摘要
A control unit stores data used in a process to a shared cache memory. The control unit provides a shared queue in a memory space of the shared cache memory and performs LRU control with the use of the shared queue. The control unit also provides a local queue in the memory space of the shared cache memory. The control unit enqueues a CBE (management information) for a cache page used by a core in a process to the local queue. The control unit dequeues a plurality of CBEs from the local queue upon satisfaction of a predetermined condition, and enqueues the dequeued CBEs to the shared queue.
