Supporting distributed applications in the Amadeus environment

Eiiel**: an Implementation of Eiiel on Amadeus, a Persistent, Distributed Applications Support Environment

Ei el is an implementation of Ei el which provides support for distribution persistence concurrency and transactions All objects in an Ei el system are global i e accessible from nodes other than that at which they are currently located and persistent i e their lifetimes are not bounded by the duration of the program that created them Some objects may also be atomic i e accesses to these object...

Supporting a CAD Framework on an Advanced Distributed System

This paper describes the use of a general purpose distributed object support platform, including an advanced action model, to support Computer Aided Design (CAD) applications. In particular, it describes the use of the Amadeus/RelaX platform to support the DASSY tool interface which, in turn, supports a range of cooperating CAD tools. The paper provides an overview of the Amadeus/RelaX platform...

Some Issues in Load Balancing in Amadeus

1 Overview This short position paper discusses some of the interesting issues that have arisen in the course of adding load balancing to Amadeus. Of particular interest is the Amadeus concept of a cluster and how it aaects both the granularity at which load balancing is performed and the way in which applications should be structured to achieve the maximum beneets. As a concrete example of this...

On Object Orientation as a Paradigm for General PurposeDistributed Operating

In the Amadeus project we have been considering the construction of a general purpose distributed support environment for object oriented programming. In this paper we tackle a number of key areas whose interaction must be addressed in the design of such a general purpose object support system: 1) integration of support for (object oriented) database systems; 2) integration of security mechanis...
