Worked on alibaba/rtp-llm to expand quantization-driven deployment options and improve distributed model reliability. Developed quantization enhancements for Qwen3-Next/3.5, introducing new linear attention weight management and refined configuration for scalable model optimization. Adapted the ROCm backend for gfx950 hardware, adding FP8 data type support and device compatibility checks. Improved attention mechanisms and KV-cache efficiency by integrating a Triton decoding path and optimizing kernel token handling. Addressed core engine stability by fixing memory management and IPC issues, preventing memory corruption and NaN values in multi-GPU environments. Utilized C++, Python, CUDA, and PyTorch to deliver robust, scalable solutions.
