We present a new approach to algorithm based fault tolerance (ABFT) for High Performance Computing system. The Algorithm Based Fault Tolerance approach transforms a system that does not tolerate a specific type of faults, called the fault-intolerant system, to a system that provides a specific level of fault tolerance, namely recovery. We have implemented a systematic procedure for introducing ...

Action-level (AL) fault tolerance means to accomplish every critical action (output action of a critical task as speciied) successfully in spite of component failures. Therefore, it is aimed for the highest degree of fault tolerance in real-time computer systems. Several basic techniques developed in recent years for realizing action-level fault tolerance in real-time LAN (local area network)-b...

A Distributed Sensor Network (DSN) consists of a set of sensors that are interconnected by a communication network. DSN is capable of acquiring and processing signals, communicating, and performing simple computational tasks. Such sensors can detect and collect data concerning any sign of node failure, earthquakes, floods and even a terrorist attack. Energy efficiency and fault-tolerance networ...

The OMG’s Real-Time CORBA (RT-CORBA) and Fault-Tolerant CORBA (FT-CORBA) specifications make it possible for today’s CORBA implementations to exhibit either real-time or fault tolerance in isolation. While real-time requires a priori knowledge of the system’s temporal operation, fault tolerance necessarily deals with faults that occur unexpectedly, and with possibly unpredictable fault recovery...

Within the ESPRIT project EFTOS (Embedded Fault-Tolerant Supercomputing), a framework is developed to integrate fault tolerance flexibly and easily into distributed embedded HPC applications . This framework consists of a variety of reusable fault tolerance modules acting at different levels. The cost and performance overhead of generic Operating System and Hardware level fault tolerance mechan...

Cloud computing now a day's become most popular and reliable computing technique for organizations and individuals. In the cloud environments, data availability and backup replication are critical and complex issues in the an efficient fault tolerance policy is the major. Fault tolerance policy is the strategy in action when a fault occurs in the system. Taking backups is the one of the most us...

Grid computing is defined as geographically distributed, heterogeneity (different hardware, software and networks), resource sharing, multiple administrators, dependable access, and Pervasive access within dynamic organizations. In grid computing, the rate of failure is much greater than in traditional parallel computing. Therefore, the fault tolerance is an important property in order to achie...

Masking fault-tolerance guarantees that programs continually satisfy their specii-cation in the presence of faults. By way of contrast, nonmasking fault-tolerance does not guarantee as much: it merely guarantees that when faults stop occurring, program executions converge to states from where programs continually (re)satisfy their speciication. In this paper, we show that an eeective method to ...
