Abstract	Shared virtual memory is a software technique to provide shared memory on a network of computers without special hardware support. Although several relaxed consistency models and implementations are quite effective, there is still a considerable performance gap between the "software-only" approach and the hardware approach that uses directory-based caches. Automatic update is a simple communication mechanism, implemented in the SHRIMP multicomputer, that forwards local writes to remote memory transparently. In this paper we propose a new lazy release consistency based protocol, called Automatic Update Release Consistency (AURC), that uses automatic update to propagate and merge shared memory modifications. We compare the performance of this protocol against a software-only LRC implementation on several Splash2 applications and show that the AURC approach can substantially improve the performance of LRC. For 16 processors, the average speedup has increased from 5.9 under LRC, to 8.3 under AURC.
