PROFILE
Shan-chen-feng
Shanchen Feng contributed to the jd-opensource/xllm repository by developing an NPU-accelerated image editing pipeline and stabilizing distributed execution for DiT compatibility. Using C++ and leveraging expertise in image processing, machine learning, and parallel computing, Shanchen implemented the QwenImageEditPlus pipeline with optimized caching and parallel processing, improving throughput and responsiveness on NPU devices. Additionally, Shanchen addressed a critical bug in the NPU process group, ensuring accurate rank and world size retrieval while preventing conflicts in environments lacking HCCL/NCCL support. The work demonstrated a focused, incremental approach, laying a foundation for scalable deployment and future hardware-backed integration within the project.
