Polyaxon allows to schedule distributed experiments via the MPIJob, and supports tracking metrics, outputs, and models natively.

Deploy the MpiJob operator

Before you can use the mpijob runtime, you need to make sure that MpiJob operator and the CRD (custom resource definition) are deployed in your cluster.

Enable the operator

To be able to schedule distributed jobs with the MpiJob operator, you need to enable the operator in your deployment config.

You need to enable the operator in Polyaxon CE deployment or Polyaxon Agent deployment:

  mpijob: true

Create a component with the mpijob runtime

Once you have the MpiJob operator running on a Kubernetes namespace managed by Polyaxon, you can check the specification for creating components with the mpijob runtime:

version: 1.1
kind: component
  kind: mpijob

For more details about the specification for creating mpijob runtime, please check please check this section.

Run the distributed job

Running components with the mpijob runtime is similar to running any other component:

polyaxon run -f manifest.yaml -P ...

View a running operation on the dashboard

After running an operation with this component, you can view it on the Dashboard:

polyaxon ops dashboard


polyaxon ops dashboard -p [project-name] -uid [run-uuid] -y

Stop a running operation

To stop a running operation with this component:

polyaxon ops stop


polyaxon ops stop -p [project-name] -uid [run-uuid]

Run the job using the Python client

To run this component using Polyaxon Client:

from polyaxon.client import RunClient

client = RunClient(...)
client.create_from_polyaxonfile(polyaxonfile="path/to/file", ...)
