Your question is FlashAttention Concepts. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Describe the concepts behind FlashAttention and why it improves efficiency.
Explain the distinction between compute complexity and memory or IO complexity in standard scaled dot-product attention. Discuss tiled computation, online softmax, reduced high-bandwidth memory traffic, numerical correctness, causal masking, and backward-pass implications. Include a small practical benchmark or pseudocode comparison showing how you would validate correctness, peak memory usage, and latency against standard attention.
