Email research-computing@uiowa.edu and let us know:
1. Your class name and number. Please include the section number, for example, FIN:1200:0003.
2. How many group folders you want for your class.
ITS - Research Services staff will set up group folders for your class and let you know when the folders are ready.
You can then add students to each group folder using Access Management. Please see details in the section below.
After students have been added to their groups, it will take about 1-2 hours for permissions to propagate through the system. If students have an IDAS session running, they will need to restart their session using the steps here for the changes to be picked up.
Students can access the group folders in inside the classdata folder in the IDAS class instance. For details, please see this section.

The group folders will be set up as follows:

We usually create the folders with the names group01, group02, group03, ... to ensure consistency in naming.
The following permissions are used for the group folders:
1. The instructor of the class is the owner of the folders and has rwx permissions to the folders. The instructor can view, copy and edit files inside the folders.
2. For each group folder:
  1. The instructor can add specific students to each group folder using Access Management, as outlined in the section below. The students who are given access to the folder will have rwx permissions to that folder. Those students can view, copy and edit files inside the folder.
  2. Everyone else in the class will have no permissions to view files inside the folder. That way, only members of a group can view files inside their group folder.
The group folders are created inside the classdata folder, because classdata is a shared location that can be accessed by more than 1 student in the class.

Info
It’s generally not a good idea for different group members to run the same Jupyter notebook in the shared group folder. Doing that can make everyone share the same hidden checkpoints file and can cause some issues. We suggest that each group member keep their own version of the notebook.
