@GeorgeGayno-NOAA I encounter a problem when run "chgres_cube" on wcoss2/Acorn. I tried different settings, but the NPETS was always 1, could you give me some suggestions about how to run "chgres_cube" on wcoss2? One log file is located "/gpfs/dell2/ptmp/Xianwu.Xue/o/jgefs_atmos_prep_00.o39015" on Venus. However, the acorn is not available (it suddenly unconnected this afternoon). So I can not tell you where is the log file in wcoss2.

I have not run anything on WCOSS2 yet. My guess is you do not have the mpiexec command correct. Are you starting 36 instances of chgres_cube with one task each?

[XianwuXue-NOAA]

Yes, we use mpirun -n 36 on wcoss_dell_p35

[MatthewPyle-NOAA]

@GeorgeGayno-NOAA I've been trying to get a modified version of the release/ops-hrefv3.1 chgres_cube code compiled on acorn, but struggling a bit. Hoping this href version can piggy back off of your centralized efforts at porting to WCOSS2. Thanks!

How to access the hpc-stack on Cactus from @KateFriedman-NOAA:

module load envvar/1.0
module load PrgEnv-intel/8.1.0
module load craype/2.7.8
module load intel/19.1.3.304
module load cray-mpich/8.1.7

[KateFriedman-NOAA]

@GeorgeGayno-NOAA So my understanding thus far of the stack on WCOSS2 is that those modules access the production installation of the stack but the NCEPLIBS group will also be installing hpc-stack as a dev version (what we know as hpc-stack). FYI, the production installation has some modules that are named slightly differently compared to what we use in hpc-stack now, I'm mainly referring to the hdf5 and netcdf modules accessed after loading the cray-mpich/8.1.7 module (e.g. hdf5-parallel/1.10.6 & netcdf-hdf5parallel/4.7.4). I don't know if that naming difference will persist, I'm using the module names as they are currently set in global-workflow for now. I'll be following convos in the new #wcoss2-transition channel in Slack to see what happens with the stack installs moving forward.

Almost ready to merge.

Checked out the branch at b75f502 on Cactus. All programs were successfully built using the build_all.sh script. And the 'fixed' files were successfully linked using the ./fix/link_fixdirs.sh script.

Next steps - run all consistency tests and utility scripts.

[GeorgeGayno-NOAA]

Next, all the utility scripts were run:

• ./util/vcoord_gen/run.wcoss2.sh was successfully run to create a global_hyblev.txt file.
• ./util/sfc_climo_gen/run.wcoss2.sh was successfully run to create C384 surface climatological field files.
• ./util/gdas_init/driver.wcoss2.sh was successfully run to create C192/C96 GDAS initial conditions using GFS v16 production data from 2022/06/26/06Z.

[GeorgeGayno-NOAA]

Next run the consistency tests. Here, the baseline data was copied over from WCOSS-Dell.

The snow2mdl and ice_blend tests both passed.

[GeorgeGayno-NOAA]

All global_cycle tests passed.

[GeorgeGayno-NOAA]

All chgres_cube tests failed. However, differences with the baseline (from Dell) were small. The largest differences I could find were from the surface portion of the 13km_na_gfs_ncei_grib2 tests:

But these differences are not large enough to be a concern.

[GeorgeGayno-NOAA]

Finally, the grid_gen tests were run. The "C96 uniform" test passed. But the "C96 VIIRS", "GFDL REGIONAL", "ESG REGIONAL" and "REGIONAL GSL GWD" tests failed. However, differences were not concerning. Here are some differences from the "REGIONAL GSL GWD" test -

Note: the cpld_gridgen program does not work on WCOSS2. Due to time constraints (WCOSS2 is now operational), this will be fixed later under #663.
