Developed a performance-focused feature for the NVIDIA-NeMo/Megatron-Bridge repository, implementing a Segment Tree-based First-Fit Packing Optimization in Python. This work replaced a quadratic-time packing algorithm with a segment tree approach, reducing worst-case complexity from O(N^2) to O(N log N) and improving throughput for large-scale model batch packing. The solution leveraged advanced data structures and algorithm optimization, with careful attention to functional and unit testing. All changes were consolidated under a single, well-documented commit and aligned with broader product goals. The contribution strengthened the pipeline’s scalability and laid groundwork for future optimizations in GPU-accelerated inference workflows.
