Input information including processor group division information that is used to divide processors, which will be used in parallel calculation, into groups each of which will form a rectangular shape on a network and that is specified by information other than logical processor numbers is input to the processors of a parallel computer system. Each processor checks the received processor group division information to determine the logical processor numbers belonging to the groups. Communication among the determined possessors is done in a plurality of stages: intra-group communication processing and inter-group communication processing. Because the processors forming a group are arranged in a rectangular shape on the network, intra-group communication processing may be executed with no network conflict.
