Lazy Release Consistency for Software Distributed Shared Memory

Lazy Release Consistency for Software Distributed Shared Memory
Relaxed memory consistency models, such as release consistency, were introduced in order to reduce the impact of remote memory access latency in both software and hardware distributed shared memoryDSM. However, in a software DSM, it is also important to reduce the number of messages and the amount of data exchanged for remote memory access. Lazy release consistency is a new algorithm for implementing release consistency that lazily pulls modi cations across the interconnect only when necessary. Trace-driven simulation using the SPLASH benchmarks indicates that lazy release consistency reduces both the number of messages and the amount of data transferred between processors. These reductions are especially signi cant for programs that exhibit false sharing and make extensive use of locks.
