摘要

我们提出了一种自适应和无死锁的路由算法，以容忍不规则的故障模式，每个物理链路使用两个虚拟通道。它可以将节点利用率提高到100%。当节点发生故障或恢复时，中央控制单元构建一个有向路径图，用于生成消息路径的中间节点。因此，消息可以通过一组“中间节点”在故障块中从源发送到目的地。如果中央控制单元不可用，我们的方法需要全局故障信息。

Adaptive and fault-tolerant routing with 100% node utilization for mesh multicomputer

We propose an adaptive and deadlock-free routing algorithm to tolerate irregular faulty patterns using two virtual channels per physical link. It can improve the node utilization up to 100%. When a node becomes faulty or recovered, the central control unit constructs a directed path graph which is used for generating the intermediate nodes of the message path. Thus a message can be transmitted from sources or to destinations within faulty blocks via a set of "intermediate nodes". Our method requires the global failure information if the central control unit is not available.
