<p>PROBLEM TO BE SOLVED: To set memory management overhead to be a minimum and to effectively use a memory. SOLUTION: In parallel processors, plural nodes ND0 -NDn constituted by instruction processors IP0 -IPn and main storages MS0 -MSn are connected by a network. In the respective nodes ND0 -NDn , processes are executed under the control of an operating system, and the nodes ND0 -NDn execute inter-process communication through the network so as to receive messages. Reception buffers reside in the main storages MS0 -MSn and they are constituted by pool pages which are not continuous in terms of logical address or real address on a virtual space which the processes executed in the nodes ND0 -NDn use. Reception buffer control information is arranged on the main storages MS0 -MSn and they manage the reception buffers. The nodes ND0 -NDn receiving the messages obtain the real addresses on reception buffer pools receiving the messages by using communication control information included in the received messages and reception buffer control information.</p> |
