Distributed Shared Memory : A Page-Based Approach

In 1986, Kai Li's PhD thesis, "Shared Virtual Memory on Loosely Coupled Microprocessors," introduced the concept of Distributed Shared (DSM) systems, which has since facilitated further research in this field. One approach to implementing DSM distributed systems is page-based method, utilizes virtual memory techniques map pages a process' address space onto physical multiple nodes. The system automatically moves between nodes as needed, ensuring coherence and consistency for shared page updates. Page-based offers several advantages, including improved performance due reduced communication overhead better data locality, simplified programming models that resemble centralized scalability by allowing additional join expand capacity. However, its suitability certain depends their specific requirements characteristics. been applied various high- computing, cloud databases. Nonetheless, remote access overheads, cache issues, necessity well-connected network remain potential limitations approach. Key words: memory, Paging, coherence,
