AT2 CI Build Transition -- GCC + OpenMPI

[sebrowne]

The AT2/gcc10-openmpi4 Action is planned to be set to ‘required’ on Monday 03/03/2025.

Monitoring of this CI build has shown a high pass rate since 02/01/2025. There have been no systemic issues detected during that time (all issues have been "real" failures from issues with code).

The corresponding line (rhel8_sems-gnu-8.5.0-openmpi-4.1.6-serial_debug_shared_no-kokkos-arch_no-asan_no-complex_no-fpic_mpi_no-pt_no-rdc_no-uvm_deprecated-on_no-package-enables) that runs through the AutoTester1 system will be set to non-blocking accordingly, and will then soon be decommissioned.

No other CI builds will be modified at this time. Announcements will be made for any subsequent CI build transitions.

Please open an issue at https://github.com/trilinos/Trilinos/issues and tag the trilinos/framework team if you encounter any issues that you think are related to this change.

An email will also be sent to the trilinos-developers mailing list.
Known Issues

If you see an error like the one here and you are an external collaborator, you will need somebody from the internal development team to re-run the failed workflow (it should then get past that issue).

If your PR is not being allowed to merge despite the check passing, please check to ensure that the correct check is being used. Below see an example of the INCORRECT (old) name for the check. Resolve this issue by updating your branch via a rebase or merge with the develop branch.

Check has been set to required, and AT1 build has been set to non-blocking. Will hold this announcement open until the AT1 build is removed.
