Abstract
A multi-core processor system includes a multi-core processor that has plural core groups; and a storage device that stores a constraint on execution time for each application. A first identified core of the multi-core processor is configured to identify a constraint on execution time of a given application that is among the applications and for which an invocation instruction is received; determine whether the identified constraint meets a performance drop condition; assign the given application to a predetermined core of the multi-core processor, upon determining that the identified constraint meets the performance drop condition; and notify a second identified core of a core group among the core groups, of an assignment instruction for the given application, upon determining that the identified constraint does not meet the performance drop condition.
