Formal Analysis of a Fault-Tolerant Routing Algorithm for a Network-on-Chip [chapter]

Zhen Zhang, Wendelin Serwe, Jian Wu, Tomohiro Yoneda, Hao Zheng, Chris Myers
2014 Lecture Notes in Computer Science  
A fault-tolerant routing algorithm in Network-on-Chip architectures provides adaptivity for on-chip communications.  ...  Adding faulttolerance adaptivity to a routing algorithm increases its design complexity and makes it prone to deadlock and other problems if improperly implemented.  ...  To guarantee deadlock freedom, the routing algorithm disallows certain turns in the network.  ...

Survey of protocol definition and verification techniques

Carl A. Sunshine
1978 Computer Networks (1976)  
Techniques for definition and verification of computer network protocols have progressed significantly in the past two years to the point where complex real world protocols such as HDLC, X.25, and Cyclades  ...  This success is largely due to the combination of two apparently divergent approaches-state transitions, and assertion proofs-and to the greater automation of the verification process.  ...  Danthine [7] generates all paths (if any) leading to potential deadlock states.  ...

The FC2TOOLS set [chapter]

Amar Bouali, Annie Ressouche, Valérie Roy, Robert Simone
1996 Lecture Notes in Computer Science  
We are currently extending these features of FC2IMPLICIT SO that labeled predicates on states, hiding of behaviours irrelevant to specific analysis, and use of side observer automata would allow to check  ...  In addition FC2IMPLICIT has a fast checker for deadlocks, IiveIock or divergent states, for which it produces counterexample paths in case of existence, while FC2EXPLICIT allows compositional reduction  ...  We use symbolic methods based on BDDs for an easy evaluation of global state spaces and deadlock checking.  ...

Automatic generation of deadlock detection algorithms for a family of microarchitecture description languages of communication fabrics

Freek Verbeek, Julien Schmaltz
2012 2012 IEEE International High Level Design Validation and Test Workshop (HLDVT)  
Our main contribution is to automatically generate an efficient deadlock detection algorithm tailored to a given set of primitives.  ...  We prove that the automatically generated algorithms are correct by construction, i.e., they correctly detect deadlocks in all fabrics defined in the language for which they are generated.  ...  The algorithm searches for a state with a dead channel. It overapproximates the set of reachable states, i.e., it might find a deadlock state that is not reachable from an empty network.  ...

Some Complexity Results in the Design of Deadlock-Free Packet Switching Networks

Sam Toueg, Kenneth Steiglitz
1981 SIAM journal on computing (Print)  
Deadlock states have been observed in existing packet switching networks [KL]; they tend to occur under near-saturation input load [GHKP].  ...  It is not hard to see that the network is deadlocked.  ...  It is easy to check that the network is in a deadlock state. Suppose now that the network has a deadlock state. Then there is at least one cycle of deadlocked packets in this state.  ...

Formal Verification of a Programmable Hypersurface [chapter]

Panagiotis Kouvaros, Dimitrios Kouzapas, Anna Philippou, Julius Georgiou, Loukas Petrou, Andreas Pitsillides
2018 Lecture Notes in Computer Science  
This paper shares the experience of a rigorous design procedure for the Hypersurface network, that involves iterations between designing a network and its protocols and the formal evaluation of each design  ...  The Hypersurface design is concerned with the development of a network of switch controllers that are responsible for configuring the metamaterial.  ...  Furthermore, also relating to the state-space explosion problem is the fact that we have to limit our analysis for specific configuration sequences, though in principle it would be useful to check algorithm  ...

Distributed Deadlock Detection in Mobile Agent Systems [chapter]

Bruce Ashfield, Dwight Deugo, Franz Oppacher, Tony White
2002 Lecture Notes in Computer Science  
Existing solutions to distributed computing problems, such as deadlock avoidance algorithms, are not suited to environments where both clients and servers move freely through the network.  ...  This paper describes a distributed deadlock solution for use in mobile agent systems.  ...  For example, the distributed deadlock detection algorithm described by [5] states "The above algorithm should find any deadlock that occurs, provided that waiting transactions do no abort and there are  ...

Ant Colony Optimization for Deadlock Detection in Concurrent Systems

Gianpiero Francesca, Antonella Santone, Gigliola Vaglini, Maria Luisa Villani
2011 2011 IEEE 35th Annual Computer Software and Applications Conference  
The biggest challenge toward the development of effective deadlock detection schemes remains the state-space explosion problem when model checking is used for proving the correctness of a system with respect  ...  In this paper we propose the use of the Ant Colony Optimization (ACO) to reduce the state explosion problem arising when finding deadlocks in complex networks described using Calculus of Communicating  ...  For this reason, they can be suitable for searching states (in particular deadlocks) in the graph of large system models, for which traditional exploration algorithms fail.  ...
