Elastic High Performance Computing:Create a serverless cluster

Background information

Standard E-HPC clusters use Elastic Compute Service (ECS) instances as compute nodes, which require you to plan instance types and quantities in advance. A serverless cluster uses elastic container instances instead. The system automatically creates an elastic container instance for each job you submit. Each instance contains one container. After a job completes, the instance stops billing and is automatically released. You do not need to plan node capacity or manage servers — just provide packaged container images.

Prerequisites

• The service-linked roles for E-HPC and Elastic Container Instance are created. When you log on to each console for the first time, follow the prompts to create the service-linked role.

• 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.

Limits

The service is not available in the Indonesia (Jakarta) region.

Procedure

1. Go to the template configuration page.

   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, choose Cluster.

   4. In the upper-right corner of the Cluster page, hover over the icon to the right of Create Cluster and click Cluster Template.

2. In the Basic Configurations section, enter the cluster name and logon password.

3. Above the template section, click and select Batch Serverless.

4. Configure template parameters.

   The Batch Serverless template requires the following parameters. Modify the example values based on your business requirements.

   [Global]
   clientVersion=2.1.0
   
   [Node]
   deployMode=Managed
   
   [Network]
   vpcId=vpc-bp156zry1g8y8dv99****
   vSwitchId=vsw-bp1xu3lkc9c9bpq32****
   securityGroupId=
   
   [Storage]
   withoutNas=true
   
   [Scheduler]
   schedulerType=ServerlessBatch

   Type	Parameter	Required	Example	Description
   Global	clientVersion	Yes	2.1.0	The E-HPC client version. The latest version is used by default. We recommend that you keep the default value.
   Node	deployMode	Yes	Managed	The cluster deployment mode. Set this parameter to Managed.
   Network	vpcId	Yes	vpc-wz9lq2oynq8tia5h8****	The ID of the VPC for the cluster.
   	vSwitchId	Yes	vsw-wz992iw34x8on06he****	The vSwitch ID.
   	securityGroupId	No	sg-wz94ksuqlwb8iqh8****	The ID of the security group for the cluster.
   Storage	withoutNas	Yes	true	Set this parameter to true to create the cluster without Apsara File Storage NAS as shared storage.
   Scheduler	schedulerType	Yes	ServerlessBatch	The scheduler type. Set this parameter to ServerlessBatch.

5. In the upper-right corner of the page, read and select the OK, and then click OK.

6. Return to the Cluster page to check the cluster status.

   The cluster is ready when its status changes to Running.
