Full Model Testing

Full model system testing of eamxx is done through CIME test cases (much like the rest of E3SM).

We offer a number of test suites, including:

  • e3sm_scream_v0: Test the full set of V0 (pre-C++) tests
  • e3sm_scream_v1: Test the full set of V1 (C++) tests
  • e3sm_scream_v1_at: A smaller and quicker set of tests for autotesting
  • e3sm_scream_hires: A small number of bigger, longer-running tests to measure performance

Example for running a suite:

cd $repo/cime/scripts
./create_test e3sm_scream_v1_at --wait

Example for running a single test case:

cd $repo/cime/scripts
./create_test SMS.ne4_ne4.F2010-SCREAMv1 --wait

There are many behavioral tweaks you can make to a test case, like changing the run length, test type, etc. Most of this is not specific to eamxx and works for any CIME case. This generic stuff is well-documentated here: http://esmci.github.io/cime/versions/master/html/users_guide/testing.html

When it comes to things specific to eamxx, you have grids, compsets, and testmods.

Common EAMxx grids are:

  • ne4_ne4 (low resolution)
  • ne4pg2_ne4pg2 (low resolution with phys grid)
  • ne30_ne30 (med resolution)
  • ne30pg2_ne30pg2 (med resolution with phys grid)
  • ne1024pg2_ne1024pg2 (ultra high with phys grid)

More grid info can be found here: https://acme-climate.atlassian.net/wiki/spaces/DOC/pages/933986549/ATM+Grid+Resolution+Summary

Common EAMxx compsets are:

  • F2010-SCREAM-LR: V0 low res compset with eamxx V0 atmosphere
  • F2010-SCREAMv1: V1 standard compset with eamxx V1 atmosphere
  • FIOP-SCREAMv1-DP: V1 with dpxx (doubly-periodic lateral boundary condition in C++)
  • F2010-SCREAMv1-noAero: V1 without aerosol forcing

Full info on supported compsets can be found by looking at this file: $scream_repo/components/eamxx/cime_config/config_compsets.xml

Common EAMxx testmods are:
