Abstract : In this report we present the implementation of multicluster operation in the Cronus distributed computing environment. A cluster is a collection of hosts on one or more networks. Clusters are formed to organize and control the relationship between organizations for reasons of security and administration. This document presents the mechanisms to support intercluster object addressing; these mechanisms form the basis for multicluster operation. Object-oriented distributed computing environments strive to present a uniform environment for building distributed applications by providing host and network transparent access to resources. Previously, the Cronus distributed environment operated in an environment of different types of hosts executing across several local area networks connected by gateways. Cronus achieved a uniform environment by treating the set of hosts as a single system in terms of authentication and in binding object identifiers to their locations. To extend Cronus to large environments, it is necessary to decompose the environment into collections of hosts. Decomposition is crucial to system scalability. It speeds up the location of objects and reduces the number of global name spaces
