Abstract: A management unit causes a plurality of processing units to execute a calculation process. A determining unit determines whether a communication time for a communication process of exchanging a calculation result obtained from the calculation process is longer than a calculation time for the calculation process, the communication process being executed between a first computational node including the processor and a second computational node being a different computational node from the first computational node. A control unit limits number of processing units when the determining unit has determined that the communication time is longer than the calculation time.
