요약

The application of mutual exclusion in order to protect shared data from concurrent access is a recurring programming pattern found in contemporary application software. Although alternatives to blocking synchronisation like lock-free programming solve several critical problems and offer better progress guarantees, they have not become as popular. This especially applies to operating system kernels that provide support for multiprocessing environments. In this Talk we give an overview over our design and implementation of an operating system kernel which is based solely on non-blocking algorithms. It provides a completely lock-free runtime system for object-oriented programming languages that support concurrency and automatic memory management. Abandoning the preemptive scheduler prevalent in many modern operating systems in favour of a compiler-guaranteed cooperative multitasking presents a novel approach to lock-free programming and enables several practical and beneficial non-blocking programming techniques such as processor-local storage
