Voda scheduler is a GPU scheduler for elastic deep learning workloads based on Kubernetes, Kubeflow Training Operator and Horovod.
Voda Scheduler is designed to be easily deployed in any Kubernetes cluster. For more architectural details, see design.

Elastic training enables the distributed training jobs to be scaled up and down dynamically at runtime, without interrupting the training process.
With elastic training, the scheduler can make training jobs utilize idle resources if there are any and make the most efficient resource allocations if the cluster is heavily-loaded, thus increasing cluster throughput and reducing overall training time.
For more information about elastic training, see Elastic Horovod, Torch Distributed Elastic or Elastic Training.
Voda Scheduler provides several critical features for elastic deep learning workloads as follows:
Checkout the demo to see how resource allocations are dynamically adjusted (and how worker pods are migrated) to maximize cluster throughput
A Kubernetes cluster, on-cloud or on-premise, that can schedule GPUs. Voda Scheduler is tested with v1.20
