Description

Adds ccpp-physics changes needed to support 32-bit physics on Neptune. This does not add 32-bit physics to FV3, which requires quite a lot more changes in several repositories.

Issue(s) addressed

Implements what this PR was supposed to:

NCAR/ccpp-physics#797

Which is about half of this batch of changes from NRL:

NCAR/ccpp-physics#772

Testing

Original testing was done on Neptune model by NRL. After that, it was tested in UFS, with these changes disabled. Finally, another set of branches (not in this PR) were developed that can successfully compile UFS for 32-bit physics, but not yet run it that way.

• hera.intel (cannot test because Hera stmp is full)
• hera.gnu
• orion.intel
• cheyenne.intel
• cheyenne.gnu
• gaea.intel
• jet.intel
• wcoss_cray
• wcoss_dell_p3
• opnReqTest for newly added/changed feature
• CI

As of this posting, this PR is up-to-date with all components and has passed intel compiler tests (on jet) and gnu compiler tests (on hera).

I have changed the .gitmodules from ssh to https due to permission problems.

Not yet. It is failing after the cleanup of machine.F. I have a fix, and I am testing it now.

We would just be merging in your .gitmodules changes. I will wait until you give me the OK before I run RT's in that PR though.

@BrianCurtis-NOAA It works now. The issue was in FV3/ccpp/physics/machine.F, not the .gitmodules.

I thought the other PR would have closed this. This was merged in #1227
