How do I reserve GPU capacity for recurring training jobs?

To reserve GPU capacity for recurring training jobs, you generally want to use one of these approaches, depending on where you run workloads:

1) Use a fixed GPU reservation or node pool

If you’re on a cloud platform or Kubernetes cluster, create a dedicated GPU node pool and keep it available for your training jobs.

• Pros: predictable availability, simpler scheduling
• Cons: you pay for idle capacity

2) Use scheduled jobs with guaranteed resources

For recurring training, define jobs as scheduled workloads and request specific GPU resources each time.

Examples:

• Kubernetes: CronJob + GPU resource requests/limits
• AWS: scheduled Batch jobs or SageMaker training jobs with dedicated instance types
• GCP/Azure: scheduled pipeline jobs with reserved GPU VM instances

3) Purchase capacity reservations or committed use

If your cloud provider supports it, reserve GPU instances/VMs in advance.

• AWS: Capacity Reservations / Reserved Instances (where applicable)
• Azure: Capacity Reservation Groups
• GCP: committed use discounts don’t always guarantee capacity, so look for reservations or specific zonal capacity options

4) Run a persistent training queue

Set up a queue that always has access to a small pool of GPU machines.

• Good for multiple recurring jobs
• Add autoscaling if workload varies

5) Ask your platform/admin for quota and isolation

If you’re on a shared cluster:

• request dedicated GPU quota
• use taints/tolerations or node selectors
• isolate training jobs from inference/other workloads

Best practice

For recurring training, the most reliable setup is usually:

• a dedicated GPU node pool
• scheduled jobs
• capacity reservation or committed capacity
• monitoring for utilization so you’re not overpaying
