Scalable Diskless Checkpointing for Large Parallel Systems

A Novel Multi-core System for Fault Tolerance and Security with Diskless Checkpointing Capability

Improving fault tolerance within the clusters has become vital because of the drastic decrease in the Mean Time Between Failures (MTBF) in complex clusters. Checkpointing is one of the robust ways to improve fault tolerance by rolling back from a saved state in the event of a failure in the cluster. Since, checkpointing primarily relies on storage devices for storing the states at regular inter...

Efficient Diskless Checkpointing and Log Based Recovery Schemes

Checkpointing and message logging are the popular and generalpurpose tools for providing fault tolerance in distributed systems. Diskless checkpointing schemes enable frequent checkpointing without a performance penalty. The present work extends James S Plank‟s Diskless checkpointing scheme (N+1 Parity) by introducing ‘Timeout’ mechanism to checkpoint programs with high locality of reference. T...

Fault Tolerance and Checkpointing

Research and applications of clusters of workstations are growing rapidly. One of the major area is fault tolerance. This report describes two issues concerned: correctness and performance. After a number of techniques to improve performance are described, new research directions, diskless checkpointing and Java checkpointing, are introduced.

A Diskless Checkpointing Algorithm for Super-scale Architectures Applied to the Fast Fourier Transform

This paper discusses the issue of fault-tolerance in distributed computer systems with tens or hundreds of thousands of diskless processor units. Such systems, like the IBM BlueGene/L, are predicted to be deployed in the next five to ten years. Since a 100,000-processor system is going to be less reliable, scientific applications need to be able to recover from occurring failures more efficient...
