The authors present an efficient synchronized checkpointing protocol that exploits the
dependency relation between processes in distributed systems. In this protocol, a process …

Checkpointing reduces loss of computation in the presence of failures. Two metrics
characterize a checkpointing scheme: checkpoint overhead and checkpoint latency. The …

Checkpointing is an effective fault-tolerant technique for improving system availability and
reliability. However, a blind checkpointing placement can result in either performance …

Predictable performance in the event of failuresis of paramount importance in most safety
critical real-timesystems. Various hardware as well as software fault-toleranttechniques are …

On 20 March, 1974, Professor Edward Banfield, of the University of Pennsylvania, was
prevented from delivering a lecture at the University of Chicago. Professor Banfield, who is a …

Many real-time applications require one to many (multicast) communication. Real time
applications can gracefully accommodate some loss but require low delay. We minimize the …

Mitigating the impact of computer failure is possible if accurate failure predictions are
provided. Resources, applications, and services can be scheduled around predicted failure …

This work provides an analysis of checkpointing strategies for minimizing expected job
execution times in an environment that is subject to processor failures. In the case of both …

Most distributed and multiprocessor recovery schemes proposed in the literature are
designed to tolerate arbitrary number of failures. In this paper, we demonstrate that, it is often …

A grid is a distributed computational and storage environment often composed of
heterogeneous autonomously managed subsystems. As a result, varying resource …
