Worked on the comfyanonymous/ComfyUI repository, delivering targeted improvements in deep learning model performance, reliability, and maintainability. Addressed dynamic shape export issues by refining image ID initialization and coordinate calculations, which enhanced export stability for end users. Introduced explicit backend prioritization for scaled dot product attention in PyTorch, leveraging efficient backends like Flash Attention and CuDNN Attention to accelerate inference. Implemented elementwise fusion optimizations using torch.addcmul, reducing kernel launches and improving throughput. Additionally, enabled convolution auto-tuning via command-line interface and resolved data type mismatches in RoPE for Llama text encoders, ensuring correctness and compatibility across deployments.
