Groups

Groups Tab

The Groups tab lists the Linux user groups associated with Slurm-managed clusters. These groups are crucial for managing user access, job submissions, and resource accounting within HPC environments.

Each group corresponds to a Linux system group that is tied to Slurm user accounts and linked to specific clusters.

Filters

At the top, use filters to refine the group list:

  • Provider: Cloud provider (e.g., AWS)
  • Project: Associated project (if applicable)
  • Account: Cloud account ID used for the cluster
  • Region: Cluster deployment region
  • Search: Click to filter results based on selections
  • Refresh: Reload the current view and group data

Groups List Overview

Functional Overview

  • Each group corresponds to a Linux group created on the compute and head nodes.
  • Users are added to these groups to inherit permission and access configurations.
  • In Slurm, these groups can be tied to:
  • Slurm accounts
  • Fair-share policies
  • Job submission permissions
  • Group membership helps in controlling who can submit jobs, what resources can be used, and how usage is tracked.

Additional Features

  • Search Bar: Quickly search for group names
  • Download Button: Export group data for record-keeping or auditing

Groups Features

📝 Note:
  • These groups directly map to Linux system groups used within Slurm clusters.
  • Proper group-user mapping is essential for correct job accounting, permissions, and policy enforcement.
  • Slurm commands like sacctmgr, scontrol, and system-level groupadd / usermod are typically used to manage these behind the scenes.
  • Users cannot edit or modify policies and groups. These are view-only. To request changes, please contact the system administrator.
  • If you encounter any UI issues or have questions about job submissions or status, please contact the Admin for support.
