8. CIME user config directoryΒΆ

CIME recognizes a user-created custom configuration directory, $HOME/.cime. The contents of this directory may include any of the following files:

  • config

    This file must have a format which follows the python config format. See Python Config Parser Examples

    In the [main] block you can set the following variables:

    • CIME_MODEL=[e3sm, cesm]

    • PROJECT=<account number>

      Used to specify a project id for compute accounting and directory permissions when on a batch system.

    • CHARGE_ACCOUNT=<account number>

      Used to override the accounting (only) aspect of PROJECT

    • MAIL_USER=<email address>

      Used to request a non-default email for batch summary output

    • MAIL_TYPE=[never,all,begin,fail,end]

      Any or all the above valid values can be set to list the batch events that emails will be sent for.

    • create_test input arguments

      Any argument to the create_test script can have its default changed by listing it here with the new default.

    • The following is an example config file:

      [main]
      CIME_MODEL=cesm
      SRCROOT=$CIMEROOT/..
      MAIL_TYPE=end
      [create_test]
      MAIL_TYPE=fail
      
  • config_machines.xml

    This file must the same format as $CIMEROOT/config/$model/machines/config_machines.xml with the appropriate definitions for your machine.

    If you have a customized version of this file in the directory $HOME/.cime, it will append to the file in $CIMEROOT/config/$model/machines/config_machines.xml.

    For an example of a config_machines.xml file for a linux cluster, look at $CIMEROOT/config/xml_schemas/config_machines_template.xml.

  • config_compilers.xml

    This file permits you to customize compiler settings for your machine and is appended to the file $CIMEROOT/config/$model/machines/config_compilers.xml.

    The following is an example of what would be needed for customized a ibm compiler flags on a BlueGeneQ machine.

    <?xml version="1.0" encoding="UTF-8"?>
    <config_compilers version="2.0">
       <compiler COMPILER="ibm" OS="BGQ">
          <FFLAGS> -g -qfullpath -qmaxmem=-1 -qspillsize=2500 -qextname=flush </FFLAGS>
          <ADD_FFLAGS DEBUG="FALSE"> -O3 -qstrict -qinline=auto </ADD_FFLAGS>
          <ADD_FFLAGS DEBUG="FALSE" compile_threaded="TRUE"> -qsmp=omp </ADD_FFLAGS>
          <ADD_FFLAGS DEBUG="TRUE" compile_threaded="TRUE"> -qsmp=omp:noopt </ADD_FFLAGS>
          <ADD_CPPDEFS> -DLINUX  </ADD_CPPDEFS>
          <CONFIG_ARGS> --build=powerpc-bgp-linux --host=powerpc64-suse-linux </CONFIG_ARGS>
          <LDFLAGS>  -Wl,--relax -Wl,--allow-multiple-definition </LDFLAGS>
       </compiler>
    </config_compilers>
    
  • config_batch.xml

    This file permits you to customize batch settings for you machine and is appended to the file $CIMEROOT/config/$model/machines/config_batch.xml.

    The following is an example of what would be needed to add batch settings for pbs on the machine brutus.

    <?xml version="1.0"?>
    <config_batch version="2.0">
       <batch_system type="pbs" MACH="brutus" >
          <directives>
             <directive default="/bin/bash" > -S {{ shell }}  </directive>
          </directives>
          <queues>
            <queue walltimemax="00:59:00" nodemin="1" nodemax="624" default="true">batch</queue>
          </queues>
       </batch_system>
    </config_batch>
