The Perfect bureaucrat is the man who manages to make no decisions and escapes all responsibility. Summary The CentiJ system synthesizes Java source code that funnels invocations through an RMI (Remote Method Invocation) based transport layer for distributed computation. The technique generates bridge pattern code (i.e., interfaces and proxies) that automate the creation of virtual proxies for ...

This paper presents a distributed N-body method based on an adaptive collaborative system model. The collaborative system is built with the distributed objects in a cluster. It can be reconfigured during the computation to fully utilize the computing power of the cluster. The method is implemented in Java and RMI to support distributed computing on heterogeneous platforms. A distributed tree st...

aspect ServerSide { abstract pointcut facadeMainExecution(); abstract Remote initFacadeInstance(); abstract String getSystemName(); abstract String getServerName(); Those abstract methods and pointcut are implemented by system specific aspects. The abstract aspect also defines and around advice that uses the abstract methods to export the facade instance and make it remotely available. Copyrigh...

Distributed applications rely on middleware to enable interaction among remote components. Thus, the overall performance increasingly depends on the interplay between the implementation of application components and the features provided by the middleware. In this paper we analyze Java components interacting through the RMI middleware, and we discuss opportunities for optimizing remote method i...

In many distributed systems applications deployed on the worldwide scale, it is latency, rather than bandwidth, that is the primary determinant of performance. This paper describes Ambassadors, a communication technique using mobile Java objects within an RPC/RMI-like communication structure. Ambassadors minimise the aggregate latency of sequences of inter-dependent remote operations by migrati...

A plug-and-play (PaP) architecture to be applied for specification and execution of telecommunication systems functionality is presented. The architecture is based on a theatre metaphor. Plays define the functionality of the system. PaP components are realised by actors playing roles defined by manuscripts. An actor's capabilities define his possibilities for playing various roles. The usabilit...
