Relight: Simple User-Level Checkpointing and Fast-Forward Replay for Distributed Task-Based Systems

Checkpointing, or periodic saving of program state to storage, is the de facto standard technique used to mitigate risks of nondeterministic bugs, hardware faults, and job wall-time limits in long-running programs. Traditional approaches require users to manually manage the migra...

A Survey of Distributed Asynchronous Many-Task Models and Their Applications

Asynchronous many-task (AMT) runtime systems have become an important paradigm for expressing fine-grained parallelism and managing asynchrony in high-performance computing (HPC). Originating from early dataflow concepts, AMTs have evolved to enable dynamic task generation, expli...
