Issues on the Design of Efficient Fail-Safe Fault Tolerance

2009 20th International Symposium on Software Reliability Engineering, 2009
The design of a fault-tolerant program is known to be an inherentlydifficult task. Decisions taken during the designprocess will invariably have an impact on the efficiency of theresulting fault-tolerant program. In this paper, we focus on two suchdecisions, namely (i) the class of faults the program is to tolerate,and (ii) the variables that can be ...

System level policies for fault tolerance issues in the FERMI project

Proceedings of 1993 IEEE International Workshop on Defect and Fault Tolerance in VLSI Systems, 2002
The FERMI system, performing acquisition and DSP of calorimeter data in high energy collision experiments, planned at the LHC collider (CERN, Geneva, CH) is briefly overviewed. The system relies mainly upon the FERMI module, a dedicated VLSI multichip device performing most of the above functions, which is to be installed in large quantities (around 10/

Complexity Issues in Automated Synthesis of Failsafe Fault-Tolerance

IEEE Transactions on Dependable and Secure Computing, 2005
We focus on the problem of synthesizing failsafe fault-tolerance where fault-tolerance is added to an existing (fault-intolerant) program. A failsafe fault-tolerant program satisfies its specification (including safety and liveness) in the absence of faults. However, in the presence of faults, it satisfies its safety specification.

Reinitialization Issues in Fault Tolerant Systems

1983 American Control Conference, 1983
This paper is concerned with the reinitialization of fault tolerant systems in which detection and isolation (FDI) techniques are used, on-line, to identify and compensate for system failures. Specifically, we will focus on FDI techniques which utilize analytic redundancy, arising from a knowledge of the plant dynamics, by analyzing the residuals of a ...

Adaptive fault tolerance: issues and approaches

[1990] Proceedings. Second IEEE Workshop on Future Trends of Distributed Computing Systems, 2002
The purpose of adaptive fault tolerance (AFT) is to meet the dynamically and widely changing fault tolerance requirement by efficiently and adaptively utilizing a limited and dynamically changing amount of available redundant processing resources. The authors attempt to establish the notion of AFT in a reasonably concrete form, identify major technical

On issues in fault-tolerant computer design

Computers & Electrical Engineering, 1981
Abstract Fault-tolerant computer systems tend to be unique creations based on practical experience. Any new designer will probably be baffled by the diversity of the concepts and designs which can be found in literature and/or in practice since criteria for selecting an approach have not been clearly established.

Rating issues in fault tolerant PMSM

2009 IEEE International Electric Machines and Drives Conference, 2009
The necessary reliability of a safety critical drive system is often partly achieved by using fault tolerant electrical machines. Although there are various degrees as to what types of faults and to the duration the machine has to tolerate, these generally include open and short circuit winding faults.

Performance issues in C language fault-tolerant software

Computer Languages, 1989
Abstract An experiment is described for the determination of the overhead associated with N-version programming, a technique for achieving software reliability. Results are presented for the performance as a function of the number of versions in the voting process.
