Create a user

Last Updated: Aug 04, 2021

You must create a user in advance to indicate your identity when you submit jobs in the cluster. Elastic High Performance Computing (E-HPC) clusters allow you to create users that have different permissions. This way, administrators and ordinary users can be distinguished.

Procedure

  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 Resource Management>User.

  4. On the User page, select a cluster from the Cluster drop-down list. Click Add New User.

  5. In the Add New User dialog box, specify the user information as prompted.

    User groups are used to control user permissions. The following user groups are provided:

    • Default Authority Group: applicable to ordinary users that need only to submit and debug jobs.

    • Sudo Enabled Group: applicable to the administrator who needs to manage the cluster. In addition to submitting and debugging jobs, users who have sudo permissions can run sudo commands to install software and restart nodes.

      Notice

      Use caution when you grant sudo permissions. A cluster may not run as expected due to misoperations, such as the deletion of an E-HPC software-stack module.

  6. Click OK.
