Algorithms For Concurrent Systems 821

The field of concurrent computing has gained in importance after major chip manufacturers switched their focus from increasing the speed of individual processors to increasing the number of processors on a chip. The computer industry has thus been calling for a software revolution: the concurrency revolution. A major challenge underlying this paradigm shift is creating a library of abstractions that developers can use for general purpose concurrent programming. We study in this book how to define and build such abstractions in a rigorous manner. We focus on those that are considered the most difficult to get right and have the highest impact on the overall performance of a program: synchronization abstractions, also called shared objects or concurrent data structures. The book is intended for software developers and students. It began as a set of lecture notes for courses given at EPFL, Saarland University, Technical University of Berlin, and Télécom ParisTech.
