Download or read book Applied System Simulation written by Mohammad S. Obaidat and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simulation and molding are efficient techniques that can aid the city and regional planners and engineers in optimizing the operation of urban systems such as traffic light control, highway toll automation, consensus building, public safety, and environmental protection. When modeling transportation systems such as freeway systems, arterial or downtown grid systems, the city planner and engineer is concerned with capturing the varied interactions between drivers, automobiles, and the infrastructure. Modeling and simulation are used to effectively optimize the design and operation of all of these urban systems. It is possible that in an urban simulation community workshop, citizens can work interactively in front of computers and be able using the click of the mouse to walk up to their own front porch, looking at the proposed shopping mall alternatives across the street from virtually any angle and proposed bridge or tunnel and see how it can reduce traffic congestion. Buildings can be scaled down or taken out, their orientation can be changed in order to check the view and orientation in order to have better site with efficient energy-conservation. The stone or brick material on a building can be replaced by colored concrete, or more trees and lampposts can be placed on the site. Such flexibility in simulation and animation allows creative ideas in the design and orientation of urban sites to be demonstrated to citizens and decision makers before final realization.

Book Synopsis Computer Architecture Performance Evaluation Methods by : Lieven Eeckhout
Download or read book Computer Architecture Performance Evaluation Methods written by Lieven Eeckhout and published by Springer Nature. This book was released on 2022-05-31 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance evaluation is at the foundation of computer architecture research and development. Contemporary microprocessors are so complex that architects cannot design systems based on intuition and simple models only. Adequate performance evaluation methods are absolutely crucial to steer the research and development process in the right direction. However, rigorous performance evaluation is non-trivial as there are multiple aspects to performance evaluation, such as picking workloads, selecting an appropriate modeling or simulation approach, running the model and interpreting the results using meaningful metrics. Each of these aspects is equally important and a performance evaluation method that lacks rigor in any of these crucial aspects may lead to inaccurate performance data and may drive research and development in a wrong direction. The goal of this book is to present an overview of the current state-of-the-art in computer architecture performance evaluation, with a special emphasis on methods for exploring processor architectures. The book focuses on fundamental concepts and ideas for obtaining accurate performance data. The book covers various topics in performance evaluation, ranging from performance metrics, to workload selection, to various modeling approaches including mechanistic and empirical modeling. And because simulation is by far the most prevalent modeling technique, more than half the book's content is devoted to simulation. The book provides an overview of the simulation techniques in the computer designer's toolbox, followed by various simulation acceleration techniques including sampled simulation, statistical simulation, parallel simulation and hardware-accelerated simulation.

Book Synopsis Massively Parallel Algorithms for Trace-driven Cache Simulations by : David M. Nicol
Download or read book Massively Parallel Algorithms for Trace-driven Cache Simulations written by David M. Nicol and published by . This book was released on 1991 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Trace-driven cache simulation is central to computer design. A trace is a very long sequence, x1 ..., x[subscript N], of references to lines (contiguous locations) from main memory. At the t[superscript th] instant, reference x[subscript t] is hashed into a set of cache locations, the contents of which are then compared with x[subscript t]. If at the t[superscript th] instant x[subscript t] is not present in the cache, then it is said to be a miss, and is loaded into the cache set, possibly forcing the replacement of some other memory line, and making x[subscript t] present for the (t + 1)[superscript st] instant. The problem of parallel simulation of a subtrace of N references directed to a C line cache set is considered, with the aim of determining which references are misses and related statistics. A simulation method is presented for the Least-Recently-Used (LRU) policy, which regardless of the set size C runs in time O(log N) using N processors on the exclusive read, exclusive write (EREW) parallel model. A simpler LRU simulation algorithm is given that runs in O(C log N) time using N/log N processors. We present timings of the second algorithm's implementation on the MasPar MP-1, a machine with 16384 processors. A broad class of reference-based line replacement policies are considered, which includes LRU as well as the Least-Frequently-Used and Random replacement policies. A simulation method is presented for any such policy that on any trace of length N directed to a C line set runs in time O(C log N) time with high probability using N processors on the EREW model. The algorithms are simple, have very little space overhead, and are well-suited for SIMD implementations."

