We present a peer logging system for reducing performance overhead in fault-tolerant distributed shared memory systems. Our system provides fault-tolerant shared memory using individual checkpointing and rollback. Peer logging logs DSM modification messages to remote nodes instead of to local disks. We present results for implementations of our fault-tolerant technique using simulations of both...

AI-based search techniques have been adapted as viable, topology-independent fault-tolerant routing strategies on multiprocessor networks [P.K.K. Loh, Artificial intelligence search techniques as fault-tolerant routing strategies, Parallel Computing 22 (8) (1996) 1127–1147]. These fault-tolerant routing strategies are viable with the exception that the routes obtained were non-minimal. This mea...

This paper reports on the results of our recent NASA SBIR contract, “Autonomous Self-Repairing Circuits,” in which we developed a novel approach to fault-tolerant circuit synthesis utilizing a selfconfigurable hardware platform. The approach was based on the use of atomic components called Supercells. These Supercells perform several functions in the building of a desired target circuit: fault ...

When a fault occurs in a system, the main problem to be addressed is to raise an alarm, ideally diagnose what fault has occurred, and then decide how to deal with it. The problem of detecting a fault, finding the source/location and then taking appropriate action is the basis of fault tolerant control. In this chapter, an introduction to fault tolerant control (FTC) and fault detection and isol...

This paper studies on a fuzzy predictive model based high speed train fault tolerant control method, which is very important for high speed train’s high-precision control. After analyzing related research works about fault tolerant control and the development of modern high speed train, design of the high speed train fault tolerant control system is given. Afterwards, the high speed train fault...

High performance computing platforms such as Clusters, Grid and Desktop Grids are becoming larger and subject to more frequent failures. MPI is one of the most used message passing libraries in HPC applications. These two trends raise the need for fault-tolerant MPI. The MPICH-V project focuses on designing, implementing and comparing several automatic fault-tolerant protocols for MPI applicati...

SRAM based FPGAs are attracting considerable interest especially in aerospace applications due to their high reconfigurability, low cost and availability. However, these devices are strongly susceptible to space radiation effects which are able to cause unwanted single event upsets (SEUs) in the configuration memory. In order to mitigate the SEU effects, various methods have been investigated i...

Process groups are a common abstraction for fault-tolerant computing in distributed systems. We present a security architecture that extends.Abstract Concerns about both security and fault-tolerance have had an important. Tion of fault tolerance will face some of the same problems, and benefit from. The security testing prototype is.A Secure and Fault-tolerant framework for Mobile. Of Computer ...

some applications are critical and must designed fault tolerant system. usually voting algorithm is one of the principle elements of a fault tolerant system. two kinds of voting algorithm are used in most applications, they are majority voting algorithm and weighted average algorithm these algorithms have some problems. majority confronts with the problem of threshold limits and voter of weight...

This paper surveys recent results on fault-tolerant consensus in message-passing networks. We focus on two categories of works: (i) new problem formulations (including input domain, fault model, network model...etc.), and (ii) practical applications. For the second part, we focus on Crash Fault-Tolerant (CFT) systems that use Paxos or Raft, and Byzantine Fault-Tolerant (BFT) systems. We also br...
