Optimal Scheduling for Fault-Tolerant and Firm Real-Time Systems
Time redundancy is an effective method for achieving fault tolerance in a real-time system, when space redundancy cannot be used for cost or weight constraints. This paper presents a fault-tolerant scheduling algorithm for real-time systems consisting of firm and hard periodic tasks. Firm tasks can occasionally skip one instance according to a predefined quality-ofservice parameter, whereas har...
متن کاملOptimal Discrete Controller Synthesis for Modeling Fault-tolerant Distributed Systems
We propose a safe design method for safe execution systems, based on faulttolerance techniques: it uses optimal discrete controller synthesis (DCS) to generate a correct-by-construction fault-tolerant system. The properties enforced concern consistent execution, functionality fulfillment (whatever the faults, under some failure hypothesis), and several optimizations (of the tasks’ execution tim...
متن کاملFault-tolerant training for optimal interpolative nets
The optimal interpolative (OI) classification network is extended to include fault tolerance and make the network more robust to the loss of a neuron. The OI net has the characteristic that the training data are fit with no more neurons than necessary. Fault tolerance further reduces the number of neurons generated during the learning procedure while maintaining the generalization capabilities ...
متن کاملFault-tolerant Distributed Systems
Distributed systems have two key advantages: they increase the quality of our interaction with computers and the quantity of resources available to us. The quality increases as components of a distributed system hide failures from users and render a service more reliable (safer from loss) andmore available (less downtime). Increases in quantity, such as computational power and storage capacity,...
متن کاملFault-Tolerant Dynamic Systems
Modular redundancy (system replication) and other traditional techniques for fault tolerance in dynamic systems are expensive, and rely heavily — particularly in the case of systems operating over extended time horizons — on the assumption that the error-correcting mechanism (e.g., voting) is fault-free. Herein, we construct redundant dynamic systems in a way that achieves tolerance to transien...
