PCUI - AWS ParallelCluster

PCUI

The PCUI is a web-based user interface that serves as a dashboard for creating, monitoring, and managing clusters. You install and access the PCUI in your AWS account. The PCUI is added with AWS ParallelCluster version 3.5.0.

To install the PCUI and get started, see Installing the PCUI and Configure and create a cluster with the PCUI.

In the PCUI home page, you can create, edit, and delete a cluster You can also view your list of clusters and selected cluster details, and navigate to clusters, official images, custom images, and users.
The PCUI supports the following features:

  • Displays the following:

    • The list of clusters you've created in your AWS account with AWS ParallelCluster.

    • The available status and details for your listed clusters.

    • CloudFormation stack event and AWS ParallelCluster logs that you can use for monitoring.

    • The status of jobs that are running on your clusters.

    • The list of custom images that you can use to build clusters.

    • The list of official images that the UI uses to create clusters.

    • The list of users that have access to the PCUI. You can add and remove users.

  • Provides step-by-step guidance for creating and editing (updating) a cluster and selecting supported cluster features to add, edit, or remove. Inaccessible input fields can't be changed for the cluster configuration being edited. You have the option to perform a dry run validation of your cluster configuration before cluster deployment.

  • Features direct shell links to access the head node in the Clusters view. Choose Add SSM session during the step-by-step guidance to add the direct shell access, and the SSM Managed Instance Core policy on the head node.

Consider the following when using the PCUI to create and manage your clusters:

  • You can only create and edit clusters or build images with the same AWS ParallelCluster version that was used to create the PCUI. Earlier version clusters or images can only be viewed. If you manage multiple versions of clusters and images, we recommend that you create an PCUI instance to support each version.

  • The PCUI is designed to mirror the pcluster CLI functionality. There are some differences. If you align with the step-by-step guidance, then you are using all of the supported features. Before deployment, you have the option to edit the cluster or image configuration manually. If you do this, we recommend that you validate the configuration by choosing Dry run to verify that your edits are fully supported.

Note

PCUI doesn't support AWS Batch.
