NVIDIA cuTile Python Tutorial: Building Tiled GPU Kernels for Vector Addition, Matrix Addition, and Matrix Multiplication in Colab
In this tutorial, we implement an advanced hands-on workflow for NVIDIA cuTile Python, a tile-based GPU programming interface for writing efficient CUDA-style kernels directly in Python. We start by preparing a Colab-friendly environment, checking the available GPU, driver, CUDA, and cuTile installations before running any kernel code. We then build tiled examples for vector addition, matrix addition, and matrix multiplication, while keeping a PyTorch fallback. Hence, the notebook remains executable even when Colab does not meet cuTile’s latest runtime requirements. Through this approach, we understand how tiled programming works, how tensors are loaded, computed, stored, and validated, and how custom GPU kernels can be compared against standard PyTorch operations.
