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

Mojo GPU programming uses LayoutTensor and host-device interop to define kernels without CUDA syntax. This enables writing portable GPU code that runs across NVIDIA, AMD, and Apple Silicon accelerators.

Can I run the same Mojo GPU kernel on AMD and Apple Silicon?▼

Yes, CUDA-free Mojo GPU kernels target multiple accelerators including AMD and Apple Silicon. Using Mojo LayoutTensor and shared memory patterns ensures portable execution across these diverse GPU hardware targets.

What is Mojo LayoutTensor used for in GPU programming?▼

Mojo LayoutTensor manages memory layouts for GPU kernels without CUDA syntax. It facilitates host-device interop and shared memory patterns, enabling portable GPU code across NVIDIA, AMD, and Apple Silicon accelerators.

Does Mojo support shared memory patterns for GPU development?▼

Yes, Mojo supports shared memory patterns for GPU development. It enforces CUDA-free kernel definitions using Mojo LayoutTensor, enabling portable shared memory optimization across NVIDIA, AMD, and Apple Silicon GPUs.

Why should I use Mojo instead of CUDA for portable GPU code?▼

Mojo avoids CUDA syntax quirks that hinder portability across hardware. It uses Mojo LayoutTensor and CUDA-free kernel definitions to enable portable GPU code targeting NVIDIA, AMD, and Apple Silicon accelerators.

How do I perform host-device interop in Mojo GPU programming?▼

Host-device interop in Mojo GPU programming uses Mojo LayoutTensor and CUDA-free kernel definitions. This enables portable data transfer and kernel execution across NVIDIA, AMD, and Apple Silicon GPU accelerators.
