The present invention prevents performance degradation due to memory latency in automatically allocating physical CPUs and memories to logical servers. Having information on arrangement of the physical CPUs and the memories, automatic allocation of physical CPUs to a logical server is implemented in consideration of reduction in memory latency. Moreover, the logical servers and the physicals CPU are grouped. Thereby, to each of the logical servers, a physical CPU in the same group as that of the logical server is allocated, and a memory under the memory controller to which the physical CPU belongs is allocated. In this way, the physical CPUs are allocated in consideration of reduction in memory latency.
