Optimizing a Neural Reconstruction Pipeline Using NVIDIA Nsight Developer Tools | NVIDIA Technical Blog

This post details the optimization of the NuRec neural reconstruction pipeline using NVIDIA Nsight Developer Tools. Profiling with Nsight Systems identified inefficiencies in kernel launches and synchronization. Optimizations included fusing small kernels, removing unnecessary synchronization points, and splitting the renderBackward kernel, leading to a ~50x speedup in the interpolate function and improved GPU occupancy. Nsight Compute was used to analyze warp activity and identify workload imbalance.
