Walkthrough

The CI workflow configuration was updated to expand the test matrix for the unittest_mpich and unittest_openmpi jobs. Two new ARM-based Ubuntu operating system and Python 3.13 combinations were added, increasing test coverage on ARM architectures. No other workflow logic or steps were modified.

Poem

In the warren where workflows hop and run,
New ARMy friends join in the CI fun.
Ubuntu and Python, on branches they leap,
Ensuring our code is robust and deep.
With every new matrix, our coverage grows—
A bunny’s delight as the pipeline flows! 🐇✨

Note

⚡️ Unit Test Generation is now available in beta!

307-312: Incorrect runner label concern – the existing ARM labels are valid

According to the latest GitHub Actions documentation, public repositories can target ARM64 runners on Ubuntu using these labels:

• ubuntu-22.04-arm
• ubuntu-24.04-arm

Your matrix already specifies exactly those labels, so the workflow will correctly pick up GitHub-hosted ARM64 runners. No changes are needed here.
