Module Description

Install and configure neos. A tool to launch graphical environment in a slurm job.

The module installs the neos package on the execution and submit nodes. It can also generate a Paraview server file (.pvsc).

Setup

Setup Requirements

Module dependency:

• hpclib
• apache (for neos::web)

Beginning with neos

Usage

neos

Include the neos class on graphical nodes and submit hosts.

The default configuration might be correct for your site, but you should at least provide a cluster name:

class { '::neos':
  config_options => {
    'cluster' => {
      'name' => 'clustername'
    }
  },
}

neos::web

The class ::neos::web should be installed on a web server. This class will setup an alias to a file server.pvsc that will be exported.

The content of the file is:

• Generated from the neos configuration neos_options parameter
• A source for the file
• The content directly

class { '::neos::web':
  neos_options => {
    'cluster' => {
      'name' => 'clustername'
    }
  },
}

Limitations

This module only supports Debian (no RedHat packaging for neos).
