8. CIME user config directory

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>

    This is your project account code for batch submission and/or directory priveleges

  • CHARGE_ACCOUNT=<account number>

    An alternative to PROJECT for batch charging>

  • MAIL_USER=<email address>

    Used 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>
