The third part for stable diffusion CUDA optimizations (1) Add BiasAdd operator to replace two Add (bias and residual); Add fusion for BiasAdd (2) Add Attention fusion for VAE decoder. (3) Update float16 conversion to handle Resize and GroupNorm. This could reduce two Cast nodes for each Resize op in fp16 model. (4) Force inputs and outputs to be float16 to avoid data casts in the pipeline. (5) Add options --force_fp32_ops, --inspect etc in optimize script so that user could force some operator to run in float32 to potentially get better image quality (with cost of performance). Performance tests show slight improvement in T4. Average latency reduced 0.1 seconds (from 5.35s to 5.25s) for 512x512 in 50 steps. |

ONNX Runtime is a cross-platform inference and training machine-learning accelerator.
ONNX Runtime inference can enable faster customer experiences and lower costs, supporting models from deep learning frameworks such as PyTorch and TensorFlow/Keras as well as classical machine learning libraries such as scikit-learn, LightGBM, XGBoost, etc. ONNX Runtime is compatible with different hardware, drivers, and operating systems, and provides optimal performance by leveraging hardware accelerators where applicable alongside graph optimizations and transforms.
