Worked on improving MoE stability in distributed training for the PaddlePaddle/PaddleFormers repository, focusing on correcting loss computation and gradient synchronization in sequence-parallel mode. Addressed a critical bug by implementing a callback in Python to synchronize gate weights across GPUs during all-reduce operations, ensuring consistent aggregation and reducing training divergence risks. Leveraged skills in callback implementation, deep learning, and distributed training to enhance model optimization and reproducibility. The solution improved training correctness for MoE models in distributed environments, reduced debugging time, and established a more robust foundation for future experimentation with sequence-parallel MoE configurations in large-scale deep learning workflows.
