During January 2025, Baippa developed mask-based routing for Mixture-of-Experts (MoE) in PyTorch within the ROCm/TransformerEngine repository. This work introduced mask-based permutation and refactored permutation utilities, enabling scalable and efficient MoE routing for large transformer models. Using C++, CUDA, and Python, Baippa focused on improving routing correctness and model capacity handling, while also enhancing code maintainability. The implementation included comprehensive tests and updated documentation, supporting long-term reliability and easier onboarding. By aligning changes with continuous integration and production standards, Baippa’s contributions established a robust foundation for future MoE development and seamless integration within the ROCm ecosystem.
