Why do serving engines capture decode steps into CUDA graphs, and what does capture require of the rest of the code?

Use a timeline to establish launch overhead, then trace what graph replay changes. Stable buffers, page-table updates, capture-safe operations and batch buckets determine whether the serving engine can use it safely.

FEDITOR'S NOTE

Separate exposed host gaps from overlapping dispatch time, explain the lifetime of captured buffers, and test padding and warm-up costs instead of promising a bandwidth-limit speedup.
