PROBLEM TO BE SOLVED: To attain an efficient multi-cast while suppressing the capacity of a storing mechanism for recording the destination of a multi-cast for access information necessary for the attainment of a distributed/shared memory. SOLUTION: When the delivery information of cache maintenance information is not stored in a directory in a computer system connecting plural nodes to be communicated with each other, information is broadcasted to all nodes (S11 to S14, S20). The delivery information is recorded in the directory based upon an information delivery result by the broadcast (S17, S18). When the delivery information is stored in the directory, the information is delivered (multi-casted) to a node specified by the delivery information (S14 to S16). The delivery information stored in the directory is updated based upon the multi-cast result (S17, S18). |
