PROFILE

Dongji Gao

Worked on enhancing reliability and integration across the NVIDIA/NeMo and NVIDIA/NeMo-Skills repositories, focusing on backend development and job scheduling. Addressed a SLURM GPU job exclusivity issue by correcting sbatch_kwargs mutation, ensuring proper resource allocation and preventing unintended GPU occupancy. Developed vLLM-ready SpeechLM checkpoints and improved multimodal prompting in NeMo, enabling compatibility with Hugging Face transformers and streamlining tokenizer and configuration management. Incorporated unit testing to validate new features and maintain backward compatibility. Leveraged Python, SLURM, and test-driven development practices to reduce operational risk and accelerate deployment of multimodal SpeechLM workflows within complex machine learning pipelines.

April 2026 monthly summary: Focused on reliability, scheduling efficiency, and cross-project integration. Key outcomes include a SLURM GPU job exclusivity fix in NeMo-Skills that prevents unintended GPU occupancy due to sbatch_kwargs mutation, improving resource allocation and throughput. In NVIDIA/NeMo, delivered vLLM-ready SpeechLM checkpoints and enhanced multimodal prompting, ensuring compatibility with Hugging Face transformers; added tokenization/config improvements and unit tests to safeguard backward compatibility. These updates reduce operational risk, accelerate deployment of multimodal SpeechLM workflows, and strengthen the foundation for vLLM-enabled inference. Technologies demonstrated include SLURM scheduling, HF transformers, NeMo's to_hf.py tooling, tokenizer/config handling, and test-driven development.
