摘要： A parallel computer includes a plurality of nodes. Each of the nodes includes a router directly or indirectly connected to each of the other nodes and a network interface connected to an external network of the parallel computer. The network interface includes a storage unit that holds detour route information indicating a detour route corresponding to a communication route from a node in which the network interface is included to another node. The network interface further includes a reception processing unit that, when the network interface receives data destined to one node of the parallel computer from the external network, sets detour route information corresponding to a communication route from the node in which the network interface is included to the destination node of the data for the data and transmits the data for which the detour route information is set to the destination node.
