Description

This module creates a compute partition that be can used as input to SchedMD-slurm-on-gcp-controller.

Warning: updating a partition will not cause the slurm controller to update its configurations. In other words, it will not update an already deployed Slurm cluster.

Example

The following code snippet creates a partition module with:

  • a max node count of 200
  • VM machine type of c2-standard-30
  • partition name of "compute"
  • connected to the network1 module via use
  • Mounted to homefs via use
- id: compute_partition
  source: community/modules/compute/SchedMD-slurm-on-gcp-partition
  use: [network1, homefs]
  settings:
    max_node_count: 200
    partition_name: compute
    machine_type: c2-standard-30

Support

The HPC Toolkit team maintains the wrapper around the slurm-on-gcp terraform modules. For support with the underlying modules, see the instructions in the slurm-gcp README.

Requirements

Name Version
terraform >= 0.14.0

Inputs

Name Description Type Default Required
bandwidth_tier Configures the network interface card and the maximum egress bandwidth for VMs.
- Setting platform_default respects the Google Cloud Platform API default values for networking.
- Setting virtio_enabled explicitly selects the VirtioNet network adapter.
- Setting gvnic_enabled selects the gVNIC network adapter (without Tier 1 high bandwidth).
- Setting tier_1_enabled selects both the gVNIC adapter and Tier 1 high bandwidth networking.
- Note: both gVNIC and Tier 1 networking require a VM image with gVNIC support as well as specific VM families and shapes.
- See official docs for more details.		 string "platform_default" no
