Move load_compass_env.sh to the ocean dir

[xylar]

Each core will have its own version of this file going forward.

@mark-petersen and @sbrus89, this should be merged after #617 is merged to develop and develop is merged to ocean/develop.

Testing

I tested by setting up the ocean/global_coean/QU240wISC/init test case with and without the --link_load_compass flag (after merging #617 into this branch). Without the flag, there is no load_compass_env.sh link in the test case, as expected. With the flag, the link is there and sourcing it loads the expected compass_0.1.6 environment on Grizzly.

[xylar]

@mark-petersen, and @sbrus89, this should be tested an merged soon, since the load_compass_env.sh script won't be found in its current location anymore.

[mark-petersen]

I just tried this, and it works great. It be exact, on cori:

cd testing_and_setup/compass
source ocean/load_compass_env.sh

and (compass_0.1.6) shows up in front of my terminal prompt. Can then use any of the compass commands.

Sorry for the delay. I can merge today.

[xylar]

@sbrus89, can you verify that the --link_load_compass flag works for you on this branch?

[xylar]

@mark-petersen, please wait until @sbrus89 has approved.

[mark-petersen]

@xylar, I can't get it to work with the --link_load_compass flag, but maybe I misunderstand how to use it. On ocean/develop with this PR merged locally, I try:

cd testing_and_setup/compass
./setup_testcase.py -q -f config.ocean_turq --work_dir /lustre/scratch3/turquoise/mpeterse/runs/nightly/ocean_model_200816_f53d3f0d \
  -n 54 -m runtime_definitions/mpirun.xml --link_load_compass

Traceback (most recent call last):
  File "./setup_testcase.py", line 27, in <module>
    import netCDF4
ImportError: No module named netCDF4

Also tried link_load_compass = True in config file, and get same response. Is that how we are supposed to test?

Do we want a --link_load_compass on manage_regression_suite.py for consistency?

[sbrus89]

@xylar, My link ends up pointing to the compass directory, not the ocean directory.

[xylar]

@mark-petersen, I think you're misunderstanding the purpose. You still have to load compass. This just gives you a local link to the load_compass_env.sh so you can source it, e.g. in a job script. There is no way for the script to load compass for you because it is a python script and needs a working python environment already loaded.

[xylar]

@sbrus89, maybe we need to rebase, since these changes will only work if #617 is included. I'll try locally on my laptop.

[mark-petersen]

@xylar I did misunderstand, thanks.

[xylar]

@sbrus89, it worked for me after a rebase. Could you try again?

[sbrus89]

Thanks @xylar, that works for me now on Grizzly.

[sbrus89]

Approved.

@mark-petersen, yes, that's on my to-do list. It would be modification to develop, so it will take some time to propagate even when it happens.
