Characterization of Fault Recovery through Fault Injection on FTMP

Assessing Multi-Version Systems Through Fault Injection

Fault Detection in Autonomous Robots Endogenous fault detection through fault injection

In this dissertation, we study two new approaches to fault detection for autonomous robots. The rst approach involves the synthesis of software components that give a robot the capacity to detect faults which occur in itself. Our hypothesis is that hardware faults change the ow of sensory data and the actions performed by the control program. By detecting these changes, the presence of faults c...

Fault injection on GPGPU application

Today, with the development of GPU computing techniques in terms of architectures and hardware and software support, people realized that intensive computing workload could be ported to GPU device. Applications could exploit GPUs’ characteristics for parallel computing and gain a significantly high speedup comparing to CPU architecture. However, failures are still unavoidable. People have alrea...

Symbolic Fault Injection

Computer systems that are dependable in the presence of faults are increasingly in demand. Among available fault tolerance mechanisms, software-implemented hardware fault tolerance (SIHFT) is constantly gaining in popularity, because of its cost efficiency and flexibility. Fault tolerance mechanisms are often validated using fault injection, comprising a variety of techniques for introducing fa...

Improving Software Fault Injection

It has become well-established that software will never become bug-free, which has spurred research in mechanisms to contain faults and recover from them. Since such mechanisms deal with faults, fault injection is necessary to evaluate their effectiveness. However, little thought has been put into the question whether fault injection experiments faithfully represent the fault model designed by ...
