Fiesta++ : a software implemented fault injection tool for transient fault injection
… can cause systems to malfunction or even crash. Fault injection is a technique used for simulating the effect of such errors on the system. Fault injection tools inject errors in either the software running on the processors or in the underlying computer hardware to simulate the effect of a fault …

Developing a multi-level fault injection environment
Dependability and fault tolerance are important aspects of modern computer systems. Particle strikes or electromagnetic interference can cause internal state of the system to change, which might cause errors to the system with non-negligible probability. Such errors are termed "soft errors". Bit …

Automated Fault-Injection-Based Dependability Analysis of Distributed Computer Systems
NFTAPE is different from other fault-injection tools in that it separates the components that inject faults or trigger faults (called Lightweight Fault Injectors or Lightweight Triggers) from the rest of the tool. Though this is a simple change, it substantially improves our ability to analyze …

Analysis of the impact of sequencing errors on BLAST using fault injection
… the quantification of the impact using fault injection. Faults were injected in the input sequence data, and the analyses were run. Change in the output of the analyses was interpreted as the impact of faults, or errors. Three commonly used algorithms were used: BLAST, SSEARCH, and …
