COMPUTER SYSTEM, CONTROL METHOD, RECORDING MEDIUM AND CONTROL PROGRAM

摘要

A computer system comprises both a directory storage section that stores directory information in respect of data stored in a memory (14) and a directory cache storage section (13) that stores a copy of the directory information stored in the directory storage section (15). A controller (12) makes the priority of storage in the directory cache storage section (13) of directory information in respect of data fetched in exclusive form higher than the priority of storage in the directory cache storage section (13) of directory information in respect of data fetched in shared form.
