The Little Book of Semaphores (2nd Edition): The Ins and Outs of Concurrency Control and Common Mistakes
The Little Book of Semaphores is a textbook that introduces the principles of synchronization for concurrent programming. In most computer science curricula, synchronization is a module in an Operating Systems class. OS textbooks present a standard set of problems with a standard set of solutions, but most students don't get a good understanding of the material or the ability to solve similar problems. The approach of this book is to identify patterns that are useful for a variety of synchronization problems and then show how they can be assembled into solutions. After each problem, the book offers a hint before showing a solution, giving students a better chance of discovering solutions on their own. The book covers the classical problems, including "Readers-writers," "Producer-consumer," and "Dining Philosophers." In addition, it collects a number of not-so-classical problems. *** Published under the terms of the GNU Free Documentation License.
