A few failing nvhpc compiler tests in cmeps1.1.48

[ekluzek]

I found this in CTSM in working on submodules updates on b4b-dev that ultimately became ctsm5.4.044. I've just verified the same tests I had trouble with there fail in cesm3_0_alpha09c.

The three nvhpc tests for aux_clm in CTSM fail at buildtime:

SMS.f10_f10_mg37.I2000Clm50BgcCrop.derecho_nvhpc.clm-crop       ( MODEL_BUILD)
SMS.f45_f45_mg37.I2000Clm60FatesSpRsGs.derecho_nvhpc.clm-FatesColdSatPhen       ( MODEL_BUILD)
SMS_D.f10_f10_mg37.I2000Clm60BgcCrop.derecho_nvhpc.clm-crop     ( MODEL_BUILD)

The build log for cesm.log has this:

NVFORTRAN-S-0084-Illegal use of symbol chkerr - not public entity of module (/glade/derecho/scratch/erik/cesm_alpha/components/cmeps/cime_config/../mediator/esmFldsExchange_cesm_mod.F90: 124)
NVFORTRAN-S-0038-Symbol, chkerr, has not been explicitly declared (/glade/derecho/scratch/erik/cesm_alpha/components/cmeps/cime_config/../mediator/esmFldsExchange_cesm_mod.F90) 
  0 inform,   0 warnings,   2 severes, 0 fatal for esmfldsexchange_cesm

The line referred to is the last in this in mediator/esmFldsExchange_cesm_mod.F90:

  subroutine esmFldsExchange_cesm(gcomp, phase, rc)

    use ESMF
    use NUOPC
    use med_kind_mod          , only : CX=>SHR_KIND_CX, CS=>SHR_KIND_CS, CL=>SHR_KIND_CL, R8=>SHR_KIND_R8
    use med_utils_mod         , only : chkerr => med_utils_chkerr

It is declared public in med_utils_mod as follows...

  public :: med_utils_ChkErr

so I don't see the problem. Unless the nvhpc compiler has an incorrect sensativity to case.

OK, I got it to build by moving the use statment for med_utils_mod::chkerr to the module level. So it must be used in another subroutine besides esmFldsExchange_cesm.

So this diff gets it to build.

There are nvhpc tests in aux_cmeps including a F compset test and this I compset one:

  <test compset="I1850Clm50SpG" grid="f10_f10_mg37" name="ERS_Lm13_P32">

prealpha has this baseline: ERS_Ln9.ne30pg3_ne30pg3_mg17.F2000dev.derecho_nvhpc.cam-outfrq9s_gpu_pcols760

test and it looks like it failed at the build step as well for cesm3_0_alpha09c prealpha testing.
