Abstract:
1. A computer cluster for use as one of a plurality of components which are arranged at a plurality of lattice points in an interconnection network having a lattice-like structure, the interconnection network transmitting packets between the plurality of the lattice points, the computer cluster comprising: first and third nodes each of which is connected to first and third components among the plurality of components, the first and third components including a plurality of nodes, the first and third components being located adjacent to the computer cluster along a direction parallel to a first axis; second and fourth nodes each of which is connected to second and fourth components among the plurality of components, the second and fourth components including a plurality of nodes, the second and fourth components being located adjacent to the computer cluster along a direction parallel to a second axis; and an internal communication network to interconnect the first, second, third and fourth nodes; wherein each of the first and third nodes is connected to the first and third components via routes bypassing the internal communication network, and each of the second and fourth nodes is connected to the second and fourth components via routes bypassing the internal communication network, each of the first and third nodes is connected to neither the second component nor the fourth component, and each of the second and fourth nodes is connected to neither the first component nor the third component, the first and third nodes, when receiving a packet to be transmitted to one of the second and fourth components, transfer the received packet to the second node or the fourth node through the internal communication network, and the second and fourth nodes, when receiving a packet to be transmitted to one of the first and third components, transfer the received packet to the first node or the third node through the internal communication network.
