The Synergy Between Non-blocking Synchronization and Operating System Structure

Non-blocking synchronization has significant advantages over blocking synchronization: however, it has not been used to a significant degree in practice. We designed and implemented a multiprocessor operating system kernel and run-time library for high-performance, reliability and modularity. We used non-blocking synchronization, not because it was an objective in itself, but because it became the approach of choice. It was an attractive approach because of the synergy between other structuring techniques we used to achieve our primary goals and the benefits of non-blocking synchronization.
