As computers become more complex, the number and complexity of the tasks facing the computer architect also increase. Computer performance often depends on the design parameters and intuition that must be supplemented by performance studies to enhance design productivity. Performance Modeling for Computer Architects introduces computer architects to computer system performance models and shows how they are relatively simple, inexpensive to implement, and sufficiently accurate for most purposes. The book discusses the development of performance models based on queuing theory and probability. The text also shows how performance models are used to provide quick approximate calculations to indicate basic performance trade-offs and to narrow the range of parameters considered when determining system configurations. Performance models can demonstrate how a memory system is to be configured, what the cache structure should be, and what effect incremental changes in cache size can have on the miss rate. A particularly deep knowledge of probability theory or any other mathematical field is not required to understand the papers in this volume.

In distributed computing systems--the software for networks--a system may have a huge number of components resulting in a high level of complexity. That and issues such as fault-tolerance, security, system management, and exploitation of concurrency make the development of complex distributed systems a challenge. The Isis Toolkit has become one of the most successful approaches for building reliable distributed software since its release in 1987. Commercially available since 1990, Isis is used in hundreds of settings, including the New York Stock Exchange, the Electronic Stock Exchange of Switzerland, the data acquisition system of the CERN high-energy physics particle accelerator, VLSI fabrication control systems, the Iridium telecommunication system, database applications at the World Bank, and an Arctic weather environment monitoring system. Isis is also widely used for instructional purposes. This book comprises papers that document Isis and describe its important applications. Many of these are previously unpublished papers that give a broad overview of Isis, provide details of the underlying protocols and theory, and discuss the best ways to exploit Isis features in real applications. This volume will be of use to practitioners developing Isis-based applications, to instructors using Isis in classroom settings, and to researchers who want a single reference source for this important approach to distributed computing.

This book is concerned exclusively with discrete-time queues and their applications to the performance modeling of communication and computer networks. Since most modern networks operate on the basis of time slotting, and transmit information in fixed length (packets or cells), it thus becomes natural to model such networks in discrete-time by associating a time slot in a physical network with the unit time in the corresponding discrete-time model. The book shows how, in this way, very accurate models that faithfully reproduce the stochastic behaviour of a communication or computer network can be constructed. The treatment is self contained, and progresses from basic probability theory and discrete-time queueing networks. These latter are applied to model the performance of numerous wide area satellite networks and local area networks, ranging in complexity from simple Aloha schemes to the timed token protocol of the FDDI network. The main objective of this book is to present a unified method for modeling any network access protocol as a discrete-time queueing network and t develop efficient solution techniques for these models. A significant number of the models and their solutions which are included have not previously appeared in the open literature. The text should prove useful to practitioners and researchers concerned with communication and computer network performance modeling, or anyone wanting a sound understanding of the application of discrete-time technique to this subject area.

This is the story of Microsoft(R) and how it rose to become the first monopoly of the information Age. The text is assembled from Ted Lewis's columns published in IEEE Computer (1994-1998), IEEE Internet Computing, and Scientific American. Microsoft Rising is a tale of great, emotion, and techno-marketing hype in one of the fastest growing, mainline industries of the world. It is an eye witness account to the changing computer industry and the story of Silicon Valley and how it works, a revisionist history of computing, circa 1990-2000. Microsoft Rising is ultimately about Microsoft's domination of the computer industry. This book reports the author's personal history through the early 1990's to the end of the decade. These stories often try to predict or explain the chaos of Silicon Valley. Lewis analyzes the industry and shows how high-technology industry is constantly changing in turmoil and upheaval. He also examines the art of software development and deals with innovation and the emergence of techno-society. The book does not promise any answers, but rather concludes this short journey into the recent past with a number of provoking ideas about the future of hi-tech.
