VioCluster: Virtualization for Dynamic Computational Domains

A large organization, such as a university, commonly supplies computational power through multiple independently administered computational domains (e.g. Clusters). Each computational domain faces the conflict between dynamic workload and static capacity. This is clearly inefficient at times when some clusters have idle nodes while others experience excessive workload. An opportunity arises to resolve this conflict by dynamically adapting the capacity of clusters by borrowing idle machines of peer domains. This paper presents the design, implementation, and evaluation of VioCluster, a virtualization based computational resource sharing platform.
