Elastic High Performance Computing:Create a cluster

Last Updated:Jul 19, 2023

Before you use Elastic High Performance Computing (E-HPC), you need to create a cluster. This topic describes how to create an E-HPC cluster in the console.


  • A service-linked role for E-HPC is created. The first time you log on to the E-HPC console, you are prompted to create a service-linked role for E-HPC.

  • A virtual private cloud (VPC) and a vSwitch are created. For more information, see Create and manage a VPC and Create and manage a vSwitch.

  • Apsara File Storage NAS (NAS) is activated. A NAS file system and a mount target are created. For more information, see Create a file system and Manage mount targets.


  1. Log on to the E-HPC console.

  2. In the upper-left corner of the top navigation bar, select a region.

  3. In the left-side navigation pane, click Cluster.

  4. On the Cluster page, click Create Cluster.


    The following section describes how to create a cluster with the simplest configuration. For parameters that are not described in the following section, use their default values. For more information, see Create a cluster by using the wizard.

  5. On the Create Cluster page, configure hardware settings.




    Availability Zone

    Hangzhou Zone I

    The zone to which the cluster belongs.


    For efficient communication between E-HPC nodes, make sure that all nodes reside in the same region and the same zone. For more information, see Regions and zones.

    Pricing Model


    The billing method of the nodes in the cluster. This topic uses pay-as-you-go as an example. You are charged by the hour based on the actual use duration.

    For more information, see Billing method overview.

    Deploy Mode


    The deployment method of the cluster. This topic uses the Standard mode as an example. In Standard mode, login nodes, control nodes, and compute nodes are deployed separately.

    Node type and quantity

    • Compute Node: ecs.gn5-c4g1.xlarge

    • Management Node: ecs.c7.large

    • Login Node: ecs.c7.large

    The instance type and number of nodes. For more information, see Specifications and Best practices for instance type selection.

    • Compute Node: Compute nodes are used to run high-performance computing jobs. The overall performance of an E-HPC cluster depends on the compute node settings.

    • Management Node: Management nodes are used to schedule jobs and manage domain accounts.

    • Login Node: By default, an elastic IP address is attached to a login node. You can remotely log on to a login node and manage the cluster by running commands.

  6. Click to expand Advanced Configurations.





    Network Configuration



    The VPC in which the cluster resides. Different VPCs are logically isolated from each other. If you do not specify these parameters, the first VPC and vSwitch in the VPC and vSwitch drop-down lists are selected by default. Make sure that the number of available IP addresses is greater than that of cluster nodes.




    File System ID

    353 cc4****(Performance NFS)

    If you do not specify these parameters, the first file system and mount target in the File System ID and Mount Point drop-down lists are selected by default. Make sure that the file system has sufficient mount points.

    Mount Point


  7. Click Next.




    Image Type

    Public Image

    Different image types apply to different operating systems.



    When the cluster is created, the cluster nodes apply the operating system and application data of the image.



    The software that handles multiple jobs in a cluster.

    Domain Service


    Manage clusters and cluster users by using the domain service.


    Turn on the VNC switch.

    If you turn on VNC, the system automatically deploys the visualization service when the cluster is created. You can use VNC to connect to a cloud desktop and log on to the E-HPC console.

  8. Click Next.




    Cluster Name


    The name of the cluster. The cluster name is displayed on the Cluster page.

    Logon Password and Repeat Password


    The password of the cluster. This password is required when you use SSH to remotely access the logon node of the cluster. The username is root.

  9. In the Configuration List section, check the settings that you configured. Read and select Alibaba Cloud International Website Product Terms of Service, and click OK.


After you create the cluster, you can check its status on the Cluster page. If all nodes of the cluster are in the Running state, the cluster is created.
