Different departments of large organization often maintain dedicated cluster systems for different computing loads. This paper has designed and implemented a cloud management system software-Phoenix Cloud to consolidate heterogeneous computing loads on shared cluster system. Furthermore, the paper has proposed a cooperative resource provision and management policy for large organization and its affiliated departments to share the aggregated cluster system. The experiments show: comparing with the case that each department maintains its dedicated cluster system, Phoenix Cloud enables the consolidation of scientific computing and information service; Moreover, Phoenix Cloud significantly decreases the scale of required cluster system for large organization, and improves the benefit of scientific computing department and its end users while provisioning enough resource to information service with varying load.
