Page-based Distributed Shared Memory for OSF/DCE
Jerzy Brzeziński, Michał Szychowiak, Dariusz Wawrzyniak · 1996
Distributed shared memory systems strive to overcome the architectural limitations of shared memory computers and to make easier developing parallel programs in distributed environment. As is known, however, in order to meet these goals in practice many specific and difficult problems have to be solved. In this paper fundamentals of DSM systems' construction --- including basic design, mechanisms, memory consistency models, and problems --- are presented. Then, a general concept and hierarchical structure of page-based DSM system for UNIX and OSF/DCE platforms, has been proposed. Applications of the basic DCE components for improving security, modularity, scalability and portability of the proposed system, in comparison with the existing ones, have been described. 1 Introduction Generally, distributed computer systems are thought of as a collection of loosely coupled processing units (nodes, sites) interconnected by communication network. Nodes in a distributed systems are al...
