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
