Automating the Addition of Fail-Safe Fault-Tolerance: Beyond Fusion-Closed Specifications [chapter]

Felix C. Gärtner, Arshad Jhumka
2004 Lecture Notes in Computer Science  
Hence, automated methods that add fault tolerance can now be efficiently applied in environments where specifications are not necessarily fusion closed.  ...  However, addition of history variables causes an exponential growth of the state space of the program, causing addition of fault tolerance to be expensive.  ...  Work by the first author was supported by Deutsche Forschungsgemeinschaft (DFG) as part of "Graduiertenkolleg ISIA" and Emmy Noether programme.  ...

ADDING FAULT-TOLERANCE TO STATE MACHINE-BASED DESIGNS [chapter]

SANDEEP S. KULKARNI, ANISH ARORA, ALI EBNENASIR
2007 Software Engineering of Fault Tolerant Systems  
Specifically, we present sound and complete deterministic algorithms for automated addition of (failsafe/nonmasking/masking) fault-tolerance to the functional design of concurrent programs.  ...  We also discuss (1) the effect of distribution and safety specification model on the complexity of adding fault-tolerance, and (2) the impact of the proposed algorithms on the addition of multitolerance  ...  Since the specification is suffix-closed and fusion-closed, it is possible to specify a safety specification as a set of bad transitions.  ...

Effective fusion and separation of distribution, fault-tolerance, and energy-efficiency concerns

Young-Woo Kwon
2013 Proceedings of the 2013 companion publication for conference on Systems, programming, & applications: software for humanity - SPLASH '13  
Thus, software developers should be able to simultaneously reason about and handle the concerns of distribution, fault-tolerance, and energy-efficiency.  ...  Being closely intertwined, these concerns can introduce significant complexity into the design and implementation of modern software.  ...  They have argued that enhancing a fault-tolerant system with a set of fault-tolerant components will lead to a fault-tolerant system.  ...

Robustness Issues in Fault Diagnosis and Fault Tolerant Control

Jakob Stoustrup, Kemin Zhou
2008 Journal of Control Science and Engineering  
Wu et al. addresses fault tolerant control of a distributed database system. The fault tolerant design relies on data redundancy in the partitioned system architecture.  ...  Many techniques have been developed for fault detection and fault tolerant control. However, the issue of robustness of fault detection and fault tolerant control has not been sufficiently addressed.  ...  ACKNOWLEDGMENTS The authors would like to thank the anonymous reviewers for their constructive comments and suggestions that have improved the quality of the manuscript.  ...

The complexity of adding failsafe fault-tolerance

S.S. Kulkarni, A. Ebnenasir
Proceedings 22nd International Conference on Distributed Computing Systems  
In this paper, we focus our attention on the problem of automating the addition of failsafe fault-tolerance where fault-tolerance is added to an existing (fault-intolerant) program.  ...  addition of failsafe fault-tolerance is still NP-hard.  ...  Thus, given an algorithm that automates the addition of failsafe fault-tolerance, we can automate one step of designing masking fault-tolerance.  ...

Enhancing the fault-tolerance of nonmasking programs

S.S. Kulkarni, A. Ebnenasir
23rd International Conference on Distributed Computing Systems, 2003. Proceedings.  
In this paper, we focus on automated techniques to enhance the fault-tolerance of a nonmasking fault-tolerant program to masking.  ...  Hence, these algorithms can partially reap the benefits of automation when the cost of adding masking fault-tolerance to a fault-intolerant program is high.  ...  For a suffix closed and fusion closed specification, the safety specification can be specified [7] as a set of bad transitions, that is, for program , its safety specification is a subset of g a % !  ...
