A Comment onA Necessary and Sufficient Condition for Deadlock-Free Adaptive Routing in Wormhole Networks
2011 Edition, Volume 22, October 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

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...

A necessary and sufficient condition for deadlock-free adaptive routing in wormhole networks
1995 Edition, Volume 6, October 1, 1995 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Deadlock avoidance is a key issue in wormhole networks. A first approach by W.J. Dally and C.L. Seitz (1987) consists of removing the cyclic dependencies between channels. Many deterministic and adaptive routing algorithms have...

A Necessary and Sufficient Condition for Deadlock-Free Adaptive Routing in Wormhole Networks
1994 Edition, Volume 1, August 1, 1994 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Deadlock avoidance is a key issue in wormhole networks. A first approach [8] consists of removing the cyclic dependencies between channels. Although this is a necessary and sufficient condition for...

A new theory of deadlock-free adaptive routing in wormhole networks
1993 Edition, Volume 4, December 1, 1993 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The theoretical background for the design of deadlock-free adaptive routing algorithms for wormhole networks is developed. The author proposes some basic definitions and two theorems. These create the conditions to verify that an...

A theory of deadlock-free adaptive multicast routing in wormhole networks
1995 Edition, Volume 6, September 1, 1995 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A theory for the design of deadlock-free adaptive routing algorithms for wormhole networks, proposed by the author (1991, 1993), supplies sufficient conditions for an adaptive routing algorithm to be...

A new theory of deadlock-free adaptive multicast routing in wormhole networks
1993 Edition, January 1, 1993 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A theory for the design of deadlock-free adaptive routing algorithms for wormhole networks has been proposed previously. This theory supplies the sufficient conditions for an adaptive routing algorithm to be...

Comments on "A necessary and sufficient condition for the stability of nonnegative interval discrete systems" by B. Shafai et al
1992 Edition, Volume 37, November 1, 1992 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

It is shown that a necessary and sufficient condition for the stability of nonnegative interval discrete systems reported in the above-named work (ibid., vol.36, no.6, p.742-6, June 1991) can be alternatively be established by using a previous...

Comments on "A necessary and sufficient condition for the stability of nonnegative interval discrete systems" by B. Shafai et al
1993 Edition, Volume 38, January 1, 1993 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In the above-titled paper (ibid., vol.36, no.6, p.742-6, June 1991), the authors gave necessary and sufficient conditions for the Schur stability of nonnegative interval matrices. The commenter suggests that these conditions may be more conveniently stated...
