PROFILE
Jinyang He
Jinyang He focused on low-level performance engineering for LoongArch CPUs, delivering targeted optimizations and stability improvements across multiple open-source repositories. In ggml-org/llama.cpp and Mintplex-Labs/whisper.cpp, Jinyang enhanced quantized inference by optimizing floating-point conversions, extending integer handling, and accelerating vector dot products using C and assembly. These changes improved runtime efficiency and consistency for quantized workloads. In mozilla/onnxruntime, Jinyang addressed a strict aliasing warning and corrected the transpose store operation, ensuring reliable matrix computations and aligning with MLAS optimizations. The work demonstrated strong expertise in C++ development, CPU architecture, and performance tuning, resulting in more robust LoongArch deployments.
