PROFILE
Cheng Hang
Chang contributed to NVIDIA/TensorRT-LLM by engineering features that advanced GPU-optimized deep learning workflows. Over three months, Chang developed heuristics-driven tensor parallelism for the language model head, enabling dynamic mappings based on token count and optimizing memory usage in attention data parallelism. Using Python and CUDA, Chang also delivered nvfp4 CUDA core support for SM120 architecture, accelerating tensor computations for AI inference and training. In addition, Chang implemented a weight-only kernel for SM100, enhancing mixed input tensor operations. The work demonstrated depth in distributed systems, model parallelism, and performance optimization, with robust integration into CI/CD and testing pipelines.
