CLUSTER SYSTEM, CONTROLLER, METHOD FOR CONTROLLING, AND COMPUTER-READABLE RECORDING MEDIUM HAVING STORED THEREIN CONTROLLING PROGRAM

摘要

The cluster system including a generator that generates reference information in which an estimated consumption power and an estimated performance of a cluster including two or more candidate nodes among the plurality of nodes when the candidate nodes are assumed to be operated at respective load setting values are associated with each other for each of a plurality of combinations of the respective load setting values of the candidate nodes; a load setting value selector that selects a combination of the respective load setting values of the candidate nodes, the combination leading to the estimated performance satisfying a required performance for the cluster and having the lowest consumption power, by referring to the reference information; and an operation controller that operates the candidate nodes at the selected combination of the load setting values. This configuration satisfies the required performance and also reduce the consumption power.
