" summary

Answers cover TensorFlow behavior and tradeoffs: single‑machine task and data parallelism works out‑of‑the‑box for typical cases; small matrices favor NumPy but TensorFlow wins as graph complexity and iteration count grow; data ingestion prefers feed_dict for in‑memory and queue+multithreaded I/O for large datasets; runtime does constant folding and operator fusion and plans a just‑in‑time graph compiler; custom C++ ops beat many composed ops; production benefits from C++ deployment; distributed multi‑GPU supports sync and async; Cloud ML adds hyperparameter tuning and autoscaling.
