Glow is a machine learning compiler and execution engine for various hardware targets. It is designed to be used as a backend for high-level machine learning frameworks. The compiler is designed to allow state of the art compiler optimizations and code generation of neural network graphs. This library is experimental and in active development.
High-Level Graph => Low-Level IR => Machine Code
これって、TensorFlow XLA の TensorFlow GraphDef => TensorFlow XLA (HLO => LLO) と同じ感じですね。。。
最適化:Glow optimization passes、グラフの最適化とIRの最適化 (学習&推論時の性能およびメモリ使用量)
