Abstract

Distributed systems communicating by means of a distributed shared memory offer an interesting alternative to remote invocation systems. State-of-the art middleware like .net or J2EE offers almost transparent access to distributed objects on a variety of hardware platforms. However, the generated programs and the associated development environments are often heavyweight and slow. This article presents concepts and experience from the implementation of page-based DSM operating system. The system is intended for a variety of network computing applications in particular for multiplayer games, real-time systems and for application services in future mobile environments.
