Overview

"For the things we have to learn before we can do them, we learn by doing them." — Aristotle, (Nicomachean Ethics)

Welcome to Mojo🔥 GPU Puzzles — an interactive approach to learning GPU programming through hands-on puzzle solving. Instead of traditional textbook learning, you'll immediately dive into writing real GPU code and seeing the results.

Why Mojo🔥

Mojo represents a revolutionary approach to GPU programming, making massive parallelism accessible while maintaining systems-level performance:

• 🐍 Python-like Syntax with systems programming capabilities
• ⚡ Zero-cost Abstractions that compile to efficient machine code
• 🛡️ Strong Type System catching errors at compile time
• 📊 Built-in Tensor Support with hardware-aware optimizations
• 🔧 Direct Hardware Access to CPU and GPU intrinsics
• 🔄 Cross-Hardware Portability for CPUs and GPUs
• 🎯 Ergonomic Improvements over traditional C/C++

Getting Started

Prerequisits

You'll need a compatible GPU to run the examples.

1. Visit https://builds.modular.com/puzzles

2. Clone this repository

   git clone https://github.com/modular/mojo-gpu-puzzles
   cd mojo-gpu-puzzles

3. Install a package manager to run the Mojo🔥 programs:

   Option 1: uv (recommended for users)

   Install:

   curl -fsSL https://astral.sh/uv/install.sh | sh

   Update:

   uv self update

   Create a virtual environment:

   uv venv && source .venv/bin/activate

   Option 2: pixi (recommended for contributors)

   Install:

   curl -fsSL https://pixi.sh/install.sh | sh

   Update:

   pixi self-update

4. Start solving puzzles!

Development

We use pixi for development as it includes uv and also supports conda packages (like mdbook from the conda-forge channel) needed for development workflows.

# Build and serve the book
pixi run book

# Test solutions on GPU
pixi run tests

# Format code
pixi run format
