@brian-eaton Is there a reason not to use rrtmgp here?

The nvhpc test that uses these mods fails when radiation is set to rrtmgp, or rrtmgp_gpu. I tried both. The error looks like this:

deg0062.hsn.de.hpc.ucar.edu 110: Failing in Thread:1
deg0062.hsn.de.hpc.ucar.edu 110: Accelerator Fatal Error: call to cuStreamSynchronize returned error 700 (CUDA_ERROR_ILLEGAL_ADDRESS): Illegal address during kernel execution

deg0062.hsn.de.hpc.ucar.edu 110:  Line: 623

Since the purpose of this PR is just to change the default to rrtmgp for the LT and MT configurations I didn't take the time to chase down the problem with this test, but instead left it using rrtmg as it was already doing. I can update the test in a future PR, or in this one if you know what the problem is.

Thanks Brian for your update. I see where the problem is. This folder is used by the GPU regression test and the EarthWorks team has identified that there is a problem to run CAM with the default RRTMGP kernels on the GPU. In order to run it correctly, we either need to update the CAM->RRTMGP interface (like this EarthWorksOrg#25) or update the RRTMGP kernel (like this EarthWorksOrg/rte-rrtmgp@ac0f76e). Otherwise, the rrtmgp_gpu option is not expected to work properly here. I am surprised that the rrtmgp option is not working either as it should only turn on the RRTMGP CPU code. But the GPU tests may turn on some ACC directives accidentally. Do you have an error message for the rrtmgp option? The error message posted here seems coming from the rrtmgp_gpu option.

Hi Jian. I got a similar error message with the rrtmgp option (which in this PR is the default radiation for cam7). The test that's failing, and a sample of the error output:

I'm running regression tests now for this PR and plan to leave this test as it has been using rrtmg. It would be good if you could open an issue if you want to get this test running with the rrtmgp_gpu option.

Thanks Brian. The file you pointed to also has ACC directives and it means even using the rrtmgp option, some code will still be enabled on the GPU by the GPU regression test. I guess it won't work properly if only part of the RRTMGP GPU code is activated. I agree that we can just use rrtmp option here and address this problem in a separate issue. I just want to understand what is going on here. Thanks for your help and clarification.

One-line Summary: Make RRTMGP default radiation in CAM7
Github PR URL: https://github.com/ESCOMP/CAM/pull/1178

Purpose of changes (include the issue number and title text for each relevant GitHub issue):

. Issue #1143 - turn RRTMGP on by default for CAM7 + some namelist defaults

. Remove some tests that added rrtmgp to the cam7 configuration. Not
needed since rrtmgp is now the default in cam7.

. Remove test of old cam7 development configuration (32 levels) which is no
longer needed.

. Remove 13 month F2000climo test. This was originally created to make
sure we didn't make changes that hurt the performance of our production
configuration for CMIP6 simulations. This is no longer needed.

. Issue #1154 - Create at least one CAM7 regression test on izumi
- add ERP_D_Ln9.ne3pg3_ne3pg3_mg37.FLTHIST.izumi_gnu.cam-outfrq9s_eoy


Describe any changes made to build system: none

Describe any changes made to the namelist:

. change default value of seasalt_emis_scale to 0.75 for cam7 (both lt and mt)

. update ubc_file_path for cam7 (lt only) to
atm/cam/chem/ubc/b.e21.BWHIST.f09_g17.CMIP6-historical-WACCM.ensAvg123.cam.h0zm.H2O.1849-2014_c240604.nc

List any changes to the defaults for the boundary datasets:

Describe any substantial timing or memory changes:

Code reviewed by:

List all files eliminated:

cime_config/testdefs/testmods_dirs/cam/outfrq1d_14dec_ghg_cam7/*
. test removed

List all files added and what they do:

cime_config/testdefs/testmods_dirs/cam/outfrq9s_eoy/*
. new test like outfrq9s, but add RUN_STARTDATE="1999-12-31" and
START_TOD="82800" so that the run goes over the end of year boundary.

List all existing files that have been modified, and describe the changes:

bld/configure

bld/namelist_files/namelist_defaults_cam.xml

. add '-rad rrtmg' to CAM_CONFIG_OPTS. This test is using a non-standard
configuration of cam7, and this override is needed since the default
radiation scheme for cam7 has changed to rrtmgp.
