Amnon Barak, Shai Guday, Richard G Wheeler
R1,584 Discovery Miles 15 840 Ships in 10 - 15 working days

This book describes the design and internals of the MOSIX distributed operating system. MOSIX, an acronym for Multicomputer Operating System for UNIX, integrates a cluster of loosely integrated computers into a virtual single-machine UNIX environment. The main property of MOSIX is the high degree of integration among the processors, which may include personal workstations and shared memory and non-shared memory multiprocessors, connected by fast communication links. This integration includes network transparency, cooperation between the processors to provide services across machine boundaries, support of dynamic configuration, and system-initiated load balancing by process migration. Another property of MOSIX is the ability to scale up the system configuration to encompass a large number of computers. The development of MOSIX was begun in 1981. The book is intended primarily for readers who are interested in distributed and multiprocessor systems. The reader is assumed to have some knowledge in programming and operating systems, preferably UNIX. Readers without this background will still benefit from thetechniques and algorithms discussed.

Anyone who reads this book will learn how to use the features of UNIX, and how to modify and customize those features. It is organized in such a way that it leads the reader from the UNIX basics to the more complex and powerful concepts such as shell-programming and networking. Although the book is written as introduction and reference for the UNIX user, it can very well be used as a textbook in undergraduate computer science or computer engineering courses.

R2,889 Discovery Miles 28 890 Ships in 10 - 15 working days

Well suited to medium-scale general purpose computing, the Unix time sharing operating system is deservedly popular with academic institutions, research laboratories, and commercial establishments alike. Its user com munity, until recently a brotherhood of experienced computer profes sionals, it now attracting many people concerned with computer appli cations rather than the computer systems themselves. This book is intended for that new audience, people who have never encountered the Unix system before but who do have some acquaintance with computing. While helping beginning users get started is the primary aim of this book, it is also intended to serve as a handy reference subsequently. However, it is not designed to replace the definitive Unix system docu mentation. Unix operating systems now installed in computing centers, offices, and personal computers come in three related but distinct breeds: Seventh Edition Unix, Berkeley 4.2 BSD, and System V. These differ from each other in details, even though their family resemblance is strong. This book emphasizes System V, while paying heed to its two popular cousins. It also includes a few facilities in wide use, but not included in the normal system releases. Individual details, of course, must be found in the manuals supplied with each system."
