PROFILE
Zhuoyao Wang
During November 2024, Zhuoyao Wang enhanced distributed training in the ROCm/Megatron-LM repository by implementing gradient synchronization for conditional embedding layers in diffusion transformers. Using PyTorch and C++, Zhuoyao developed an all-reduce mechanism to synchronize gradients across both pipeline and virtual pipeline parallel ranks, ensuring that parameters for timestep, FPS, and label embedders remained consistent across distributed model replicas. This approach addressed divergence issues during large-scale training and improved model stability. The work included comprehensive unit tests to validate synchronization correctness, demonstrating a deep understanding of distributed systems, model parallelism, and the challenges of scalable deep learning infrastructure.
