BWhat changed
Partitioned attention along sequence positions, balanced causal-attention work, overlapped key-value transfers and reused memory-efficient attention rematerialization to avoid a redundant forward pass during checkpointing.
Scientific scope
Partitioned attention along sequence positions, balanced causal-attention work, overlapped key-value transfers and reused memory-efficient attention rematerialization to avoid a redundant forward pass during checkpointing. Original version is titled LightSeq; DistFlashAttn is its later bibliographic name, not a second independent contribution. Distinct from unrelated LightSeq inference libraries. Inherits exact online attention and FSDP; speedups and longer contexts are measured configurations, not unrestricted hardware or accuracy guarantees.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.

Contributors
- Source-listed authors and technical contributors · SCIENCE: Source-listed authors or explicitly credited technical contributors for the cited versions. Family entries retain source-specific attribution; a combined list is not one original-paper byline or equal individual work. Names alone do not establish resolved identities.
