Book Description
A problem of memory and processor allocation to competing programs in time-sharing environment is investigated. Two level (core and auxiliary) paged memory system is studied. An analytic model of CPU time needed (instructions executed) and memory required (pages needed) is proposed as an approximation to actual program behavior. Specific probability distributions are postulated for CPU time needed and memory required; these are used in studying memory and processor allocation. Program behavior (execution) in paging environment is modeled; a memory-use estimator function is derived (page size dependence of this function is explicitly included). This model conforms to previous results established in simulation studies of program behavior. Based on memory-use estimator function, paging characteristics of a single program and the system under multiprogramming are studied. (Author Modified Abstract).

Book Description
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 Description
Staticanalysisisaresearchareaaimedatdevelopingprinciplesandtoolsforv- i?cation and semantics-based manipulation of programs and high-performance implementations of programming languages. The series of Static Analysis s- posia has served as the primary venue for presentation and discussion of th- retical, practical, and application advances in the area. This volume contains the papers accepted for presentation at the 10th - ternational Static Analysis Symposium (SAS 2003),which was held June 11–13, 2003 in San Diego, California, USA. Firmly established as a leading forum in the static analysis area, SAS 2003 received 82 high-quality submissions. Each paper was carefully reviewed, being judgedaccordingtoscienti?cquality,originality,andrelevancetothesymposium topics. Following on-line discussions, the program committee met in Paris, France, ́ at the Ecole Normale Sup ́ erieure on March 15, 2003, and selected 25 papers. In addition to the contributed papers, this volume includes an invited paper by Manuel Hermenegildo (Technical University of Madrid and University of New Mexico)and the abstractof aninvited talk by KenMcMillan (Cadence Berkeley Laboratories). On behalf of the Program Committee and the General Chair, I would like to thank the authors of the submitted papers, and the external referees, who p- vided timely and signi?cant reviews. I owe special thanks to Jacques Beigbeder ́ from Ecole Normale Sup ́ erieure for managing the submission site and the dev- opers of CyberChair for the use of their software. On this occasion, SAS was sponsored by the Association for Computing - chinery(ACM) andwasheld aspartofthe FederatedComputing ResearchC- ference (FCRC 2003). I would like to thank all organizing committee members for all their tremendous work.

Book Description
This book is an introduction to analytical performance modeling for computer systems, i.e., writing equations to describe their performance behavior. It is accessible to readers who have taken college-level courses in calculus and probability, networking, and operating systems. This is not a training manual for becoming an expert performance analyst. Rather, the objective is to help the reader construct simple models for analyzing and understanding the systems in which they are interested. Describing a complicated system abstractly with mathematical equations requires a careful choice of assumptions and approximations. These assumptions and approximations make the model tractable, but they must not remove essential characteristics of the system, nor introduce spurious properties. To help the reader understand the choices and their implications, this book discusses the analytical models in 20 research papers. These papers cover a broad range of topics: processors and disks, databases and multimedia, worms and wireless, etc. An Appendix provides some questions for readers to exercise their understanding of the models in these papers. Table of Contents: Preliminaries / Concepts and Little's Law / Single Queues / Open Systems / Markov Chains / Closed Systems / Bottlenecks and Flow Equivalence / Deterministic Approximations / Transient Analysis / Experimental Validation and Analysis / Analysis with an Analytical Model

Book Description
Data Access and Storage Management for Embedded Programmable Processors gives an overview of the state-of-the-art in system-level data access and storage management for embedded programmable processors. The targeted application domain covers complex embedded real-time multi-media and communication applications. Many of these applications are data-dominated in the sense that their cost related aspects, namely power consumption and footprint are heavily influenced (if not dominated) by the data access and storage aspects. The material is mainly based on research at IMEC in this area in the period 1996-2001. In order to deal with the stringent timing requirements and the data dominated characteristics of this domain, we have adopted a target architecture style that is compatible with modern embedded processors, and we have developed a systematic step-wise methodology to make the exploration and optimization of such applications feasible in a source-to-source precompilation approach.

Book Description
The NATO Advanced Study Institute on "Computer algorithms for solving linear algebraic equations: the state of the art" was held September 9-21, 1990, at II Ciocco, Barga, Italy. It was attended by 68 students (among them many well known specialists in related fields!) from the following countries: Belgium, Brazil, Canada, Czechoslovakia, Denmark, France, Germany, Greece, Holland, Hungary, Italy, Portugal, Spain, Turkey, UK, USA, USSR, Yugoslavia. Solving linear equations is a fundamental task in most of computational mathematics. Linear systems which are now encountered in practice may be of very large dimension and their solution can still be a challenge in terms of the requirements of accuracy or reasonable computational time. With the advent of supercomputers with vector and parallel features, algorithms which were previously formulated in a framework of sequential operations often need a completely new formulation, and algorithms that were not recommended in a sequential framework may become the best choice. The aim of the ASI was to present the state of the art in this field. While not all important aspects could be covered (for instance there is no presentation of methods using interval arithmetic or symbolic computation), we believe that most important topics were considered, many of them by leading specialists who have contributed substantially to the developments in these fields.
