Abstract
In a parallel processor system, a plurality of nodes each comprising a processor and a main storage unit are interconnected through a network, wherein a user process is executed under the control of an operating system in each of the nodes and inter-process communications are performed through the network for transmitting and receiving messages among the nodes. Reception buffers are provided in a main storage unit and addressed by pool pages, which are discontinuous in a logical address domain or in a real address domain, in a virtual space used by the user process executed by each node. Additionally, reception buffer control information is located on the main storage unit for managing the reception buffers. A node, when receiving a message, uses communication information included in the received message and reception buffer control information to calculate a real address in the reception buffers for storing the received message.
