ABSTRACT:
An information processing apparatus provides control of power consumption of multiple central processors. The apparatus includes, sections for: measuring temperature of each central processor; calculating halt percentage for each of the central processors from measured temperatures halt percentages and a particular thread executed in each of the central processors; transitioning to a wait state in which a central processor executes another thread during a predetermined wait period or a running state in which an internal halt instruction is executed causing the central processor to halt processing in accordance with the halt percentage; and interrupting each of the central processors and causing a central processor that is halting processing to resume processing.
