Overview

This module will manage Open XDMoD. This module works best when paired with Hiera for defining parameter values.

This module is designed so that different hosts can run the various components of Open XDMoD.

Open XDMoD Compatibility

• puppet-module-xdmod 2.x supports Open XDMoD 7.5.x
• puppet-module-xdmod 3.x supports Open XDMoD 8.0.x
• puppet-module-xdmod 4.x supports Open XDMoD 8.1.x
• puppet-module-xdmod 5.x supports Open XDMoD 8.5.x
• puppet-module-xdmod 6.x supports Open XDMoD 9.0.x
• puppet-module-xdmod 7.x supports Open XDMoD 9.5.x

Usage

Examples of some hiera values that may be useful to set globally

xdmod::version: '8.0.0'
# Disable roles that are enabled by default
xdmod::web: false
xdmod::database: false
# Define which features of XDMoD are enabled
xdmod::enable_appkernel: true

# Define site information
xdmod::organization_name: My Org
xdmod::organization_abbrev: MO
# Define resources
xdmod::resources:
  - resource: example
    name: Example
    resource_type_id: 1
    pi_column: account
    shared_jobs: true
xdmod::resource_specs:
  - resource: example

    script_dir: /data/job-scripts/example
# Set parameters used by multiple roles
xdmod::web_host: 'xdmod.domain'
xdmod::akrr_host: 'akrr.domain'
xdmod::database_password: 'xdmod-db-password-here'
xdmod::database_host: 'dbhost.domain'

Example of how to enable OnDemand module:

xdmod::enable_ondemand: true
xdmod::resources:
  - resource: ondemand
    name: OnDemand
    resource_type: Gateway
    shred_directory: /path/to/ondemand/logs/directory
    hostname: https://ondemand.example.com
xdmod::ondemand::geoip_userid: 00001
xdmod::ondemand::geoip_licensekey: secret-key

If you run a local yum repo for XDMoD packages

xdmod::local_repo_name: 'local-repo-name-here'

Enable Federated logins for XDMoD web host

xdmod::web: true
xdmod::manage_simplesamlphp: true
xdmod::simplesamlphp_config_source: 'puppet:///modules/site_xdmod/simplesamlphp/config.php'
xdmod::simplesamlphp_authsources_source: 'puppet:///modules/site_xdmod/simplesamlphp/authsources.php'

Run the XDMoD web interface and AKRR web service with SUPReMM support

classes:
  - 'xdmod'
xdmod::web: true
xdmod::akrr: true
xdmod::database: false
xdmod::enable_appkernel: true
xdmod::enable_supremm: true
xdmod::enable_update_check: false

Host the MySQL databases for XDMoD, AKRR and SUPReMM

classes:
  - 'xdmod'
xdmod::web: false
xdmod::database: true
xdmod::enable_appkernel: true
xdmod::enable_supremm: true

A compute node that will collect PCP data for SUPReMM. The xdmod::supremm::compute::pcp class will declare the pcp class by default. The metrics defined in pcp_static_metrics and pcp_standard_metrics will also define pcp::pmda resources based on which metrics are enabled. See xdmod::params for some defaults. The infiniband, perfevent, nvidia, gpfs, slurm, and mic metrics are commented out.

classes:
  - 'xdmod'
xdmod::web: false
xdmod::database: false
xdmod::compute: true
xdmod::pcp_static_metrics:
  - 'metrics that don't change often go here'
  - '#comments can be defined too and will be present in config file as comments'
  - 'more static metrics'
xdmod::pcp_standard_metrics:
  - 'metrics that change often like during a job'
  - '#comments can be defined too and will be present in config file as comments'
  - 'more standard metrics'

If you wish to use include style class declaration for the pcp class then the default pmlogger and pmie need to be removed and pmlogger_daily in cron needs to have modified arguments.

classes:
  - 'xdmod'
pcp::include_default_pmlogger: false
pcp::include_default_pmie: false
pcp::pmlogger_daily_args: '-M -k forever'
xdmod::web: false
xdmod::database: false
xdmod::compute: true
xdmod::pcp_declare_method: 'include'
xdmod::pcp_static_metrics:
  - 'metrics that don't change often go here'
  - '#comments can be defined too and will be present in config file as comments'
  - 'more static metrics'
xdmod::pcp_standard_metrics:
  - 'metrics that change often like during a job'
  - '#comments can be defined too and will be present in config file as comments'
  - 'more standard metrics'

A host that needs to run the SUPReMM job summarization.

classes:
  - 'xdmod'
xdmod::supremm:: true

A MongoDB host needs to be setup for SUPReMM

classes:
  - 'xdmod'
xdmod::web: false
xdmod::database: false
xdmod::supremm_database: true

Limitations

This module has been tested on:

• CentOS 7
• RedHat 7

Development

Testing

Testing requires the following dependencies:

• rake
• bundler

Install gem dependencies

bundle install
