PROBLEM TO BE SOLVED: To enable each node to receive services without using too much resources for providing services and each node can receive services as long as its own node keeps functioning properly in a computer system composed of plural nodes. SOLUTION: Shared processes 108-1 to 108-n for providing services on a shared memory 102 accessible from each node 101-1 to 101-4, and a shared process control table 107 which includes a control structural body and a node plug for each of the shared processes 108-1 to 108-n are arranged. If shared process dispatchers 105-1 to 105-4 judge that the shared processes are occupied by other nodes on the basis of a node flag in the shared process control table 107 when a service request regarding the shared processes 108-1 to 108-n is issued from APs 103-1 to 103-4, the service request is made to wait, and if it is judged that they are not occupied, the shared process is made to process the service request. |
