Administrator Guide

Administrator Guide#

Configuring and operating a Spur cluster.

  • Configuration Reference (spur.conf) — the full spur.conf reference. Every controller and node setting, with its type, default, and meaning.

  • Roles and operators — User, Coordinator, Operator, and Administrator bindings.

  • Accounting, Accounts, Users, and QOS — managing accounts, users, QOS, associations, and resource limits. Requires a PostgreSQL-backed accounting database.

  • Idle-Fill Scheduling — letting over-quota jobs use capacity nobody with a quota claim wants, and reclaiming it when somebody does. Off by default; enabling it narrows a preemption guarantee.

  • AMD Device Metrics Exporter Integration — attaching per-job labels (job_id, job_user, job_partition) to AMD Device Metrics Exporter GPU metrics via prolog/epilog hooks.

Partitions are defined statically in spur.conf (see Partitioning), not created at runtime.
