nvhpc compiler tests are failing on cheyenne

In the CESM3_dev branch two of the tests now PASS: SMS.f10_f10_mg37.I2000Clm50BgcCrop.cheyenne_nvhpc.clm-crop FAILED PREVIOUSLY While this one still fails, but now with a floating point exception SMS_D.f10_f10_mg37.I2000Clm51BgcCrop.cheyenne_nvhpc.clm-crop EXPECTED The cesm.log file shows that there is a problem in ESMF at initialization in creating an ESMF mesh. It doesn't drop PET files by default in this case... cesm.log: |

Seeing similar errors on Derecho: These PASS: These FAIL: The fails are all in the build now with error message from FATES code like this: Looking at the code I don't see an obvious problem. I googled about it and there are some NVIDIA nvhpc reports about these kind of errors. But, it's not obvious what the issue is here or how to fix it. |

A reminder that nvhpc is important for the flexibility to be able to start using GPU's, and since Derecho has NVIDIA GPU's nvhpc is going to be the most performant compiler on Derecho for it's GPU's. Even though GPU's don't currently look like they are important for most uses of CTSM. This will be important for ultra high resolution. And in the future as hardware changes it's important to have flexibility in the model to take advantage of different types of hardware in order to keep the model working well. |

Corrected that Derecho has NVIDIA GPU's.. And from talking with @sherimickelson and slides presented by her group on Sep/12th/2023 CSEG meeting, nvhpc and cray compilers work for the Derecho GPU's, but intel-oneapi wasn't at the time. |

This is great news and thanks, @ekluzek for sharing this and for your support. |
Brief summary of bug
MPI tests with DEBUG on are failing at runtime with the nvhpc compiler on cheyenne.
This continues in ctsm5.1.dev155-38-g5c8f17b1a (derecho1 branch) on derecho
General bug information
CTSM version you are using: ctsm5.1.dev082 in cesm2_3_alpha08d
Does this bug cause significantly incorrect results in the model's science? No
Configurations affected: tests with nvhpc and DEBUG on
Details of bug
These tests fail:
SMS_D.f19_g17.IHistClm50Bgc.cheyenne_nvhpc.clm-decStart
