A first computer system including a first computer and a first display device is provided. The first computer includes a processor. The first display device is connected to the first computer and displays a graphics signal. The processor receives at least one of system state information and power state information from a second computer system including a second computer and a second display device, and generates a first power saving control command on the basis of the received state information. The processor transmits the first power saving control command to the second computer system. The first power saving control command is a command for controlling power saving of at least one of the second computer and the second display device.

Provided is a method of dynamically controlling power in a multicore environment including a multicore processor which includes a plurality of cores and a scheduler. The method includes determining whether a management policy is set, collecting frequency change information used to change frequencies of the plurality of cores when it is determined that the management policy is set, calculating an average load of each core on a basis of the frequency change information, calculating an average frequency of each core according to the calculated average load of each core, comparing the average frequency of each core and a predetermined threshold value, and setting a next frequency of each core according to the comparison result.
