MULTI-CORE PROCESSOR SYSTEM, THREAD CONTROL METHOD, AND COMPUTER PRODUCT

摘要

A multi-core processor system includes a first core configured to detect a state where a first thread that is allocated to a first core and a second thread that is allocated to a second core access a common resource; calculate, upon detecting the state and based on a first cycle for the first thread to be allocated to the first core and a second cycle for the second thread to be allocated to the second core, a contention cycle for the first and the second threads to cause access contention for the resource; and select a thread allocated at a time before or after the contention cycle of a core to which a given thread that is either the first or the second thread is allocated at the contention cycle; and a second core configured to switch the times at which the given thread and the selected thread are allocated.
