Engineering Distributed Shared Memory Middleware for Java

Abstract

Abstract. This paper describes the design, implementation and initial evaluation of an object-based Distributed Shared Memory (DSM) middleware system for Java. The resulting implementation allows the construction of event-based distributed systems using a simple programming model, allowing applications to be deployed without hardware or communication channel assumptions. Our implementation utilises standard, freely available, Message Oriented Middleware (MOM). This approach eases DSM development as many reliability and scalability issues associated to DSM may be handled by MOM. In addition to an implementation description, we provide performance results of a prototype system on a Local Area Network.

Merging the Publish-Subscribe Pattern with the Shared Memory Paradigm

“…There is no third-party application nor user code that can be called on such event. Event-based programming can be used to implement a DSM, as proposed in this system [13], which describes a DSM implemented using the Java event-based distributed system. Our contribution is to implement an event-based distributed system on top of the S-DSM, which is the opposite approach.…”
