On virtual page-based and object-based memory managements in distributed environments

Responsibility for management of the main memory of each machine in a network of workstations has migrated from the paging concept to an object structure. We propose a new hybrid memory management mechanism that combines the advantages of both pages and objects while avoiding their disadvantages. Our approach is based on the inherent relationship among objects for caching different type of remote pages and objects. High-profile and low-profile objects with their respective h-cache and h-cache axe introduced. We implemented our technique through simulation and showed that it dramatically reduces miss-penalties and outperforms earlier methods.
