SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Mojo GPU programming has no CUDA syntax, and many developers misunderstand Mojo's GPU model. This section explains how Mojo targets GPUs and accelerators using standard Mojo constructs.

Core Features & Use Cases

  • Clear mappings from CUDA-style ideas to Mojo equivalents (def kernel, ctx.enqueue_function, TileTensor, barrier, and memory contexts).
  • Cross-vendor GPU guidance for NVIDIA, AMD, and Apple Silicon GPUs, including memory management and synchronization patterns.
  • Practical scenarios: writing GPU kernels, building accelerator-aware Mojo code, and teaching Mojo GPU fundamentals.

Quick Start

Create a simple Mojo kernel that doubles a 1D tensor on an available GPU.

Frequently Asked Questions about mojo-gpu-fundamentals

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I write a GPU kernel in Mojo without using CUDA syntax?▼

Mojo GPU kernels use standard language constructs like def kernel and ctx.enqueue_function instead of CUDA syntax. Mojo targets accelerators using std.gpu primitives for device context management and kernel launches.

Does Mojo GPU programming support AMD and Apple Silicon GPUs or just NVIDIA?▼

Mojo GPU programming supports cross-vendor hardware including NVIDIA, AMD, and Apple Silicon GPUs. Kernel definitions, memory management, and synchronization patterns apply across these accelerator targets using standard Mojo constructs.

What is the Mojo equivalent of CUDA thread synchronization and memory contexts?▼

Mojo maps CUDA-style synchronization to barrier functions and memory contexts using std.gpu primitives. TileTensor and device context usage manage memory and coordination across accelerator hardware during kernel execution.

Do I need a CUDA toolkit installed to run Mojo accelerator code?▼

Mojo accelerator code does not require CUDA syntax or a CUDA toolkit. It requires a Mojo language environment and standard GPU primitives from std.gpu to launch kernels and manage device contexts.

What's the best way to translate existing CUDA kernel logic to Mojo?▼

Translate CUDA kernel logic to Mojo by mapping CUDA concepts to Mojo equivalents like def kernel, ctx.enqueue_function, and TileTensor. This avoids common misconceptions about Mojo's GPU model while retaining core algorithm structure.
