+One-line Summary: Fix broken GPU tests for CLUBB code
+Github PR URL: https://github.com/ESCOMP/CAM/pull/1226
+
+Purpose of changes (include the issue number and title text for each relevant
+GitHub issue):
+
+This PR fixes the broken ERS tests due to the recent GPU changes of CLUBB code
+(PR #1175).
+
+Note that this PR need a new ccs_config tag from ESMCI/ccs_config_cesm#204 to
+complete this PR.
+
+Closes #1220 - GPU test fails restart comparison
+
+Describe any changes made to build system: N/A
 
+Describe any changes made to the namelist: N/A
+
+List any changes to the defaults for the boundary datasets: N?A
+
+Describe any substantial timing or memory changes: N/A
+
+Code reviewed by: nusbaume
+
+List all files eliminated: N/A
+
+List all files added and what they do: N/A
+
+List all existing files that have been modified, and describe the changes:
+
+M       .gitmodules
+ - Update ccs_config to ccs_config_cesm1.0.21 (needed for test fix)
+
+M       src/physics/cam/clubb_intr.F90
+ - Move variables from OpenACC create to copy call to fix restart test.
+
+If there were any failures reported from running test_driver.sh on any test
+platform, and checkin with these failures has been OK'd by the gatekeeper,
+then copy the lines from the td.*.status files for the failed tests to the
+appropriate machine below.  All failed tests must be justified.

+Summarize any changes to answers, i.e.,
+- what code configurations:
+- what platforms/compilers:
+- nature of change (roundoff; larger than roundoff but same climate; new
+  climate):
+
+If bitwise differences were observed, how did you show they were no worse
+than roundoff?
+
+If this tag changes climate describe the run(s) done to evaluate the new
+climate in enough detail that it(they) could be reproduced, i.e.,
+- source tag (all code used must be in the repository):
+- platform/compilers:
+- configure commandline:
+- build-namelist command (or complete namelist):
+- MSS location of output:
+
+MSS location of control simulations used to validate new climate:
+
+URL for AMWG diagnostics output used to validate new climate:
