Description

This module creates a slurm controller node via the SchedMD/slurm-gcp controller module.

More information about Slurm On GCP can be found at the project's GitHub page and in the Slurm on Google Cloud User Guide.

The user guide provides detailed instructions on customizing and enhancing the Slurm on GCP cluster as well as recommendations on configuring the controller for optimal performance at different scales.

Example

- source: community/modules/scheduler/SchedMD-slurm-on-gcp-controller
  kind: terraform
  id: slurm_controller
  use:
  - network1
  - homefs
  - compute_partition
  settings:
    login_node_count: 1

This creates a controller node connected to the primary subnetwork with 1 login node (defined elsewhere). The controller will also have the homefs file system mounted via the use field and manage one partition, also declared in the use field. For more context see the hpc-cluster-small example.

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.

Inputs

Name Description Type Default Required
boot_disk_size Size of boot disk to create for the cluster controller node number 50 no
boot_disk_type Type of boot disk to create for the cluster controller node.
Choose from: pd-ssd, pd-standard, pd-balanced, pd-extreme.
pd-ssd is recommended if the controller is hosting the SlurmDB and NFS share.
If SlurmDB and NFS share are not running on the controller, pd-standard is
recommended. See "Controller configuration recommendations" in the Slurm on
