This looks reasonable although one thing that would be good is to use the latest release of Kokkos Core, 4.4.00 at this time, as we do with the current auto-tester. I believe changing from ref: ${{ github.base_ref} to the 4.4.0 tag might be the way to handle that

Also should we actually run the volta 70 jobs to check that they run and pass before merging?

Yea, the CLANG13CUDA check does fail a few tests with #2005.

@ndellingwood, @lucbv: I'd like to get this PR merged, do you know the ctest regex syntax that's needed to exclude the failing tests? e.g., see 8d9a0eb

@e10harvey after merging the BDW PR this now needs a rebase, should be easy. Once you have it done I'll have a final look.

PR #2356 now supersedes this