Book Synopsis Cache Analysis in a Multiprocess Environment Using Execution Driven Simulation by : John H. Fraser, III
Download or read book Cache Analysis in a Multiprocess Environment Using Execution Driven Simulation written by John H. Fraser, III and published by . This book was released on 1996-08-01 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cache memory is commonly used to bridge the gap between microprocessor and memory speeds. A wide variety of cache designs are possible, so some method is required to evaluate the benefits and costs of the various alternatives. Trace driven simulation is commonly used by the computer architecture community to analyze potential designs. Traces of benchmark execution are applied to a model of the design under study. Most of today's computer systems have been optimized based on results of these studies. One important aspect that is frequently ignored in trace driven studies is the effect of the operating system and multiprogramming on cache performance; most traces consist only of a single program's execution. It has been acknowledged in the past that this overhead introduces interference which limits the benefits of new designs, but evaluations using multiprogrammed traces have been neglected due to the lack of readily available tools that can capture such traces. In this research we describe a new tracing system that allows the capture of both operating system and multiprogrammed execution data. Cache performance is studied using multiprogrammed traces of the SPEC benchmarks. We study the effects of considering multiple tasks on the cache miss rate. The performance variation is primarily due to the presence of context switches. In an attempt to extend this work, we develop an analytical model that is used to synthetically incorporate context switches into a single process trace. We have found that the operating system introduces a small but persistent overhead to cache performance Additional processes have an even greater impact, which increases as the level of multi-tasking increases. Spatial locality is not significantly affected by these conditions, but the temporal locality of a program is substantially reduced by the presence of context switches.
Book Synopsis Foundations of Dependable Computing by : Gary M. Koob
Download or read book Foundations of Dependable Computing written by Gary M. Koob and published by Springer Science & Business Media. This book was released on 2007-07-23 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foundations of Dependable Computing: Models and Frameworks for Dependable Systems presents two comprehensive frameworks for reasoning about system dependability, thereby establishing a context for understanding the roles played by specific approaches presented in this book's two companion volumes. It then explores the range of models and analysis methods necessary to design, validate and analyze dependable systems. A companion to this book (published by Kluwer), subtitled Paradigms for Dependable Applications, presents a variety of specific approaches to achieving dependability at the application level. Driven by the higher level fault models of Models and Frameworks for Dependable Systems, and built on the lower level abstractions implemented in a third companion book subtitled System Implementation, these approaches demonstrate how dependability may be tuned to the requirements of an application, the fault environment, and the characteristics of the target platform. Three classes of paradigms are considered: protocol-based paradigms for distributed applications, algorithm-based paradigms for parallel applications, and approaches to exploiting application semantics in embedded real-time control systems. Another companion book (published by Kluwer) subtitled System Implementation, explores the system infrastructure needed to support the various paradigms of Paradigms for Dependable Applications. Approaches to implementing support mechanisms and to incorporating additional appropriate levels of fault detection and fault tolerance at the processor, network, and operating system level are presented. A primary concern at these levels is balancing cost and performance against coverage and overall dependability. As these chapters demonstrate, low overhead, practical solutions are attainable and not necessarily incompatible with performance considerations. The section on innovative compiler support, in particular, demonstrates how the benefits of application specificity may be obtained while reducing hardware cost and run-time overhead.
Book Synopsis Performance Modeling for Computer Architects by : C. M. Krishna
Download or read book Performance Modeling for Computer Architects written by C. M. Krishna and published by John Wiley & Sons. This book was released on 1995-10-14 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: As computers become more complex, the number and complexity of the tasks facing the computer architect have increased. Computer performance often depends in complex way on the design parameters and intuition that must be supplemented by performance studies to enhance design productivity. This book introduces computer architects to computer system performance models and shows how they are relatively simple, inexpensive to implement, and sufficiently accurate for most purposes. It discusses the development of performance models based on queuing theory and probability. The text also shows how they are used to provide quick approximate calculations to indicate basic performance tradeoffs and narrow the range of parameters to consider when determining system configurations. It illustrates how performance models can demonstrate how a memory system is to be configured, what the cache structure should be, and what incremental changes in cache size can have on the miss rate. A particularly deep knowledge of probability theory or any other mathematical field to understand the papers in this volume is not required.

Book Synopsis Analysis of Cache Performance for Operating Systems and Multiprogramming by : Agarwal
Download or read book Analysis of Cache Performance for Operating Systems and Multiprogramming written by Agarwal and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: As we continue to build faster and fast. er computers, their performance is be coming increasingly dependent on the memory hierarchy. Both the clock speed of the machine and its throughput per clock depend heavily on the memory hierarchy. The time to complet. e a cache acce88 is oft. en the factor that det. er mines the cycle time. The effectiveness of the hierarchy in keeping the average cost of a reference down has a major impact on how close the sustained per formance is to the peak performance. Small changes in the performance of the memory hierarchy cause large changes in overall system performance. The strong growth of ruse machines, whose performance is more tightly coupled to the memory hierarchy, has created increasing demand for high performance memory systems. This trend is likely to accelerate: the improvements in main memory performance will be small compared to the improvements in processor performance. This difference will lead to an increasing gap between prOCe880r cycle time and main memory acce. time. This gap must be closed by improving the memory hierarchy. Computer architects have attacked this gap by designing machines with cache sizes an order of magnitude larger than those appearing five years ago. Microproce880r-based RISe systems now have caches that rival the size of those in mainframes and supercomputers.
Book Synopsis Workload Modeling for Computer Systems Performance Evaluation by : Dror G. Feitelson
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.
Book Synopsis Performance Evaluation and Benchmarking by : Lizy Kurian John
Download or read book Performance Evaluation and Benchmarking written by Lizy Kurian John and published by CRC Press. This book was released on 2018-10-03 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer and microprocessor architectures are advancing at an astounding pace. However, increasing demands on performance coupled with a wide variety of specialized operating environments act to slow this pace by complicating the performance evaluation process. Carefully balancing efficiency and accuracy is key to avoid slowdowns, and such a balance can be achieved with an in-depth understanding of the available evaluation methodologies. Performance Evaluation and Benchmarking outlines a variety of evaluation methods and benchmark suites, considering their strengths, weaknesses, and when each is appropriate to use. Following a general overview of important performance analysis techniques, the book surveys contemporary benchmark suites for specific areas, such as Java, embedded systems, CPUs, and Web servers. Subsequent chapters explain how to choose appropriate averages for reporting metrics and provide a detailed treatment of statistical methods, including a summary of statistics, how to apply statistical sampling for simulation, how to apply SimPoint, and a comprehensive overview of statistical simulation. The discussion then turns to benchmark subsetting methodologies and the fundamentals of analytical modeling, including queuing models and Petri nets. Three chapters devoted to hardware performance counters conclude the book. Supplying abundant illustrations, examples, and case studies, Performance Evaluation and Benchmarking offers a firm foundation in evaluation methods along with up-to-date techniques that are necessary to develop next-generation architectures.
