description: >-
  Volcano is a CNCF incubating batch processing and high-performance computing (HPC) scheduler for Kubernetes. It
  provides advanced scheduling capabilities including gang scheduling, fair-share scheduling, queue management, and job
  lifecycle management for batch workloads such as machine learning training, big data processing, and scientific
  computing. Volcano extends Kubernetes with three CRDs: Job (vcjob), Queue, and PodGroup.

    description: >-
      Volcano extends Kubernetes with CRDs for batch workload management. The Job resource defines batch workloads with
      multiple task types and lifecycle policies. Queue resources manage job scheduling with weight-based fair sharing
      and resource quotas. Volcano supports gang scheduling ensuring all pods in a group are scheduled together, and
      integrates with frameworks like TensorFlow, PyTorch, Spark, and MPI.

    description: >-
      Kubernetes CRD for defining and managing job queues in Volcano. Queues collect PodGroups and support weight-based
      fair-share scheduling and resource quotas, providing the primary mechanism for multi-tenant resource partitioning
      and priority-based job admission.

    description: >-
      Kubernetes CRD that represents a group of pods with strong association, used as the unit of gang scheduling in
      Volcano. PodGroups define the minimum number of pods that must be scheduled together, enabling all-or-nothing
      scheduling semantics for distributed training and computing workloads.
