Blocking locks are commonly used in parallel programs to improve application performance and system throughput. However, most implementations of such locks suffer from two major problems-latency and scalability. We propose an implementation of blocking locks using scheduler adaptation which exploits the interaction between thread schedulers and locks. By experimentation using well-known multiprocessor applications on a KSR2 multiprocessor, we demonstrate how such an implementation considerably reduces the latency, and improves the scalability of blocking locks
