The 45x speedup from fori_loop to vmap wasn’t a better algorithm. It was the same algorithm with one additional piece of information: “these Q blocks are independent.” XLA is a JIT compiler — it does dataflow analysis, operator fusion, memory planning. But it can’t infer independence from a fori_loop with carried state. vmap is semantically “map this function over a batch” — independence is built into the abstraction.

In effect, the explosion of debris helped do the work. Scientists measure that extra boost using something called a momentum enhancement factor. The new analysis finds that the debris roughly doubled the kick delivered by the spacecraft.

Closure Tools consisted of four discrete tools: an optimizing compiler, a template language, a JavaScript framework, and a developer tool. The compiler would eventually become Google’s Closure Compiler and the developer tool would heavily influence the future of Chrome DevTools.
