FlashAttention: Fast and Memory-Efficient Exact Attention with IO-Awareness
Efficient training and inference / 2022 / core
Summary
FlashAttention shows how attention speed depends on memory movement, not just arithmetic, and redesigns the kernel around IO-aware tiling.
Why George Should Read It
It is a useful reminder that AI progress often comes from systems work that changes practical cost curves.
Best For
- inference cost analysis
