A Comment on “A Necessary and Sufficient Condition for Deadlock-Free Adaptive Routing in Wormhole Networks”

Freek Verbeek, Julien Schmaltz

Open publisher page 19 citations

Abstract

The purpose of this comment is to show that Duato's condition for deadlock freedom is only sufficient and not necessary. We propose a fix to keep the condition necessary. The issue is subtle but essential: in a wormhole network worms necessarily do not intersect.
