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.Показать полностьюBeowulf 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.

This is the first, and still, the most comprehensive book to describe the sophisticated workings of the UNIX System V kernel — the internal algorithms, the structures that form the basis of the UNIX operating system, and their relationship to the programming interface.Показать полностьюThis is the first, and still, the most comprehensive book to describe the sophisticated workings of the UNIX System V kernel — the internal algorithms, the structures that form the basis of the UNIX operating system, and their relationship to the programming interface. System programmers will gain a better understanding of how the kernel works and will be able to compare algorithms used in the UNIX system to algorithms used in other operating systems. Programmers on UNIX systems will gain a deeper understanding of how their programs interact with the system and can thereby code more efficient programs.

The book has been updated to cover version 2.4 of the kernel, which is quite different from version 2.2: the virtual memory system is entirely new, support for multiprocessor systems is improved, and whole new classes of hardware devices have been added. You'll learn what conditions bring out Linux’s best performance, and how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments.

The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in what order. It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary for the relatively slow disks. The third edition of Understanding the Linux Kernel takes you on a guided tour of the most significant data structures, algorithms, and programming tricks used in the kernel. Probing beyond superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Important Intel-specific features are discussed. Relevant segments of code are dissected line by line. But the book covers more than just the functioning of the code; it explains the theoretical underpinnings of why Linux does things the way it does.

This pocket reference book is ideal for DBAs who need to have the specialized Unix database commands at their fingertips. Without wasting space on general Unix commands DBAs don't use, it concisely summarizes only what an Oracle DBA needs to know. This book is useful for DBAs currently working with Unix, and for those making the transition from Oracle under Windows NT/2000 to Oracle under Unix.

Written for experienced C programmers, but assuming no previous knowledge of threads, the book explains basic concepts such as asynchronous programming, the lifecycle of a thread, and synchronization. You then move to more advanced topics such as attributes objects, thread-specific data, and realtime scheduling. An entire chapter is devoted to "real code," with a look at barriers, read/write locks, the work queue manager, and how to utilize existing libraries. In addition, the book tackles one of the thorniest problems faced by thread programmers-debugging-with valuable suggestions on how to avoid code errors and performance problems from the outset.

Device drivers literally drive everything you're interested in — disks, monitors, keyboards, modems — everything outside the computer chip and memory.Показать полностьюDevice drivers literally drive everything you're interested in — disks, monitors, keyboards, modems — everything outside the computer chip and memory. And writing device drivers is one of the few areas of programming for the Linux operating system that calls for unique, Linux-specific knowledge. For years now, programmers have relied on the classic Linux Device Drivers from O'Reilly to master this critical subject. Now in its third edition, this bestselling guide provides all the information you'll need to write drivers for a wide range of devices. Over the years the book has helped countless programmers learn: how to support computer peripherals under the Linux operating system how to develop and write software for new hardware under Linux the basics of Linux operation even if they are not expecting to write a driver The new edition of Linux Device Drivers is better than ever. The book covers all the significant changes to Version 2.6 of the Linux kernel, which simplifies many activities, and contains subtle new features that can make a driver both more efficient and more flexible. Readers will find new chapters on important types of drivers not covered previously, such as consoles, USB drivers, and more. Best of all, you don't have to be a kernel hacker to understand and enjoy this book. All you need is an understanding of the C programming language and some background in Unix system calls. And for maximum ease-of-use, the book uses full-featured examples that you can compile and run without special hardware. Today Linux holds fast as the most rapidly growing segment of the computer market and continues to win over enthusiastic adherents in many application areas. With this increasing support, Linux is now absolutely mainstream, and viewed as a solid platform for embedded systems. If you're writing device drivers, you'll want this book. In fact, you'll wonder how drivers are ever written without it.

This is a book about UNIX programming. It starts with basic concepts and ends with coverage of advanced topics. It is a self-teaching guide, and yet it functions as a UNIX reference book.Показать полностьюThis is a book about UNIX programming. It starts with basic concepts and ends with coverage of advanced topics. It is a self-teaching guide, and yet it functions as a UNIX reference book. The examples provided are written in the C and C++ languages. The examples are short programs, each intended to demonstrate use of a particular programming facility. The C++ programs are written as simple programs and should be well understood by those that do not program in C++. This book attempts to be UNIX platform neutral. Throughout the book, differences in functionality are noted for your convenience. This will save you time when you must write projects that must be UNIX portable. FreeBSD 3.4 release is used throughout this book for demonstration purposes. This guarantees that the example programs will compile and run without any additional effort on that platform. This also grants a specific level of functionality, since some functions are lacking or vary on other platforms. You can obtain FreeBSD from the Internet or purchase it on a CD-ROM at a nominal cost. This allows you to work through the book on a platform that is on a par with other professional UNIX platforms.
