Non-serial versions of tests using 5x5_amazon failing RUN

[glemieux]

Brief summary of bug

mpibind seems to have an issue with 5x5_amazon resolutions when run with full mpi (i.e. no MPI-serial) since ctsm5.1.dev173. Originally posted at NCAR/mpibind#5.

General bug information

CTSM version you are using: ctsm5.1.dev173

Does this bug cause significantly incorrect results in the model's science? [Yes / No] Run fails so no assessment possible

Details of bug

This was discovered when running the FatesColdSeedDispersal test while generating new fates baselines for the dev173 update. I was able to also replicate this failure using a non-serial MPI version of the hillslope clm-only test. The run immediately fails producing a cesm.log entry with a note about one of the core selections being invalid (see below). It also produced an mpibind.log that I hadn't noticed before.

This prompted me to compare dev172 and dev173 runs for non-serial MPI versions of the hillslope test that use 5x5_amazon. The dev172 version passes, but I noticed that the preview_run output is different:

dev172:

    MPIRUN (job=case.test):
      mpiexec  --label  --line-buffer  -n 5 /glade/derecho/scratch/glemieux/ctsm-tests/tests_mpi-nonserial-check-clm_hillslope/SMS_D_Ld5.5x5_amazon.I1850Clm51Bgc.derecho_gnu.clm-HillslopeC.mpi-nonserial-check-clm_hillslope/bld/cesm.exe   >> cesm.log.$LID 2>&1 

dev173:

    MPIRUN (job=case.test):
      mpibind  --label  --line-buffer  --  /glade/derecho/scratch/glemieux/ctsm-tests/tests_mpi-nonserial-check-clm_hillslope-dev173/SMS_D_Ld5.5x5_amazon.I1850Clm51Bgc.derecho_gnu.clm-HillslopeC.mpi-nonserial-check-clm_hillslope-dev173/bld/cesm.exe   >> cesm.log.$LID 2>&1 

What is odd to me is that mpibind was brought in dev172 via ccs_config_cesm0.0.92, so why is the call not activated for that tag? Why is it only being invoked with dev173?

[glemieux]

@ekluzek given the feedback from NCAR/mpibind#5 (comment), should I make an issue in the ccs_config_cesm repo?

[ekluzek]

@glemieux yes go ahead and do that.

[glemieux]

During the ctsm stand-up meeting today we came up with the following actions for the time being:

• Add a non-serial 5x5_amazon test to aux_clm on derecho and to the expected failure list referencing this issue.
• Temporarily convert the FatesColdSeedDisp testmod to run on f10

It was also noted that this doesn't seem to be an issue for izumi

[ekluzek]

@glemieux note this also relates to another problem I ran into:

#2427 (comment)

where the new use of mpibind needed me to do something different for mksurfdata_esmf.

[ekluzek]

The ccs_config issue is here:

ESMCI/ccs_config_cesm#142

Completed these actions items per #2436.

It seems like the non-serial 5x5_amazon test (SMS_D_Ld5.5x5_amazon.I1850Clm60Bgc.derecho_gnu.clm-HillslopeC) is now passing as of ctsm5.2.027. Should this issue be closed and that test removed from the expected failure list?

[samsrabin]

Actually, it would probably be worth checking whether the original test you noticed this with—the FatesColdSeedDispersal one—still fails.

[ekluzek]

@samsrabin good question on the removal of the MPI version of this test. The utility of the MPI test is to check that MPI works for a simple regional grid. As a way to make sure small regional cases work with MPI in general. It also makes sure you can use MPI for a grid that's only a fraction of a node.

Now at this point we also have the nldas2 grid that we test that's a larger regional grid so we could call that sufficient.

The advantage here though is that 5x5 amazon is a simple, fast, small grid for testing. So I like the idea of keeping it for at least some of our testing, if not this specific test for fates seed dispersal.

[samsrabin]

Thanks, Erik. I am indeed planning (#2434) to keep a serial 5x5_amazon hillslope test in the aux_clm suite, but I've moved the parallel version @glemieux added to just be in the special hillslope suite.

[wwieder]

@glemieux will check on this to see if it's still an issue

[glemieux]

I can confirm that the original issue is resolved. I reinstated the 5x5_amazon test that was changed via e9fb075 and the run passed without issue. I'll make another issue to reinstate the test.
