Description:

Fix a bug in the FV3 write grid component where regional cubed sphere output have undefined (zero) values on some points on the edge (outermost rows and columns). This happens only when model is compiled with -D32BIT=ON option due to round off differences in lat/lon grid coordinate values between forecast and write grid component. When model is compiled without -D32BIT=ON, both forecast and write grid components use 64bit values for grid coordinates and in that case during the remapping all grid points are defined (i.e. 'inside the model domain'). Solution is to use ESMF Redist instead of Remap for all cubed sphere grid outputs.

@DusanJovic-NOAA can you sync up branches? we can start working on this pr.

Done. Do you want me to rerun the regression test on Hera to confirm which tests need new baselines?

I am running on hera to re-confirm. I will keep posting.

@jkbk2004 In commit 65964e1 you updated test_changes.list which removed cpld_debug_pdlib_p8 gnu (65964e1#diff-177386669b623cc6969c192216be1cc1af60d693a02993ad6d2c8656f5907f74) based on your test on Hera. But this test is running (only) on Hercules and will need new baselines. Unfortunately, Hera does not run a superset of all available tests anymore (it used to), so one has to be careful when generating the list of tests which need new baselines.

GaeaC5 and GaeaC6 jobs are still in queue. Both machines are currently very busy.

Is EPIC having any fairshare issues on Gaea?

Current fairshare on C5 epic is 0.559481: bil-fire8on C6 0.636517. Not bad. We can wait until this afternoon and make a decision to skip Gaea or not.

[jkbk2004]

We need to skip GaeaC5/C6. Jobs are not moving on GaeaC5/C6. We will start merging process.
