Transparent adaptation of sharing granularity in Multi View-based DSM systems

摘要

In this paper we propose a mechanism that provides distributed shared memory (DSM) systems with a flexible sharing granularity. The size of the shared memory units is dynamically determined by the system during runtime. This size can range from that of a single variable up to the size of the entire shared memory space. During runtime, the DSM transparently adapts the granularity to the memory access pattern of the application in each phase of this execution. This adaptation, called Composed View, provides efficient data sharing in software DSM while preserving sequential consistency.
