Despite the fact that non-dedicated clusters have been installed within many environments, they are not commonly used for parallel processing. The lack of a Single System Image (SSI) is a major obstacle for clusters being routinely employed by ordinary engineers, managers, and accountants; and supporting next generation application software on non dedicated clusters. The provision of a SSI means that the software developer sees the whole cluster as a single powerful and reliable computer rather than as a set of personal computers connected by a network, and where resources are added, removed or reconfigured manually. We show that SSI clusters could be achieved through SSI operating systems. The provision of a SSI is essential if the complexity of a cluster of computers is to be concealed from developers so that they can concentrate on their application software.
