Clusters: A Pragmatic Approach Towards Supporting a Fine Grained Active Object Model in Distributed Systems

A powerful programming environment for developing distributed applications relies on its ability to abstract away the details of the underlying architecture and present a simplified view to the developer. Along the path to transparency and uniformity lies object orientation, a uniform fine-grained active object model and powerful semantic analysis to automate the partitioning, distribution and run-time control of the user's application. This paper presents a model of object composition known as clustering. The construction model, the mapping of clusters to a run-time specifically designed to support them, and related issues are described. 1 Background DIAMONDS is an environment for the development of distributed applications (under development at Syracuse) in which the dynamic association of resources to applications reflects algorithmic parallelism, computational needs, and the current state of the system[1]. In this system, networks of heterogeneous processors serve as a pool of com..
