Building model

How to build using build.sh from the top-level directory (ie, ufs-weather-model)

• build.sh is a simple wrapper that calls CMake build system

1) load the required modules

  module use modulefiles
  module load ufs_${platform}.${compiler}

• NOTE: On platform GAEA, you must first set up the lmod environment:

   source /lustre/f2/pdata/esrl/gsd/contrib/lua-5.1.4.9/init/init_lmod.sh

2) Build command, one line or multi-line

• export before the call to build.sh, for example:

  export CMAKE_FLAGS="-DAPP=S2S -DCCPP_SUITES=FV3_GFS_2017_coupled,FV3_GFS_v16_coupled"
  ./build.sh

• build using one-line command, several examples:

Build the ufs-weather-model ATM app (standalone ATM):

    CMAKE_FLAGS="-DAPP=ATM -DCCPP_SUITES=FV3_GFS_v16" ./build.sh > output 2>&1 &

Build the ufs-weather-model ATMW app (standalone ATM with waves):

    CMAKE_FLAGS="-DAPP=ATMW -DCCPP_SUITES=FV3_GFS_2017_coupled,FV3_GFS_v16_coupled" ./build.sh > output 2>&1 &

Build the ufs-weather-model S2S app (atm/ice/ocean):

    CMAKE_FLAGS="-DAPP=S2S -DCCPP_SUITES=FV3_GFS_2017_coupled,FV3_GFS_v16_coupled" ./build.sh > output 2>&1 &

Build the ufs-weather-model S2S app (coupled atm/ice/ocean) with debugging flags turned on, with verbose build messages, using a single build job and a specified build directory:

   CMAKE_FLAGS="-DAPP=S2S -DDEBUG=ON -DCCPP_SUITES=FV3_GFS_2017_coupled,FV3_GFS_2017_satmedmf_coupled,FV3_GFS_v15p2_coupled" BUILD_VERBOSE=1 BUILD_JOBS=1 
   BUILD_DIR=test_cpld ./build.sh > output 2>&1 &

Build the ufs-weather-model S2SW app (coupled atm/ice/ocean/waves):

   CMAKE_FLAGS="-DAPP=S2SW -DCCPP_SUITES=FV3_GFS_2017_coupled,FV3_GFS_2017_satmedmf_coupled,FV3_GFS_v15p2_coupled,FV3_GFS_v16beta_coupled" ./build.sh >output 2>&1 &

Build the ufs-weather-model NemsDATM app (NemsDATM/ocean/ice):

   CMAKE_FLAGS="-DAPP=DATM_NEMS" ./build.sh >output 2>&1 &

In each case, the executable will be build/ufs_model

If you edit source code files, just run the same command again. CMake does not need to be cleaned (as much).

compile.sh

• File location is ufs-weather-model/tests
• Sets up environment variables and calls build.sh
• Used by ufs-weather-model/tests/rt.sh

How to feed build options to compile.sh

• For examples, see the second column of rows that start with COMPILE in ufs-weather-model/tests/rt.conf
• Specify components to build, e.g.,
  • -DAPP=S2S (include ATM, MOM6, CICE, CMEPS)
  • -DAPP=S2SW (include ATM, MOM6, CICE6, WAVES, CMEPS)
• Specify CCPP suite name, e.g.,
  • -DCCPP_SUITES=FV3_GFS_v16
  • -DCCPP_SUITES=FV3_GFS_v16_coupled_p8
• Build in debug mode
  • DEBUG=Y
• Putting everything together, e.g.,
  • -DCCPP_SUITES=FV3_GFS_v16_coupled_p8 -DAPP=S2SW
