The complex interactions between faults, errors, failures and fault handling mechanisms can be studied via injection experiments. This paper presents an investigation of both fault and error injection techniques for emulating software faults. For evaluation, 1600 software faults and 5400 time-triggered errors were injected into an embedded real-time system. The cost-related results are: (i) the...

Full chip statistical fault injection has been performed on a hardware emulated POWER6 platform. These results were validated against proton beam injection results. The fault isolation, error recovery and error logging capabilities of the POWER6 enabled measurement of the architectural derating factors. The proportion of errors as well as derating factors matched well between the simulated and ...

It is well known that workload has significant impact on dependability measures obtained from fault injection experiments [3][5]. The effects on the outcome of fault injection experiments when the input data to be processed by the workload is altered, should also be considered [2]. To investigate the effects of workload input domain on fault injection results (e.g. error coverage), an experimen...

The Pseudo Fisher Linear Discriminant (PFLD) based on a pseudo-inverse technique shows a peaking behaviour of the generalization error for training sample sizes that are about the feature size: with an increase in the training sample size the generalization error at first decreases reaching the minimum, then increases reaching the maximum at the point where the training sample size is equal to ...

Developing software for mobile platforms we face the problem of dealing with various erroneous situations, transient faults, component incompatibilities which influence their operations. This results in the need of embedding error detection mechanisms and handling them software procedures. This problem has been appreciated by Samsung. As the consequence of this need we have developed a special ...

Reliability of the current microprocessor technology is seriously challenged by radiation-induced soft errors. Accurate Vulnerability Factor (VF) modeling of system components is crucial in designing costeffective protection schemes in high-performance processors. Although Statistical Fault Injection (SFI) techniques can be used to provide relatively accurate VF estimations, they are often very...

This thesis deals with the problem of validating and estimating the effectiveness of error handling mechanisms in computer systems. The main contribution is an assessment of the effectiveness and usefulness of several physical fault injection techniques. The assessment is based on fault injection experiments conducted on the fault-tolerant, distributed, real-time system MARS and the Thor microp...

In this paper, we present a novel fault injection framework for system call invocation errors, called Phoebe. Phoebe is unique as follows. First, enables developers to have full observability of invocations. Second, generates error models that are realistic in the sense they mimic errors naturally happen production. Third, able automatically conduct experiments systematically assess reliability...
