Publisher Summary

Based on distributed and uncoordinated check pointing, numerical methods presented in this chapter can reconstruct a consistent state in parallel application, despite storing checkpoints of various processes at different time steps. The main purpose of these algorithms is to avoid the expensive rollback operation to the last consistent distributed checkpoint, losing all the subsequent work and adding a significant overhead for applications running on thousands of processors because of coordinated checkpoints. The first ...
