A computer system includes a main memory for storing a large amount of data, a cache memory that can be accessed at a higher speed than the main memory, a memory replacement controller for controlling the replacement of data between the main memory and the cache memory, and a memory controller capable of allocating one or more divided portions of the cache memory to each process unit. The memory replacement controller stores priority information for each process unit, and replaces lines of the cache memory based on a replacement algorithm taking the priority information into consideration, wherein the divided portions of the cache memory are allocated so that the storage area is partially shared between process units, after which the allocated amounts of cache memory are changed automatically.
