BWhat changed
Combined head and context parallel attention with double-ring exchanges, placement analysis, hybrid ZeRO and Selective Checkpoint++ to improve long-sequence training efficiency.
Scientific scope
Combined head and context parallel attention with double-ring exchanges, placement analysis, hybrid ZeRO and Selective Checkpoint++ to improve long-sequence training efficiency. Shares head/context composition with inherited parallelism work; specific double-ring, placement and checkpoint integration is the systems delta. The2.88fold MFU improvement is a best measured case, not universal or direct total-training-cost reduction. Incidental science examples do not make this a biological contribution.

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
