PROFILE

Yilinzhao

Yili Zhao contributed to the alibaba/rtp-llm repository by engineering advanced attention mechanisms and optimizing GPU performance for large language models. Over six months, Zhao refactored RotaryEmbedding with swizzling, introduced device-level swizzle and shuffle logic, and enabled FP8 quantization for ROCm-based attention, all using C++, CUDA, and PyTorch. Zhao also delivered Triton-based attention enhancements, implemented paged prefill support, and developed a robust C++ API for ROCm/aiter, addressing concurrency and input validation. The work focused on improving throughput, memory efficiency, and scalability, demonstrating depth in GPU programming, deep learning, and concurrency management while maintaining code quality and integration readiness.
