Abstract:
1. An information processing apparatus comprising: a crossbar switch; a plurality of crossbar interfaces having ports coupled to the crossbar switch, wherein each of the plurality of crossbar interfaces belongs to one of a plurality of groups; a bypass route directly and exclusively coupling a first crossbar interface and a second crossbar interface that belong to a single group in which a frequency of use of the ports is greater than or equal to a predetermined value amongst the plurality of crossbar interfaces; and a plurality of computing nodes coupled to the crossbar switch via the plurality of crossbar interfaces, wherein the plurality of computing nodes include a first computing node configured to perform a first computation and to transmit a packet, the first crossbar interface is coupled to the first computing node and is configured to transfer the packet transmitted from the first computing node, the crossbar switch is configured to receive the packet from the first computing node and to switch a communication channel of the packet, the second crossbar interface is coupled between the crossbar switch and the first crossbar interface, and is configured to transfer the packet from the crossbar switch or the first crossbar interface, the plurality of computing nodes include a second computing node configured to receive the packet from the second crossbar interface coupled thereto and to perform a second computation, the first crossbar interface and the second crossbar interface belong to the single group and are directly coupled by the bypass route, the ports of the first crossbar interface and the ports of the second crossbar interface are respectively coupled directly to the crossbar switch, and the second crossbar interface simultaneously receives the packet from the crossbar switch and the packet from the first crossbar interface.
