An adaptive fault-tolerant routing algorithm for hypercube multicomputers

摘要

This paper presents a partially adaptive fault-tolerant routing algorithm for hypercube multicomputers. The algorithm is tolerant to n-1 link and/or node faults for an n-cube. It makes routing decisions adaptively based on local failure information only. It is simple to implement and needs a very small message overhead. A comparison between the algorithm and a popular previous work is given.
