PROBLEM TO BE SOLVED: To provide an information processor capable of shortening communication time. SOLUTION: Communication registers 113e, 213e, 313e for storing information whether a communication area of a memory of each transmission destination node is free or not and memory storing address registers 113a to 113d, 213a to 213d, 313a to 313d are respectively included in respective channels 103, 203, 303 of respective nodes 100, 200, 300. Since the communication execution of each node can be started without inquiring its validity/invalidity, communication time can be shortened and communication can be simultaneously executed among plural nodes.
