@jgfouca @bartgol how to ensure this data gets downloaded from the server?

file="true" in the XML for this parameter. However, since you are using a glob here instead of a file name, I'm not sure it will work.

@mahf708 , are you talking about the nudging_filenames_patterns parameter or nudging_refine_remap_mapfile?

@mahf708 @jgfouca did we decide what to do with this issue? Are we simply going to require that users manually download the files beforehand? Or do we want to add logic to our buildnml? I can work on the latter, and may be able to cook up a solution in a day or so, but I wonder if it's too niche of a case to justify adding complexity to our toolchain...

I am leaning towards basically enabling this test as-is (see https://github.com/E3SM-Project/E3SM/pull/7497/files#diff-e2fbf220fd98012c3bdf61d7f341a1815f43823af2ffd3bf926d5aafc4363d8bR762), then it will fail on most machines, and we [people who have access to machines and do blessing, etc. regularly] will manually transfer the files. Then, the tests will pass and we likely won't need to update this test for ~years.

Alternatively, we can just not add the test.

In other words, my vote is to avoid complicating our toolchain

Sounds good. Are you ok taking care of moving the files around for the nightly testing machines once the PR is merged?

Yes, but I may need to ask you/Jim for the SNL machines if that's ok :)

@AaronDonahue, pls tag me in your cdash updates if issues emerge from this test mod (hremap_nudged). We will need to do a fair bit of manual data shuffling, which I will do once we get some fails (let's think of it as a blessing exercise for me)
