<P>PROBLEM TO BE SOLVED: To provide a multiprocessor system that can return from an uncorrectable fault in a directory to a continued active state. <P>SOLUTION: The multiprocessor system comprises a main memory 107, a plurality of processors 101, a memory controller 105 and the directory 106. The processors 101 have processor caches 102. The directory 106 stores entry information. The memory controller 105 ensures coherency between the processor caches, and if there is an anomaly in first entry information corresponding to first address information acquired from the directory 106, outputs a command to invalidate the first entry information to the processors 101. The processors 101 invalidate the first entry information in the processor caches 102, and output replies representing that the latest data designated by the first address information is in the main memory 107 to the memory controller 105. <P>COPYRIGHT: (C)2008,JPO&INPIT |
