Paul Mifsud developed GPU-accelerated graph proximity features for the ClementiGroup/mlcg repository, focusing on scalable radius graph and distance calculations. He implemented optimized CUDA kernels with Python wrappers, enabling fast, large-scale graph computations and improving data processing throughput. In a subsequent refactor, Paul unified the radius calculation logic to support PyTorch autograd, allowing backpropagation through radius computations in SchNet training loops. He removed legacy CUDA code, updated the file structure, and expanded test coverage to ensure training compatibility. His work demonstrated depth in CUDA programming, Python, and performance optimization, resulting in more maintainable, extensible, and efficient graph neural network pipelines.

February 2025 – ClementiGroup/mlcg: SchNet Radius Calculation Refactor with Autograd Integration. Delivered a backward-compatible radius computation path enabling backpropagation through radius in training loops, and consolidated the radius logic into a single maintainable code path. Removed the legacy CUDA-based radius implementation and refactored CUDA kernel calls with updated file structure. Updated tests to cover backward functionality and training-loop compatibility, establishing a solid foundation for end-to-end SchNet training. Overall, this work improves training stability, maintainability, and prepares groundwork for future kernel optimizations.
