As an NN compiler, Glow takes in an unoptimized neural network and generates highly optimized code. Node Lowering • Instead of compiling high-level operators directly, Glow performs “node lowering” • In this phase, the compiler breaks the high-level operator nodes into low-level linear algebra operator nodes • For example, the FullyConnected layer is represented as a matrix multiplication followed by broadcasted add • Different compiler backends do not have to implement the FullyConnected layer … Similarly, the DL compilers take the DL models described in different DL frameworks as input, and then generate … We work to provide PyTorch and other frameworks with a low-level graph and a code generator for neural networks. Glow is a neural network compiler that optimizes neural networks for specific target hardware. The Facebook Glow compiler “Glow: Graph lowering compiler techniques for neural networks” paper.
