Build and test with CUDA 13.2.0 by bdice · Pull Request #1198 · NVIDIA/cuopt

bdice · 2026-05-11T20:13:41Z

Contributes to rapidsai/build-planning#265

Closes#1155.

uses CUDA 13.2.0 to build and test
updates to CUDA 13.2.0 devcontainers

Notes for Reviewers

This switches GitHub Actions workflows to the cuda-13.2.0 branch from here: rapidsai/shared-workflows#545

A future round of PRs will revert that back to main, once all of RAPIDS is migrated.

📝 Walkthrough

Walkthrough

This PR updates the project's CUDA toolchain from version 13.1 to 13.2 across build/test CI workflows, dependency matrices, conda environment files, and CONTRIBUTING documentation, and pins reusable workflow references to @cuda-13.2.0.

Changes

CUDA 13.2 Version Upgrade

Layer / File(s)	Summary
Dependency Matrix Configuration `dependencies.yaml`	Top-level CUDA build matrix, conda version dependencies, and CUDA toolkit requirements are updated from CUDA 13.1 to 13.2.
Conda Environment Specifications `conda/environments/all_cuda-132_arch-*.yaml`	Generated Conda environment files for both ARM64 and x86_64 are renamed and updated with `cuda-version=13.2` and environment name `all_cuda-132_arch-*`.
Development Documentation `CONTRIBUTING.md`	Conda environment setup command is updated to reference the CUDA 13.2 environment file.
Build Pipeline Workflow `.github/workflows/build.yaml`	All reusable workflow references for conda/wheel builds, uploads, publishes, and docs are pinned from `@main` to `@cuda-13.2.0`.
PR Pipeline Workflow `.github/workflows/pr.yaml`	All reusable workflow references for build checks, conda/wheel build/test jobs, and documentation are pinned from `@main` to `@cuda-13.2.0`.
Test Pipeline Workflow `.github/workflows/test.yaml`	Reusable workflow references for conda and wheel testing are pinned from `@main` to `@cuda-13.2.0`.
Image Build Workflow Defaults `.github/workflows/build_test_publish_images.yaml`	Default CUDA version input is updated from `["12.9.0", "13.1.0"]` to `["12.9.0", "13.2.0"]`.
Breaking Change Alert Workflow `.github/workflows/trigger-breaking-change-alert.yaml`	Shared workflow reference is pinned from `@main` to `@cuda-13.2.0`.
CMake CUDA-version Condition `cpp/CMakeLists.txt`	CMake conditional changed from `VERSION_LESS_EQUAL 13.2` to `VERSION_LESS 13.2` for applying `CCCL_DISABLE_WARPSPEED_SCAN`.

Thank you @bdice for the PR, several of the engine team were waiting for this update.

bdice · 2026-05-14T17:43:31Z

rapidsai/rapids-cmake#1022 has been merged, which should fix the Blackwell test failures.

Authors: - Bradley Dice (https://github.com/bdice) - Ramakrishnap (https://github.com/rgsl888prabhu) Approvers: - James Lamb (https://github.com/jameslamb) - Ramakrishnap (https://github.com/rgsl888prabhu) URL: NVIDIA#1198

The nightly main scan has been failing since 2026-05-15 because PR #1198 bumped main from CUDA 13.1 to 13.2 (replacing `all_cuda-131_arch-*.yaml` with `all_cuda-132_arch-*.yaml`), but `run-sonar-analysis.sh` still pointed at the deleted 13.1 yaml. Detect inside the per-branch loop: glob `conda/environments/`, version-sort, take the newest. `release/26.04` keeps using `cuda-131` (still on disk there); `main` now picks `cuda-132` automatically; future bumps need no script change. Loud failure if no matching env file exists at all. Authors: - Ramakrishnap (https://github.com/rgsl888prabhu) Approvers: - Ishika Roy (https://github.com/Iroy30) URL: #1236
