Description

This module provisions 1 or more PBS Client hosts to submit jobs to a PBS Professional cluster. The following extra services are required:

  • An existing licensed PBS Professional Server; if provisioned in the cloud, we recommend using the pbspro-server module.
  • A shared filesystem mounted across all PBS hosts to facilitate file transfers for jobs and their stdin/stdout logs.

Example

The following example snippet demonstrates use of the client module in concert with the pbspro-preinstall, pbspro-server, and filestore modules.

  - id: pbspro_client
    source: community/modules/scheduler/pbspro-client
    use:
    - homefs
    - pbspro_setup
    - pbspro_server
    settings:
      instance_count: 1
      machine_type: c2-standard-16
      name_prefix: pbs-client

Inputs

Name Description Type Default Required
auto_delete_boot_disk Controls if boot disk should be auto-deleted when instance is deleted. bool true no
bandwidth_tier Tier 1 bandwidth increases the maximum egress bandwidth for VMs.
Using the tier_1_enabled setting will enable both gVNIC and TIER_1 higher bandwidth networking.
Using the gvnic_enabled setting will only enable gVNIC and will not enable TIER_1.
Note that TIER_1 only works with specific machine families & shapes and must be using an image th
at supports gVNIC. See official docs for more details.		 string "not_enabled" no

startup_script Startup script used on the instance string null no
subnetwork_self_link The self link of the subnetwork to attach the VM. string null no
tags Network tags, provided as a list list(string) [] no
threads_per_core Sets the number of threads per physical core. By setting threads_per_core
to 2, Simultaneous Multithreading (SMT) is enabled extending the total number
of virtual cores. For example, a machine of type c2-standard-60 will have 60
virtual cores with threads_per_core equal to 2. With threads_per_core equal
to 1 (SMT turned off), only the 30 physical cores will be available on the VM.

The default value of "0" will turn off SMT for supported machine types, and
will fall back to GCE defaults for unsupported machine types (t2d, shared-core
instances, or instances with less than 2 vCPU).

Disabling SMT can be more performant in many HPC workloads, therefore it is
disabled by default where compatible.

null = SMT configuration will use the GCE defaults for the machine type
0 = SMT will be disabled where compatible (default)
1 = SMT will always be disabled (will fail on incompatible machine types)
2 = SMT will always be enabled (will fail on incompatible machine types)		 number 0 no
zone Default zone for creating resources string n/a yes
