in this paper, the impacts of installing superconducting fault current limiter (sfcl)in radial and loop power distribution system are evaluated to improve voltage sag in both cases of with and without distributed generations (dg). among various sfcls, the hybrid type with a superconducting element in parallel with a current limiting reactor (clr) is selected. this is more effective than resisto...

In a fault-tolerant parallel computer, a functional programming model can facilitate distributed checlq3ointing, error recovery, load balancing, and graceful degradation. Such a model has been implemented on the Draper Fault Tolerant Parallel Processor (FTPP). When used in conjunction with the FrPP's fault detection and masking capabilities, this implementation results in a graceful degradation...

The running times of large-scale computational science and engineering parallel applications, executed on clusters or Grid platforms, are usually longer than the mean-time-between-failures (MTBF). Therefore, hardware failures must be tolerated to ensure that not all computation done is lost on machine failures. Checkpointing and rollback recovery are very useful techniques to implement fault-to...

Software almost inevitably contains defects. Do everything possible to reduce the fault rate; Use faulttolerance techniques to deal with software faults. Fault tolerance is the ability of a system to perform its function correctly even in the presence of internal faults. Most of the ordinary systems lack fault tolerant software fix. This paper surveys various software Fault Tolerance techniques...

The increasing demand of low complexity and error tolerant design in signal processing systems is a reliability issue at ground level. Complex circuit is consistently affected by soft errors in modern electronic circuits. Fast Fourier transforms (FFTs) plays a key role in many communication and signal processing systems. Different algorithms have been used in earlier techniques for achieving fa...

MPI has proven effective for parallel applications in situations with neither QoS nor fault handling. Emerging environments motivate fault -tolerant MPI middleware. Environments include space -based, wide -area/web/meta computing, and scalable clusters. MPI/FT , the system described here, trades off sufficient MPI fault coverage against acceptable parallel performance, based on mission requirem...

The paper deals with mesh-connected massively-parallel systems affected by failures. The complexity of a local diagnostic procedure, based on new deenitions of the local k-diagnosability and the r-fault-tolerance, is analysed. It depends on distances between individual fault clusters and on fault cluster diameters. In particular cases the minimum distance between fault clusters can be enlarged ...

In this paper we introduce a new interconnection network Fault Tolerant Hierarchical Interconnection network for parallel Computers denoted by FTH(k, 1).This network has fault tolerant hierarchical structure which overcomes the fault tolerant properties of Extended hypercube(EH).This network has low diameter, constant degree connectivity and low message traffic density in comparisons with other...
