems; to provide insights into the relative performance of transaction processing systems; to illustrate the application of basic analytic methods to the performance analysis of various concurrency control methods; to review transaction models which are intended to relieve the effect of lock contention; to provide guidelines for improving the performance of transaction processing systems due to concurrency control; and to point out areas for further investigation. This monograph should be of direct interest to computer scientists doing research on concurrency control methods for high performance transaction processing systems, designers of such systems, and professionals concerned with improving (tuning) the performance of transaction processing systems.
