Our review
Pros
  • Hierarchical queues, quotas, priorities, and fairness policies
  • Supports gang scheduling, elastic workloads, preemption, and GPU sharing
  • Topology-aware placement with Prometheus GPU allocation metrics
  • Manages GPUs across on-premises, Kubernetes, and cloud environments
  • Supports distributed inference and automatic GPU or worker scheduling
  • Includes RBAC, quotas, metering, and OpenAI-compatible APIs
Cons
  • Requires self-hosted deployment in a Kubernetes cluster
  • Advanced policies may be more than small teams need
  • GPU sharing spans several configuration approaches
  • Its workload scheduler is oriented toward interactive inference
  • The broad control plane may exceed the needs of single-cluster teams
  • GPUStack Enterprise is presented through a contact-sales model
