A Coding Guide to NVIDIA’s Tile-Based GPU Programming: From cuTile and Triton Kernels to Flash Attention

1Key Takeaways

• In this tutorial, we explore NVIDIA tile-based GPU programming with TileGym, building a Colab workflow that runs across different hardware.
• We probe the CUDA environment, try the real cuTile backend, and fall back to Triton when standard Colab GPUs lack the cuTile stack.
• We learn the core tile idea: operate on whole data tiles instead of single threads, then load, compute, and store them.
• We implement vector addition, fused GELU, row-wise softmax, tiled matrix multiplication, and flash….
