CUDA Toolkit

Project Overview

This repository provides the CUDA toolkit (CUDA, cuDNN, and related redistributions) hermetically using Bazel.

It is meant to be consumed by other Bazel projects, notably rulesets and toolchains.

This project had been started to address limitations of the rules_cuda module at the time it was started. rules_cuda now provides the same cuda toolkit configuration, including its own toolchain while this module only provides the toolkit.

Supported versions

Supported versions are defined in:

• cuda/cuda_redist_versions.json

Supported platforms

CUDA components are typically published for these platforms:

• linux-x86_64
• linux-sbsa
• windows-x86_64

This module exposes each component through proxy subpackages:

• @cuda//<component>

These proxy targets are platform-aware and resolve to the correct concrete package for the active Bazel configuration.

For example, @cuda//nvcc:ptxas used from an attribute with cfg = "exec" resolves automatically to the appropriate execution-platform binary.

Recommended usage

Example MODULE.bazel setup:

cuda_ext = use_extension("//extensions:cuda.bzl", "cuda")
cuda_ext.configure(
    cuda_version = "12.9.1",
)
use_repo(cuda_ext, "cuda")

Notes

• cuda_umd_version defaults to cuda_version when omitted.
• CUDA packages under @cuda//<components> are platform-resolving proxies. The selected concrete redistribution is chosen from the current Bazel configuration platform (including exec config).
• For local validation on non-Linux hosts, you can force Linux selection with --platforms=//:platform_linux_amd64 or --platforms=//:platform_linux_arm64.
