Focusing on the design and implementation of the operating system itself — not on the applications and tools that run on it -- this book compares and analyzes the alternatives offered by several important UNIX variants, and covers several advanced subjects, such as multi-processors and threads.

Compares several important UNIX variants—highlighting the issues and alternative solutions for various operating system components. Describes advanced technologies such as multiprocessor and multithreaded systems, log- structured file systems, and modern memory architecture. Table of Contents Introduction. The Mandate For Change.
