A Coding Guide to NVIDIA’s Tile-Based GPU Programming: From cuTile and Triton Kernels to Flash Attention
NVIDIA's tile-based GPU programming isn't just faster—it's becoming the standard for inference optimization. Here's how to build with it.

Why it matters
As AI inference costs dominate operational budgets, mastering tile-based GPU programming (cuTile, Triton, Flash Attention) is becoming a core competency for ML engineers. This tutorial bridges the gap between NVIDIA's low-level optimization primitives and production implementation.
The key facts
11 to knowTutorial covers cuTile backend and Triton kernel fallbacks for hardware compatibility
Core tile programming model: batch data into tiles, load → compute → store

Publisher excerpt: 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…
