Log on to the E-HPC client

Prerequisites

• The cluster and its nodes are in the Running state.

• You have created a cluster user. For more information, see Create a user.

Limitations

• The E-HPC client supports only clusters that use the PBS scheduler. If you have other requirements, submit a ticket.

• The client supports a maximum of 15 concurrent connections to a single cluster. For a higher connection limit, submit a ticket.

• You cannot log on to the client as the root user.

Before you begin

If you are using the E-HPC client for the first time, you must download and install it.

• Running the E-HPC client on your local machine

  Download the client that matches your computer's operating system.

  Operating system	Download link	Description
  Windows	Windows client (Simplified Chinese) Windows client (English)	The client requires Windows 7 or later.
  macOS	macOS client (Simplified Chinese) macOS client (English)	On macOS, you must configure your security settings to allow applications from unidentified developers.

• Running the E-HPC client on Elastic Desktop Service

  1. Log on to Elastic Desktop Service.

     You can access Elastic Desktop Service from various endpoints, such as a software client and a web browser. For more information, see Elastic Desktop Service workflow guide.

  2. Open App Center, find the E-HPC client, and then download and install it.

     Note

     If you cannot find the E-HPC client in App Center, upgrade App Center to the latest version.

Procedure

1. Open the E-HPC client.

2. On the logon page, enter your logon information.

   The following table describes the parameters:

   Parameter	Description
   Server information	Server information consists of the following two parts: Cluster IP address: Enter the private IP or public IP (EIP) of the cluster's logon node based on your network environment. Examples: If you are connecting from your local machine over the internet, use the public IP address (EIP). When you use the E-HPC client from Elastic Desktop Service, you can use the private IP if the networks are interconnected. For example, if the VPC of Elastic Desktop Service and the VPC of the E-HPC cluster are attached to the same Cloud Enterprise Network (CEN) instance, you can use the private IP. Port: The port number is 12011.
   Username and Password	The username and password of a cluster user. You can log on as a user with standard or sudo permissions. You cannot log on as the root user.
   Remember logon information	This option is selected by default. If you clear this option, you must re-enter your password the next time you log on.

   Note

   If you lack the required logon information, contact your administrator. Alternatively, if you have console permissions, you can retrieve the cluster IP address and create cluster users yourself.

3. Click Log on.

   • Upon successful logon, the client's main page appears, which contains modules for tasks such as job query and job submission.

     Important

     After you log on, your session will time out after one hour of inactivity. You will need to log on again.

   • If the logon fails, follow the instructions in the error message.
