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 default. 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 --manager option to the commands above
View group affiliations: member finger

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.
