Zhiyuan Li
Worked on performance optimization and backend development for AI inference and autotuning systems, focusing on repositories such as ggerganov/llama.cpp, Mintplex-Labs/whisper.cpp, and intel/intel-xpu-backend-for-triton. Delivered operator optimizations and architectural enhancements for RWKV6/WKV6, emphasizing multi-core CPU and SYCL acceleration, cross-hardware compatibility, and standardized naming conventions using C, C++, and CUDA. Improved tensor operation handling and expanded support for AVX2, AVX512, ARMv8, and ARMv9 architectures. Addressed autotuning reliability by fixing benchmarking configuration handling and removing deprecated parameters, resulting in more stable performance tuning workflows and streamlined onboarding for developers working with these codebases.
