How do I enable timing summaries for CTSM ports using NUOPC?

[glemieux]

This came up in the ctsm software meeting today when @rgknox noted that his port of CTSM wasn't generating any timing files. I confirmed I was missing the same thing on lobata. The error can be seen in the post run print statement as:

Starting job script case.run
Starting job script case.st_archive
No timing file found in run directory

NUOPC uses the ESMF built in profiler, which is off by default (and doesn't appear to be able to turn ON during ESMF library installation). As such, most machines turn this on in the config_machines.xml file (I neglected to do this with lobata when I added it to the configuration file).

To enable the timing summaries you can add the following to your specific machine configuration:

    <environment_variables comp_interface="nuopc">
      <env name="ESMF_RUNTIME_PROFILE">ON</env>
      <env name="ESMF_RUNTIME_PROFILE_OUTPUT">SUMMARY</env>
    </environment_variables>

Ah, nice find @glemieux - thanks!
