Fault tolerance issues in nanoelectronics
… effects are expected to impair their behaviour. Fault tolerant techniques will then be required. The aim of this thesis is to investigate the problem of transient errors in nanoelectronic devices. Transient error rates for a selection of nanoelectronic gates, based upon quantum cellular automata …

On fault tolerance of hardware samplers
… the robustness of hardware samplers to hardware faults. This study was motivated by our observation that several applications use sampling as a primitive and that sampling itself is an approximate method for computation. As such, it might be possible to lower energy consumption of hardware …

Generalized Consensus for Practical Fault-Tolerance
Despite extensive research on Byzantine Fault Tolerant (BFT) systems, overheads associated with such solutions preclude widespread adoption. Past efforts such as the Cross Fault Tolerance (XFT) model address this problem by making a weaker assumption that a majority of processes are correct and …

Fault tolerance in parallel data processing systems
… lead to a high failure probability. Existing fault tolerance strategies for parallel data processing systems usually handle faults with full restarts or work in a blocking manner. Either the systems do not consider faults at all, and restart the entire job if a fault occurs, or they save all …

A Fault Tolerance Protocol for Fast Recovery
… thesis presents research aimed at developing a fault tolerant protocol that is relevant in the context of parallel computing and provides fast restarts. We propose to combine the ideas of message logging and object based virtualization. We leverage the facts that message logging based protocols …

Exploration of fault tolerance in Apache Spark
… an exploration of two techniques for solving fault tolerance for batch processing in Apache Spark. We evaluate the benefits and challenges of these approaches. Apache Spark is a cluster computing system comprised of three main components: the driver program, the cluster manager, and the worker …

Defect and fault tolerance techniques for nano-electronics
… defect rates and high operation-time fault rates. This thesis is concerned with developing defect and fault tolerance techniques to address low manufacturing yield due to permanent defects and reduced computational reliability due to transient faults projected in nanoscale devices and …

Fault Tolerance Aspects of Virtual Massive MIMO Systems
… Givens Rotations is subjected to transient fault injection. The impact of faults in various parts of the implemented circuit on the detection performance is quantified. Most vulnerable components of the implemented circuit in terms of reliability are identified. Security is another major …

Physical Layer Fault Tolerance for Foundation Fieldbus Network
… this thesis a novel approach is proposed to add fault tolerance by achieving media redundancy on H1 networks. It presents an H1 topology framework capable of detecting and handling a break in the network to allow control and communication to continue uninterrupted. A test network with a …

Flexible Fault Tolerance for the Robot Operating System
… aspect of realizing an autonomous vehicle is a fault-tolerant design that can ensure the safe operation of the vehicle under unfavorable conditions.</p> <p>The goal of this thesis is to evaluate the feasibility of adding a dedicated fault tolerance module into a ROS based architecture. The fault …

Atomic Actions in Concurrent Systems (fault-Tolerance, Control)
The concept of an indivisible sequence of actions has been in use to design concurrent systems. An atomic action is an activity, possibly consisting of many steps performed by many processors, that appears primitive and indivisible to any activity outside the atomic action. The aim of the thesis is …

Coding approaches to fault tolerance in dynamic systems
A fault-tolerant system tolerates internal failures while preserving desirable overall behavior. Fault tolerance is necessary in life-critical or inaccessible applications, and also enables the design of reliable systems out of unreliable, less expensive components. This thesis discusses fault …

Scalable fault tolerance for high-performance streaming dataflow
… But websites must not go down, and current fault tolerance techniques for dataflow systems either come with long downtimes during recovery, or fail to scale to large deployments due to the overhead of global coordination. For example, in the failure of a single dataflow node, existing …

Bringing Fault Tolerance to Hardware Managers in PESNet
… to PESNet: utilization of the secondary ring for fault-tolerant communication, and dynamic reconfiguration of the network. Many ideas for supporting fault tolerance have been discussed in previous work and the hardware for PEBB-based systems was designed so support fault tolerance. However, in …
