PROFILE

Mandy Li

Mandy J. Li contributed to deep learning infrastructure by enhancing quantization workflows and hardware compatibility across vllm-project/vllm-gaudi and neuralmagic/vllm. She implemented per-channel FP8 weight dequantization and incremental dynamic quantization for Mixture of Experts models, leveraging PyTorch and advanced tensor operations to improve inference efficiency and memory usage on Gaudi accelerators. Mandy also extended cache configuration in neuralmagic/vllm to support Intel HPU block sizes, enabling broader hardware utilization through precise configuration management in Python. Additionally, she improved logging clarity in vllm-gaudi, addressing debugging needs with targeted bug fixes. Her work demonstrated depth in quantization and hardware-aware optimization.

Dec 1, 2025

December 2025 monthly summary for vllm-gaudi focusing on delivering quantization optimizations for MoE models. Implemented per-channel FP8 weight dequantization using a compressed-tensor method and added incremental dynamic quantization (INC) for MoE models by incorporating channel-wise dequantized weights into the MoE operator. These changes enhance inference efficiency and reduce memory footprint for large MoE deployments on Gaudi-backed environments.

Mar 1, 2025

March 2025 monthly summary for red-hat-data-services/vllm-gaudi. Focused on observability quality through a minor, low-risk code-quality fix to improve log clarity. No feature work delivered this month; the effort was a precise correction to logging output to reduce ambiguity during debugging across HPU platforms.
