Abstract
The management of memory coherence is an important problem in distributed shared memory (DSM) system. In a cache-based coherence DSM system using linked list structure, the key to maintaining the coherence and improving system performance is how to manage the owner in the linked list. This paper presents the design of a new management protocol—NONH (New-Owner New-Head) and its performance evaluation. The analysis results show that this protocol can improve the scalability and performence of a coherent DSM system using linked list It is also suitable for managing the cache coherency in tree-like hierarchical architecture.
