摘要

Efficient checkpointing of distributed data structures periodically at key moments during runtime is a recurring fundamental pattern in a large number of uses cases: fault tolerance based on checkpoint-restart, in-situ or post-analytics, reproducibility, adjoint computations, etc. In this context, multilevel checkpointing is a popular technique: distributed processes can write their shard of the d...
