In this paper, we present adaptive fault-tolerant deadlock-free r outing algorithms for hypercubes and meshes by using only 3 virtual channels and 2 virtual channels respectively. Based on the concept of unsafe nodes, we design a routing algorithm for hypercubes that can tolerate at least n , 1 node faults and can route a message via a path of length no more than the Hamming distance b etween the source and destination plus four. We also develop a routing algorithm for meshes that can tolerate
more » ... ny block faults, as long as the distance b etween any two nodes in di erent faulty blocks is at least 2 in each dimension.
