Resource Quotas

Resource quotas is the policy limits that cap how much compute, memory, or storage a user or team can consume - quotas prevent monopolization and enforce predictable multi-tenant capacity governance.

What Is Resource quotas?

• Definition: Hard or soft upper bounds on allocatable resources within scheduler domains.
• Quota Types: GPU count, CPU cores, memory, storage, job concurrency, and queue occupancy limits.
• Enforcement: Scheduler rejects, delays, or downscales jobs exceeding defined quota policies.
• Elastic Option: Soft quotas may allow temporary borrowing when idle capacity is available.

Why Resource quotas Matters

• Fair Access: Prevents one team from consuming disproportionate shared cluster capacity.
• Predictability: Teams can plan around guaranteed baseline resource availability.
• Cost Governance: Quota boundaries align infrastructure usage with budget ownership.
• Operational Stability: Reduces contention spikes that can destabilize cluster performance.
• Strategic Allocation: Supports priority distribution between production-critical and exploratory workloads.

How It Is Used in Practice

• Policy Design: Set quota levels from historical demand, business priority, and budget constraints.
• Borrowing Rules: Define safe over-quota borrowing and reclaim behavior for soft quota models.
• Review Cadence: Adjust quotas periodically based on utilization trends and roadmap changes.

Resource quotas are a core fairness and governance mechanism for shared training clusters - clear quota policy keeps capacity distribution predictable and sustainable.
