An information processing system has a plurality of nodes which use a snoop cache memory in each of the plurality of nodes. A directory, which maintains a cache coherence of the snoop cache memory of the plurality of nodes, has a first directory and a second directory which has a different format from a format of the first directory and is only used for a shared state. The node searches the first and second directories, and determines the other node to transmit a snoop.
