Create a cluster

Last Updated: Sep 03, 2021

Before you use Elastic high Performance Computing (E-HPC), you need to create a cluster. This topic provides a quick start for creating a cluster. In this topic, a cluster in which ecs.gn5-c4g1.xlarge compute nodes are deployed and GROMACS is installed is created.

Procedure

  1. Log on to the E-HPC console.

  2. In the top navigation bar, select a region.

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

  4. On the Cluster page, click Create Cluster.

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

    The following table describes the settings used in this example. For parameters that are not described in the following table, use the default values.

    Parameter

    Example

    Description

    Availability Zone

    Hangzhou Zone I

    The zone to which the cluster belongs.

    Note

    To ensure efficient communications between E-HPC nodes, all nodes reside in the same region and the same zone. For more information, see Regions and zones.

    Pricing Model

    Pay-As-You-Go

    You are charged for compute nodes by the hour.

    For more information, see Billing method overview.

    Deploy Mode

    Standard

    The logon node, management nodes, and compute nodes are separately deployed.

    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 logon node. You can remotely log on to a logon node and manage the cluster by running commands.

  6. Click Next.

    The following table describes the settings used in this example. For parameters that are not described in the following table, use the default values.

    Parameter

    Example

    Description

    Image Type

    Public Image

    Different image types apply to different operating systems. The operating systems of all the nodes in a cluster are the same.

    You can select Public Image, Custom Image, or Shared Image.

    Image

    CentOS_7.6_64

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

    Scheduler

    pbs

    The software that handle multiple jobs in a cluster.

    VNC

    Turn on the VNC switch

    After you turn on the VNC switch, the remote visualization window can be automatically deployed.

    Other Software

    • gromacs-gpu 2018.1

    • openmpi 3.0.0

    • cuda-toolkit 9.0

    • vmd 1.9.3

    The software that you need to install on the cluster.

  7. Click Next.

    Parameter

    Example

    Description

    Cluster Name

    gromacs-test

    The name of the cluster.

    Logon Password and Repeat Password

    Ehpc123456

    The password of the cluster.

  8. 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.

Result

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.
