PROBLEM TO BE SOLVED: To provide an information processing apparatus in which operation efficiency of a cluster system is improved.SOLUTION: A load calculation unit calculates periodically a load amount indicative of a load in a prescribed unit time as a self node load amount. A load mount accumulation unit receives a load amount calculated by a failover destination candidate node so as to accumulate it as a candidate node load amount together with the self node load amount. A load amount prediction unit calculates, on the basis of the self node load amount and the candidate node load amount, a predicted load amount after a point of time at which the self node load amount is calculated. A failover destination selecting unit selects, on the basis of the predicted load amount, any one of the failover destination candidate nodes for each point of time at which a self node load amount is calculated so as to set it as a failover destination node. A cluster system, in which a plurality of information processing apparatuses are connected via a network so as to form a cluster, performs, when a fault occurs at a first information processing apparatus, a failover to a second information processing apparatus which is registered as a failover destination candidate node. |
