Abstract(in English) | Since a parallel computer and Network-on-Chip (NoC) have many elements, their failure rate is high. Fault-tolerance is important for such systems, which sometimes have partial failure, to avoid system-down. Wormhole Switching is widely used switching and is weak to failure; and therefore, many fault-tolerant routing algorithm for Wormhole Switching have been proposed. Some conventional routing algorithm achieve low throughput because they have severe restriction to determine available nodes. This paper proposed fault-tolerant Wormhole Switching which has back-tracking capability and is suitable for flexible routing algorithm. Back-tracking is enabled by a copy of header flit, which investigates the network in advance. That is, back-tracking to the node where the copy header flit was generated is possible. Computer simulation says that for the network with 30 to 40% failure links, the throughput of the proposed method is higher than that of the conventional method. |
