Code Review

This pull request adds a new XPU disaggregated accuracy test to the CI script and updates the UCX and NIXL versions in the XPU Dockerfile. Feedback was provided regarding a redundant pip installation command in the Dockerfile that could lead to build errors or incorrect package versions.

why need uv pip install nixl==${NIXL_VERSION}

[zhenwei-intel]

pip install . only generates nixl-cu12 (implementation package), the meta package nixl needs to be installed manually.

[xuechendi]

meaning we don't need build from source any more, is that correct?

[zhenwei-intel]

Now nixl will provide two python packages: nixl(meta package), nixl-cu12/nixl-cu13(implementation package)

we still need build nixl-cu12 from source, but nixl can be install by pip.

[jikunshang]

I am confused that why we need nixl-cu12

[zhenwei-intel]

for v0.10, two packages are needed, nixl-cu12/nixl-cu13 is package of implementation, and indeed the name is a bit ambiguous.

Hi @zhenwei-intel, the pre-commit checks have failed. Please run:

uv pip install pre-commit>=4.5.1
pre-commit install
pre-commit run --all-files

Then, commit the changes and push to your branch.

For future commits, pre-commit will run automatically on changed files before each commit.

Tip

Is mypy failing?

mypy is run differently in CI. If the failure is related to this check, please use the following command to run it locally:

# For mypy (substitute "3.10" with the failing version if needed)
pre-commit run --hook-stage manual mypy-3.10

nixl>=1.1, xpu has some issues in this version, I am trying to fix.

Can we merge this now before it gets outdated again? And continue the NIXL 1.1 fix on separate PR.
