Abstract

To achieve a stable operation of a cluster system by a combination of optimum nodes, in a warranty period of the cluster system.SOLUTION: Based on estimated power consumption at each candidate node which can constitute a cluster system, estimation performance, and specifications changing according to an operation time of each candidate node, combinations of candidate nodes are extracted in which response performance of the cluster system satisfies required performance and a residual life of each candidate node satisfies a warranty period of the cluster system, and out of the extracted combinations of candidate nodes, the combination of the candidate nodes that can minimize the power consumption of the cluster system is selected as a plurality of nodes of the cluster system.SELECTED DRAWING: Figure 6
