MULTI-CORE PROCESSOR SYSTEM, METHOD OF POWER CONTROL, AND POWER CONTROL PROGRAM

摘要

When software to be migrated is an OS, a CPU (#0) and a CPU (#2) migrate specific software from the CPU (#0) to the CPU (#2) using a migrating unit (304) executed by a hypervisor (204). The CPU (#2) detects a state of migration of the specific software from the CPU (#0) to the CPU (#2) whose maximal processing capacity value is lower than that of the CPU (#0) using a detecting unit (302). After the detection, when the detecting unit (302) detects a state of migration, the CPU (#2) sets a processing capacity value of the CPU (#0) at the time of the detection to be a processing capacity value that is lower than that before the migration suing a setting unit (303).
