Written for both the computer layperson and the experienced programmer, this book explores the tenets of the UNIX operating system in detail, dealing with powerful concepts in a comprehensive, straightforward manner.

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.

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."
