AMD: Resource Manager automatically preempts inactive GPU workloads and returns resources to the cluster shared pool
AMD Resource Manager has gained automatic preemption: it monitors GPU utilization per workload and terminates jobs that fall below a configurable threshold (e.g. 10%) after a set idle timer (e.g. 15 minutes). It offers two policies — preempting only under GPU pressure or always — returning resources held by inactive dev environments to the shared pool.

How does Resource Manager decide which job to preempt?
AMD has added automatic preemption to Resource Manager, the GPU cluster management tool in the ROCm stack. The system monitors GPU utilization per workload and terminates jobs whose activity falls below a configurable threshold (for example 10%) for a set idle timer duration (for example 15 minutes). This way, GPUs tied up by inactive jobs are automatically returned to the shared pool.
Two preemption policies
Resource Manager offers two policies. The default policy, under GPU pressure, preempts inactive jobs only when other workloads actually need the GPU. The second policy, always, preempts inactive jobs regardless of cluster demand. Administrators configure both the activity percentage threshold and the idle timer duration, allowing them to tune aggressiveness to suit their environment.
Why this matters for AI clusters
The feature targets mixed environments where production inference, fine-tuning, and developer workstations share the same GPUs. Without automation, GPUs stuck in idle dev environments and stalled experiments wait for manual operator intervention. Automatic preemption returns those resources without human involvement, increasing the utilization of expensive AMD Instinct accelerators.
Frequently Asked Questions
- What is GPU job preemption?
- Preemption is the automatic termination of jobs whose activity remains below a set threshold for too long, returning the GPU to other workloads.
- What two policies does AMD Resource Manager offer?
- Under GPU pressure (default — preempts only when other jobs need the GPU) and always (preempts inactive jobs regardless of demand).
