Introduction Like many organisations we are interested in managing computer clusters as resources for carrying out computationally intensive tasks. In common with many University organisations our resources are heterogeneous and have to serve many purposes. Although we have been able to develop computational clusters where a tranche of nodes was entirely dedicated we believe it is highly attractive to support cluster management of resources that may fluctuate in number or availability at different times. This is important for management of local resources but is also an important foundation idea for sharing resources between different organisations. In this paper we report on our prototype cluster management framework using a tuple spaces model and show how a coordination management system can be set up independent of any communications mechanism needed for achieving high performance amongst nodes working on parallel jobs. The tuple space model widely popularised by Gelernter
