OpenVMS Alpha Internals and Data Structures: Memory Management is an update
to selected parts of the book OpenVMS AXP Internals and Data Structures Version 1.5 (Digital Press, 1994). This book covers the extensions to the memory management subsystem of OpenVMS Alpha to allow the operating system and applications to access 64 bits of address space. It emphasizes system data structures and their manipulation by paging and
swapping routines and related system services.
It also describes management of dynamic memory, such as nonpaged pool, and support for nonuniform memory access (NUMA) platforms.
This book is intended for systems programmers, technical consultants, application designers, and other computer progressions interested in learning the details of the OpenVMS executive. Teachers and students of graduate and advanced undergraduate courses in operating systems will find this book a valuable study in how theory and practice are resolved in a complex commercial
operating system.

Dealing with system problems from user login failures to server crashes--is a critical part of a system administrator's job. A down system can cost a business thousands of dollars per minute. But there is little or no information available on how to troubleshoot and correct system problems; in most cases, these skills are learned in an ad-hoc manner, usually in the pressure-cooker environment of a crisis. This is the first book to address this lack of information.
The authors (both experienced Tru64 UNIX support engineer for Compaq) systematically present the techniques and tools needed to find and fix system problems. The first part of the book presents the general principles and techniques needed in system troubleshooting. These principles and techniques are useful not only for UNIX system administrators, but for anyone who needs to find and fix system problems. After this foundation, the authors describe troubleshooting tools used in the UNIX environment. The remainder of the book covers specific areas of the Tru64 UNIX operating system in detail: listing common problems, their causes, how to detect them, and how to correct them. Each chapter includes a "Before You Call Support" section that details the most important things to check and correct before it's necessary to call Compaq technical support. The authors also include decision trees to help the reader systematically isolate particular problem types.

OpenVMS professionals have long enjoyed a robust, full-featured operating system running the most mission-critical applications in existence. However, many of today's graduates may not yet have had the opportunity to experience it for themselves. Intended for an audience with some knowledge of operating systems such as Windows, UNIX and Linux, Getting Started with OpenVMS introduces the reader to the OpenVMS approach.

Part 1 is a practical introduction to get the reader started using the system. The reader will learn the OpenVMS terminology and approach to common concepts such as processes and threads, queues, user profiles, command line and GUI interfaces and networking. Part 2 provides more in-depth information about the major components for the reader desiring a more technical description. Topics include process structure, scheduling, memory management and the file system. Short sections on the history of OpenVMS, including past, present, and future hardware support (like the Intel Itanium migration), are included. OpenVMS is considered in different roles, such as a desktop system, a multi-user system, a network server, and in a combination of roles.

Comprehensive guides to the latest Beowulf tools and methodologies. Beowulf clusters, which exploit mass-market PC hardware and software in conjunction with cost-effective commercial network technology, are becoming the platform for many scientific, engineering, and commercial applications. With growing popularity has come growing complexity. Addressing that complexity, Beowulf Cluster Computing with Linux and Beowulf Cluster Computing with Windows provide system users and administrators with the tools they need to run the most advanced Beowulf clusters. The book is appearing in both Linux and Windows versions in order to reach the entire PC cluster community, which is divided into two distinct camps according to the node operating system. Each book consists of three stand-alone parts. The first provides an introduction to the underlying hardware technology, assembly, and configuration. The second part offers a detailed presentation of the major parallel programming librairies. The third, and largest, part describes software infrastructures and tools for managing cluster resources. This includes some of the most popular of the software packages available for distributed task scheduling, as well as tools for monitoring and administering system resources and user accounts. Approximately 75% of the material in the two books is shared, with the other 25% pertaining to the specific operating system. Most of the chapters include text specific to the operating system. The Linux volume includes a discussion of parallel file systems.

The papers present in this text survey both distributed shared memory (DSM) efforts and commercial DSM systems. The book discusses relevant issues that make the concept of DSM one of the most attractive approaches for building large-scale, high-performance multiprocessor systems. The authors provide a general introduction to the DSM field as well as a broad survey of the basic DSM concepts, mechanisms, design issues, and systems.

The book concentrates on basic DSM algorithms, their enhancements, and their performance evaluation. In addition, it details implementations that employ DSM solutions at the software and the hardware level. This guide is a research and development reference that provides state-of-the art information that will be useful to architects, designers, and programmers of DSM systems.

In the early days of computing, technicians in white coats controlled refrigerator-sized computers housed in sealed rooms, far from ordinary users. Today, computers are inexpensive commodities, like television sets,
and ordinary people control and interact with them. This new paradigm has led to a burgeoning demand for graphics-intensive and highly interactive interfaces.

Developing User Interfaces is targeted at the programmer who will actually implement, rather than design, the user interface. Most user interface books focus on psychology and usability, not programming techniques. This book recognizes the need for programmers to collaborate with usability experts and psychologists, so topics such as the principles of visualization, human perception, and usability evaluation are touched upon. Yet the primary focus remains on those tools and techniques required for programming the complex user interface.

* Focuses on advanced programming topics
* event handling
* interaction with geometric objects
* widget tool kits
* input syntax
* Useful to programmers using any language no particular windowing system or tool kit is presumed, examples are drawn from a variety of commercial systems, and code examples are presented in pseudo code
* The basic concepts of traditional computer graphics such as drawing and three-dimensional modeling are covered for readers without a computer graphics background."

This book presents an extensive survey and report of related research on important developments in cellular automata (CA) theory. The authors introduce you to this theory in a comprehensive manner that will help you understand the basics of CA and be prepared for further research. They illustrate the matrix algebraic tools that characterize group CA and help develop its applications in the field of VLSI testing.
The text examines schemes based on easily testable FSM, bit-error correcting code, byte error correcting code, and characterization of 2D cellular automata. In addition, it looks into CA-based universal pattern generation, data encryption, and synthesis of easily testable combinational logic. The book covers new characterizations of group CA behavior, CA-based tools for fault diagnosis, and a wide variety of applications to solve real-life problems.

This text is an introduction to the design and implementation of various types of system software. A central theme of the book is the relationship between machine architecture and systems software.
