| Abstract(in English) | Checkpointing parallel processes causes high temporal and spatial pressure to I/O subsystems. To decrease the pressure, we propose a new Checkpointing technique, called Speculative Checkpointing, that improves upon incremental checkpointing by speculatively distributing the checkpointing workload and avoiding the necessity of file synchronization. Experimentation with our prototype Speculative Checkpointer on a variety of parallel workload on a cluster showed marked improvements when speculation works effectively, exhbiting up to 33% improvement over conventional incremental checkpointing schemes. We expect that, in a production environment with larger number of nodes and dedicated backend checkpointing storage this improvement would be even higher. |
