PROFILE
Yintong Lu
Over a two-month period, contributed core features to the jeejeelee/vllm repository, focusing on efficient model inference and deployment. Developed INT8 compute mode for CPU AWQ, enabling quantized matrix multiplication and improving CPU inference efficiency through kernel-level optimization and quantization techniques in C++ and Python. Later, expanded the XPU MoE backend by implementing GELU-TANH activation support, broadening activation versatility for deep learning models and facilitating wider deployment on XPU hardware. Maintained disciplined code review and collaboration practices, including signed-off and co-authored commits, while demonstrating expertise in CPU optimization, quantization, and deep learning system integration without addressing bug fixes.
