Transparent parallel checkpointing and migration in clusters and ClusterGrids
József Kovács · International Journal of Computational Science and Engineering · 2009
This paper introduces a novel approach in parallel checkpointing aimed at supporting fault-tolerance and migration among clusters of a ClusterGrid environment with various middleware components. Based on an architectural analysis, compatibility and integrity requirements are identified and corresponding conditions are established. Some of the available checkpointing systems are checked against the conditions in order to examine their conformity. Finally, a novel checkpointing approach is defined and the Parallel Grid Runtime and Application Development Environment (P-GRADE) Grid Programming Tool is adapted.
