Managing Computing Projects
Features of Computing Time Projects
After the application for a computing time project is approved, the project is instantiated and gets the following features:
- A project group.
- The granted computing time.
- Storage space on the file systems.
Project Groups
Computing time projects are often used collaboratively. To facilitate this, each project has an associated group with a unique project-id, which allows for the management of project members. Everyone who is part of the group is allowed submit a computing job that is subsequently billed to the project and to access the project storage space.
Within a group there are the following roles:
- Owner: The person administering the computing time project (either the PI or PC) assumes and permanently holds this role by deault. They can add other members and managers.
- Managers: Individuals with the ability to manage group membership, including adding or removing members and managers.
- Members: Standard participants of the group. Members can always leave a group at their discretion.
The group is managed with the command-line tool member. Key commands include:
- Add a project member:
member add --name <project-id> <user-id> - Remove a project member:
member delete --name<project-id> <user-id> - Assign and revoke a manager role: Append the
--manageroption to the commands above - View group affiliations:

You can find additional information about the tool by using member --man. Please note, executing these commands may prompt you for your password, though subsequent password requests will not be immediate.
For newly added members to fully integrate into the group, initiating a new connection to the cluster is necessary.
End of a Project
Upon the completion of a project at the end of its period, two important processes come into effect:
- Any unused computing time will be forfeited.
- Access to the project's storage space will expire 8 months after the project's conclusion. Please transfer any relevant data within this timeframe. In case you need more time get in contact with us.
