An information processing device which has a plurality of process units for performing various kinds of processes includes a detecting unit that detects a processing loads of the process units; a determining unit that determines whether a total amount of the processing loads detected by the detecting unit is equal to or larger than a specific value; a designating unit that designates a process unit having a process state to be controlled, based on the processing loads of the process units detected by the detecting unit, when the determining unit determines that the total amount is equal to or larger than the specific value; a process identifying unit that identifies a process having an execution state to be controlled among processes being performed by the process unit designated by the designating unit; and a control unit that controls the execution state of the process identified by the process identifying unit.
