Query: Towards Aggregated Asynchronous Checkpointing   High-Performance Computing (HPC) applications need to checkpoint massive
amounts of data at scale. Multi-level asynchronous checkpoint runtimes like
VELOC (Very Low Overhead Checkpoint Strategy) are gaining popularity among
application scientists for their ability to leverage fast node-local storage
and flush independently to stable, external storage (e.g., parallel file
systems) in the background. Currently, VELOC adopts a one-file-per-process
flush strategy, which results in a large number of files being written to
external storage, thereby overwhelming metadata servers and making it difficult
to transfer and access checkpoints as a whole. This paper discusses the
viability and challenges of designing aggregation techniques for asynchronous
multi-level checkpointing. To this end we implement and study two aggregation
strategies, their limitations, and propose a new aggregation strategy
specifically for asynchronous multi-level checkpointing.
