Gaea C6 will be down for 2 weeks. Will delay this PR until it returns and passes tests again.

[BrianCurtis-NOAA]

I've ran these changes on Gaeac6, Ursa and am running on WCOSS2 right now. This testing should encompass all changes that I made to add support for GaeaC6. Adding reviewer @DavidHuber-NOAA

[BrianCurtis-NOAA]

@DavidHuber-NOAA we should come back to supporting intel-classic later, and push forward with intelllvm support for now. I've tried using the ss 1.9.2 stack-intel provided and the netcdf wasn't built with that, so it causes issues at compile.

[DavidHuber-NOAA]

@BrianCurtis-NOAA OK, I will approve.

I suspect this is an issue we've managed to circumvent in the global workflow. I'll see what I can figure out. Which test case is the easiest to replicate the issue?

[DavidHuber-NOAA]

Looks good! Thanks!

It's in compile. I'll try getting together a PR with the lua file that will cause the issue.
