Description

This module creates a slurm controller node via the slurm-gcp slurm_controller_instance and slurm_instance_template modules.

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

- id: slurm_controller
  source: community/modules/scheduler/schedmd-slurm-gcp-v6-controller
  use:
  - network
  - homefs
  - compute_partition
  settings:
    machine_type: c2-standard-8

This creates a controller node with the following attributes:

  • connected to the primary subnetwork of network
  • the filesystem with the ID homefs (defined elsewhere in the blueprint) mounted
  • One partition with the ID compute_partition (defined elsewhere in the blueprint)
  • machine type upgraded from the default c2-standard-4 to c2-standard-8

Live Cluster Reconfiguration

The schedmd-slurm-gcp-v6-controller module supports the reconfiguration of partitions and slurm configuration in a running, active cluster.

To reconfigure a running cluster:

  1. Edit the blueprint with the desired configuration changes
  2. Call gcluster create <blueprint> -w to overwrite the deployment directory
  3. Follow instructions in terminal to deploy

The following are examples of updates that can be made to a running cluster:

  • Add or remove a partition to the cluster
  • Resize an existing partition
  • Attach new network storage to an existing partition

NOTE: Changing the VM machine_type of a partition may not work. It is better to create a new partition and delete the old one.

Custom Images

For more information on creating valid custom images for the controller VM instance or for custom instance templates, see our vm-images.md documentation page.

GPU Support

More information on GPU support in Slurm on GCP and other Cluster Toolkit modules can be found at docs/gpu-support.md

Reservation for Scheduled Maintenance

A maintenance event is when a compute engine stops a VM to perform a hardware or software update which is determined by the host maintenance policy. This can also affect the running jobs if the maintenance kicks in. Now, Customers can protect jobs from getting terminated due to maintenance using the cluster toolkit. You can enable creation of reservation for scheduled maintenance for your compute nodeset and Slurm will reserve your node for maintenance during the maintenance window. If you try to schedule any jobs which overlap with the maintenance reservation, Slurm would not schedule any job.

You can specify in your blueprint like

  - id: compute_nodeset
    source: community/modules/compute/schedmd-slurm-gcp-v6-nodeset
    use: [network]
    settings:
      enable_maintenance_reservation: true

To enable creation of reservation for maintenance.

While running job on slurm cluster, you can specify total run time of the job using -t flag.This would only run the job outside of the maintenance window.

srun -n1 -pcompute -t 10:00 <job.sh>

Currently upcoming maintenance notification is supported in ALPHA version of compute API. You can update the API version from your blueprint,

  - id: slurm_controller
    source: community/modules/scheduler/schedmd-slurm-gcp-v6-controller
    settings:
      endpoint_versions:
        compute: "alpha"

Placement Max Distance

When using enable_placement with Slurm, Google Compute Engine will attempt to place VMs as physically close together as possible. Capacity constraints at the time of VM creation may still force VMs to be spread across multiple racks. Google provides the max-distance flag which can used to control the maximum spreading allowed. Read more about max-distance in the official docs.

You can use the enable_slurm_gcp_plugins.max_hops.max_hops setting on the controller module to control the max-distance behavior. See the following example:

  - id: controller
    source: community/modules/scheduler/schedmd-slurm-gcp-v6-controller
    use: [ network, partition ]
    settings:
      enable_slurm_gcp_plugins:
        max_hops:
          max_hops: 1

Note

schedmd-slurm-gcp-v6-nodeset.settings.enable_placement: true must also be set for max-distance to take effect.

In the above case using a value of 1 will restrict VM to be placed on the same rack. You can confirm that the max-distance was applied by calling the following command while jobs are running:

gcloud beta compute resource-policies list \
  --format='yaml(name,groupPlacementPolicy.maxDistance)'

Warning

If a zone lacks capacity, using a lower max-distance value (such as 1) is more likely to cause VMs creation to fail.

TreeWidth and Node Communication

Slurm uses a fan out mechanism to communicate large groups of nodes. The shape of this fan out tree is determined by the TreeWidth configuration variable.

In the cloud, this fan out mechanism can become unstable when nodes restart with new IP addresses. You can enforce that all nodes communicate directly with the controller by setting TreeWidth to a value >= largest partition.

If the largest partition was 200 nodes, configure the blueprint as follows:

  - id: slurm_controller
    source: community/modules/scheduler/schedmd-slurm-gcp-v5-controller
    ...
    settings:
      cloud_parameters:
        tree_width: 200

The default has been set to 128. Values above this have not been fully tested and may cause congestion on the controller. A more scalable solution is under way.

Hybrid Slurm Clusters

For more information on how to configure an on premise slurm cluster with hybrid cloud partitions, see the schedmd-slurm-gcp-v5-hybrid module and our extended instructions in our docs.

Support

The Cluster 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.
