5) the necessary conditions for deadlock 死锁的必要条件6) essential condition 必要条件 1. Several typys of alkali-aggregate reaction and its mechanism was introduced, then the essential conditions of the reaction were also pointed out. 本文介绍了混凝土的碱-骨料反应的危害,归纳了混凝土的碱-...
Circular wait condition A circular chain of threads requesting resources that are held by the next thread in the chain can exist. To prevent the possibility of deadlock from occurring, one of these conditions must not be allowed to exist. There are many different ways to prevent one or more ...
An important open problem in wormhole routing has been to find a necessary and sufficient condition for deadlock-free adaptive routing. Recently, Duato has... L Schwiebert,DN Jayasimha - 《Journal of Parallel & Distributed Computing》 被引量: 148发表: 1996年 A general theory for deadlock avoid...

Many deadlock control policies for flexible manufacturing systems (FMS) modelled by Petri nets are implemented via siphon control. Most of the existing methods design liveness-enforcing supervisors by adding control places for siphons based on their controllability conditions. To compute a liveness-...

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.Verbeek, Freek...
We present the first static necessary and sufficient condition for deadlock-free routing in wormhole networks. Our condition is much simpler and requires less assumptions than all previous ones. It is formally proven correct using an automated proof assistant. In particular, our condition applies to...
