Yugong333

Yu Gong contributed to the jeejeelee/vllm repository by developing and optimizing advanced LoRA and MoE kernel features for deep learning workloads. Over four months, Yu engineered SplitK-enabled fused MoE LoRA kernels, introduced FP8 quantization for shrink and expand operations, and implemented quantized adapter support to improve training and inference throughput. Using CUDA, Python, and PyTorch, Yu focused on performance tuning for NVIDIA GPUs, addressing both scalability and efficiency. The work included refactoring configuration management and benchmarking tools, as well as fixing grid size bounds for reliability. These contributions enabled more scalable, memory-efficient, and robust model deployment workflows.
