The master calculates the communication time required for communication with the worker calculator on the basis of the information received and the elapsed time acquired. The master calculates the number of processings to be assigned to the worker calculator on the basis of the communication time calculated. The master generates a processing group to be assigned to the worker calculator on the basis of the number of processings calculated, and transmits the processing group generated to the worker calculator.
