[xylar]

The daily config_machines check found upstream changes for one or
more supported machines.

• Generated: 2026-05-07T08:57:11.844937+00:00
• Upstream source: https://raw.githubusercontent.com/E3SM-Project/E3SM/refs/heads/master/cime_config/machines/config_machines.xml
• Upstream revision: ec75ebef661bf4c7ecf72bdcc1710eebdb257d43
• Workflow run: https://github.com/E3SM-Project/mache/actions/runs/25486127836

Required work:

• Run pixi run -e py314 python utils/update_cime_machine_config.py --work-dir . --upstream-revision <sha>
  from the repository root.
• Replace mache/cime_machine_config/config_machines.xml with
  upstream_config_machines.xml generated by that command, then
  remove upstream_config_machines.xml before committing.
• If module or environment changes imply different
  system-package
  versions, update the corresponding mache Spack templates and
  version strings for the affected toolchains.
• Look for related Spack template files under
  mache/spack/templates/<machine>*.yaml,
  mache/spack/templates/<machine>*.sh, and
  mache/spack/templates/<machine>*.csh.
• If the only follow-up is module or version drift, keep the PR
  focused on those updates.
• In the PR summary, state which upstream E3SM commit hash was
  used for the config_machines.xml replacement.
• If any prefix or path values changed and the correct
  replacement
  is not obvious, add a TODO comment in the PR for the reviewer
  instead of guessing.
