Cluster architectures are cost effective alternatives to supercomputers. Built on the backbone of computer networks, they can be scaled up or down according to distributed applications requirements. An ad hoc cluster is temporarily organized as a virtual parallel machine for solving demanding applications. Its resources are gathered by the means of a name/directory or discovery process. In this paper, we review major existing name, directory and discovery services, and describe a distributed approach to resource discovery and management, based on a population of interacting mobile agents. This system has several advantages, like flexibility, scalability, robustness and transparency. Moreover, it guarantees to include in the dynamic cluster architecture only the resources that increase system performances.
