When running online-cmaq with RUN_TASK_AQM_LBCS and DO_AQM_GEFS_LBCS both set to true, the exregional_aqm_lbcs.sh attempts to execute gefs2lbc_para but places the '-n ${NUMTS}' argument before the executable name. This results, on cheyenne, in a failure of mpirun, because '-n x' is not a valid arg for mpirun.

Expected behavior

The aqm_lbcs task should run successfully with RUN_TASK_AQM_LBCS and DO_AQM_GEFS_LBCS both set to true, if the appropriate input data is provided

Current behavior

The aqm_lbcs task fails, with this message in the log file:

  • exec_fn=gefs2lbc_para
  • exec_fp=/glade/work/paddy/online-cmaq/ufs-srweather-app/exec/gefs2lbc_para
  • '[' '!' -f /glade/work/paddy/online-cmaq/ufs-srweather-app/exec/gefs2lbc_para ']'

Machines affected

The current [develop] branch is proven to fail on cheyenne

Detailed Description of Fix (optional)

Move the '-n ${NUMTS}' argument after the executable name. This fixed the problem for me on cheyenne.

This fixes a problem due to a typo that places the '-n ${NUMTS}' argument before the gefs2lbc_para executable instead of after on Cheyenne for the AQM_LBCS task. The typo causes mpirun to fail on Cheyenne because it's an invalid mpirun argument.
