Super Computing Cluster (SCC) is built on Elastic Compute Service (ECS) Bare Metal Instance and is designed to significantly enhance the network performance and acceleration ratio of large-scale clusters by using high-speed Remote Direct Memory Access (RDMA)-based interconnections. This topic describes how to create an SCC instance.
Background information
This topic describes the basic configuration items to consider when you create an SCC instance. For information about other general configuration items, see Create an instance on the Custom Launch tab.
To use RDMA, the High Performance Computing (HPC) scheduler, and the cluster resizing feature, create an SCC and then an SCC instance in the Elastic High Performance Computing (E-HPC) console. For more information, see Create a cluster by using the wizard.
Procedure
Go to the ECS instance buy page.
Configure the parameters described in the following table.
Parameter
Description
Billing Method
The billing and pricing rules as well as the status changes of resources vary based on the billing method. Valid values:
Region
Regions are geographic locations where Alibaba Cloud data centers are deployed. Select the nearest region to your geographic location to reduce latency. After an ECS instance is created, you cannot change its region. For more information, see Regions and zones.
Network and Zone
Specify a virtual private cloud (VPC). VPCs are logically isolated from one another, provide enhanced security, and support features such as Elastic IP Address (EIP), IPv6, and Elastic Network Interface (ENI).
A region consists of multiple isolated locations known as zones. A zone is a physical area with an independent network and power supply. Instances in the same zone share the network and have minimal latency.
Instance
In the Architecture row, select Super Computing Cluster from the High-performance Computing drop-down list. Then, select an SCC instance type. The available instance types vary based on factors, such as the region. On the Instance Types Available for Each Region page, you can view the instance types available in each region. For information about SCC instance types, see Overview of instance families.
After you select an SCC instance type, click the Existing Clusters tab in the Super Computing Cluster section and specify an existing SCC. You can also click the New Clusters tab and enter a name and description to create an SCC.
ImportantInstances in different SCCs cannot communicate with each other. Exercise caution when you specify an SCC. You can confirm the ID of the specified SCC on the Super Computing Clusters page.
Image
Images contain the required information to run instances. Alibaba Cloud provides various images. All available images are displayed in the Image section of the instance buy page.
Configure the parameters in the Storage, Bandwidths & Security Groups, and Management sections.
For more information, see Create an instance on the Custom Launch tab.
In the right-side pane, specify a subscription duration if you set Billing Method to Subscription and confirm that the configurations are correct.
Read and agree to ECS Terms of Service and ECS Refund Policies and Procedure and click Create Order.
NoteECS Refund Policies and Procedure is available only for subscription ECS instances.
It takes 3 to 5 minutes to create an ECS instance. You can view its status on the Instance page in the ECS console. Once created, the instance is in the Running state.
