TLDR
In this article, a deadlock-free routing algorithm for arbitrary interconnection networks using the concept of virtual channels is presented, where the necessary and sufficient condition for deadlock free routing is the absence of cycles in a channel dependency graph.Abstract:
A deadlock-free routing algorithm can be generated for arbitrary interconnection networks using the concept of virtual channels. A necessary and sufficient condition for deadlock-free routing is the absence of cycles in a channel dependency graph. Given an arbitrary network and a routing function, the cycles of the channel dependency graph can be removed by splitting physical channels into groups of virtual channels. This method is used to develop deadlock-free routing algorithms for k-ary n-cubes, for cube-connected cycles, and for shuffle-exchange networks.read more
