Elastic High Performance Computing:Create a serverless cluster

Background information

In most cases, Elastic High Performance Computing (E-HPC) clusters use Elastic Computing Service (ECS) instances as compute nodes. You can select the instance types and quantity of ECS instances based on your business requirements and manage the running status of E-HPC clusters and nodes. A serverless cluster uses elastic container instances as compute nodes. The system automatically creates elastic container instances to run jobs based on the jobs that you submit. Each elastic container instance contains one container. After the job is run, the elastic container instance stops billing and is automatically released. If you use a serverless cluster, you do not need to plan for the node capacity in advance or manage the servers. You only need to provide packaged container images to run jobs on elastic container instances.

Prerequisites

• The service-linked roles for E-HPC and Elastic Container Instance are created. When you log on to the E-HPC and Elastic Container Instance consoles for the first time, the system prompts you to activate the service. Follow the prompts to create a 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 top navigation bar, click Cluster.

   4. On the Cluster page, move the pointer over the icon to the right of Create Cluster and click Cluster Template.

   securityGroupId=
   
   [Storage]
   withoutNas=true
   
   [Scheduler]
   schedulerType=ServerlessBatch

   Type	Parameter	Required	Example	Description
   Global	clientVersion	Yes	2.1.0	The version of the E-HPC client. By default, the latest version is used. We recommend that you use the default configurations.
   Node	deployMode	Yes	Managed	The mode in which the cluster is deployed. Set the parameter to Managed.
   Network	vpcId	Yes	vpc-wz9lq2oynq8tia5h8****	The ID of the VPC to which the cluster belongs.
   	vSwitchId	Yes	vsw-wz992iw34x8on06he****	The vSwitch ID.
   	securityGroupId	No	sg-wz94ksuqlwb8iqh8****	The ID of the security group to which the cluster belongs.
   Storage	withoutNas	Yes	true	Set the parameter to true, which indicates that Aspara File Storage NAS is not used as a shared storage when you create the cluster.

5. In the upper-right corner of the page, read and select Alibaba Cloud International Website Product Terms of Service, and then click OK.

6. Go to the Clusters page and view the status of the cluster.

   When the cluster is in the Running state, the serverless cluster is created.
