Abstract

The ability to tolerate faults is critical in multi-computers employing large numbers of processors. This paper describes a class of fault-tolerant routing algorithms for n-dimensional meshes that can tolerate large numbers of faults without using virtual channels. We show that these routing algorithms prevent livelock and deadlock while remaining highly adaptive.
