FlashAttention-2: Faster Attention with Better Parallelism and Work Partitioning
Paper summary
FlashAttention-2 improves exact attention implementation through better work partitioning and reduced overhead. The analysis focuses on GPU occupancy, inter-warp communication, and balancing attention against efficient matrix multiplication.
Relevance to the project
Illustrates why GPU performance depends on kernel layout and memory traffic, not only operation counts. Relevant if F later uses attention over bounded histories.
Published speedups require comparable hardware, shapes, and precision.
