MACHINE_SPEC_FILE

Overview

CIME looks at the XML node MACHINE_SPEC_FILE in the config_files.xml file to identify supported out-of-the-box machines for the target model. The node has the following contents:

Entry

The following is an entry for MACHINES_SPEC_FILE in config_files.xml.

Only a single value is required.

<entry id="MACHINES_SPEC_FILE">
    <type>char</type>
    <default_value>$SRCROOT/cime_config/machines/config_machines.xml</default_value>
    <group>case_last</group>
    <file>env_case.xml</file>
    <desc>File containing machine specifications for the target model primary component (for documentation only - DO NOT EDIT)</desc>
    <schema>$CIMEROOT/CIME/data/config/xml_schemas/config_machines.xsd</schema>
</entry>

You can supplement what is in the MACHINES_SPEC_FILE by adding a config_machines.xml file to your CIME config directory.

Schema Definition

Version 3

The following is an example of a version 3.0 config_machines.xml file. Version 3.0 breaks machine definitions into separate directories.

<config_machines version="3.0">
  <NODENAME_REGEX>
    <value MACH="docker">docker</value>
    ...
  </NODENAME_REGEX>

  <default_run_suffix>
    ...
  </default_run_suffix>
</config_machines>

For each NODENAME_REGEX entry, there should be a directory named by the value of the MACH attribute.

In these directories is where the machines config_machines.xml, config_batch.xml, and .*.cmake are stored.

The config_machines.xml XML will only contain the machine portion and will omit the NODENAME_REGEX element.

Version 2

The following is an example of a version 2.0 config_machines.xml file. This format provides a monolithic file for all machine definitions.

<config_machines version="2.0">
      <machine MACH="docker">

MPI

There can be multiple mpirun elements. The combination of attributes makes them unique.

Element	Description
mpirun	Top-level element can contain compiler, queue, threaded, unit_testing, or comp_interface attributes.
aprun_mode	If executable contains aprun then this element’s value is used to define the aprun mode.
executable	The executable to run.
arguments	Arguments to the MPI executable.
arg	Argument to the MPI executable.
run_exe	Overrides the default_run_exe.
run_misc_suffix	Overrides the default_run_misc_suffix.

<mpirun compiler="" queue="" mpilib="" threaded="" unit_testing="" comp_interface="">
      <aprun_mode></aprun_mode>
      <executable></executable>
      <arguments>
      <arg position="" name=""></arg>
      </arguments>
      <run_exe></run_exe>
      <run_misc_suffix></run_misc_suffix>
</mpirun>

Aprun

The <aprun_mode> element can be one of the following. The default value is ignore.

• ignore will cause CIME to ignore its aprun module and join the values found in <arguments>.

• default will use CIME’s aprun module to generate arguments.

• override behaves the same as default except it will use <arguments> to mutate the generated arguments. When using this mode a position attribute can be placed on <arg> tags to specify how it’s used.

The position attribute on <arg> can take one of the following values. The default value is per.

• global causes the value of the <arg> element to be used as a global argument for aprun.

• per causes the value of the <arg> element to be appended to each separate binary’s arguments.

Example using override:

<executable>aprun</executable>
<aprun_mode>override</aprun_mode>
<arguments>
      <arg position="global">-e DEBUG=true</arg>
      <arg>-j 20</arg>
</arguments>

Sample command output:

aprun -e DEBUG=true ... -j 20 e3sm.exe : ... -j 20 e3sm.exe

Module System

cmd_path	Path to the module system commands.
modules	Can have multiple where the combination of compiler, DEBUG, PIO_VERSION, mpilib, comp_interface, and gpu_type make them unique.
command	Command to run where name is the action e.g. load, switch, unload and the value is the module to use e.g. netcdf-parallel/3.4
