PROFILE

Thomas Atta-fosu

Over a three-month period, contributed to the vllm-project/vllm-gaudi and mlcommons/inference repositories by building and optimizing backend systems for multimodal AI and large language model inference. Delivered multimodal support for Qwen2.5-VL-7B, integrating image and video processing into the model’s forward pass and enhancing HPU acceleration. Addressed reliability by fixing batching logic for mixed-modality inputs and aligning output token limits with model constraints in Python and Shell. Improved CI/CD stability for Qwen3-30B-A3B and enabled MoE compatibility through CUDA/HPU programming and deep learning techniques. The work emphasized robust testing, maintainability, and performance optimization for production-ready AI deployments.

February 2025 performance highlights: delivered a precise bug fix in mlcommons/inference to cap generated tokens at 2000 for the llama3.1-405b model, aligning output with the model’s reference limit and preventing excessive generation. The change, implemented in SUT_VLLM.py and recorded in commit 4d0b3589fb1e9d36d1abe17b930ee3a9554ab0e7, enhances reliability, safety, and predictability of inference workflows.
