<p><P>PROBLEM TO BE SOLVED: To shift, even when there exists even one thread whose load is high even in a CPU core, the CPU core having the thread to a power saving state. <P>SOLUTION: A power consumption reduction method includes: measuring the loads on threads that are running in a plurality of cores; checking the number of "high load threads" and the number of "low load threads" on the basis of the measuring results in order to check how many high load threads and low load threads exit in each of the cores; selecting, when there exists a core having high load threads whose number is less than a preset threshold on the number of high load threads, the core as a candidate core; and replacing the high load threads existing in the candidate core with the low load threads existing in other cores when the total number of the low load threads in a core other than the candidate core is not less than the number of the high load threads in the candidate core. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
