Abstract
A multi-core processor system includes a core configured to detect that among cores different from a specific core executing a specific process, a given software different from specific software having a function equivalent to the specific process, is under execution; extract, from a database storing required computing capacities for the plural software and upon detecting that a given software is under execution, requirement values indicating the required computing capacity of the specific software and of the given software; judge for each the cores, whether a sum of the required computing capacities of the specific software and the software is at most a computing capacity value of the core; assign the specific software to a core for which the sum of the required computing capacities is judged to be at most the computing capacity value of the core; and suspend the specific core, upon assigning the specific software to the core.
