PROFILE
Shan-chen-feng
Over a three-month period, contributed to jd-opensource/xllm by developing and optimizing NPU-accelerated features for distributed deep learning and image processing workloads. Work included stabilizing NPU-based distributed execution, implementing hardware-accelerated image editing pipelines, and enhancing model support for Qwen3, Oxygen, Atb, and Qwen-Image. Leveraged C++ and PyTorch to deliver parallel computing solutions, optimize memory usage, and improve performance-per-watt in production environments. Addressed process group compatibility issues and runtime errors through targeted debugging and backend development. The technical approach emphasized scalable deployment, efficient caching strategies, and integration of ACL-based backends, resulting in improved throughput and reliability across multiple models.
