Add User¶

Click on “Add User” at the top right to create another user. The window for creating or editing a user is basically the same. Here, you can choose a role for the user.

^{Figure 4: Add User}

User Logins¶

Click on “Logins” on the grey bar next to “Table” to see which users logged onto the platform on particular dates.

^{Figure 5: User Logins}

Below video shows how to add user and manage them.

3.2. Roles¶

Roles make it easier assign permissions to users. You can give reading or writing capabilities to a particular role and give that role to certain users.

Click on the Roles option in the Administrative Menu to get started.

^{Figure 6: Roles Option}

New Role¶

Click on ”New Role”. Make sure to give a new role a name and description as well as set reading and writing capabilities for the options.

^{Figure 7: Create a New Role}

Roles with Applications and Permisisons.

Applications with Permissions can be added to Roles and users can be assigned to the Roles while creating or while editing a Role

Each role in the page will show the count of Applications and Users.

Right context menu options like Edit, Meta data , Inhert role and Delete options are available for Roles.

Users with Application Permissions¶

The User will be seeing only the applications available in roles with respective permissions.

Metadata¶

Metadata for each Role is now viewable in the sidebar, including permissions and associated users, by clicking on the Role’s name.

Merge Role¶

Selecting two roles now shows a new “Merge” option, allowing you to combine their users and permissions into a single role.

3.3. Teams¶

You can organize your users into teams. Replicate your office or labs’ teams onto the platform so you can stay more focused and efficient.

Click on the Teams option in the Administrative Menu to get started.

^{Figure 8: Teams Option}

Add Team¶

Click on “Add Team” at the top right corner to create another team. In the new window, choose a name, description and users to populate you team.

^{Figure 9: Add a Team}

3.4. HPC Servers¶

Click on the HPC Servers option in the Administrative Menu to get started.

^{HPC Servers Option}

View thumbnails of all your HPC servers and perform actions on them such as viewing utilization, editing, duplicating, exporting or deleting.
