A Novel Elastic Resource Allocation Strategy of Virtual Cluster

Aiming at the problem on how to effectively allocate HPC resources to improve the efficiency of system, this paper presents a novel elastic resources allocation strategy. Within the changing range the users have assigned, the strategy permits the system to dynamically adjust the resource distribution of virtual clusters so that the efficiency of the system can be improved and users´ costs can be reduced. To better implement the strategy, this paper provides a detailed description about the issue of resource allocation, and then proposes a algorithm named Mixed Bin Packing Algorithm. Experimental results indicate that the Mixed Bin Packing Algorithm is more effective than the previous algorithms, especially in a large application scale background.
