PROFILE
Ferrebo
Developed and integrated Data-Parallel Mixture-of-Experts (DP-MoE) support into Zero-Cost Checkpointing (ZCC) for the PaddleNLP repository, enabling efficient training and checkpointing in expert-parallel, distributed environments. Leveraged Python to enhance global expert ID handling, implement IO sharding for DP-Meta gathering, and update ZCC’s EMA loading to ensure correct state_dict restoration across data-parallel ranks. Focused on maintaining optimizer state consistency and improving memory efficiency for large-scale deep learning models. Demonstrated expertise in checkpointing, distributed systems, and model parallelism, laying the foundation for scalable experiments and deployments without introducing major bugs, and maintaining clear code traceability throughout the development process.
