Facebook?s open-source machine learning compiler, Glow, is an example of the tooling evolution. It ?lowers? neural network graphs using a two-phase intermediate representation (IR), which generates machine code that is specially-tuned to the features and memory of a variety of embedded and server-class hardware targets. It also performs ahead-of-time (AOT) compilation, which minimizes runtime overhead to save disk space, memory, startup times, and so on.
