摘要：
Load distribution among multiple cores is achieved without altering an execution object for single core. A CPU (#0) detects, by a detecting unit (303), an assignment to a CPU (#1), of a child thread (302) that is generated from a parent thread (301) assigned to a CPU (#2). After the detection, the CPU (#0) determines whether the parent thread (301) and the child thread (302) operate exclusively of each other. If the parent thread (301) and the child thread (302) operate exclusively, the CPU (#0) copies copy-source data stored in a parent thread context area (311) onto a copied-parent thread context area (312). After the copying, the CPU (#0) calculates an offset value for an address of copy-destination data based on the destination address of the copied data and a predetermined value. After the calculation, the CPU (#0) notifies the CPU (#1) of the offset value for the destination address of the copied data by a notifying unit (307).
