Implementation of distributed orthogonal persistence using virtual memory / Francis Vaughan.

Abstract

This thesis explores the implementation of orthogonally persistent systems that make direct use of the attributes of paged virtual memory found in the majority of conventional computing platforms. These attributes are exploited to support object movement for persistent storage to addressable memory, to aid in garbage collection, to provide the illusion of larger storage spaces than the underlying architecture allows, and to provide distribution of the persistent system. It also explores the different models of distribution, communication mechanisms between federated spaces and the problem of maintaining consistency between separate persistent spaces in a manner which ensures both a reliable and resilient computational environment.
