The invention achieves optimization of partition division by implementing resource distribution with a characteristic of a system into consideration so that the processing performance of the entire system is enhanced. To this end, a system management section in the invention calculates an optimum distribution of a plurality of resources to partitions based on distance information regarding the distance between a plurality of resources and data movement frequencies between the plural resources. The plural resources are distributed to the plural partitions through a plurality of partition management sections so that the optimum distribution state may be established.
