Boosting Swin Transformer Speed: Profiling, Mixed Precision, and Kernel Fusion Secrets

This technical walkthrough explains how Swin Transformer training and inference can be dramatically accelerated on NVIDIA GPUs by using Nsight Systems profiling, mixed‑precision tensor‑core kernels, Apex‑based and custom CUDA operator fusion, half2 vectorization, register‑array caching, and INT8 quantization, achieving up to 2.85× training and 7.34× inference speedups while preserving model accuracy.
