Non-Uniform Fault Tolerance
نویسندگان
چکیده
As devices become more susceptible to transient faults that can affect program correctness, processor designers will increasingly compensate by adding hardware or software redundancy. Proposed redundancy techniques and those currently in use are generally applied uniformly to a structure despite non-uniformity in the way errors within the structure manifest themselves in programs. This uniform protection leads to inefficiency in terms of performance, power, and area. Using case studies involving the register file, this paper motivates an alternative Non-Uniform Fault Tolerance approach which improves reliability over uniform approaches by spending the redundancy budget on those areas most susceptible.

A generalized ABFT technique using a fault tolerant neural network
In this paper we first show that standard BP algorithm cannot yeild to a uniform information distribution over the neural network architecture. A measure of sensitivity is defined to evaluate fault tolerance of neural network and then we show that the sensitivity of a link is closely related to the amount of information passes through it. Based on this assumption, we prove that the distribu...
متن کاملConnecting Supply and Demand Vertices with Fault Tolerance
Fault tolerance can improve reliability and robustness when providing connectivity among entities. Many studies had accounted for entities that were uniform and similar in nature. However, applications today often require the entities to have distinguished roles. For instance, a power system has two types of entities: sources and loads. A source mainly concerns no disconnection from the network...

We study the e ects of random faults on the behavior of one-dimensional, non-uniform cellular automata (CA), where the local update rule need not be identical for all grid sites. The CA systems examined were obtained via an approach known as cellular programming, which involves the evolution of non-uniform CAs to perform non-trivial computational tasks. Using the \system replicas" methodology, ...

Abstract Using mobile agents, it is possible to bring the code close to the resources, which is not foreseen by the traditional client/server paradigm. Compared to the client/server computing paradigm, the greater flexibility of the mobile agent paradigm comes at additional costs as well as the additional complexity of developing and managing mobile agent-based applications. Such complexity ...
