Walkthrough

The changes update CUDA version requirements and workflow matrix selections to CUDA 13.4 across dependency configuration, build and test workflows, release image defaults, and contributor setup instructions.

Changes: CUDA 13.4 migration

Layer / File(s) Summary
CUDA 13.4 dependency and environment definitions
dependencies.yaml, conda/environments/all_cuda-134_arch-*.yaml, python/libcuopt_*/pyproject.toml
The default CUDA matrix and CUDA 13.4 dependency mappings are updated. The environment files require CUDA 13.4, and the nvidia-nvjitlink minimum versions are raised to 13.4.
CI workflow matrix selection
.github/workflows/build.yaml, .github/workflows/pr.yaml, .github/workflows/test.yaml, .github/workflows/self_hosted_service_test.yaml
Build and test jobs specify CUDA 13.4 matrix types. The self-hosted test workflow accepts an optional matrix_type input and passes it to matrix computation.
Release defaults and local setup
.github/workflows/build_test_publish_images.yaml, ci/release/publish_placeholder_release_images.sh, CONTRIBUTING.md
The image publishing CUDA default changes to 13.4.3, and the contributor environment command selects the CUDA 13.4 environment file.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Suggested reviewers: ramakrishnap-nv

Merge Risk: Minimal · up to f5320

The reviewed workflows select the intended CUDA 13.4 matrix for Java static builds and tests, so no actionable merge-blocking risk remains.

Full details: Title check

Explanation

The title states the main change: the build and test environment moves to CUDA 13.4.3. The raw summary confirms this. Most workflow, conda environment, dependency, and script changes switch the default CUDA 13 version from 13.3 to 13.4 or 13.4.3, and add a cuda-13-4 matrix type. The title is specific and matches the changeset, so it passes.

Full details: Description check

Explanation

The description says the PR contributes to rapidsai/build-planning issue #335. It also says the PR uses CUDA 13.4.3 to build and test and updates the CUDA 13.4.3 devcontainers. These points match the changeset, which changes CI workflows, conda environment files, dependency pins, and release scripts to CUDA 13.4. The description is brief but specific enough, so it passes.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 1 files. (1 skipped: 1 unsupported.)

Select CUDA 13.4 for the static Java build.

This matrix still uses auto, which currently selects CUDA 13.3.0. The published CUDA 13 classifier JAR is therefore built with CUDA 13.3.0, not 13.4.3. Set matrix_type: cuda-13-4-nightly here, and update the matching static Java matrices in pr.yaml and test.yaml. (raw.githubusercontent.com)

Weird. Looks like we are still seeing telemetry failing in CI

It says it is non-blocking. Though it shouldn't be here at all

Will try updating the branch again to see if that helps

The label checker wasn't running. So removed and readded a label to run it

The branch checker still appears stuck.

For some reason we still see telemetry running in cuOpt and failing. It seems to hold up merges even though it is non-blocking. Appears there are still some telemetry bits in cuOpt that need to be removed.

For some reason we still see telemetry running in cuOpt and failing. It seems to hold up merges even though it is non-blocking. Appears there are still some telemetry bits in cuOpt that need to be removed.

I think by "telemetry bits" you're implying that something related to the now-removed RAPIDS CI telemetry (e.g. rapidsai/shared-actions#157) is failing, but I don't see that.

At that link, I see this failure

Traceback (most recent call last):
  File "/home/runner/work/cuopt/cuopt/ci/utils/pr_test_summary.py", line 325, in <module>
    main()
    ~~~~^^
...
  File "/usr/lib/python3.14/urllib/request.py", line 611, in http_error_default
    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 502: Bad Gateway

That's from code in this repo: https://github.com/NVIDIA/cuopt/blob/ea0adadea5092d8deb45e8adf76796fb4b6dbabb/ci/utils/pr_test_summary.py

That as far as I can tell has nothing to do with the RAPIDS telemetry stuff.

Yes, it is customization from cuopt to capture the failures, I don't know why but it has been more flaky and failures are more often due to api.

Ok perhaps I don't understand cuOpt's CI configuration. These failures were confusing though. And it would be nice to fix them

@ramakrishnap-nv is there an issue tracking fixing this issue? If not, could you please file one and link it here?
