BWhat changed
Tracked changed embedding rows, chose intermittent full versus differential checkpoints, and quantized snapshots in background CPU processes while coordinating trainer and data-reader recovery state.
Scientific scope
Tracked changed embedding rows, chose intermittent full versus differential checkpoints, and quantized snapshots in background CPU processes while coordinating trainer and data-reader recovery state. Atomic GPU-to-host snapshots still impose coordination/stall costs; overlapping checkpoints are constrained. Quantization is lossy, so preserved tested quality does not mean bitwise-identical resumed training. Historical checkpoint-size prediction and sampled quantization tuning are heuristics, not guarantees for all failure patterns or distributions.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
